Things They Should Invent: hair removal methods that change the colour of regrown hair

As we all know, methods that remove hair from the root may reduce hair regrowth, but results may vary. However, as we also know, existing hair removal methods can only remove hairs that are currently sticking out of the skin. Hairs that are dormant are not removed. So you go through your favourite hair removal method, and then a few days later there are hairs growing back in that area. Are they the same hairs regrowing, or are they previously dormant hairs waking up? We have no way of knowing, so it's hard to tell how well the hair removal method is actually working.

What I want is a system that causes any hair that was once removed to absolutely, infallibly grow back looking noticeably different. For example, where my body hair is black, the regrown hair would all be blonde. Then I could tell if it's actually working.
