Now if this isn't inspiration, I don't know what is! Both started with TWAs and have been growing their hair for close to 6 years. Everyone has different growth rates but if you have patience and take care of your hair, it will show off and show out for you!
The main thing that both of them employed was minimal manipulation of their hair. So take good care of your hair but leave it be and it will grow and not break as much.
