So for products/routine, whew!
Right now I'm styling with FSG or LOOB under LASL Power Spikes. I live in high dews so I need super gel for frizz control. I rinse out my condish upright under cool running water, this is when I finger comb any knots and generally smooth out any snarls/tangles and make sure all the clumps feel smooth. Then I take the fsg/loob and rub between my hands and smooth it on the clumps from root to tip. My hair is still dripping wet at this point, so I smooth lightly so I don't get rid of the water. I go in sections, two in the front and two in back until everything feels coated. Gel goes on the same way. Then I'll flip upside down and scrunch and pump a few times to make sure everything is evenly distributed. It should feel "squishy" so if it doesn't I'll add some extra water. This is kinda like the supersoaker method. Then out of the shower and into a tshirt plop for a few minutes. When I take my hair down I'll check for those pesky little stringlets that never want to clump and stick them onto their neighbor clumps. I finger style those, and then diffuse.
I can't believe how long and complicated this sounds typing it out because I have gotten quite used to doing my styling in the shower while also getting clean. I hope it helps
