Let's just say that this girl with wavy, coarse, thick hair could not be happier with this product. My hair gets straight and stays straight all day and night. I love the thermal protecting spray, not so wild about the serum as it makes my hair oily. With that being said, it might be great for another hair type, just not mine. I read the reviews before I purchased this product, and some were not glowing. My experience has been nothing but positive, and I hope this helps you!
