I know there are lot on here who think laser therapy is sh*t, but for me personally, it has been working. Not for regrowth, but for maintaining what I have. I have a 250 diode helmet. Not one of those crappy 10 diode combs (do not buy one!
In my opinion, lasers are more for scalp health, blood flow and helping to hang on to what you have. Not really for mass amounts of regrowth.
So many people who have never tried it, or tried it for extended periods of time, always seem to sh*t on it.
I have been using mine for about 4 yrs now, and my hair still has good density. Absolutely no scalp itch or irritation. No finasteride, or minoxidil. I'm trying to steer clear of that sh*t.
Laser is a long term thing, like Fina and minoxidil. You can't expect miracles after only using it for a few months to a year.
My scalp has never felt better and my hair is thicker.
But like most non-pharma, big 3 bullshit, it's gonna get frowned upon.
To each his own, I guess.
