New Laser Hair Removal for Blonde and Gray Hair?

Most radio frequency devices or IPL will try to tell you the can perform permanent hair removal. That is not the case. There has been a recent article about meladine being used to stain the hair to be treated and thus allowing true laser hair removal to be performed.
I would ask your local dermatologist or plastic surgeon that provides laser hair removal if they have heard of this product and use it.

Although it would be rare for the hair to grow darker and denser, this has been reported.  You must know that the treatment for gray and blond hair is very difficult and may not be effective.
