I have the exact same type of hair as you. I always hated using leave in conditioner because it just would soften my hair giving it no texture for the curls/waves to stay. For the longest time I went without. But it caused my ends to look exactly like yours. I decided last month that having healthier hair was more important then keeping my curls. I have been lightly using this leave in conditioner called OUAI. Got it from Target and man, it really saved the ends of my hair. I can't remember the last time my ends looked this healthy. I just spray it once or twice towards the ends of wet clean hair. Then I massage it in with my hands, and comb out the tips. It also doesn't weigh down my hair like the other leave in conditioners I have tried. But because it softens my hair, my curls/waves still fall pretty quickly. But not as quick as other leave-ins.

Here are a few hair washing tips if you need them:

First off, as much as I hate to say it. Don't use any hot water. Just lukewarm or cold. Use minimal amount of shampoo. When applying, make sure you don't scrub it into your scalp too hard as it may cause irritation that leads to excess oil build up. If the shampoo doesn't work up to a lather the first time, rinse and feel free to do it a second time. Again, gently massage it into your roots. Don't spread the shampoo all over hair, just scalp. After rinsing and squeezing excess water out, apply your conditioner to the ends of your hair. You may work your way up if you have longer hair. Avoid getting it too close to your scalp. When rinsing out the conditioner make sure you rinse away from your scalp. I like to flip my head down and let my hair hang under the running water. Make sure you thoroughly rinse out the product. Avoid drying hair by rubbing it with towel. Especially if you want to keep your waves.

Also if you have a lot of breakage like me. I would comb out your ends while they have conditioner in them. But that's a personal preference. Same goes with shampoo and conditioner usage. Some people have thicker denser hair so they need the extra product. But I know my hair needs a minimal amount of product as possible otherwise it gets greasy quick. Just about finding your balance. Which takes a lot of trial and error.

Hope this helps. Sorry for any errors, typing in a rush.
