Ducray Tonifying Gel 30ml is a stimulating gel designed to combat hair loss that occurs in patches. Enriched with methyl nicotinate, a vasodilating agent that improves microcirculation on the scalp, and a variety of soothing natural essences such as verbena and cedar, this gel nourishes the hair bulb and stimulates hair development. The scalp is strengthened, balanced, and revitalized, while microcirculation improves by 32% in the first 15 minutes after application, according to clinical trials.
