I have 2bc hair in the canopy and the underneath is stick straight as well. I have the remains of a perm from October 05 in the last 6 inches or so-I'm trying to keep myself talked out of another because I hate growing them out! I'm also pondering chopping off the permed ends, becuase I want to see how much curl I have on my own, but I'm chicken.
No answers, but plenty of sympathy! I would probably do it, myself, if my hair were reliably curly. I'm just restarting my curly journey so I hope it will come to life soon. My hair is about the same length as yours too, fwiw.
2cFii-ish with 3a moments. Always subject to change.
I'm voting for Bunny.
