can ayone comment on the effectiveness of the laser hair comb

[joe from staten island]

i am considering purchasing a laser comb. as you know my hair transplants have stayed the same length of 1/2 to 1and1/2 inches for over twenty five years. believe me my grafts simply do not grow longer. has anyone used the laser comb and can it increase blood circulation and vascularization in the scalp. i have been told my many prominent hair transplant physcians that due to all of my prior surgeries that i have a circulation problem in my scalp.any advice or comments that anyone has to offer on the effectiveness of the laser comb would be greatly appreciated. thank you joe
