Hot water helps deeply clean but easily causes dry hair
Washing your hair with hot water has a great advantage in cleaning up dirt, excess oil and styling products accumulated on hair and scalp. Hot water has the ability to widen pores, thereby helping shampoo penetrate deep into hair follicles, stimulating blood circulation under the scalp. This process not only helps remove impurities effectively but also promotes hair growth by providing adequate nutrients and oxygen to hair follicles.
However, if you use water that is too hot or wash your hair with high frequency with hot water, the natural oils to protect your hair can be washed away, causing hair to dry, feel dry, brittle, and even peel.
Cold water retains moisture and smoothes hair
Cold water plays an important role in maintaining hair health and shine. It helps tighten the curls of hair, helping hair retain moisture, limiting dehydration and maintaining keratin bonds - an important component of strong and elastic hair. In addition, cold water also helps shrink pores on the scalp, limiting the accumulation of dirt, oil and other impurities, making the scalp cleaner and healthier.
Choose the right temperature to protect hair
The most effective method is to use warm water to clean the scalp, then use cold water to rinse the shampoo and conditioner. This method helps remove dirt while locking in moisture, keeping hair shiny and scalp in optimal care.
