The pH value is between 0 and 14 where 7 is considered neutral. Healthy hair has a pH between 4.5 and 5.5 but damaged hair has a value greater than 7.0.
Healthy hair has a compact, smooth and therefore shiny cuticle, and this guarantees a good level of resistance and elasticity, in addition they have a uniform level of porosity and therefore represent the ideal basis for chemical treatments.
Damaged hair has a raised cuticle and a dull surface, this tends to make the hair knot increasing the risk of breakage, moreover the hair is very porous which does not allow to guarantee a uniform treatment.
BALANCER pH 2.5 is a color balancer, he balances the pH values after the chemical treatment.
Its formula containing cetrimonium chloridedevelops a remarkable de-alkaline and detangling action, eliminates the alkaline residues present in the scalp and hair, thus restoring the physiological pH of the hair.
