Got some results though skeptical. Takes a while, min 8 weeks, so be ready to do some shaving biweekly for a bit! Takes a while for legs, I’ve resorted to doing only “bits and pits”!
Doesn’t work significantly on fine light hair, makes darker coarser hair finer and lighter or helps it to slow/stop growing with intentional repetition.
Might be worth it to wax then flash!
