What are your tips and tricks to get healthier hair, especially when it's damaged?

Hi all! My hair has gotten quite damaged from lots of bleaching and I'd love any and all recommendations please on how to not just repair my hair, but also how to get it as healthy as possible to try to get it to finally grow more.

I know to try to limit heat on it as much as possible and to do a hair mask like once a week but what else would you recommend? Any specific brands too for deep conditioning?

Some tips I've seen and going to try: -sleeping in a satin hair bonnet -letting my hair dry 80-90% on its own before I use a hair dryer -weekly deep conditioner masks -biotin supplements

Thank you in advance for any and all tips!
