Hair ServicesQuestion 171 of 484
What is the purpose of the neutralizer in a permanent wave service?
a.To clean the scalp before wrapping
b.To rebuild the disulfide bonds in the new curled shape and stop processing
c.To soften the hair so it can wrap around the rod
d.To lift natural pigment for a lighter shade
Explanation
Waving lotion (typically a thio compound) breaks the disulfide bonds so the hair can be reshaped on the rod. The neutralizer (usually a peroxide-based solution) rebuilds those bonds in the NEW curled position and stops the chemical action. Without it, the curl will not hold and damage continues.
