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 every time you shampoo.
Verdict: Unproven
