How to get my hair to grow

Julie • Braxston Asher 3/9/2020💙💙

I have always had long hair but when i has my cousins fiancé who has her beauticians license bleach my hair to get my blonde back she killed my hair. What should I do help my hair be healthy and grow long again? Any help of advice is greatly appreciated. Note to self even if you want to save money go to a more professional to get your hair done and not a family member.
