Is hair laser comp efficacious for hair regrowth, even after you stop using it?

Yesterday I saw this advertisement of hair laser comb, and it was actually somewhat intriguing to me. I have recently noticed thin hair in my crown, and this has made me really anxious. As per the advertisement, it promises hair regrowth, and it is actually something, which I want badly. Is there someone amongst you guys, who has ever used a hair laser comb for hair regrowth? Did you find it useful? In addition, most importantly, is it efficacious even after you stop using it? Please help with appropriate suggestion!
