Hi Dr. Rassman & Staff. Great blog.
Anyway, here’s my question. On my morning drive into downtown Chicago, I invariably hear radio commercials for laser treatment to REMOVE “unwanted” hair. Yet, I also see promo’s for laser treatments to GROW hair. Well which is it … do lasers GROW or REMOVE hair?
The lasers which claim hair growth are a low level laser energy dosage that do not penetrate the skin… nor do they grow hair, in my opinion.
The lasers for hair removal are high energy lasers which focus the power to a very small area (the hairy area that you’d like de-haired) in bursts to be safe. They will penetrate the skin to get to the root of the hair follicle.
Both lasers work at different light frequencies.
