In determining which relaxer to use, the stylist must always perform a skin test on the subject. A skin test will determine if the subject is sensitive or allergic to the chemical. A skin test is performed by taking a very small amount of the chemical, less than a smidgen, and rubbing it on the inside of the forearm and leaving it there for 24 hours. If any redness at all occurs that you must not use the product on the subject.
There are some relaxers that are especially for new growth only. Luster PCJ Smooth Roots relaxer is one such product. It is the only children’s relaxer kit that is especially designed to touch up new growth. When her growth gets about ½ inches to ¾ inches long, it’s time she gets a touch-up. A touch-up, when done at the right time can reduce hair breakage. The Smooth Roots product straightens and conditions new growth with a triple-action conditioner and it works no matter what relaxer you have used in the past.
