Skeptics (among them, Dr. Wesley) are starting to come around after a 2014 randomized double-blind study published in the American Journal of Clinical Dermatology found a “statistically significant” difference in hair density for women who used a laser comb compared with those who used a sham device. (“Comb” is something of a misnomer. The device looks like a hairbrush crossed with a cordless phone; it is glided back and forth across the scalp, roughly a half-inch at a time, usually about 15 minutes three times a week.)
My question would be, I am on the right track or is it overkill? I’ve read that using too much stuff (solutions or shampoo) maybe detrimental to keeping your hair. I know 6 month might be a little time but I still don’t see noticeable results and I’m afraid I might be doing something wrong or worsening the situation, even though I don’t have worse hair loss than before.

The other main hair-loss treatment that was recommended by all four dermatologists I interviewed is finasteride, often called by its brand name Propecia. This FDA-approved medication is only available with a prescription, but these days, it’s found as a generic and ordered online after a virtual consultation, through start-ups like Hims, Keeps, and Lemonaid.
