I was happy with the product as it leaves hair smooth and protected. Unfortunately, it's the lid that lets this product down. I've purchased the 150ml twice and both times the lid broke while closing, leaving me with a constantly opened product. Not great if you want to travel with it, it could be decanted into another container I guess. I expected higher quality from Kerastase and although I like the product, I won't be buying a third time. I believe there are other brands that have similar products with better packaging.
