What Is the Cysteine Treatment?

Cysteine is an amino acid (non-essential type) that helps make protein and our hair is made up of a protein called keratin. (Sass, J O et al. “Trichothiodystrophy: quantification of cysteine in human hair and nails by application of sodium azide-dependent oxidation to cysteic acid.” Archives of dermatological research vol. 296,4 (2004): 188-91. doi:10.1007/s00403-004-0483-2) Over time, this keratin decreases and our hair tends to become dry, damaged and frizzy.

Thus, getting the cysteine treatment done will involve straightening the hair using cysteine, which helps replenish the lost protein in the hair and thereby can improve its condition.

This treatment is one of the latest hair smoothening treatments and is fast gaining popularity because it is claimed to be even more effective than the keratin hair treatment.
