The potential benefits of pea peptides for hair mainly stem from their rich amino acids and bioactive components, which promote hair health through the following mechanisms:
- Provide the amino acids required for hair
Pea peptides are rich in lysine and arginine, which are important components of hair keratin.
Lysine: promotes collagen synthesis, enhances hair follicle structure, and may reduce hair loss.
Arginine: Helps improve scalp blood circulation and provides more nutrition for hair follicles. - Antioxidant and anti-inflammatory effects
The peptides in pea peptides have antioxidant activity, which can reduce the damage of free radicals to the scalp and hair follicles, and delay hair aging.
May alleviate scalp inflammation (such as seborrheic dermatitis) and indirectly improve hair loss problems. - Promote hair follicle health
Animal experiments have shown that pea peptides may stimulate hair follicle cell proliferation and prolong the hair growth period by regulating growth factors such as IGF-1. - Improve scalp microenvironment
The moisturizing properties of pea peptides may help maintain scalp moisture balance and reduce dryness, itching, and other issues. - Hypoallergenicity
Compared to soy or wheat protein, pea peptides have lower allergenicity and are suitable for people with sensitive scalp.
Current research support
Partial in vitro and animal experiments have shown that pea peptides have a positive effect on hair follicle growth, but human clinical data is still limited and the effect varies from person to person.
How to use it?
Oral supplementation: ingested as a dietary supplement (common dosage is 10-20 grams/day).
External use products: Some hair care products add pea peptides, which may strengthen hair through local effects.
precautions
Pea peptides cannot replace medication for the treatment of severe hair loss (such as androgenic alopecia).
A balanced diet (such as sufficient intake of zinc, iron, and vitamin D) is still the foundation of healthy hair.
