Study Notes
Relaxers Overview
- Both physical and chemical phases are crucial in the relaxing process.
- Maximum 85% of natural hair texture should be removed during relaxing.
- Common relaxers include sodium hydroxide and ammonium thioglycolate.
Types of Relaxers
- Aniline derivative is NOT a type of relaxer.
- Virgin relaxer services straighten untreated hair up to 85%.
- Retouch relaxers target only new growth to match previously relaxed hair.
Chemical Components
- Sodium hydroxide is present in stronger chemical relaxers.
- Ammonium thioglycolate serves as a chemical reducing agent, softening hair.
- Ammonium thioglycolate relaxers have a pH range of 8.5-9.5, while sodium hydroxide relaxers range from pH 11.5-14.
Service Practices
- Avoid brushing and pulling hair before chemical services to prevent scalp irritation.
- Consult client's relaxer history before service.
- An acid-balanced neutralizing shampoo is used to re-harden hair post-chemical treatment.
- Clients should refrain from shampooing 48 hours prior to a sodium hydroxide relaxer service.
Client Record and Safety
- The client record should not include legal information.
- Protective cream is essential to shield unprocessed hair during retouch services.
- Sodium hydroxide requires base cream application on the scalp to minimize irritation.
Additional Techniques
- Curl diffusion or chemical blowout reduces curl in overly curly hair.
- Sodium hydroxide relaxers are suitable for tightly curled hair.
- Mild ammonium thioglycolate relaxers are best for healthy, color-treated, fine-textured, or porous hair.
Contraindications
- Avoid applying sodium hydroxide to hair previously treated with thioglycolate relaxers.
