Question

why we should not wash our hair in warm water???

Answer 1

Not only does it close the pores,it also closes the hair cuticle, sealing in moisture from the conditioner that u applied to your hair. Whereas hot Water can remove the moisture from hair,cold water retains the moisture and the natural sebum that's so beneficial

Answer 2

Because of the damage it can do to one's scalp , causing hair follicles to weaken and hair to fall out. ... To protect our hair , try to wash our hair in warm water instead of hot and rinse with cooler temperatures to steal moisture into our hair and prevent breakage . "
