Study Notes
Relaxer Theory Overview
- Avoid removing more than 85% of hair's natural texture to maintain its health and integrity.
- Early relaxer products had a high pH level of 14, indicating significant alkalinity which can damage hair.
Historical Context
- The temporary hair relaxing method was invented by Madam C.J. Walker in the early 1900s, marking a significant development in hair care.
Importance of Phases
- Both the physical and chemical phases of hair relaxing are crucial and should be treated with equal importance during services.
Key Ingredients
- Sodium hydroxide, a strong relaxer ingredient, necessitates the application of a base cream on the scalp to prevent irritation.
Types of Relaxer Services
- Four basic relaxer services include:
- Curl diffusion: Loosens tightly curled hair patterns by up to 50%, also known as a chemical blowout.
- Virgin relaxer: Applied to natural, untreated hair, capable of straightening up to 85%.
- Retouch relaxer: Targets only the new growth to match previously relaxed hair.
- Zonal relaxer: Performed in selected areas such as the nape or hairline for targeted texture adjustments.
Common Products
- The two most widely used relaxer products in the industry are sodium hydroxide and ammonium thioglycolate.
Physical Phase Steps
- The physical phase of a relaxer service comprises four critical steps:
- Smoothing or combing the hair for even distribution.
- Timing and testing to ensure proper processing.
- Rinsing and blotting the hair to remove excess product.
- Neutralizing to restore the hair's pH and prevent further damage.
