Make Waves
This is how many turns to unwind the curl in order to do a proper test curl.
2-3 turns
This is what must be used in order to protect your client from direct contact with the chemical cape.
Neck strip
This relaxer is also known as a lye relaxer.
Sodium hydroxide
Due to the increased blood circulation this causes, it can cause irritations more quickly. Therefore, you need to ask your client about their consumption of this during your consultation.
Caffeine
The most common neutralizers contain this ingredient.
Hydrogen peroxide
This type of permanent wave is activated by an outside heat source- typically a hooded dryer.
Endothermic waves
This is what the cosmetologist should be using on every perm in order to prevent 'fishhooks'.
End papers
This is the type of relaxer that has the highest incidence of curl reversion.
Ammonium sulfite/ ammonium bisulfite
Your client has tightly curled hair and is requesting a chemical texture service to give them a larger curl pattern. Based on this information that you gathered during their consultation, this is the service you should perform.
Soft curl perm
This is what you are doing if you combine a thio relaxer solution with flat ironing.
Japanese Thermal Straightening
If, after completing the permanent waving process, your client has hair that is curlier at the scalp and straighter at the ends, you can assume this has happened.
Overprocessed the hair
This type of perm rod has a smaller diameter in the center and a larger diameter on the ends.
Concave rods
This relaxer is formulated with a protective base that melts at body temperature.
No-base relaxer
If your client has longer, thicker hair, and is requesting a uniform curl from scalp to ends during their consultation, this is the type of perm/ wrap you should use.
Spiral wrap
This is how perm rods should be wrapped in order to minimize the stress and tension on the hair.
half off-base
*perpendicular to the base section
Properly processed perms should break and rebuild this percentage of the hair's disulfide bonds.
50 %
This is what is used in order to determine the base section's size.
The length and width of one perm rod
This is the common term for the types of relaxers that are the best choice for clients with sensitive scalps.
No-lye relaxer
Due to the fact that some of these can affect your hair, alter the perm results or cause breakage, you should always ask your clients about their use of this.
current medications
This is the process in which a hydroxide relaxer removes a sulfur atom from a disulfide bond and converts it into a new type of bond, leaving the hair straight.
Lanthionization
If a mild perm solution is used on coarse hair, there may not be enough of these to break the necessary number of disulfide bonds.
Hydrogen ions
This is the main active ingredient in acid waves.
Glyceryl monothioglycolate (GMTG)
These are the two types of relaxers that are chemically incompatible and should NEVER be used on the same head of hair.
Sodium hydroxide and thio relaxer
CCCA or central centrifugal cicatricial alopecia is a form of alopecia that results in permanent hair loss. If your client has this, they are not a candidate for a chemical relaxer. These are the symptoms they would be experiencing if they have it.
Burning, tingling, 'pins and needles' and scalp tenderness.
*it my also present as crust or pimples that look inflamed.
The lower the porosity, the ____________ the ___________ needed to lift the cuticle layer and deposit texture solutions within the cortex where the relaxing takes place.
Higher / Alkalinity
