Study Notes
Perming Basics
- Perming is the process of transforming straight hair into curly hair through physical and chemical means.
- The primary ingredient in acid waves is glycerol monothioglycolate, while alkaline waves use thioglycolic acid and ammonia in their formulation.
Perming Process
- Key steps in the chemical phase of perming exclude wrapping hair around the perm tool.
- Neutralizer is critical in the process, as it rebonds disulfide bonds and restores curl shape.
Wrapping Techniques
- Two main wrapping techniques are croquignole and spiral.
- Bookend technique uses a single end paper folded in half; bricklay pattern helps avoid split ends.
- The rectangle wrap is also known as the 9-block pattern.
Curl Formation
- Straight rods yield uniform curls, while large diameter rods do not produce firm curls.
- To create large curls or body waves, large diameter rods are necessary.
pH Levels and Solutions
- Alkaline waves have a pH of 8.0 to 9.5 and are not recommended for porous or damaged hair.
- Acid waves have a pH range of 6.9 to 7.2 and are suitable for color-treated or porous hair.
- Neutralizers typically range in pH from 2.5 to 7.0.
Hair Characteristics
- Hair's porosity affects its ability to absorb moisture and chemical agents.
- Density refers to the number of hair fibers per square inch of the scalp.
- Texture refers to the width of individual hair strands: fine, medium, or coarse.
Chemical Reactions
- Alkaline waves process without heat and create stronger curls, while acid waves require heat for processing.
- Over-processing can lead to frizzy curls, while under-processing can result in weak or limp curls.
Safety Precautions
- Avoid performing a perm on clients with scalp abrasions or who have previously used sodium hydroxide relaxers if they had ammonium thioglycolate.
- Use protective cream on the scalp before applying perm solutions to prevent irritation.
Testing and Processing
- A pull test assesses hair elasticity; a preliminary test curl helps determine the hair's reaction to perming.
- For resistant hair, longer processing times may be necessary.
Post-service Care
- Update client records after each service to keep track of treatment history and outcomes.
- Use acid-balanced neutralizing shampoos post-chemical treatments to re-harden hair.
Relaxing and Curl Reforming
- Sodium hydroxide relaxers (lye relaxers) should not be used on bleached hair.
- During curl reformation, the rod diameter chosen should be at least twice the size of the natural curl for optimal results.
- Curl activators provide moisture and help maintain the shape of newly formed curls.
Additional Tips
- Brushing hair before chemical services should be avoided to minimize irritation.
- Decorative curls can be achieved through proper rod size and wrapping techniques, ensuring the hair is evenly saturated during the process.
