For several years. Your hair is the most fragile of all hair types. They snap & break easily. So you need more TLCs than thin hair. No chemicals. No relaxers specially! No heating styling tools. Finger comb is best or use a wide tooth comb. Do what Oprah & Michelle Obama have been, going natural, using plastic curlers to set their hair. Use oil or conditioner to keep them moisturized. Heat & chemicals are your hair's worst enemies. The relaxers are still in your skin, they also contain formaldehyde causing cancer, and they just don't fade, you need to take foods high in anti-oxidant foods to help you get them out of your system. ANTIOXIDANTS FRUITS: Cranberries, blueberries, and blackberries ranked highest among the fruits studied. Apples ran a close second, and dried fruits were also leading contenders. Peaches, mangos, and melons, while scoring lower than berries, still contain plenty of antioxidants as well as other nutrients. Make a smoothie.
The hair of many black women is very fragile and studies have demonstrated that normal brushing and combing the hair can result in breakage. Brushing your hair 100-times a day is a no-no for your hair. Only comb and brush your hair to style it. Also avoid rubber bands or other implements that can physically cut into and break the hair shaft.
