Hi @Beginner. My slightly wavy hair came back very curly and remained that way until I lost it all again four years later with another chemo treatment. Nearly three years later and even the curly girl hairdresser says it is VERY curly. I just do the curly girl routine and live with it. Not overly happy with it but it is only hair, even though it has changed my whole look. My hair is a bit darker now and I am hesitant to do anything about that. Dark curly hair is better than risking no hair at all. Look online for curly girl hair techniques to make the most of it. Using the curly hair techniques will also moisturise your hair.
Thank you for that information, I will look into that technique :)
