You can't repair damage but you can prevent it.
First, get regular trims, every month and a half to two months.
I also use a repair serum after I shower.
When I blowdry my hair, I do not use a brush- combing your wet hair can pull it and break it
I always use a blowdry/straightening/curling spray to protect it from heat.
Your hair will always continue to grow- it has to. I do suggest to stop dying it if you can, and leave the dying to the professionals who can use things that won't kill your hair. Keeping away from color extremes helps too. Don't go from black, to bleach blond, to neon pink or something.
