My poor dil is only 23 and has really excessive facial hair. It's dark and fairly long and ink her lips chin and cheeks. She has seen the dr who tested for pcos which was negative but that's it and it wasn't pursued. I feel so sorry for her, she is training to be a hairdresser and so appearance is important to her. I'm going to go to the gp with her and ask for a referral to maybe a dermatologist or someone who could help, but am I wasting my time? I told her I would post on here to see if anyone has any experience of this.
I think it is sometimes available but your Dd would need a definite diagnosis of a medical condition. I certainly think you should go back to the Gp with her and ask for some more thorough tests - pCOS is only one cause of facial hair, I would guess it is likely to be some other hormonal condition, so I think the specialist you want would be an endocrinologist - definitely push for a referral because even if your DD can't get the lazer treatment I should think there might be drug treatments or something which might help.
