Revita® Hair Growth Support Gummies are a dermatologist-formulated blend with medical-grade, clinically-effective ingredients for visibly thicker hair growth and fuller scalp coverage. The natural ingredients target root causes of thinning such as stress, lifestyle and nutrition, resulting in faster-growing, thicker, stronger hair. Zinc promotes protein synthesis; biotin works with zinc to convert nutrients to energy and aids in the maintenance of hair; keratin provides strength and improves hair flexibility; and iron delivers oxygen to the hair root and helps maintain hair fullness. You'll begin to see fuller, thicker, more resilient hair and hair quality (texture, shine) improvement in 2-3 months.
