While the REVIAN RED system is indicated to treat pattern hair loss it may not work for everyone. Pre-clinical and clinical research has shown that red light therapy and specifically nitric oxide release helps reduce inflammation, increases blood flow , and “re-activates” the scalp helping hair follicles renew. The challenge some people face is that the hair follicles may be past the point where light therapy can re-activate them. REVIAN seems to produce the best, most noticeable, results with users who are thinning in the front or top. Users who are completely bald on top may see a reduction in hair loss and some hair growth but I cannot promise you that your hair would come back with reasonable thickness.
