Question

What Hair Conditioners consist of Cysteine amino acid? (it's for a biology project. Please only respond if you know the answer)

Answer 1

Answer:

Some 18 amino acids can be found in the hair, such as proline, threonine, leucine and arginine. Keratin is particularly rich in cysteine (a type of sulfurated amino acid), which forms disulfide bonds between molecules, adding rigidity and resistance to the entire structure.
