Bottom Line

The KERASTASE Smoothing Anti-Frizz Sulfate-Free Shampoo with Morpho-Keratine is celebrated for its ability to repair and smooth hair, particularly in difficult water conditions, and its sulfate-free formulation appeals to those looking to maintain hair health. However, concerns about the product's watery consistency and potential authenticity issues have been raised. It provides a luxurious and nourishing experience but might not be suitable for everyone, especially those with concerns about hair loss or requiring frequent washing. If you've experienced disadvantageous effects with this product, it may be worth exploring other options from the Kérastase line or comparable sulfate-free, nourishing shampoos that align with your hair needs.
