Hair growth: Despite what you may hear from companies or advertisements, nothing in a shampoo really helps hair growth. Hair growth is controlled more from inside. Check your iron and possibly thyroid levels--more likely to be playing a role. Topical Minoxidil can help some people. Unfortunately, no quick fix!
