5 True/False questions
Once the solution is in the cortex → Breaks disulfide bonds by adding hydrogen atoms to the sulfur atoms.
Keratin → Long, coiled polypeptide chains
Metallic salts → Mix 1 oz of 20v peroxide with 20 drops of 20% ammonia. Immerse 20+ strands of hair n the solution for 30 minutes. Slight lightening = no metallic salts. Rapid lightening and foul smell = metallic salts
Has a tight, compact cuticle that resist penetration → 7.8 and 8.2
The amount of processing during a permanent wave is determined by the → a. Exactly what the client expects
b. What is possible
