Polyquaternium37 Impact on Hair
Today there is something called Polyquaternium-37, which cannot be ignored in the hair. Its problems are quite obvious in the hair. It may make the hair withered and lose its moist state, like grass on dry soil, lacking vitality and no smooth quality. Or it may cause it to be fragile and easy to fold, and if it touches an external force, it will fall off one after another, and the weak branches are still unable to withstand the wind and rain. This Polyquaternium-37 has damage to the nourishment and toughness of the hair, so it should be used with caution for the maintenance of the hair.
