How can water temperature affect a hair treatment?

The emphasis on how water temperature impacts a hair treatment lies in its effects on the hair cuticle and moisture retention. Hot water can indeed strip moisture from hair, which is detrimental especially during treatments aimed at hydration and repair. This is because hot water can open the hair cuticle, making it more prone to damage and loss of essential oils and moisture.

On the other hand, cold water helps to close the cuticle after washing. When the cuticle is closed, it keeps moisture locked in and prevents frizz, resulting in smoother and shinier hair. This sealing effect can enhance the overall appearance and health of the hair, making cold water an advantageous choice for final rinses after treatment.

Understanding this temperature dynamic is crucial for effective hair care, as it informs the best practices for maintaining hair's health and vitality.
