Definition
A semi-essential amino acid containing sulfur that helps build proteins, protects cells from damage, and is crucial for hair, skin, and nail health.
Etymology
From Greek 'kystis' (bladder), named because it was first isolated from bladder stones in the early 1800s.
Kelly Says
Cysteine is unique because it's one of the few amino acids that can form disulfide bonds with itself, creating the permanent waves in hair—this is literally the chemistry behind perms, and it's why hair is so structurally different from other proteins.
