How effective is low-level laser therapy (LLLT) in treating hair loss?

ANSWER

Most people like home treatments. You can do them whenever you want (for about 15 minutes, three times a week), and they cost less than doctor visits.

When LLLT works, you should see thicker, fuller hair in about 6 months -- the same amount of time other treatments take. But LLLT won't help if you're completely bald.

We still need more research to figure out the best way to use it and how long the effects last.
