Hair dyeing

So I'm planning to dye my hair but I'm super scared bc I don't wanna damage my hair... I have light brown, thin, frizzy, curly hair and I'm planning to dye my hair red to get that dark red color yk?? I initially wanted black or dark brown hair but I thought since I have light colored hair I could go for red.. I also planned to go dark brown or black after dark red. What are your tips to take care of dyed hair and prevent damage?
