Does Laser Hair Rejuvenation Work?

Low level laser therapy for hair does not work. I’ve offered it at my practice for FREE. I even gave it away as a study. I have not seen results. Maybe you can claim the patients didn’t use it right.The studies or papers that are out there do not show clear results. If they work, it is so minimal it’s not worth the effort or cost to justify a result that can not be seen with a naked eye for someone to say “that was worth it”.Most lasers are in the range of 650 to 670nm wavelength This is not a magic number wavelength for hair growth.650-670nm is the RED wavelength in almost ALL lasers. (red laser)The $1 WallMart laser pointer is ALSO a low power (low level) laser that emits at 650-670nmThese hair lasers are just a dome or a hat that incorporates 20 to 30 of these $1 lasers.You can make one for yourself for probably under $50.This is a GREAT marketing and business plan. (note: sarcasm)

The results of laser hair rejuvenation on hair loss are typically not impressive. While low level laser therapy is FDA approved for hair loss treatment, there are many chemical pathways involved in hair loss. This includes the role of DHT and TGF-beta which interact to stop the hair growth phase, cause cellular death and promote the miniaturization of follicles. Laser energy won’t stop this.
If you are experiencing hair loss and thinning on the crown, you’ll achieve better long term satisfaction from a hair transplant.  With the use of body hair grafts, it is possible to expand your donor supply to obtain more ideal forms of coverage if head hair alone is not sufficient.

Low level laser therapy in combination with other hair loss treatments helps. It works by improving blood circulation to the base of the hair follicles. I've had a patient on low level laser therapy for three months with very good results. But in a lot of cases in medicine every treatment does not work for every person.
