Abstract
The invention concerns a method for straightening keratinous fibers including: (i) a step of applying on the keratinous fibers a hair straightening composition containing at least one polyhydroxylated aromatic compound, (ii) a step of increasing the temperature of the keratinous fibers, using heating means, to a temperature ranging between 110 and 250° C.

1-11. (canceled)
A process for relaxing keratin fibers, comprising:
- applying to the keratin fibers a hair-relaxing composition comprising at least one polyhydroxylated aromatic compound, wherein the pH of said hair relaxing composition is less than or equal to 9, and
- heating the keratin fibers to a temperature ranging from 110° C. to 250° C., wherein the polyhydroxylated aromatic compound is not chosen from:
- 4,5-diamino-2,6-dihydroxypyrimidine,
- 2,4-dihydroxypyrimidine-5-carboxylic acid,
- 2,4-dihydroxy-6-methylpyrimidine,
- dihydroxyorotic acid, or
- 2,4,5-trihydroxypyrimidine.
