Water Temperature to Wash Hair
A: For the average person, who simply wants to shampoo his or her moderately soiled hair, warm water is the way to go. Warm water allows the shampoo to most effectively remove the dirt and oils in the hair, and helps the conditioner smooth the hair and rinse away cleanly.
The heat and moisture help to expand the cuticle layer somewhat and can help conditioners to penetrate more deeply when applied to hair warmed by hot water. In these cases, the conditioner should be rinsed using tepid or cooler water.
Cold water rinses after shampooing and conditioning help to tighten up the cuticle layer and can be beneficial for those who have problems with an oily scalp and oily hair. The cold water helps to tighten pores and slow down oil production in the skin for a period of time following the rinsing.
