Peptides have become increasingly popular over the past decade, especially in anti-aging skin products; in some cases, there is actual proof they are effective. So, with peptides impacting the skin, could they benefit hair growth? Experts think it is possible. Thus, research peptides for hair growth might help if the hair is thinning or brows and lashes are getting sparser.

Already there is plenty of hair products that promise to boost hair health. But could the future of hair growth mean hair products contain peptides for scalp health, promoting blood flow and encouraging hair growth? This post looks at the best research peptides for hair growth[1].

What Is Hair Loss?

Hair loss is when hair falls out and new hair does not regrow. Notable signs are the hair becoming thinner on the head, bold spots appearing, and the hairline receding, which gets wider as the years’ pass.

Hair loss [2] is a typical natural problem and occurs in men as they age. It is a stressful condition that can cause mental issues such as anxiety, depression and confidence problems, especially in younger men. And it’s not just a male problem; many women can also suffer from hair loss.

The most common hair loss is AGA (androgenetic alopecia), male pattern baldness and female pattern baldness. AGA [3]is a hereditary condition mainly occurring on the front and top of the head. Pattern hair loss can affect men and women by age 50.

What Is Biomimetic Peptide For Hair Loss?

One of the best study formulas for hair growth is Biotinoyl Tripeptide-1, a tripeptide also called GHK. The tripeptide, or GHK, consists of three amino acids, glycine, histidine, and lysine and is strengthened with the interaction of copper. Scientists believe GHK can signal proteins that work with copper to stimulate the regeneration of old skin cells and make healthier hair and skin. 

Clinical tests show Biotinoyl Tripeptide-1 encourages the cells in hair follicles to boost the production of the essential building blocks of hair, Laminin and collagen. It’s crucial to have Laminin and collagen for the natural regrowth of thick and strong hair.

Tripeptide-1 is a research peptide that promotes fibronectin, collagen and elastin to increase skin firmness and reduce fine lines and wrinkles. It is a common ingredient in moisturizing skin cosmetics and products that reduce dark spots. 

What Are Copper Peptides?

GHK-Cu or Copper Tripeptide-1 naturally occurs in the human body. But, as we age, levels drop and cause the skin to age and other problems like hair loss. As with many research chemicals, scientists have mimicked the natural peptide and created the research peptide GHK-Cu/Copper Peptide[5]. It is a combination of copper and three amino acids. Experts know that GHK-Cu can help with the following problems:

-Improve skin firmness, and elasticity
-Repair protective skin barriers
-Tighten skin and reverse aging skin
-Improve skin and reduce fine lines and wrinkles
-Enhance overall skin condition and look
-Promote wound healing
-Increase hair growth and thickness
-Protect skin from UV radiation
-Reduce free radical damage and inflammation
-Improve results from hair transplant

Can Peptide For Hair Growth Help?

Sadly hair loss is widespread and part of life for men and some women. It is genuinely just a problem most of us have to accept. A lot of the time, it is down to genetics, but it can also happen through illness. Whichever way it occurs, it is a stressful situation that can significantly impact life for men and women.

Fortunately, experts in the research peptide industry are continually searching for a treatment that can reverse hair loss and promote growth. Research peptides have a wide range of uses, and anti-aging is one of them, including promoting hair growth. Several research peptides can prevent hair loss and encourage new growth[6].

Peptides naturally exist in the body and help the body function at a microscopic level. These tiny molecules have a wide range of processes and help link to every organ, including hair follicles. Therefore, experts think peptides can encourage hair growth, similar to the excellent results with peptides treating other aging signs.

Top 5 – Best Peptide For Hair Growth

In the case of hair loss, it can be from genes, hormonal changes, medical conditions and stress. Around the world, billions of dollars are spent annually treating hair loss and growth problems[7].

Experts summarize hair loss in men is due to high levels of anxiety, and in women, its depression. Either way it is a stressful problem, so experts must find a safe treatment to help. Most research peptides are still in the early stages of study and have yet to be approved by the FDA. Here we look at the top 5 research peptides that are showing good results in treating hair loss.

  • GHRP-2 Peptide
  • Ipamorelin
  • TB-500 
  • BPC-157 Peptide
  • CJC-1295

Peptides for Hair Growth GHRP-2 Peptide

GHRP-2 Peptide is a research growth hormone-releasing peptide 2 made in the 1990s to reduce aging problems. It acts as a growth hormone to reduce aging.

GHRP-2 helps stimulate more growth hormones from the pituitary gland and promotes hair growth by regulating Insulin levels Growth Factor 1. A lack of IGF-1 is the main reason for hair loss, but more testing is needed.

Peptides for Hair Growth Ipamorelin For Hair Loss

While we know hair loss is mostly a normal part of aging. It is due to the body not making as much human growth hormone and can lead to muscle loss, weak bones, skin thinness and wrinkles, and poor hair quality. After thirty, levels decrease and cause a decline in health, and the body does not function as well.

Ipamorelin is one of the best anti-aging research peptides. It selects and targets specific areas needing help and promotes the natural process of improving growth hormone levels. In addition to improving skin health, it improves bone health and helps with weight loss.

Peptides for Hair Growth TB-500 The Best Peptide For Hair Growth

TB-500 is a thymic peptide and encourages new hair growth. The role of thymic peptides is to improve the immune system and fight disease. TB-500 is the synthetic version of Thymosin Alpha 1 and ranks as the best peptide for hair growth. It repairs tissue and promotes new cell growth.

Studies show that TB-500 can treat hair loss, infections, and autoimmune diseases. Thymosin Alpha 1 shows exemplary results in preventing hair loss and making new growth.

Peptides for Hair Growth BPC 157 Hair Growth

BPC-157 is a body protection compound that can produce collagen, improving hair health and thickness. Collagen helps promote healthy skin and hair.

BPC 157 is a growth hormone that encourages the pituitary gland to secrete growth hormone to repair organ damage and improve the nervous system. It is one of the best anti-ageing peptides and reduces aging, treats chronic pain from illness.

Peptides for Hair Growth CJC 1295 Peptide

CJC 1295 is a research peptide that works similarly to GHRP-2 and BPC-157 and can promote hair growth by targeting the growth hormone secretagogue. In the peptide industry CJC 1295 repairs tissue, hair follicles, muscle and skin.

With hair growth, CJC 1295 encourages follicle growth while promoting thickness and color. It works differently from other research peptides by releasing human growth hormone over a longer time; therefore, the benefits last longer in the body. There are virtually no side effects with CJC 1295.

Peptides for Hair Growth Best Copper Peptides For Hair Growth

Copper peptides are the top research products that can generate new hair growth. In addition, they improve existing hair making it thicker by boosting the size of hair follicles.

GHK-Cu/Copper peptides[8] improve elasticity and skin plumpness which reduces the appearance of fine lines and wrinkles.

Research copper peptides are becoming a popular subject in the cosmetic market due to their skin and hair benefits.

Copper peptide exists in the body naturally as amino acids and helps make elastin and collagen, to keep skin smooth and firm.

But, as we age, we lose collagen and elasticity through a lousy diet, lack of exercise, sun exposure and smoking. When this begins to happen, certain skin products are available to help get back collagen and elasticity. It’s here where specific research peptides can help.

In the science sector, the GHK-Cu peptide can help. (GHK is glycyl-L-histidyl-L-lysine and binds with copper Cu from the periodic table). Studies show GHK-Cu or copper peptide can increase blood circulation in the skin. 

Copper Peptides Hair Before And After

From research, the copper peptide can support the tissues in the blood vessels, forcing hair follicles to take in more oxygen and nutrients to promote new hair growth. The regrowth from copper peptide can also help the hair’s overall health, stopping it from breaking. In addition, copper peptide can help control hair color, eye color and skin color.  

It’s worth noting that no beauty product can restore collagen and tissue growth once lost. 

Hair loss can mean the hair growth cycle is lessened because of problems with follicles, hormones and more. A considerable benefit of copper peptides in studies is they can extend the growth cycle. Ultimately, this allows more time before hair loss happens.

Copper peptides are showing promising results in improving hair health and skin. They can work with the outer skin layer and help produce more elastin in collagen in the skin tissue. Overall, copper peptides can reduce fine lines and wrinkles, increase collagen, plump the skin, and create firm and smoother skin[9].

GHK-Cu Peptide Benefits 

To summarize, copper peptides rank high among other peptides in repairing skin. 

  • Further studies show they can eliminate skin damage such as acne, sunspots and uneven skin tone.
  • It achieves this by getting rid of damaged connective tissue while at the same time making new.
  • Copper peptides can have antioxidant effects on the skin, reduce inflammation and infections, and prevent more damage.

Small amounts of Copper peptides already exist in many serums and facial moisturizers.

peptides for hair growthOligopeptide-2 Peptides for Hair Growth

Other peptides that show promising results in hair growth are Oligopeptide-2, more commonly known as insulin-like growth factor-1 or IGF-1[11]. The body naturally produces IGF-1 for specific body functions. One of them is boosting hair growth by prompting cell-signal that influences hair follicles.

When hair loss is from hormonal issues, and the standard treatment of DHT blockers or medications with antiandrogenic effects doesn’t work, it might signal the problem lies in the lack of natural IGF-1. Therefore, oligopeptide-2 might be of help. Studies show that oligopeptide penetrates the skin and can increase hair thickness.

Peptides For Hair Growth

In clinical trials[12], GHK-Cu peptide for hair growth provides regeneration properties. GHK-Cu boosts hair growth and density by stopping the creation of the DHT hormone (dihydrotestosterone), which harms the follicle and enlarges the hair follicle[13]. Copper peptides improve blood flow to the scalp and help promote and nourish better healthy hair.

What Peptide Can Help With Hair Growth

While the research GHK-Cu peptide [14] are still in the clinical stages, don’t be too disappointed. There are other treatments on the market that can help. Corticosteroid is available from specialized dermatologists. The treatment is for thinning and baldness every 4-8 weeks.

Steroids are a standard treatment for improving some types of hair loss. These can work for hair loss that happens when the immune system begins to fight with the hair follicles. Typically, the immune system should fight infection, but some hair loss can occur from the body’s immune system fighting with the hair follicle, causing hair loss. The steroids can stop the immune system from destroying the hair follicles.

Micro-Needling Help For Hair Growth

Micro-needling penetrate the scalp, [15] promoting the hair growth of new collagen, and develop new cells that all contribute to new hair growth.

For those suffering from hair loss, Micro-needling can promote thickness to your hair and make it look like a full head of hair. But, the treatment does not promote hair growth or help with the hair loss problem. A hair transplant[16] is the only other help that can give an instant result for hair loss.

Summary: Best Peptides For Hair Growth

However, hair loss happens; it is a stressful situation and affects the person’s entire life. For those men or women who suffer from hair loss, it causes anxiety and depression[16] and stops people from getting on with life. While treatments and options are available to control it, they don’t always work. Some options can solve it completely, such as hair transplant, but they can be expensive. Plus, they sometimes turn out poorly. As for now, research continues with all of the mentioned research peptides we have discussed. So, hopefully, soon, one will be passed for use by the FDA as the new peptide for hair growth
