Query: Wonderful, Amazing Product!

I used this product just once and I automatically noticed the difference. I have very curly, long, thick hair and I use the flat iron a lot whenever I want to wear my hair straight so I have some heat damage. This product left my curls feeling very silky after I rinsed it out and the curls look much nicer as well. I will definitely use this product once a week.
