Does the Revage 670 Work? Will It Really Make Thinning Hair Grow More?

Lasers do not work and even if it does it would not make a cosmetic difference.  Think about it this way:Revage 670 laser emits a red color laser at a frequency of 670 nmLaser pointer pen you buy from WallMart for $1 also emits a red color at 670 nm(nothing special about 670nm - it is red)

It should not cause any harm trying it out. I do not have much confidence in the laser hair loss treatment devices as the results are usually very minimal, if any at all.

I was very apprehensive about laser technology when it first came out. We tried different lasers and could never get them to produce any results. All that changed when we were introduced to a device called Luce. They are very hard to come by, but if you can find a MD in your area that has one, you should let them take a look at your condition.

I am sure there are other devices out there that claim to have more power, however more power might not make a device better. Get more than 1 opinion as always. 

Good luck with your research!
