What is peptide?
Peptides or glycyl-L-histidyl-L-lysine (GHK) are short chains of about 2-50 amino acids, which are the "building blocks" of proteins. They are often found in foods, supplements, shampoos and play a major role in fighting infections and healing wounds. In many cases, peptides are also applied directly to the skin.
In hair, peptides act as a signal to the body to produce keratin, which helps grow the hair shaft and hair fiber. Taking peptides orally may help reduce hair loss and thinning associated with hair loss.
What role do peptides play in hair growth?
Stimulates hair follicles: Two proteins, collagen and elastin, are important for hair and scalp health. In order for the body to produce these two substances, peptide supplementation is essential. Peptides help prolong the hair growth phase, improving hair density.
Improved blood circulation: Peptides help increase blood circulation to the scalp, allowing hair follicles to receive more oxygen and nutrients. This in turn helps hair growth by nourishing the hair follicles.
Blocking DHT (dihydrotestosterone): The hormone dihydrotestosterone or DHT plays a role in solving problems related to hair loss in both men and women. This hormone shrinks hair follicles causing hair to thin, by blocking the development of DHT, peptides prevent hair loss.
Reduces Inflammation: Scalp inflammation can lead to hair loss, peptides can prevent this from happening by soothing the scalp and reducing redness. Peptides also help keep hair moisturized and prevent dryness and flaking of the scalp.
How to use peptides for hair
Peptides are commonly found in many shampoos and conditioners or in serums.
- Apply a few drops of peptide-containing serum to the scalp.
- Use fingertips to gently massage evenly into hair.
- Leave on hair and no need to wash off after application.
