Chemical properties: A peptide of 4 amino acids (Ac-Lys-Gly-His-Lys-NH2); Molecular weight: 509.6 g/mol; Optimal pH: 4.0 - 8.0; Soluble in DMSO.
Properties: Aqueous true solution, emulsion.
Required dosage in cosmetic products: Recommended dosage for preventive care: between 0.5 and 2.5%; Recommended dosage for intensive treatments: between 2.5 and 5%.
Function: Skin protective agent.
Specificities: Anti-inflammatory, hair strengthening, hair densifying, hair regenerating.
Benefits: Recommended for preventing and combating the process of hair loss.
Anti-inflammatory: Reducing local micro-inflammations around hair follicles by decreasing the production of the pro-inflammatory cytokine IL-8, thus reducing the process of hair follicle miniaturization;
Hair Densifier: Stimulating hair growth, increasing the size of hair follicles and making them thicker, thereby ensuring a reduction in the risk of hair loss, by inhibiting the activity of the 5-α reductase enzyme, thus modulating the level of dihydrotestosterone (DHT), the hormone responsible for baldness;
Hair Strengthener: Helps to make hair, eyelashes, and eyebrows stronger, improves the anchoring of hair follicles, and strengthens the hair root by stimulating the renewal of proteins in the extracellular matrix of the follicle surrounding the hair papilla (collagen I and III, laminin);
Hair Regeneration: Ensuring improved regeneration of the hair follicle, which is necessary for initiating a new hair growth cycle, by preserving the activity of the cells in the dermal papilla.
