Answer the question about text:

I had black and purple hair for 5 + years . Before that , it was a plethora of other colors , such as completely bright blue and hot pink . Well ... I decided I want to grow my hair long and keep it in better shape after SO much abuse . I tried going brown , but it did n't want to stay a nice rich auburn color ....

Why does experiencing abuse and overcoming it cause the speaker to want to take better care of themselves ?
Their self esteem is improving , so they are updating their appearance to match
