EXO HAIR™ Red Light LED Hair Brush

Low-level light therapy has a reasonable evidence base in pattern hair loss — better than most things sold for hair, and weaker than the prescription options. It appears to work by increasing follicle cellular activity and scalp circulation. What that means practically: it is a legitimate adjunct, most useful for early-to-moderate thinning, and it works best alongside a topical rather than instead of one. It will not restore a follicle that is gone. If your thinning is advancing quickly or patchy, get it looked at rather than treating it with a brush.

Follow the device timer — it is cordless with an automatic cut-off for a reason. Several sessions a week, consistently, on a clean dry scalp, working over the areas you are watching. Hair cycles slowly: three months is the earliest anything is visible and six is a fair judgement. Take a photo of your part line in the same light today, because month-to-month change is almost impossible to see without one.

Possibly, and that is a conversation worth having before you spend $215. The prescription options have the strongest evidence in pattern hair loss, and for someone with active, progressing loss they are usually where a physician starts. Light therapy and topical serums layer on top of that well — they are adjuncts, not replacements. Also worth ruling out the treatable non-genetic causes first: thyroid, iron, and post-surgical or post-illness shedding all mimic pattern loss and all resolve differently.
