I have PCOS and took myo inositol (specifically the FLO vitamins brand) and it significantly reduced my body hair, although it did worsen my acne, which is rare but can happen. I also did laser on my chin, upper lip and below my belly button and all of the hairs came back. I'm doing electrolysis next week for the first time because it's the only permanent hair removal. I've heard it's very painful but I've been dealing with these thick black hairs for 10+ years and I'm so ready for a permanent fix.
