Wash your hair with conditioner only. Also called "co-washing," this technique is used to keep your hair clean and moisturized. Wet your hair, then apply the conditioner and allow it to work its magic for about five minutes, and then rinse it out. Since shampoo strips the moisturizing oils out of locks, which can cause it to get dry and tangled, using conditioner only about once a week during your stretch period keeps your hair as manageable as position during this time.
Straighten your new growth with a flat iron. Doing so helps it blend into the straightened portion of your hair, so the line of demarcation -- where your new growth hits your old growth -- isn't so noticeable. Use this method sparingly, however, as your fragile hair can break with excessive use.
Moisturize your mane regularly. Working an ultra-hydrating moisturizer, such as coconut oil, on your new growth and scalp a few times a week can soften new growth and help keep it strong, preventing your locks from breaking off. It also smells super yummy so you won't even have to wear perfume.
Run a wide-toothed comb through your tresses daily to prevent them from becoming tangled. Not combing your 'do can result in matting, which is not only unsightly, but seriously painful to get out.
Some gals prefer to keep their hair protected in braids or twists during their stretch period. This is perfectly fine, as long as they aren't too tight, which can cause damage to your 'do.
