A few weeks ago, I wrote about the Hairmax Laser Comb, which purports to grow thicker hair. Now Bliss Spa is selling a laser for use on facial skin, the Beurer Softlaser Healer. The low-level laser is supposed to stimulate collagen production which helps with wrinkles, scars, and acne. Bliss says this is accomplished through the "right UV rays". I don't know what that means, I thought all UV rays were bad for skin, but some people at the YTF! Beauty Report Forum have reported good results, especially with acne. The Beurer Laser is $219, while the Hairmax is $700. I would think you could run the Beurer across your thinning pate as well, but maybe the "right UV rays" are the kind that kill hair follicles.
The efficacy of lasers has long been debated and the latest study found that lasers had little effect on acne. One session with a big gun like the Smoothbeam, which is FDA approved for acne and scars costs about $400, so maybe now is the time to embrace the DIY spirit.
