has it is drawbacks but seems to help some regrowth [SEP] this does seem to encourage eyebrow growth though no miracles it takes repeated use it is easy to get oil on sheets or anything that comes in contact with your eyebrows i have had a few of these two things i cannot stress enough when the little rubber washer falls down around the applicator brush do not throw it away push the rubber ring back because without it the bottle leaks oil whenever it is not straight up and down also the bottle is made of glass after having one roll off the vanity and break on the bathroom floor flinging oil everywhere i replaced it and the first thing i did was create a bubble wrap holder cardboard on the bottom to allow it to stand up and bubble wrap on the sides to prevent it from happening again it is a hassle and the results are not magic but with consistent use it does appear to help bald patches in eyebrows grow new growth
