My daughter has PCOS and is taking YASMIN. Yes it helps with the Acne and the hair loss. Yasmin has an anti-androgen blocker in it. It is the only pill on the market to do this. It was too strong for my daughter. Without the pill she had hair loss. With the pill she had hair loss. She cuts the pill in half and it is perfect. She has stopped the hair loss. She isn't taking the pill to prevent pregnancy so we tried the pill cutter. It worked great.
I would never let a girl take propecia. It isn't good for her.
