I'm only at BSL stretched out. Right now I'm having good results with a water regime and I have fine, dense 4a/b hair.
1. I do protective styles 5-6 days a week.
2. I wash my hair with water.
3. I follow with a final rinse of 1/2 tsp of ACV in a gallon of water.
4. Every evening I massage my scalp and move the sebum down the lenght of my hair.
5. I spritz the hair with water and put it up for the night.
6. I sleep with the hair covered
7. I use a smooth, seamless wide-toothed comb.
Since I started distributing my sebum down the length of the hair I've found that I get way less tangling and that the hair holds what ever shape I decide to give it.
My twist outs, brad outs, bantu knot outs what have you have been outstanding.
The only change I'm making to my regime, right now, is that I ordered a super soft, goat-hair brush and I'm going to try it out as a method of spreading my sebum more evenly throughout the hair.
I tried a boar bristle brush this week and while I liked the way it spread the sebum, it snagged and snapped some of my hairs. Boar Bristle is too rough for my hair. It was the first time I'd brushed my hair in 7 or 8 years.
The most effective way I've found to keep tangles at bay is not leaving any kind of style in too long and not wearing the hair out too much. Day to day I wear a variety of buns, braids and textured updos. The hair doesn't have the opportunity to tangle up and by styling my hair fresh each day I can deal with any small tangles as they happen. Protecting the hair in this way has cut my detangling time in the shower when I wash my hair down to a minimum.
