No to the friction method! I have used every type of hair removal method, friction being one of them; sad to say that this method only gave me terrible ingrown hair, yes it was smooth at first but then the ingrown hair appeared, like nothing I have ever tried. It could work for those that have thinner BODY hair, I would not recommend it for use on the face. I have very thick body hair but around my knees the hair was thinner, now I barely feel any hair around my knees, was it the friction method? (I used a pumice stone) My guess is, it could of been. Do I recommend it though? No, I do not; the ingrown hair I got afterwards were so bad and left me with with some scars afterwards that I had to stop using it completely. You are better of with something that won't damage your skin.
