My hair. I live near the equator, so it gets pretty hot in summers and cool in winters, by my hair feels super oily like all the time. Had I been a slacker, I would not wash it or give a sh*t. But I have to shampoo it twice DAILY to give them volume and cleanse the grime!
Otherwise they feel disgusting :S
My wakeup bath consists of rinsing it with hot water, applying shampoo, washing away the shampoo and applying conditioner. I repeat the same procedure in the afternoons or evenings. Hence, I have to shampoo it each time I take a shower. All my family members have soft silky hair and I'm the black sheep >.>
