Serious info, questions only answered by doctors.
The LaserComb is snake oil and doesn't work. The laser's class has been FDA approved that it won't hurt you... but it won't help you either.
All the "all natural" products out there promising to fix your hair loss or block DHT are BS, they simply give you a placebo effect. That's not to say some can't help. Selenium, Zinc, Fish Oil, eating better and taking a good multivitamin can all be helpful, but are not treatments.
Propecia (or Finasteride) and Rogaine are the only FDA approved treatments that do show results. Your mileage may vary, but they've only been shown to work on balding from the back and not from Male Pattern Baldness from the front... however it's better than nothing and some results have been shown.
I've used both, plus fish oil and vitamins for a few years and my hairloss stopped. I began losing at 21, but since then I haven't lost anything. I started using just Rogaine and then switched to Propecia for less mess. Maybe it was just general thinning (that happens too), and I don't actual need the meds, but why rock the boat now?
Another thing that can help is Nizoral 2% shampoo. It's a prescription anti-fungal shampoo, but some research suggests that it can help to use it about twice a week.
