Curl On biologic is amino-acid based and develops its reducing action through a lab-developed natural ingredient obtained from the modification of “Cystine” amino-acid. Cystine is an amino-acid which can be found in human hair keratin. Curl On biologic exploits a natural amino-acid with modified chemical composition.
USE: Curl On biologic can be used as a traditional alkaline perm. The only recommendation is not to use heat sources.
