[spanky (aka Lola)]

AbiDrew is right. I have straight blond/light brown hair and used a Tria for about 4 months to no effect whatsoever. From my reading, I think the same would be true for grey or white hair.

For the last couple of months, I have been using a Braun SilkE epilator, but still do not know if it will have any permanent impact. I have had no bumps or ingrown hairs from this.

I have also tried tweezing out hairs, trying to pull out the roots. This seems to have cause more bumps/ingrown hairs. I believe waxing would cause the same reaction. Tweezing is also ridiculously time consuming, and I have largely given it up although I suspect it would be the most effective method of permanently reducing hair growth and thickness.
