How can I make my hair better?

How do I get nice hair? I'm black African and my hair is really damaged, it's breaking at the back and front and becoming thinner everyday. I keep relaxing/perming it but I think this is just making the situation worse and the same problems occur. I haven't relaxed my hair for 3 months and it's pretty bad. I also don't relax my hair often, just once in every 3-6 months. I hate my hair and I wish it would grow, not be so bushy/nappy and not break, I don't really like weave or hair extensions much and I don't want to have to do this to my hair. So does anyone have any help/suggestions? Thank you in advance.

Why not go to a hairderssers and get the full works, it always helps my hair when it is damaged :>
