Nails

Nails grow slowly — around three millimetres a month on the hands, and slower on the feet. As with hair, any change shows only after several months, with the new part growing from the base while the old part travels out. Biotin contributes to the maintenance of normal nails and is the best-known ingredient in this category. Zinc contributes to the maintenance of normal nails and to normal protein synthesis. Selenium contributes to the maintenance of normal nails. Collagen and protein supply the basic amino acids; iron comes into play where there are deficiencies. Nails that break often may simply reflect too much contact with water and detergents. If changes in shape or colour are sudden or pronounced, it is worth asking a doctor. The products in this category are below. Where to start: gloves for washing up and a hand cream after every wash resolve more cases than people expect, and cost little. The BioHack generator builds a protocol around the goals you choose and says how long to wait before expecting a change.
