CHI is a brand that I not only love and use, it is a brand that I trust and would recommend to others. I use their hot hair styling tools, hairspray, frizz control serum, shampoo and conditioner, etc. The CHI Iron Guard Protection Spray is the only product by them that I have not re-purchased. The pro of the product is that it smells fantastic as most of their products do - I actually enjoyed using it for the scent. However, I did not find that it did much of anything in regards to protecting my hair. I straighten or curl my hair twice a week at the most and I never blow dry. There is no reason for my hair to be as damaged as it is considering I use the protectant and have limited use with hot tools. Since switching brands and continuing the same hair care routine I have found that my hair looks and feels much stronger and less damaged. A great product line, but not a very good product.
