I have black diffuse thinning NW3A hair, having been on treatment for a while I've stabilised my hair loss but it is still extremely thin. A lot of the density that I have, the hair has lost pigmentation, black hair becoming brown or generally not as deep black. This might also have to do with summer sun exposure as well. Anyway. I was thinking if I was able to darken or dye my hair with some natural products, does anyone have recommendations? If I was able to get colour back to the hair that I have that has become lighter, it would make my hair look much thicker.
