1, don't tie your hair when you sleep.
Rubber bands can make the hair and scalp compressed, and leave ugly marks on the hair. When you come home from work every day, let your hair down and let your hair and scalp relax, instead of tying it up, especially when you sleep.
2, seize the good opportunity of night hair care.
For severely damaged hair and split ends, night is the best time to repair the damage. Mix a small amount of lemon grass oil or jojoba oil into warm water, then soak the whole hair in it and wrap it with a towel.
