What is Arginine + Lysine HCl?
Arginine + Lysine HCl is a combination of two amino acids, arginine and lysine, each in their hydrochloride salt form. This combination is commonly synthesized for use in supplements and personal care products.
In hair care products, arginine and lysine might be added for their potential benefits to hair structure and strength. The scientific evidence is somewhat limited, but these amino acids may support the hair's keratin, potentially improving health and appearance.
When you see Arginine + Lysine HCl on a label, it suggests the product may aim to enhance hair vitality and possibly support hair growth, although claims should be treated with caution due to the mixed evidence.
