Washing Hair In Cold Water?

Fact or Fiction?                        

This is an idea that’s been around for a long time: rinsing hair with cold
water will cause it to shine more. Anecdotally, the reasoning is that rinsing
hair with cold water will make the cuticles of your hair lie flatter and reflect
more light. There is a lack of scientific evidence to support this belief.
Rinsing hair with cold water will certainly wake you up, but a scientifically
proven (and much more comfortable!) way to make the cuticle smooth is to use the
proper conditioner for your hair structure every time you shampoo.


Verdict: Unproven

My opinion: I have tried rinsing my hair with cold water but it always seemed to make ot hard and knot up. It was not a success for me. I use lukewarm water and hot water dries my hair. No shine here.
