question 35 of 100
if a client has fine brown hair and requests a permanent wave, which type of
perm solution should the stylist select?
select the correct response:
an alkaline perm solution containing ammonium thioglycolate (atg)
an acidic perm solution containing ammonium thioglycolate (atg)
an acidic perm solution containing glyceryl monothioglycolate (gmtg)
an alkaline perm solution containing glyceryl monothioglycolate (gmtg)

Explanation:

Fine hair is more fragile, so a gentle acidic perm with GMTG is ideal. Acidic perms have a lower pH, cause less damage to fine hair, and GMTG is a milder reducing agent compared to ATG, making it suitable for delicate fine brown hair. Alkaline perms are too harsh for fine hair as they can over-process and damage it.

Answer:

an acidic perm solution containing glyceryl monothioglycolate (GMTG)
