Have you heard of a shampoo, condtioner, cream and spray system called “Living Proof?”. There was an article in the NY Times which mentioned a scientist at MIT who was involved in its development.
It claims to work very well in increasing hair volume.
I did find an article in the Wall Street Journal about the company signing on actress Jennifer Aniston as their spokesperson (and as an investor), but I’m not otherwise familiar with their product line.
The MIT credentials sound nice, and perhaps their products may work for conditioning or volumizing hair. The hair styling products market is huge, so I can understand the need for a celebrity endorsement to stand out from the rest. I wouldn’t suggest this is the answer to thinning hair, though (nor does it seem that they’re claiming these products are hair loss treatments).
