There are several reasons why frizz is a natural occurrence for afro hair. These reasons include the weather, an ineffective hair routine, your hair type, and hair damage.
All afro curly hair is naturally porous and is always attracted to moisture. So, in humid climates, you may experience more frizz than normal as your curls will try to absorb as much water as possible from the air surrounding you.
To maintain your natural texture while sleeping, you need a night haircare routine to help you keep your curls free from frizz, breakage, and tangles. Whether you have relaxed or natural afro curls, this routine could include preserving your hair intact in a satin or silk bonnet or scarf at night.
