I was born with thin hair, but the older I get, the more-top-of-the-head scalp I see. I won't spend thousands on a transplant, & I don't like wigs. Minoxidil had little benefit. I started using the HairMax Laser Comb on Oct. 19, 2013. I bought the 12pt laser, which is an 8min treatment 3x a week. The brochure says "there's nothing that suggests" using the comb for longer periods &/or more often boosts its benefits, so I don't bother. After 3 1/2 months of using as directed, it's working! Slowly but surely, IT IS WORKING! #answeredprayer
