Q: I am interested in trying home laser therapy for my androgenic alopecia? Which handheld laser device do you recommend?
A: There are several handheld lasers currently marketed as a home use treatments for androgenic alopecia. To my knowledge there has never been a clinical study comparing different laser devices. Most of the devices use diodes to emit a narrow band red light. This wavelength of light is actually similar to those that are used in hair removal lasers, except they are at a much lower intensity. The theory is that high intensity laser damage hair follicles causing hair loss, but low level laser energy can have a bio-stimulation effect and actually induce hair growth.
If you would like to try laser therapy for hair loss, I suggest using a “HairMax” brand laser comb. This is the only device that is FDA approved. They sell a few different “strengths” of lasers for different costs. They have not shown any clinical evidence supporting one laser comb versus another. The more expensive ones have more diode lights so it would be reasonable to conclude that they are “stronger” and require less frequent use. I have patients who have used the “mid tier” laser comb, the Premium Lux 9 successfully, so that is the one I recommend to other patients.
In what might be another illuminating discovery on the inner-workings of hair growth, Yale University scientists have discovered that cells from the fat layer in the skin of mice contribute to the stimulation of hair follicles.
