I finally watched the series. I'm always curious about people with loose curly hair who claim to know what's best for a tightly coiled texture. Detangling on dry hair doesn't work for everyone although she said that is her routine on every client. I hope the newly natural crowd will do a bit more research before following this routine simply because Taren posted it.
Most of us have seen Naptural85 and Kimmaytube on YouTube grow their hair to great lengths and neither detangles their tightly coiled, dry hair with a paddle brush with plastic tips.
A paddle brush with plastic tips on dry curly hair? That is a recipe for damaged ends, at least on my tightly coiled hair. You could hear the brush snapping off pieces of hair. If the brush was just removing shed hair, there would be no snapping sound. I think the paddle brush idea could work to remove shed hair before washing, but one without those plastic tips and when used with some oil or a conditioner to avoid snapping off healthy hair. You need the shed hairs to slide out (which is why some oil, water or conditioner with slip is needed). In the video is sounded like the hairs were being ripped out.
Some hair problems can be solved with a trim but I doubt it's 90%. Healthy hair practices after good trim can solve most natural hair problems. Finger detangling, especially on dry hair, is far better than using a paddle brush with plastic tips. A second option after finger detangling is using a modified denman brush on damp hair (water/oil/conditioner). Of course this is only if you're on a length journey.
If you just want to maintain a style, then her tips seem fine to speed up your wash day and will likely result in needing a trim every 8 weeks.
