This unique and revolutionary Hair Growth Inhibitor Spray from Skin Doctors has been designed to actually help discourage unwanted hair from growing back. Hair that does grow back is often finer, sparser and lighter than before with Hair Growth Inhibitor Spray from Skin Doctors, and in many cases the hair doesn’t grow back again! So that means no more tweezing, no more waxing, and no more pain. No side effects except for the slowed appearance of hair growth and softer skin. The product is easily applied and contains soothing plant and herbal extracts. There's no pain, no effort, no preparation and there's no skin irritation.
