Keratin is a protein that the human body creates itself. It is a vital part of the structure of nails, hair and skin. Keratin production can be affected due to a range of factors, including hormones and environmental conditions. Due to a lack of keratin, nails go brittle and weak—keratin treatment rise as a solution here. The keratin treatment kit consists of brushes on products with keratin that bond with the natural keratin of nails. Along with keratin, the treatment also includes nourishing agents like natural oils to condition nails.
