So lately, after I've taken a shower, I blow dry it, and it still feels greasy, like there is still shampoo in it. Usually, i'm in the shower from anywhere til 45 minutes to an hour. I spend about 30 minutes just rinsing it. But lately it hasnt mattered how long i stand in the shower rinsing my hair, it still feels greesy. I straighten it a lot and blow dry it a lot. Could my hair be damaged? How can i make sure i have all the shampoo out of my hair, so i dont have to take two showers. The other day i took 3, the first time i took a shower, my hair still felt liek it had shampoo in it, so i took another one and just rinsed my hair, still felt like it had shampoo in it, took a third one, still felt liek it had shampoo in it. so i just said forget it. I tried changing my shampoo but it did the same thing. i dont know what else to do. Im going to get it thinned out.. again.. in a few days. idk any suggestions?
