Natural hair is manageable, and your natural hair can be manageable: you just have to be willing to work with your hair and not against your hair. That is the key. Natural hair and straight or permed hair act completely different and should be treated completed different.
One habit that I think a lot of us do not understand right away if we are use of wearing our hair straight is that natural afro textured hair is tangled hair. Once again, natural afro textured hair is tangled hair. Don't expect to be able to run a comb through your hair on one pass. That is probably not going to happen, and there is nothing wrong with that. Instead, try to start at the tips of your hair, and comb up towards the roots. If you hit a knot, stop combing. Take your fingers and gently try to wiggle any shed hair from that knot starting as close to the bottom of the knot as you can get. Pulling from the top of the knot often makes the knot even tighter than it was before.
Something else to keep in mind is that natural hair does not need to be combed daily. Many of us only detangle 4 times a month or even less than that. I usually detangle my hair once a month or at the most, twice a month. And when you do comb your hair, remember that it isn't for the same purposes that you would do if your hair was straight. The main purpose should be to remove shed hair that may cause tangling and knots. You want to remove shed hair on a regular basis so that this will not happen. Like I said, every 1-3 weeks should be enough but you have to listen to your hair.
If you are using combs with fine teeth, try using wide tooth combs or even better, use your fingers for combing. Finger combing is one of the best ways to detangle your natural hair in my opinion. Your fingers can feel what your comb cannot. If you feel a knot, you are less likely to rip through it on accident as you might would with a comb. It also forces you to be more gentle with your hair. And being more gentle with your hair helps you to keep your hair as healthy as possible.
You also have to be willing to be patient. Your regimen is not going to form over night. I have been natural for almost 5 years now and I am still learning about my hair everyday. Don't give up, if you are willing to be patient and learn what your hair likes and needs, it will pay off in the end.
