LYE or No LYE Relaxers?
Lye relaxers do not straighten the hair as completely as no lye relaxers. Disulfide bond breakage is reduced because the chemical's aggressiveness tends to put time constraints on the straightening process. However, while the bonds responsible for the curl/coil of the hair are left intact, other critical hair bonds are destroyed on the external layers of the hair.
No lye relaxer formulas are best for self-relaxers or "do-it-yourselfers," people who have fine hair, children, and those with sensitive scalp conditions. They are also better for those who prefer a straighter relaxed hair turnout.
