I'm a first timer transitioning to natural

Sherita • Smileyy Is My Name Very Goofy & Love Making Friends Looking For Bestfriends Though😂💕😘

when i was little i had the prettiest curly hair ever.. Very very thick.. so thick that my mother felt like she had to put a relaxer on it. i was 5 years old when i got this relaxer. i hated it but loved it at the same time because my hair was so smooth and silky... when i was 9 i had gotten an Ultra Sheen Supreme relaxer.. again my hair was healthy long and very thick. Now this last time of me getting the same relaxer changed my hair... i went from moisturized relaxed and very thick hair, to sahara desert dry hair.. it broke off a whole lot. no matter what or how i did my hair, it broke off in the back and became very brittle and just dead. i really need help on bringing my hair back to life. what are the first steps to getting my hair back to a healthy state???
