Abstract

PROBLEM TO BE SOLVED: To obtain a hair growth-inhibiting agent containing a specific phthalazinone compound as an active ingredient, capable of effectively inhibiting the growth of hair to reduce the number of hair-removing treatments, and excellent in safety over a long period. SOLUTION: This hair growth-inhibiting agent contains a phthalazinone compound of formula I (R<1> is a 1-4C alkyl; R<2> is a hydroxyalkyl, an alkenyl, phenyl) or a benzoxazinone compound of formula II as an active ingredient. The active ingredient of the hair growth-inhibiting agent is preferably added to a cosmetic in an amount of 0.001-3wt.%.

The back hair of 20 9-day-old C3H / HeNCrj mice per group was shaved using an electric clipper and an electric shaver over 2 × 4 cm 2 without damaging the skin. Then, from the next day, the sample was applied to the shaved site once a day in 20 μl portions for 4 weeks. The group to which only the solvent was applied was set as a control group. Twenty-three days later, in order to observe the hair regeneration, the shaved area was photographed at a fixed magnification, and the ratio of the regenerated hair area (regenerated hair area / shaved area) was compared with the control group using an image analyzer.
