Some devices mix true laser diodes with LEDs and count both. Lasers deliver more concentrated light to the scalp, so look at how many of the light sources are actual lasers.
Results depend on consistent use for months. A 6-minute daily session you'll actually do beats a 30-minute one you skip.
Stick to FDA-cleared devices. Many cheap unbranded caps sold online have no clearance and no published specs.
These are expensive devices. Check the warranty length and whether there's a satisfaction guarantee before you buy.
Low-level laser therapy is cleared for pattern hair loss in men and women. It works best on thinning hair that's still there, not on areas that have been bald for years.
Most people need three to six months of consistent use before they see a difference, and results fade if you stop.
Many people combine laser therapy with a ketoconazole shampoo and topical minoxidil. Talk to your doctor about what's right for you.
Clinical studies submitted for FDA clearance showed increased hair counts in people with pattern hair loss. Results vary, and they're strongest when hair is thinning rather than gone.
Plan on three to six months of consistent use. Many people take monthly photos in the same lighting to track changes.
Many people do. Check with your doctor first, especially before starting any prescription treatment.
