Study Notes
Sodium Hydroxide Relaxers
- Have an alkaline pH of 11.5-14.
- Commonly known as lye relaxers.
- Typically used on tightly curled hair.
Ammonium Thioglycolate Relaxers
- pH level ranges around 8.5 to 9.5.
- Strength labeled as mild is ideal for healthy, color-treated, fine-textured, or porous hair.
- Also utilized for curl reformation and softening hair.
Relaxer Application
- An acid-balanced neutralizing shampoo or stabilizer is applied post-relaxer to eliminate chemicals and excess moisture.
- Protective creams or base creams are essential to shield the scalp and hairline from chemicals during the application.
- Virgin relaxers should be applied 1/4 to 1/2 inch from the scalp for optimal results, as body heat helps spread the product.
Curl Patterns and Texture
- Curly hair is generally associated with an elliptical follicle.
- To achieve an s curl pattern, 75% of the curl must be removed during the service.
- A pull test is used to assess hair elasticity.
Chemical Interactions

- Extreme breakage post-relaxer can result from improper neutralization or overprocessing.
Professional Practices
- Clients should refrain from shampooing their hair for 48 hours before a sodium hydroxide relaxer service.
- The importance of consulting clients about their relaxer history is crucial in determining the appropriate service.
Curl Reformation Services
- Curl reformation involves thinning the natural pattern, typically requiring a thinner than normal parting during application.
- Chemical blowout or curl diffusion is a process that reduces curl by about 50%.
- The main ingredient in curl boosters and rearrangers is ammonium thioglycolate.
Treatment and Aftercare
- Lost moisture and protein from chemical processes can be replenished using protein or moisturizing conditioners.
- Natural oils are restored by applying conditioning treatments after relaxing.
