Please help? will my daughter ever change?

Well I guess I should start from the beganing...When My daughter Kasey was 13 years old she had very pretty blonde natural hair and blue eyes and she was a cheerleader....Then the mid year of the age 13 she quite cheerleading and asked to dye her hair black...I remeber telling her No then later yes...then she started wearing chains and dark make up and got a lip ring and cutting herself...she hid the cutting from he til she was about 14 and a half...I took her to the doctor he gave her meds and sent her to a therapist. ...as time went on she got worse by the age 15-up she was pure GOTHIC and scary looking too...she was kicked out of 4 schools because of how she dressed and looked. ..now she is 23 with 2 kids...shes calmed down on her goth ways but still has Pitch black hair and dark make up and clothes...but she isnt scary looking anymore...Will she ever change or is this "phase" just who she will always be???
