questions and answers
Eumelanin - (correct answer) -produces brown to black pigments in the hair
Pheomelanin - (correct answer) -Produces yellow to red pigments in the hair
medulla - (correct answer) -deepest layer consisting of round cells
Developers - (correct answer) -are oxidizing agents
amino acids - (correct answer) -the building blocks of proteins in the hair
Hydroxide Neutralization - (correct answer) -helps restore the pH in the hair
and neutralizes any remaining alkaline left by a hydroxide relaxer
chemical relaxing - (correct answer) -chemically alters naturally wavy or
curly hair into a straight form
pH - (correct answer) -ranges from 0-14 measuring acid, alkaline or neutral
ammonium thioglycolate (ATG) - (correct answer) -combination of ammonia
and thioglycolic acid reducing agent
Lanthionization - (correct answer) -Process where a hydroxide relaxer
removes one atom of sulfur from a disulfide bond ( which makes a
lanthionine bond)
Salt bonds - (correct answer) -side bonds are easily broken by change of pH
to reform when pH balance is restored
base cream - (correct answer) -The product protecting the scalp from
irritation in a relaxer service is known as:
no base - (correct answer) -which relaxer DOES not require base cream for
skin or scalp ?
base relaxer - (correct answer) -a relaxer that DOES require the application
of base cream:
hydrogen bonds - (correct answer) -which bond is broken by heat or water ,
then reformed when hair cools and dries?
