My sister introduced this to me last year, I have been hooked on it ever since. Whenever I wear my hair straight and want to curl it, this is my go to product. Great for setting your hair the night before or day of! I have also used this when I wear my hair naturally curly. I prefer this product on straight hair creating the big curl look versus my natural curly hair. There is nothing about this that I don't like except for where I had to purchase this. Until this came in my box, I had no idea it was sold on this site. Now I no longer have to go out of my way to find it. Thanks Birchbox!
