I've a male who has just started using 'just for men' hair coloring for beards. First few times I used it I had no problems , but now am experiencing a painful, itchy rash and flaking skin. I really liked the product before these side effects were experienced. Is there any way to reduce or eliminate the side effects without giving up use of the product ? if not, are there other products which work well for beads which might have less severe side effects?
