My routine is quite bad for split ends, but i get regular trims and it's worth it for my extremely fine flat hair. I wash my hair with volumizing shampoo and use a small amount, focusing mostly on my scalp and letting it wash through to the ends. I only condition the very tips of my hair. then i let my hair sit in a towel for a while. Next, i comb my hair with a wide tooth comb. I then spray my hair all over with herbal essences heat protection spray (helps with texture too). After that, i lift sections of my hair, about four section on each side that cover my entire head (totaling 8-i have a middle part), and spray 3-4 sprays of john frieda root booster on the pieces of hair. Then i blow dry up my hair upside down, focusing on getting volume wherever i can. brush though your hair slightly if you feel a little stiffness from the product. Lastly, i flick my hair back into an extremely high, volumized bun that i push up with a big hair clip. I leave it like that for a while, and then when i go to bed i take it out, brush through the ends slightly, and sleep with my hair fanned out behind me, above my head on the pillow so that i don't flatten it. It's a sort of weird routine that i have developed to work for my after years of struggling with flat hair, and for me it works extremely well. The only down side is that it is a nighttime routine, although it would probably work just as well in the morning if you left it in a high ponytail instead of a bun for a while.
