Hydrolysed Keratin Peptides

What are Hydrolysed Keratin Peptides?

Hydrolysed keratin peptides are derived from keratin, a structural protein naturally found in hair, skin, nails, feathers, wool, and horns. Hydrolysed keratin peptides are made through a controlled hydrolysis process where the large keratin protein is broken down into smaller peptides and free amino acids. This improves solubility and bioavailability, making it suitable for use in dietary supplements, functional foods, and cosmetic formulations.

Health Benefits:

Boosts Hair Health

Hydrolysed keratin peptides can provide various benefits for hair health and appearance by increasing hair strength, thickness and shine. Keratin is the primary structural protein in hair, and therefore by taking a highly bioavailable hydrolysed keratin peptides supplement the body is able to absorb and utilize it to repair and reinforce hair structure from within. These peptides may also help prevent UV damage to hair which is linked to dry and brittle hair susceptible to breaking. Furthering this, research has shown that MELATINE® (a hydrolysed keratin peptide ingredient) can stimulate the activity and regeneration of keratinocytes, which in turn promotes healthy strong hair and reduces hair loss.

Reduces Grey Hairs

These peptides may also help control emerging grey hairs, as clinical research found that Melatine® significantly darkened hair colour after 120 days. Moreover, through stimulating melanogenesis, hydrolysed keratin peptides may help to offset the development of new grey hair which occur from non-functional melanocytes.

Supports Skin Health

Hydrolysed keratin peptides may provide benefits for the appearance and health of skin, potentially helping to reduce signs of aging, strengthening the skin barrier and enhancing elasticity. One study found that the oral supplementation of keratin hydrolysate over 90 days was associated with improvements in the appearance of facial skin of adult women with increases in skin smoothness and decreased well of wrinkle depth and length in the “crow's feet” area.

Typical Use:

Hydrolysed keratin peptides are often used in supplements aimed at supporting hair, skin and nail health. In such supplements, these peptides are frequently incorporated into formulations alongside ingredients such as zinc, selenium, collagen peptides and vitamin C. Alongside their use in dietary supplements, hydrolysed keratin peptides also have various topical applications, as they are widely used in shampoos, serums and nail treatments.
