Hair Straightning

It is accomplished using a hair iron or hot comb, chemical relaxers, Japanese hair straightening, Brazilian hair straightening, or roller set/blowdryer styling. In addition, some shampoos, conditioners, and hair gels can help to make hair temporarily straight.

It can be achieved with alkaline creams containing up to 3.5% sodium hydroxide (lye-based straighteners), or else guanidine hydroxide, potassium hydroxide, or lithium hydroxide in place of sodium hydroxide (non-lye straighteners).
