I HAVE BEEN BLEACHING/COLORING & FLAT IRONING MY HAIR FOR THE PAST FEW YEARS. I AM TRYING TO GET MY HAIR HEALTHY AND GROWING. MY HAIR GROWS BUT JUST BREAKS OFF. I DONT KNOW WHERE TO START, PLEASE HELP!
I'd say start by stopping the bleaching and flat ironing. The hair that's be subjected to that damage may be pretty far gone. If you stop those practices, though, your new growth hair should be happy and healthy.
You can try to restore some health by doing weekly deep treatments.
You probably should get a good haircut to get rid of the damaged part.
