some new dread questions
Bumps and loops mean that your sections are knotting. As knots and tangles form different hairs grab hold of other hairs further down or further up the shaft. That's where the loops come from. It's a good sign. They do eventually flatten out, but in the end, they are still there, to a point, but look more like texture than loops. You'll never end up with perfectlysymmetrical locks.
As for combing out the tips I'd recommend jojoba oil, before olive oil. While olive oil will work, jojoba is closer to the natural oils that your scalp and hair produce. So it's a safer bet. Just dab a little bit on the tips and use a soft bristled brush (toothbrush is better), and gently brush them out
