It's a female donator hairstyle, under hairstyles 3. It tells me: "Excuse me. Looks like we have a little problem changing your hair. Please, come back in a moment." I've tried different colours, it won't allow me to change to that hairstyle And yup, I do have a coupon in my inventory
It's actually a Male hairstyle and that's why you can't buy it, and it have to be moved to the Male section.
