Revivogen is a natural hair loss treatment that works. Scientific studies have shown the natural ingredients in Revivogen are both individually and synergistically effective in helping reverse thinning hair and genetic hair loss in men and women. Hair loss is triggered by the production of dihydrotestosterone (DHT) within the hair follicles. Ultimately, DHT strangles the hair growth in the areas it impacts, causing hair loss and thinning hair. Revivogen is formulated to prevent DHT's production, thus interrupting the hair loss process.
