Helpppp ! my hair has looked/been damaged all my life?

You should get you hair trimmed regularly for the dry spots. That'll make your hair grow stronger with any blockage. Take it easy on the relaxers. You can also use moisturizers so that it won't dry up. Also, make sure your shampooing and conditioning your hair in a way that it won't get damaged....like wash it thoroughly and stuff. When drying, go naturally, you shouldn't blow dry that much or use heating products that often ( not saying that you shouldn't ever use it again, but just take it easy). When brushing, don't use it to hard, especially with the plastic ones since they lead to breakage and split ends. Also a healthy diet is needed to fix damaged hair. Drink milk, plenty of protein, vitamin E, and all that good stuff. Hope this helps.
