Should You Wash Hair With Warm Or Cold Water?
It is recommended to wash hair with warm water as it can help to open up the hair cuticles and allow the shampoo and conditioner to penetrate deeply into the strands for effective cleansing and conditioning. However, using cold water for a final rinse can help to seal the cuticles, which can make hair shinier and smoother. It ultimately depends on personal preference and hair type but using lukewarm water for shampooing and cold water for rinsing is a popular choice.
