Cold water makes your hair look healthier and shinier. As a matter of fact, cool air makes your hair shinier too (that’s why there is a cool air button on your hair dryer). What the cold water does is that it closes the cuticle which makes the hair stronger and prevents dirt from easily accumulating within your scalp. Basically, the same principle with how it closes the pores of your skin as mentioned above. Stronger hair, of course, prevents hair from being easily pulled out when you are combing, and it helps in slowing down overall hair loss.

So if the 'pores' on your hair follicles are closed, it's not as textured so it's shiny and smooth :) Haha it's kind of a confusing answer but basically no, it doesn't damage your hair at all :) [ Hitoast's advice column | Ask Hitoast A Question ]
