Those wavy new roots that are growing in don't have to ruin the sleek look of your relaxed hairdo. You should start to see new growth at the roots in about four weeks after getting your hair relaxed. According to the U.S. Food and Drug Administration, you should wait six to eight weeks between hair-relaxing processing treatments. This leaves you to think of creative ways to deal with the new wavy growth that is showing at the root of your hair. Usually, keeping the new growth moisturised will help it to relax enough naturally so that it won't be as obvious.
Massage a quarter-sized amount of pure coconut oil into your scalp and onto the new hair growth after you shampoo and while the hair is still damp. This will add moisture and soften the new hair growth so it will loosen its curls.
Pour olive oil into a squirt applicator bottle (the kind that is used to apply hair dye) using a funnel.
Part your hair with the applicator bottle by drawing a line down your hair with the bottle tip. Gently squeeze the bottle to apply a light amount of olive oil in a faint line down the part, as you drag the bottle tip through. Repeat on your whole head.
Gently comb the oils through your hair with a wide-toothed comb. Put your hair in a protective style such as a bun or braids while trying to hide wavy, new growth. This style will give support to the brittle and easily-broken line of demarcation where the relaxed hair ends and the new growth starts. The longer your hair grows, the more stress is put on that line.
Wet hair and shampoo as usual. Towel dry hair very gently, patting it dry, not rubbing.
Apply a deep conditioning treatment following the directions on the bottle. This should be done once a week. Wrap your hair in a towel to keep it warm and from dripping on you.
After 10 minutes (or the amount of time directed on the package) rinse the conditioner out of your hair. Carefully comb it using a wide-tooth comb and allow it to air dry.
Wash your hair no more than two to three times a week to keep from drying it out unnecessarily.
Treat the demarcation line (where the new growth is forming) very gently when combing or the hair could break at that point.
