Shiny hair is linked to expensive products, but one of the most talked about secrets is far simpler and cold water. Many swear that cold rinse at the end of a wash instantly boosts shine and smoothness while others call it a beauty myth.



What Cold Water Actually Does To The Hair Cuticle

Rinsing of cold water

Cold water tightens the hair cuticle making it lie flat which traps in the moisture inside and boosts shine by reflecting light reducing frizz and helps the hair color lasts much longer.



What Cold Water Actually Does Hot water lifts the overlapping scales aka cuticles of the hair while cold water helps the hair lie down flat, creating a very smoother surface.

• A flat cuticle reflects the light much better giving it a more glossy healthy look.


• Hot water reduces frizz as it seals the cuticle as less moisture escapes and less humidity gets in, minimizing flyways.


• It locks in moisture which traps the cuticle that helps in retaining the hair's natural oils and conditioning treatments.


• Any smoothing or shine from a cold rinse is often temporary, with the cuticle to its normal state as hair dries.

How To Use Cold Rinse The Right Way

Condition the hair properly

To use cold rinse the right way, wash and condition with lukewarm water first and then switch to a cool and not icy cold rinse it after 30-60 seconds at the very end to close the cuticles, lock in moisture, boost shine reduce frizz, focusing on sealing in conditioner and color and not cleansing as cool water does not dissolve dirt well.




Key Tip: Use lukewarm water for cleansing and conditioning to open cuticles for product penetration and finishing with a cools or cold rinse to tighten the cuticle for shine and smoothness.
