Does HSR work on grey hair?

I have been working on this for a long time, and while we were able to stimulate the melanocytes in the basal membrane of the epidermis, it seems very difficult to get melanosomes past the inner and outer root sheath. I have tried at least 10 different molecules and combinations, but to date it has been impossible to restore grey hair to its natural colour.

What is positive, however, is that the hair colour does improve because the hairs become thicker. This is due to the use of shampoo, conditioner, spray and lotions. These all have an effect that causes the hair to absorb more moisture and become thicker. This is because grey hairs also become thinner, so this is actually very good for the health of the hair. The hair will also return to a slightly more natural colour.
