5. You’re scrubbing the scalp with your nails.
Vigorously scrubbing the scalp can cause abrasions and it could cause eventual scalp infections. Hair is more fragile when it’s wet, and aggressive scrubbing can cause tangles, breakage, and can even weaken the follicles. The best way to wash your hair is to gently massage the roots with your fingers and palms.
6. You’re washing your hair with hot water.
The best water temperature for washing your hair is lukewarm. Washing the hair with hot water can make your locks easy to break and weaken the roots. Slightly warm water helps open the hair cuticles, and the hair absorbs the oil and moisturizing effects of the conditioner better. It’s best to finish the routine by rinsing your hair with cold water, as it will help close the cuticles and keep your hair from turning frizzy.
