This is a staple beauty product for me. It retails around $10, and it attaches to your dryer to evenly distribute heat on your hair, similar to a beauty salon chair. I liberally apply hair oil such as pure jojoba, protein masks, deep conditioning treatments, etc. to my hair before I use this to allow for greater absorption. I notice a huge difference when I both do and don't use this product with my hair treatments. Its very convenient, you can watch TV or a movie while you have this on. It is so worth the purchase, you won't regret it!
