I did not experience hair growth, but I did notice the rate of hair loss was slowed. Additionally, the hair had more body, HOWEVER, the company SUCKS and is disreputable! At the time I purchased my Theradome, no warranty was provided. When I called about this, I was told I would not have any problems, which was not case. Several times during the year, after I first received my Theradome, I had to call them and their customer service was able to help. Then, about 13 months after I received the device, it stopped working. After many calls, the company mailed me a new battery charger. Still, my device did not work. Only then was I advised that a new warranty program had recently been established for purchasers like me, who had received no warranty. This new program required me to send Theradome a check for $100 or $150 (I can't recall the exact amount), and they would repair my unit!
I have never received such shoddy, unprofessional treatment! At about the time my Theradome died, my front-load 13 year-old Whirlpool washer died, and though my extended warranty had expired one month prior, Whirlpool sent a tech to my home, who fixed the machine and did not charge me for the repair call, only the needed replacement part.
If you are interested in laser hair therapy, go to howtoLou.com for directions on making your own device, for less than $100. Or check out other online retailers for devices similar to Theradome, for less than $200. From what I can tell, the major difference seems to be Theradome uses a hard-hat type helmet, while the others use a less-bulky type of head gear.
Bottom Line: No, I would not recommend this to a friend
