Another recent low-carber with PCOS here! I had to regularly shave my chin hair twice a day. I would get five o'clock shadow! Within a week of starting Atkins induction, my hair growth decreased. I am now a month into low-carb dieting and still have to shave once per day, but I certainly have enjoyed this benefit of the diet! I had electrolosis on my upper lip as a teenager and it has been successful for many years. I am thinking of now doing electrolosis on my chin hairs.
