What is the secret in CaffeineGRO Hair & Beard Serum Spray? As we age, our hair follicles weaken, and our hair becomes brittle. Balding or hair loss is common in both men and women, but balding is mostly common in men. Men can experience a receding hairline as early as the age of twenty-five! The CaffeineGRO Hair & Beard Serum Spray contains two powerful ingredients, namely Caffeine, and Minoxidil, which help stimulate hair follicles for regrowth and better blood circulation.
