That's a lot of steps
but if it works for you by all means continue.
I wash and detangle in the shower. This is the only time I detangle and only time I use a comb. Everyone's hair is different. I consider my hair to be predominantly 4a with a sprinkle of 3c in my bang and a sprinkle of 4b above my left ear. For my hair I can detangle in the shower in about 5 to 10 minutes tops. I apply my DC in front of the sink with just my hands Sometimes I'll do it in four sections but most of the time I don't. Then place plastic cap on my head and then sit under dryer for 30 minutes. I then jump back in the shower and rinse. If I'm feeling lazy I will rinse leaning over the tub. I don't have to detangle again. I will then immediately put my hair into four sections. I start applying my leave in to section on right rear. I will separate that section into A subsection I then will spray the smaller section with water then apply my gel to the smaller section. Then I will either rake in shake/shingle/or finger coil that smaller section. I then go through my whole head in this fashion.
I would also like to add that I DC once or twice a month. I shampoo and style my hair once a week. I can wash and style my hair in an hour. If I sit under the dryer that will add an extra hour. However I prefer to air dry I think it looks better.
I did recently purchase the kareco tangle brush you mentioned in random thoughts. I have not gotten the chance to use it yet since I'm currently in braids. I generally don't like using brushes. I have a denman and one of those wooden brushes. They both just sit in my cabinet because I feel they like they rip out too much hair even though I was always gentle and only used them on small sections. I also feel they cause my hair to have too much frizz and less definition. I do use an old fashioned boar bristle brush for when I wear puffs or ponytails.
