"I was introduced to the Matrix Amplify product line 5 years ago by my stylist and was amazed at the difference it made in the volume and overall thickness of my hair. I had always had 'Rosanna Rosanna Danna' type thick hair, however I had gotten ill and realatively lost half the volume I normally had. Amplify to the rescue! It really works! Along with the conditioner you can't go wrong. Loyal customer for life. A must try for sure!"
