Hairmax laser comb users or past users

hi there

i recently bought a hairmax laser comb and started to use it around 3 weeks ago.

just searching some stuff today and noticed there is a lot of bad press about the product.

i know alot of people think its a scam etc but i want to know from people who have used it or tried it. did it work for you ? was there any difference ? did you actaully get thinner on top ?

any help would be great.

I feel like like i definitely did after 4-5 weeks so i sent it back. Why have you heard it causes thinning??
