xin chào guys, is it WEIRD if my FC has hair?

Her names Invader Bri. Shes also a smart princess! X3 In her bio, one ngày she was conducting a experiment called "How Hair Grows" (Weird, right? XD) And she accidentaly fell and the chemichals came out of her hands, went into mid-air, then fell on her bald head. XD And giờ later, she had long, black hair. AND I DONT LIKE HOW THE HEADS ARE SHAPED! xD So the point of this is: Is it ok hoặc weird for your FC's to have hair?
