The best water temperature for washing hair is typically lukewarm to slightly warm. Here’s why:
Lukewarm Water (Ideal):
– Helps to cleanse the scalp and hair without stripping away natural oils.
– Opens the hair cuticle just enough to allow for effective cleaning and absorption of conditioner.
Hot Water:
– Can strip the hair and scalp of natural oils, leading to dryness and potential irritation.
– Can cause the hair cuticle to open too much, which might lead to frizz and damage.
Cold Water:
– Can help to seal the hair cuticle after washing, making hair look shinier and smoother.
– Might not be as effective in thoroughly cleaning the hair and scalp.
A good routine could be to wash with lukewarm water to clean and condition the hair, and then rinse with a cooler temperature to help seal the cuticle and add shine.
