Absolutely love Kerastase! Love the packaging of the sample as it had a pump like the full size. The product was a nice consistency and had a pleasant/not overwhelming smell. I strictly only apply to my ends when wet. For my styled beach waves, I mix a pump w pomade and work into my hair. Perfect combination. Didn't see much of a difference from other oils/serums, but I LOVE this brand, so know it's a good product.
