@Nzeee (sorry I had missed one e
), I think when 4B hair is well moisturized internally, and not manipulated, it just takes up its natural pattern: coily. My mom's hair was very dry because her only moisturizer was not water-based. She also had never DC'd her hair until I introduced her to it. That's the only change we made in her case.
I also discovered my hair was coily when I discovered DCing. Prior to that, I'd never seen my hair look any other way than the way my mom's looked.
As far as afros are concerned, I've always just patted my afro into place. But since introducing S Curl into my life (and my mom's) the moisture in the product causes the hair to curl back into itself so that the afro just forms w/o much effort. I think another mistake people make when trying to create an afro is use a comb with short teeth. You need a pick to create a good afro because the teeth allow you to reach all the way from the perimeter of your hair to the center so that if you can go around your head, lift hair to the afro size you want, and not mess that up while combing other sections. Then you can just pat it into shape, but S Curl just seems to make the hair coil back.
You can see from the close-up of my afro, that the hair ends are just curling back to form a round shape:
BTW, combing your hair is manipulating, which might explain why your 4A section isn't clumping. If you comb your hair when it is semi-dry or just damp, and especially if you comb it w/o some moisturizing or sticky-ish product, then your hair won't really clump. I bet if you were to shampoo your hair or clarify, then DC with heat using a product like Aveda Damage Repair or Emergencee or AO GPB and then you followed that with a moisturizing regular condition, only combing your hair when slathered with those products and then rinsing, you'd see your hair clump more in the areas with bigger coils.
I don't do WNGs so I'm not the best person to give tips on definition but I'm guessing if you DC and then condition with some uber moisturizing conditioner (Aussie Deeee...p?), that you'll see hints of coils even at your ends.
I don't know how often you dust your ends (I apologize if you already shared this but I'm too lazy to go back and read), but that does make a difference too. You don't need to cut off too much. I just put my hair in tiny twists all over and snip off this much__ from each one, and that keeps my ends behaving nicely.
