Synthetic Polymer Hair Conditioners are designed for use on very badly damaged hair. A polymer is a compound consisting of many (poly) repeating units which create a chain.
When the hair which is a natural polymer, is so severely damaged that it cannot be conditioned by normal protein conditioners, a synthetic polymer may be necessary to prevent breakage and correct excessive porosity.
Daily Hair Tip
If you lie on your back while you sleep this could cause hair stress leading to split ends in the back. To avoid hair stress tie hair back using a soft scrunchie band.
