Do laser helmet and laser brush really work for hair regrowth?

Lasers do not work for growing hair, at least not at this stage.  I suggest you see an expert in hair loss treatments.  Best, Dr. Emer.

There is little clinical evidence to support that these laser helmet and laser brushes really do work. Some patients claim otherwise so if you want to use then it would be at your discretion also depends on the cause of your hair loss its always best to talk to a hair loss expert to see what type of hair loss you are experiencing. Thank you for the inquiry

Laser helmets/combs/brushes do more harm than good.  They do not aid in regrowth of hair and in fact will scar the dermis creating progression of hair loss.  Do not use. 

There is no scientific studies that show there is substantial hair growth from using laser. However, in my practice there are many clients who had used laser and claimed it slow down their hair loss and even got some hair growth. You can use any medical hair treatment option at your own discretion and see if it works for you. 

There is no proof that laser devices grow hair back. There is too much money in it for the doctor to be objective and patients want something to try. Try it if you like, it will not hurt youy
