I don't use a hairdryer on my hair
I always air dry. I used this in the morning after my hair was air dried and before using a straightening iron . I didn't feel like it was protecting my hair from the heat. My hair still felt a little dull after I straightened it. I used it a couple mornings later though... I used it before I straightened my hair with my straight iron and then I spritzed a little bit on my hair afterwards and I loved the way my hair felt moisturized and smelled. My hair also shined and felt flowy all day long. I really like this brand. Thanks Birchbox for introducing me to Living Proof!????????
