The benefits of phytokeratin for nails.

Keratin is a sulfur-rich fibrous protein that forms the outermost layers of the epidermis and appendages (nails, hair, and fur). Generally, the keratin used in cosmetics is of animal origin. At Typology, we have chosen to opt for a plant-based alternative: phytokeratin, referred to as Hydrolyzed Wheat Protein or Hydrolyzed Sweet Almond Protein on I.N.C.I. lists.

This is a fine beige powder composed of hydrolyzed wheat or almond proteins,meaning they are broken down into smaller proteins that will thus have better penetration and interaction at the surface of the skin, hair, and nails. Phytokeratin is obtained through a enzymatic process.

The nail is a horny plate primarily composed of keratin but also of mineral salts (potassium, calcium...). During the growth of the nail, the keratinocytes present in the basal layer, inside the nail, gradually traverse the different layers to reach the surface. During their ascent, the keratinocytes load up with keratin.

Thus, theintroduction of phytokeratin (which has a structure very similar to natural keratin) to the nailstrengthens brittle, soft, and weakened nails. It helps to improve nail growth, their strength, and protects them from external aggressions.
