content: I bought this for myself, and upon using it just once the difference in my skin and hair was obvious. No itching or dryness! I promptly bought another for my mother- she is in her 80s and has said this has helped her skin and hair so much. We gave them as gifts to many people in 08, and every one of them has gone on to buy one to give as a gift to someone they love too. Honestly; easy to install, easy to use, instant results- great value for money!
