Study Notes
Perm Products and Essentials
- Permanent hair change from straight to curly requires breaking disulfide bonds.
- Alkaline perms have a pH range of 8.0-9.5.
- Heat is commonly used in acid perms alongside tension and waving lotion.
- Alkaline perms create a strong curl pattern.
- The perm rod determines both the size and shape of the new curl texture.
- Two types of perms exist: alkaline (cold) and acid (heat).
- Alkaline perms yield a stronger curl than acid counterparts.
- Main ingredients in alkaline perms include thioglycolic acid or derivatives and ammonium hydroxide.
- Ammonium hydroxide in perms shortens processing time.
- For alkaline perms, hair should be wrapped without tension to minimize breakage.
- Acid perms require hair to be wrapped around the rod with tension.
- The pH of acid perms is between 6.9-7.2.
- Acid perms require heat to process effectively.
- Ideal candidates for acid perms include fine, damaged, or bleached hair which requires extra caution.
- Acid perms create a softer, more natural curl.
- Alkaline perms process faster than other types.
- An exothermic perm generates heat through a chemical reaction and is described as self-heating and self-timing.
- Low/no thio perms are recommended for clients potentially allergic to thioglycolic acid.
- The reducing agent in a low/no thio perm is cysteine hydrochloride.
- A digital perm, also known as a heat perm, hot perm, or ionic perm, employs heated rods and perm solution for thermal reconditioning.
- A digital perm produces soft waves and curls, appearing more defined when dry and looser when wet.
- Neutralizers primarily contain hydrogen peroxide, sodium perborate, or sodium bromate.
- The pH level of a neutralizer typically ranges between 2.5-7, varying by type.
- Barrier cream protects the client's skin at the hairline before applying chemicals; Aveda uses an anti-humectant type.
- Air oxidation facilitates hair neutralization in overnight perms through exposure to air.
- Essential tools for perming include applicator bottles, perm rods, styling combs, and tail combs.
