I do like this product, but it wasn't a miracle for me. With regular use I did notice a difference in the health of my hair (a good one, of course). I don't feel that it did something so miraculous as to be worth $27 though.
Just for anyone considering picking this up, it does retail for $27 but I got mine on Amazon, new for $17 with free shipping.

I love this hair mask! I have dry and damaged hair and my hair feels so soft and silky after I use the treatment. You do have to leave it in your hair for 7 minutes before you can rinse it out but all treatment/mask are like that. This product is excellent in moisturizing and rebuilding damaged hair.
