I bought the HairMax Laser Comb too. I used it for around 3 months without missing a single session. Now im not one to make up stories or speak dishonestly about anything but i believe the comb contributed to the destroying of my hairline. Perhaps it was just coincidence, but id been maintaining beautifully for around 2 years on Finasteride before i started using the comb. I just wanted to try and increase some volume. I dont want to scare you off. But i think this product is useless and its very time consuming, clumsy and awkward to use. Its just very well marketed..Having said that, it has been cleared by the FDA so i dont think it will harm your hair. I actually sent mine back after around 3 months and got my money back. It could be worth a try if things are desperate, but if your hair is in reasonable shape, steer clear! If it aint broke dont fix it!
Good luck bro.
