I'm very picky with hair products, and I love this one so much. I skipped using a heat protectant spray for years because I hated how greasy it made my hair. Not with this one! It's light and "dry." The only thing I don't love is the smell at first (very strong lemon-y smell, like a cleaning product), but it dissipates quickly. Leaves my hair very soft after blow drying and heat styling. And this 4-pack is such a good deal! I'm thinking maybe it's because they changed the packaging. Oh well, works for me!
