Andrea, a reviewer, recently tried out the EXTRA VOLUME SHAMPOO by Moroccanoil along with the conditioner. With fine, thin, and frizzy hair, she had been on the lookout for a volumizing shampoo that wouldn't weigh her hair down. According to Andrea, this shampoo exceeded her expectations. Unlike other products that left her hair feeling heavy and greasy, the Moroccanoil shampoo provided her with impressive volume. Even after three days without washing, her hair still maintained its volume without any greasiness. Andrea was so impressed that she plans to order two more bottles, despite her current ones still being full. Overall, she highly recommends this shampoo to anyone in search of added volume without the unwanted heaviness.
