I have found that the Lightsheer diode laser works better on thin (dark) hair regrowth than the alexandrites. Both do very well for the initial treatments though when the hair is coarse.
My last laser treatment was in the end of May. In the last week or so I noticed some black dots on my arms on the biceps. These were definitely new. I squeezed a few of them and they were singed hairs, they came right out without any tweezing. The hairs must have deep within the follicle in their early growth stage when they were singed and just now worked their way out. I never had that happen with the Apogee.
