"I LOVE this product. I struggle with finding good products because I have thin fine hair. I was more than pleasantly surprised with this product. Fact, I plan to buy another bottle because I love it so much. It does not weigh my hair down. It keeps it light and fluffy and gives it volume without making it oily or heavy. I’m extremely happy with this product."
