You've mentioned many times how the LaserComb will shed hair in the early stages of use. Is it possible that one can start heavily shedding at a much later date as far in as maybe 20 weeks? This has happened to me. I kept using the comb and at 25 weeks have much less hair than before. We are told to evaluate our hair at 20 weeks. Well at 25 weeks and weeks later I have less hair than when beginning using the comb. Should I continue? By the way, checking with my doctor on a routine physical showed no abnormalities with any lab tests (thyroid, hormone levels, etc.) so I am perfectly healthy and normal.
