My hair used to be beautiful as seen here...

And it was like that til I was about 15... then came all the straightening and products cause curly hair wasn’t “in” and now my hair looks like this..

It’s dried out... way done with being dyed and just blah... I know I’ll never get the hair I had back... but any idea on how to let my hair grow and try to naturally encourage my curls to come back after a little over 5 years of bleach, dye, products, and straightening it?
