I love Amp. It is such an important part of my hair regimen, as I have thinning and hair loss. I also use the HairMax laser, Great Day hair powder for my scalp, and the Wen hair products. After blow-drying my hair, I put on a teaspoon or less of Amp and work it through my hair. It gives such volume, and it looks like I have so much more hair. I brought it to my stylist today and had her use it on me and she was amazed. It smells good too. Yes, it is expensive for the little jar but it will last me for so so long. I make my hair go big and crazy with it while working it in, and then I style it and calm it down again with my fingers. After sleeping on it you can just squeeze your hair again and the volume and fullness comes back. They have this at Ulta.
