As far as I know electrolysis is permament, but when I enquired about it, I was told that the beautician would only remove fair hairs if I dyed them for some weeks before the treatment as othewise they would be too difficult to see!
This put me off, and up til now I remove the hairs on my chin using a pair of eyebrow tweezers. I funk doing the same on my upper lip, where it hurts more, so cut back my moustache with a pair of nail-scissors.
I did once use Veet for facial hair and found it quite good, although you have to use it a day or so before going anywhere, as it left me with a angry red upper lip, or whatever the bit between your lip and nose is called.
Now they don't seem to make it any more, and the one from another firm I tried removed the skin but left the hairs! And yes, I had followed the instructions carefully.
I can't see to trim my eyebrows any longer, and they are getting bigger and bushier by the minute, although the hair on my head, armpits and pubic area is thining - those on my legs and arms are still flourishing. I shave them, but don't advise shaving one's upper lip or chin, as the new hairs growing in look very black - five o' clock shadow to rival my black-haired father's.
