Improving Hair Growth with Skin Remodeling Copper Peptides

Loren Pickart PhD

When we are young, our hair is thick, well-pigmented and grows rapidly on our head. But with the passage of time, the hair thins or vanishes, growth slows, and becomes grayer. While the search for methods to restore healthy, younger hair is ancient, the reality is that, even today, in the era of minoxidil (Rogaine) and finasteride (Propecia), all existing therapies give at best a marginal restoration of hair health.

Skin remodeling copper peptides, or SRCPs for short, are the latest candidate being tested for the improvement of hair health. What are SRCPs? They are types of copper peptides that are based on a human copper peptide complex called glycyl-l-histidyl-l-lysine:copper (II) or GHK-Cu for short. See Figure 1.

Figure 1 Legend: Solution structure of GHK-Cu

GHK-Cu is a normal component of human blood plasma, urine, and saliva. (1) It is increasingly being used in products sold for reversing the effects of aging on human skin. SRCPs are defined as having actions similar to GHK-Cu which include anti-inflammatory effects, skin repair actions, and the ability to increase the size of hair follicles. It should be emphasized that not all copper-peptides have such positive actions; indeed, some copper-peptides can inhibit these effects. (2-4)

Causes of Hair Thinning and Loss of Vitality

Before discussing the use of SRCPs on hair, it is best to first focus on the causes of hair thinning and loss in healthy humans. These causes are more diverse than generally realized although most attention has been focused on blocking the actions of DHT (dihydrotestosteone). For example, most theories of hair loss and thinning hair have focused on the metabolic actions of DHT, but in reality, other factors can also induce or modulate these effects. So it is best to consider each factor that influences hair growth separately.

DHT The actions of the androgens testosterone and DHT are major factors in scalp hair growth and male pattern baldness (androgenetic alopecia). Such androgens also stimulate axillary, pubic and beard hairs to grow. However, hairs such as eyebrows and eyelashes are not regulated by androgens. Testosterone is enzymatically converted by 5-AR to DHT in the hair follicle and DHT is thought to be the major factor in male pattern baldness.

But many men have high testosterone metabolite levels but never suffer hair loss. The ultimate factor in hair loss appears to be not DHT itself, but damage to the hair follicle. A recent study of 3,000 individuals found no link between baldness and the genes (5-alpha reductase) controlling the the production of testosterone metabolites. (5,6) Some researchers are of the opinion that if follicular health is improved or maintained, it is possible that hair loss can be reversed or minimized.

Miniaturized follicles At age 15, hair follicles actively produce thick, heavy terminal hair for about 3.6 years during the anagen phase then shrink during the dormant telogen phase for about 4 months. As we age, the follicle's anagen phase progressively shortens while the telogen phase lengthens. The net result is a progressive shrinkage of follicle size during the anagen phase and this produces thinner, slower growing hair. (5,6) Hair conditioners are used to thicken the hair shaft with fats and proteins to give the appearance of fuller, more-youthful hair.

Increase in length of dormant follicle phase While this change is usually attributed to DHT actions, other factors such a damage caused by excessive heat, coloring agents, and relaxers may also produce follicle damage that results in less functional follicles.

Inadequate follicle microcirculation The synthesis of new hair necessitates a very high nutrient flow to the follicle bulb. Morphological studies often observe a markedly diminished capillary blood supply in aged, miniaturized follicles. This alone may be the cause of follicle miniaturization and inadequate hair syntheses. (5-7)

Inflammation around follicles Many dysfunctional follicles appear to have an auto-immune inflammation around the follicle. It has been proposed that follicular inflammation is the final step in the sequence of events that ultimately produces inactive follicles that are incapable of producing thick, terminal hair. (5-7)

Decreased subcutaneous fat layer The layer of fat at the base of the skin, also known as subcutaneous adipose tissue or colloquially called baby fat, diminishes with age. Researchers have noted the accumulation of this fat around healthy follicles that are vigorously growing hair, and its relative lack in around dormant follicles, and have postulated that these fat cells serve a supportive function for the hair follicle. Conditions that inhibit hair growth such as chemotherapy or starvation, also decrease the subcutaneous fat layer (5-7).

Damage from relaxers, excessive heat, coloring agents and dyes Numerous common procedures damage scalp health and hair follicles. Scalp damage from relaxers, permanents, color cosmetics with their organic dyes and metallic salts, and excessive heat from blow dryers and hot oil treatments that can literally boil the follicles, all can combine to damage the hair follicle and reduce hair growth. This is often most noticeable in women as a decrease or loss of eyebrows and eyelashes by age 40.

Lack of sulfur donors Hair is composed of 35% sulfur containing amino acids. Only feathers in birds have similar levels of such amino acids. Nutritional surfer supplements such as MSM (methyl sulfonyl methane) have long been used to improve the hair coats of racehorses and are increasingly being used to improve hair health in humans.

Graying of hair The hair colors are produced in pigment cells in the follicles. The amino acid tyrosine is converted by the copper-containing enzyme, tyrosinase, into black pigments called melanin or eumelanin and a reddish pigment, produced by a separate gene, called heomelanin (or sometimes called phaeomelanin). In most persons, hair color slowly decreases with age and may vanish to produce white hair in the elderly.

Excessive hair cutting Dr. George Michael (founder of the George Michael Long Hair Clinics) emphasized that longer hair is healthier hair. It is possible that hair follicles require some tension produced by the weight of a heavy hair shaft in the same manner that muscles and bones whither when not stressed and exercised. Michael remembered that, in the Russia of his youth, women in their sixties often had healthy, waist-length hair. Later, when he worked in New York City, he found that virtually no women of this age possessed such healthy hair.

SRCPs to Stimulate Hair Growth

One of the more exciting developments in skin research in recent years is the finding that hair follicles are the source of stem cells for the skin. (8,9) But long before these discoveries that linked hair follicles and skin repair, I had observed that, after treating skin wounds with GHK-Cu, that there was a profound enlargement of the hair follicles of the skin at the wound edge. To develop these discoveries for commercial uses, in 1985 I started a company called ProCyte. Further work with radioisotopes in mice indicated that the SRCP was present at the site of injection for only about 30 seconds before being cleared from the area. This meant that a very brief exposure of the follicle to the SRCP was sufficient to produce an increase in hair follicle volume of 4 to 8-fold and increased hair growth within 12 days.
See Figure 2.

Figure 2 Legend. A 25 day-old mouse was shaved and injected intradermally in three spots with a SRCP. Twelve days later, there was a very strong stimulation of hair growth at the injection sites.

Further work by Steven Lovejoy (University of Washington) and myself found that the chemical addition of fat-like molecules, such as fatty acids or hydrophobic amino acid residues, to GHK-Cu, resulted in an intensified follicle enlargement action and more strongly stimulated the rate of hair growth in young mice. Even in undamaged mouse skin, one intradermal injection of the SRCPs induced accelerated hair growth after twelve days. Work with radioisotopes indicated that the SRCPs was present at the site of injection for only about 30 seconds before being cleared from the area. (10)

These discoveries were later verified and extended by Hideo Uno at the University of Wisconsin. Uno had written The UpJohn Company's textbook for physicians when Rogaine (minoxidil) first was marketed. Using hair growth models in mice and rats, Uno found that SRCPs convert fine, short vellus hairs into thicker pigmented terminal hairs.

Uno studied the details of hair stimulation by SRCPs in C3H mice and Fuzzy rats by 1) phototrichogram, 2) folliculogram (micro morphometric analysis), and 3) the rate of DNA synthesis in the follicular cells. He found that in C3H mice, the SRCPs stimulated of the follicular cell proliferation, resulting in an enlargement of the anagen follicles from vellus types that produce small, thin hair to terminal follicles that produce thick, long hair. type The SRCPs also maintained follicles in the anagen phase longer. In Fuzzy rats, a genetic strain that has only short vellus hair, the SRCPs had the effect of enlarging the small vellus follicles. (11-12).

Also of interest were studies by Awa and Nogimori of Kaken Pharmaceuticals reported, that in mice, pretreatment with SRCPs blocked hair loss induced the cancer chemotherapy drugs cytosine arabinoside and doxorubicin. If mice were first treated with chemotherapeutic drugs to induce hair loss, subsequent treatment with SRCPs accelerated the recovery of lost hair. (13)

Bernard Kalis (University of Reims) was the first to demonstrate that SRCPs also had positive actions on hair follicle functions in humans. His studies used phototrichogram analysis that found SRCPs caused a greater proportion of human follicles to switch from the dormant telogen state into the hair-growing anagen state. (14) A later placebo-controlled, three-month study in male humans found a SRCP (Ala-His-Lys: copper(II)) in a product called Tricomin increased the terminal hairs and was 32% more effective than the control group that used 2% minoxidil in this study. (15)

Hideo Uno has commented that while minoxidil primarily stimulates new vellus hair growth, the SRCPs are more effective in the conversion of vellus hair into terminal hairs and suggested that the combined use of minoxidil and SRCPs would have a synergistic actions and be most effective. See Figure 2.

Note Figure 3 is self explanatory about the actions of minoxidil and SRCPs.

SRCPs and Hair Transplantation

Another developing use for SRCPs is their use to improve human hair transplantation. GraftCyte, a copper peptide product sold by ProCyte, when used in the post-operative regimen results in faster healing of transplants and earlier regrowth of the hair shafts. GraftCyte is sprayed on the wound area after transplants. Controlled studies by Perez-Meza et al found that the GraftCyte system provided enhanced healing of the transplanted follicle and less post-operative hair shedding along with a more immediate hair growth. Patients see new hair growth in 6 weeks, versus the normal 10 to 14 weeks of other procedures. The normal skin crusting after transplantation has been reduced from 10 to 14 days to 5 days in most cases. (16).

A second controlled study of Graftcyte by Gary Hitzig on 30 hair transplant patients found that Graftcyte reduced percent of patient with shedding of transplanted hair from 30% with saline to 10% with Graftcyte. The time to healing of the transplant wounds using Graftcyte and Dr. Hitzig's procedure was 10-14 days with saline and 5-10 days with Graftcyte. Regrowth of new hair from the transplants occurred in 6-8 weeks with saline and 4-6 weeks with Graftcyte. Patient satisfaction after transplantation rose from 80% to 95%. (17) Graftcyte can be obtained from www.procyte.com.

Improving General Hair Vitality with SRCPs

While the above studies were encouraging, it is also apparent that the SRCPs are not miracle hair growth therapies. A more important future use of SRCPs may as a regular scalp treatment or hair tonic, used once or twice weekly, for the general improvement of hair and scalp health. SRCPs have numerous actions that may improve hair health. See Figure 4. These include:

Note Figure 4 is self explanatory about aging and follicle damage.

Reduce DHT formation in the hair follicles 5-alpha reductase exists in 2 forms; type 1 which function in hair follicles and type 2 which acts in prostate tissue. Follicle damaging DHT is produced in the hair follicles. Propecia (finasteride) inhibits 5-AR throughout the body and improves hair growth. But it works best on the type 2 form, and is best suited for for controlling prostate enlargement. It also must be administered by pills that spread the drug throughout the body. However, increased copper ions in the skin is better at inhibiting the type 1 5-AR that damages hair growth. Sugimoto et al (Sugimoto 1995) found that copper (II) ions could give up to a 90% inhibition of type 1 5-AR. at At 0.12 micrograms copper ion per milliliter, there was a 50% reduction in activity of type 1 alpha reductase but copper (II) ions were 10-fold less active on inhibiting the type 2 prostate type. Thus, copper ions are more specific inhibitors of 5-AR than finasteride. (18)

Human transdermal studies have found that concentrations up to 0.50 micrograms of copper ion can be introduced into the skin with SRCPs without skin irritation. For comparison, the blood plasma copper level is approximately 1 milligram per milliliter.

Improve Microcirculation to Hair Follicle Hair follicles have very high rates of metabolic activity. However, morphological studies of aged follicles often find an inadequate capillary circulation and some have suggested that the resultant lack of nutrient flow may be a causative factor in the thinning of hair shafts with age. SRCPs have angiogenic activity may possibly correct this problem. (2)

Protective Anti-inflammatory Actions The final event in the sequence of degenerative changes that produce involuted non-functional hair follicles are tissue-damaging auto-immune inflammatory and free radical reactions around the follicle. SRCPs may reduce such effects since they block both the inflammatory actions of both interleukin 1and TGF-beta-1 actions in inflammation. (19-21) Also during tissue injury, the release of ferrous iron from ferritin increases the formation of tissue-damaging free radicals, but SRCPs block the release of iron from ferritin. Finally, copper, zinc superoxide dismutase (SOD) is normally only about 50% activated due to a lack of copper in the protein. SRCPs can supply additional copper to SOD and increase its anti-oxidant effectiveness. (22)

Autoimmune damage causing hair loss exists in conditions such as alopecia areata, diabetes, vitiligo, certain types of thyroid disease, and pernicious anemia. The treatment for these conditions is usually a short course of any cortisone-type drugs which often restores hair growth. But cortisone injections into the bald spots bring the hair back only temporarily. The problem is that costicosteroids inhibit skin repair and often produce and thinner, less functional skin that is less able to support hair follicle functions. In studies on nickel allergy patients, Zhai et al wrote that SRCPs to be as potent as cortisone in reducing redness and inflammation while also stimulating skin repair in nickel allergy patients. (23)

Enhancement of the skin's subcutaneous fat layer and thickening of the scalp During human aging, there is a thinning of the scalp. Part of this is due to a diminishment of the scalp's subcutaneous fat layer that surrounds the hair follicles diminishes with age. Pathologists have noted that large subcutaneous fat cells are associated with large, healthy hair follicles and are postulated to provide nutritional support to the follicles. Conditions that cause hair loss such as cancer chemotherapy are associated with a sharp decrease in the volume of subcutaneous fat cell. SRCPs increase both the hair follicles size and the amount of subcutaneous fat. (24)

SRCPs also help increase skin thickness by increasing the dermal levels of collagen, elastin, and the water-holding proteoglycans and glycosaminoglycans. (2-3)

Repair of Damaged Scalp Hair loss, especially in women, may often be caused by scalp damage from relaxers, permanents, coloring chemicals, and excessive heat from blow dryers and hot oil treatments. This is often evident in women who have seriously thinned eyebrow by age 40 after decades of application of color cosmetics. SRCPs might be used after various hair procedures to speed repair of scalp damage.

Reduce Graying of Hair - Hair becomes gray with age but the speed that this happens may depend on the adequacy of available copper in the scalp. Melanin and other hair pigments are produced from the amino acid tyrosine by the action of tyrosinase, a copper-containing enzyme. Additional scalp copper might slow this graying process and some have often reported the re-pigmentation of gray hair after using copper peptide products.

Future Development of SRCPs for Hair Health

While research between 1983 and 1991 established the potential uses of SRCPs, it also became apparent that much more effective and stable SRCPs were needed to develop practical and truly effective products. Therefore, in 1994, I researched the development of improved SRCPs.

Previously when I was at ProCyte, I had used chemical modifications of molecules to create more-active SRCPs. But the problem with this chemical approach is that the human body often has difficulty metabolizing alien molecules. Peptides from soy protein digests have a long history safe use in products ranging form solutions used for intravenous alimentation to hair conditioners used to add body to hair. We isolated a special from the soy protein digests. When this fraction when chelated to copper (II) produces a very strong stimulation of hair growth in standard models in mice, strongly stimulated skin rebuilding, and had anti-inflammatory actions. (23,25-28)

To enhance the uptake of SRCPs into the skin and hair follicles, we focused on natural penetrating agents such as emu oil or squalane from olives to push more SRCP into the skin. Others also are testing the use of encapsulating the SRCPs in newer types of advanced liposomes to increase potency.

There is also the possibility that some variant of SRCPs could be used to induce hair follicle multiplication. Often during studies in mice, we have observed what appeared to be an increased production and density of hair follicles. This effect was often observed during skin transplantation experiments and may more complex than the more simple enlargement of hair follicle size that we most often observed. See Figure 5. Dermatological dogma is that hair follicles never multiply but, in the era of stem cells and DNA cloning, anything is possible.

Interview with Loren Pickart PhD

- Mr. Pickart, am I right that you were the first scientist who started research on Copper-Peptides and there was nothing known about them before?

- I would not say that proteins associated with copper were completely unknown. Chemists had been investigating the ability of copper to make complexes with some peptides. And there is a lot of research on copper and enzyme superoxide dismutase. But this molecule, the model of which I'm holding now (Seen Here), was unknown to scientists.

It all happened in 1970s when I was working at the University of California at San Francisco. It was time of great belief in medicine. Many scientists wanted to do big things, such as fighting cancer. I decided to find the way to reverse human aging.

We worked with blood cells and discovered that young cells contained some Copper-Peptide complex. We found out, that old cells lasted longer if we supplied them with this peptide complex. But it took us 15 years to understand how they work. Now we know that Copper-Peptides work as a restorative signal in skin, bones, and hair follicles. And it is possible that they work the same way in other tissues.

- So they work as growth factors?

- Not exactly. Let us look at wound healing. After damage, there are mostly destructive and sterilizing processes involving free radicals. Then cells begin to release transforming growth factor TGF-beta-1 that stimulates scar formation. But damaged tissue also releases Copper-Peptides. At some point their concentration reaches the level where they suppress TGF-beta-1 production and block oxidation.

- I have read that free radicals could be a restorative signal and because of this too much antioxidants might delay wound healing.

- I believe in good oxidation. You can accelerate wound healing by applying oxidizing agents first and Copper-Peptides second.

- In your article you are saying that Copper-Peptides work as antioxidants and anti-inflammatory agents; they also inhibit scar formation, stimulate angiogenesis, attract macrophages to wound, stimulate hair follicles, speed up both collagen destruction and new collagen synthesis...

- Yes, that's correct. They remodel skin, you may say that they turn off destruction and turn on reparation.

- It is hard to believe that one molecule can be so powerful.

- We hardly could believe it too. But numerous other laboratories all over the world extended our observations. French scientists found that Copper-Peptides stimulate nerve growth, scientists from National Cancer Institution researched angiogenesis, scientists from Utah investigated antioxidant capacity of this molecule and so on.

- We keep talking about medical use, but now they are used in cosmetic industry.

- Yes, initially we developed these products for medical use, but physicians don't like trying new inventions; they prefer well-known remedies. Besides, the procedure of drug approval is ridiculously complicated in USA. It takes years and you have to spend a fortune. It is much easier to get approval for cosmetic products, and women love to explore new cosmetics. I can assure you, that many cosmetic products already contain the medicine of the future, because their developers do not want to bother with drug approval. But I agree that unlike drugs, cosmetic products should be perfectly safe. We tested Copper-Peptides and didn't find any toxicity, any side effects. They are safe, and they are meant to be safe, because they are found in human body and they don't modify any physiological processes in skin. They protect skin and give the signal to restoration. Don't you think it is perfect role for cosmetic ingredients?

- You mean that there is no risk of scar formation or inflammation even if people use high concentrated products?

- On the contrary, Copper-Peptides prevent scars and inflammation. Some women report disappearance of stretch marks and scars.

- It seems that your product affects the skin physiology after all. But FDA still requires cosmetic products to be inert in skin.

- There are no such things as inert cosmetic ingredients. All substances that we put on our skin, such as Vaseline and other emollients (even plain water) affect skin in some way. And people in FDA understand this. They also understand that modern people want cosmetics to improve skin, to make it better. I have no doubt that the definition of cosmetics will be changed soon.

- Today many cosmetic companies make cosmetics using your Copper-Peptides. Do you believe they use efficient concentrations of Copper-Peptides?

- Unfortunately many cosmetic companies just don't care. They want a popular ingredient on the label and that is all. But some companies make very good products and spend a fortune on testing. It is not only a matter of concentration, it is important to know how Copper-Peptides will behave in a complex mixture, and how a technical process will affect them. That is why dermatological testing of finished products is so important.

- It seems for majority of cosmetic manufacturers it is still easier to make fake claims rather than develop potent cosmetic products?

- Unfortunately it is true. But this situation is changing now. The more great cosmetic products come to the market, the closer the future in which only efficient cosmetics will be profitable.

- As I understand, your company does a very little manufacturing, and your main occupation now is still science of reversal of skin aging. But don't you ever dream to be famous with your own cosmetic line?

- Yes, I have been thinking about this a lot. But I prefer to be a scientist. Manufacturing and promotion of new cosmetics is a tough business. I'm 65 years old and I want to enjoy life.
