I’ve been using the Hairo cap every day since receiving it and am already noticing a difference with tiny new hair growth framing my face.
It’s incredibly convenient to use for 10 minutes every day. Anyone concerned with thinning hair should seriously be considering this purchase.

I had ordered Hairo LLLT Hair Growth Cap about a year ago for my husband. Generally, I don’t write testimonials on amazon. But in this case, I am impressed by the results, and I have to say that I see a difference and some new, short hairs are sticking out of his crown and forehead. This Hair Growth Cap is very easy to use by pressing just one button on the battery, which is mounted at the back. There are no hanging cables, no need to connect to a power point during usage – it’s a totally portable device. Also, cap size can be adjusted by tightening or loosening the velcro straps at the back of the cap. In my view Hairo Cap is a very good balance between great quality and competitive price. Would highly recommend for people, who don’t want to splurge on other high-priced hair growth devices.
