Can I continue to use hair dye while undergoing laser light therapy with the Capillus cap?Updated 2 years ago

Yes you can. Using hair dye will not affect the efficacy of the treatment with your Capillus laser therapy device for hair regrowth.  Some users have even reported that their hair is regrowing in their natural color.* 

* It is unclear what factors may cause hair to regrow in its natural pigmented color. There is no research to date to explain this reported phenomenon.
