Honestly this is one of the best products I have ever used for my hair. I have been able to increase volume and thickness of my hair. The product is versatile and can be used in conjunction with other products as well. The application is very easy and I usually use any excess product on my skin for the added benefits. If you have fine hair your hair will get oily if you don't wash out so I just apply at night and wash out the next morning. Overall my hair is so much healthier and I am really happy I found this. Also I apply this 2-3 times per week overnight and wash in the AM. It will stain your pillow case so sleep with a bonnet or something with breathable material.
