Stronger and more suitable for coarse and moisture-resistant hair. Their active ingredient is ammonium thioglycolate (ATG).
Alkaline perm
compounds typically found in progressive color and some over-the-counter hair dyes that can react to the chemicals used in relaxer and perm products.
Metallic Salts
The most common perm rod type. They have a smaller diameter in the center, increasing to a larger diameter on the ends.
Concave rod
apply around the client’s hairline to keep the solution from dripping down the client’s face
Cotton coil
These are necessary to control the hair’s ends when winding the hair on the perm rods.
End papers
They are more ideal for fine, color-treated, and fragile hair. Their common active ingredient is glyceryl monothioglycolate (GMTG).
Acidic Perm
If too many disulfide bonds are broken, the hair may not hold the desired curl.
overprocessed hair
Usually about 12 inches (30.5 centimeters) long with a uniform diameter along the rod’s entire length.
soft bender rods
Use for added skin protection around the hairline, the nape, and the top and back of the ears
Base or barrier cream
determined by your client’s final desired curl
Rods
Active Ingredient: Mercaptamine/cysteamine
Thio free wave
the hair’s ability to stretch and return to its original length without breaking.
Elasticity
These are long, cylindrical rods that are usually longer than standard.
spiral perm rods
Use to section hair.
Plastic rattail comb
uses only one end paper placed over the top of the base panel of hair.
Flat wrap
Active Ingredient: Monoethanolamine (MEA)/aminomethylpropanol (AMP)
Ammonia free wave
indicates the condition of the cuticle layer and its ability to absorb and retain moisture.
Porosity
After the hair is wrapped, secure the rod by fastening the ends together to form a loop.
loop rod
must be worn to protect your hands from skin damage, chemical absorption, and possible contact dermatitis development
Gloves
Uses one end paper folded in half over the hair ends.
Bookend wrap
Active Ingredient: Glyceryl monothioglycolate (GMTG)
True acid wave
If too few disulfide bonds are broken, the hair will not be sufficiently softened.
underprocessed hair
equal in diameter along their entire length or curling area, producing a uniform curl shape along the strand’s entire width.
straight rods
use to wet the hair if it dries out during the wrapping process
Spray bottle
A perm wrap in which one end paper is placed under and another is placed over the hair’s base panel (subsection) being wrapped
Double Flat wrap
