Remove excess oily buildup and styling product from hair by applying shampoo to head without water. Rub into scalp as usual, and let it set for 3 minutes - it won't lather, but it will work to cleanse hair by pulling out debris. Follow with a regular shampoo and conditioning routine.
Condition Wisely
Take care not to apply conditioner directly to scalp. Instead, work into the ends of hair, focusing on areas prone to breakage and split-ends. If you're concerned about oil, a good rule of thumb is to focus conditioner application from the ears down where hair is older and dryer and still needs moisture.
Take It Easy
Consider easy wear, finger-styled looks without a lot of muss and fuss. Too much combing and brushing stimulates oil production, which can be a big problem for people with excess oil. Brush lightly when you do brush, and try to stay away from the scalp if possible.
