Inhibitors of 15-hydroxyprostaglandin dehydrogenase (15-PGDH), for example tetrazole, styrylpyrazole, phenylfuran, phenylthiophene, phenylpyrrazole, pyrazolecarboxamide, 2-thioacetamide and azo compounds, are useful for promoting or stimulating pigmentation of the skin and/or skin appendages and/or for preventing and/or for limiting depigmentation and/or whitening of the skin and/or skin appendages, notably for preventing and/or limiting canities.

Inhibitors of 15-hydroxyprostaglandin dehydrogenase for stimulating pigmentation of the skin or skin appendages

An O-acyl product derived from glucose which may be obtained by partial or total esterification of glucose and of vitamin F, comprising a mixture of esters, for example, monoesters, of glucose and of at least one acid chosen from linoleic acid, oleic acid, palmitic acid and stearic acid, compositions, for example, cosmetic and pharmaceutical compositions, comprising this novel derivative, and their use for improving the condition of head hair and/or other hairs, and, for example, for reducing and/or impeding the loss of head hair and/or other hairs, and/or for inducing and/or stimulating hair growth, as well as a process for preparing O-acyl derivatives mainly in position 6 of glucose, comprising preparing a mixed anhydride by reacting a carboxylic acid with a trimethylacetyl halide, followed by reacting said mixed anhydride formed with glucose.

The invention relates to a cosmetic composition containing at least one 15-hydroxy-prostaglandin dehydrogenase inhibitor and cosmetically acceptable excipients. It also relates to a method of cosmetic treatment for promoting the growth and/or preventing or delaying the loss of hair, and the use of a 15-hydroxyprostaglandin dehydrogenase inhibitor for the preparation of a composition intended for controlling hair loss and/or for promoting hair regrowth.

Cosmetic composition, method of cosmetic treatment and preparation of a composition for promoting the growth and/or preventing or delaying the loss of hair

Hair growth-/hair loss-affecting cosmetic/therapeutic compositions contain an effective amount of at least one 2-amino-4-alkylaminopyrimidine 3-oxide having the structural formula (I):

Pyrimidine 3-oxide compounds for inducing/stimulating hair growth and/or retarding hair loss
