What is "menthogen"

Menthogen is a topically applied scalp stimulant which is claimed by its manufacturers to treat itchiness and irritation of the scalp as well as combating certain types of alopecia. Since its development (see history below) Menthogen has been further developed in the UK by a team of trichologists.

Menthogen's scalp cooling effect occurs due to the presence of menthol and alcohol within the formula. Other ingredients are claimed to counteract the effects of androgens said to contribute to both male and female pattern hair loss.
