I don't know if this will work for your friend. I think what she has is a medical condition.





My hair seemed like it was the same length forever. I started noticing a difference when I started using Garnier Fructis Length %26amp; Strength shampoo %26amp; conditioner. There is such a noticeable difference.





It heals any damage to the hair from root to tip %26amp; from the inside of the hair as well as the outside %26amp; it strengthens the hair X5. Garnier Fructis has many other useful products.
