I have 4c hair. Locs are the most practical style for us. However, most 4c women with long hair do not focus on completely detangling and neither do I. It's tedious because our hair loves to tangle or loc. Instead, I finger detangle and get rid of shed hairs. Sectioning is very helpful.
Also, keeping it stretched in braids or twists or threading will make detangling easier.
Everyone's hair is different, lol.
As I said, those suggestions do not work for everyone. Maybe you don't need to fully detangle your hair, but in order to restyle my hair, it needed to be detangled. I have too much hair, that's too thick, and wraps around itself too much for it not to be a chore for me to handle solo.
Twisiting made it even worse, which is what made me realize that my hair type needed to be straightened with heat, or put in locs. None of those pretty air dried buns, twist outs, or other styles for me if my goal was to avoid any type of heat straightening. I even tried that African threading and that was a disaster as far as knots go.
People need to find what works for them because you can look at youtube suggestions all day and find yourself frustrated when what works for "everyone" does not work for you.
That doesn't mean that "tough" hair isn't beautiful. It's great, it's beautiful. Yet even still, for some, it's too much work for them to handle alone.
