At this point I don't see much difference in my hair. Small differences may exist, but nothing that would be noticed by those not analyzing the hair. A person following the FDA recommended twice weekly usage would just now be to 26 treatments. Per the Theradome website:
After 26 treatments (twenty minutes per treatment)
Thicker and longer hair.
Reduced scalp itching and inflammation.
Enhanced curl retention for curly hair.
...none of those items would be easy to demonstrate in a photo. My guess is these next 3 months will be the most telling as to whether or not the Theradome works as advertised.
