Silk Amino Acids - Smooth and Shimmery Hair

What comes to mind when someone says "silk"?  Smooth.  Shimmery.  Soft.  Shine.  Well, imagine bringing all these characteristics to your hair.  How?  Silk amino acids (SAAs).

SAAs are hydrolyzed from silk protein and help to impart smoothness and shine to the hair and skin.  In the hair care community, they are a popular addition to leave-ins and deep conditioners.  In the skin care community, they may be added to lotions and moisturizers to achieve silky skin.

SAAs are on my 2011 wish list, so unfortunately, I do not have a personal review to share with you all.  However, the following links are good places to start for anyone interested in experimenting with SAAs:
