I don’t think any of the spas or strip mall type places could answer those questions. Maybe if you went to a laser medical center that only allows MDs to perform the consult and procedure could you get answers to such questions. And only then with regards to that specific clinic and laser. Results vary from person to person, study to study, laser to laser. Also no studies track longer than 18 months to 2 years so forget any clinical evidence of long term results, just anecdotal.
The reason I feel wronged is that I was promised “permanent hair removal” (in writing) and also told I was an “ideal candidate.” It was explained to me that the only hairs that survived each treatment were dormant ones. Supposedly after 3-6 treatments 6 weeks apart, all dormant hairs have time to grow out and have been targeted.
However when I started complaining after 8 treatments I was told a different story. ALC said patchiness is a known side effect, blah, blah, and tried selling me some microderm and IPL treatments?! I did a few more treatments on a more powerful laser but still poor results. ALC never allowed me to see their MD either.
