During my eval the electrologist strongly suggested I do a hybrid approach with laser for the black hairs and him for the gray hairs. He says he's had other long-term clients with really good results from the new lasers--he tends to stay in touch with the girls because he does the pre-bottom surgery electrolysis for them. I was impressed that he'd give up a lot of income by telling me this, especially since he didn't direct me to a specific laser center with the possibility of a kickback arrangement. So I'm doing the laser with electro visits in between for the all too many gray hairs. The nice thing is instant gratification and the gray hairs don't require color correction and aren't very visible when I grow them out for the electro sessions.

Having now done a lot more research, but needing qualified guidance, I am now suspecting that I will need a hybrid approach too, like JulieM has identified...

I am fairly much at a mature age  and have much grey, light brown and some slight smattering of dark hairs on my face, my arms are mostly light brown, white and a slight smattering of dark hairs, same with upper legs and butt... Lower legs are almost hair free and my body is hair free (oh so much a big thankyou to HRT)... anyway back to the point... I have fair skin which has also led to some sun damage and minor skin cancers on my upper face... despite overall good skin condition (e.g. Softness and radiance).

I have gotten a lot of good insight out of this thread and has been very motivating for me

Thanks
