This catch-all nail treatment is a welcome addition to any nail care routine, but it can be especially beneficial for those who experience lots of breakage, peeling, discoloration, or ridges after ruling out a potential health concern with their doctor. Garlic also contains other cysteine, which can help maintain healthy skin and help the body metabolize biotin.

The keratins include the following proteins of which KRT23, KRT24, KRT25, KRT26, KRT27, KRT28, KRT31, KRT32, KRT33A, KRT33B, KRT34, KRT35, KRT36, KRT37, KRT38, KRT39, KRT40, KRT71, KRT72, KRT73, KRT74, KRT75, KRT76, KRT77, KRT78, KRT79, KRT8, KRT80, KRT81, KRT82, KRT83, KRT84, KRT85 and KRT86 have been used to describe keratins past 20.

The more flexible and elastic keratins of hair have fewer interchain disulfide bridges than the keratins in mammalian fingernails, hooves and claws (homologous structures), which are harder and more like their analogs in other vertebrate classes. [24] Hair and other α-keratins consist of α-helically coiled single protein strands (with regular intra-chain H-bonding), which are then further twisted into superhelical ropes that may be further coiled. The β-keratins of reptiles and birds have β-pleated sheets twisted together, then stabilized and hardened by disulfide bridges.

Sunflower seeds are rich in biotin, containing 2.6 mcg of biotin per 0.25 cup, providing 9% of the DV. Cysteines are also important for forming collagen, maintaining the skin’s elasticity, and metabolizing biotin so the body can use it. Zinc

Several diseases, such as athlete's foot and ringworm, are caused by infectious fungi that feed on keratin. [33]Moll, Roland; Divo, Markus; Langbein, Lutz (June 2008).

Nails are primarily made of a fibrous structural protein called keratin. This is what gives nails their strength and resilience. It also protects your nails from damage or stress ( 12, 13).
