Laser Treatments for Hair Loss

It seems there has been advancements in hair laser technologies for hair loss and I haven't kept up.

I have a handheld Laser, a custom build laser helmet by OverMachoGrande, had owned a Theradome Laser Helmet that I had returned(since it was faulty).

Having these in the house, I ignored the laser treatments offered in the clinics.

But now I am seeing there are CO2 Laser treatments. Fractional laser treatments and also Thulium laser treatments.

It seems these are different than the household ones I mentioned. Particularly have read great things about Thulium. Wondering what your thoughts on these and can they actually help regrow hair.

I have found two clinics close to where I live.

One of them has a Thulium Laser. They called is LaseD.

Another one is an Erbium:YAG laser.

It looks like they are both very good treatments for hair regrowth.

I am currently trying to find out if one is better than the other. I am comparing in terms of effectiveness, pain but also side effects. Some lasers are said to make a person lose volume which something I definitely don't want. But from what I have read so far Thulium Laser or Erbium:YAG lasers do not cause volume loss. If anybody knows otherwise please let me know. I am hoping to do this in the coming weeks.
