HOT WATER can interfere with chemical hair processes. After a chemical service like coloring, perming, or relaxing, using hot water can open the hair cuticle too much, leading to faster color fading, dryness, and breakage. It’s better to use lukewarm or cool water, which helps seal the cuticle and preserve the treatment’s longevity. Cool water also locks in moisture, keeping the hair healthier and shinier.
