Summary: so-so product.
Silk Therapy is a silicone hair product for smoothing and adding shine to your hair. It's marketed as a hair treatment, although I don't understand the science of silicone treating your hair. I think it might protect your hair a bit from heat.
Cons: It has a very strong chemical smell. Maybe I got a bad batch? If I apply it on wet hair, the smell dissipates, but on dry hair, it's rather bothersome. I feel uncomfortable inflicting it on my coworkers.
Pros: It does an okay job of smoothing my thick hair, whether applied wet or dry. Perhaps I need to apply more product.
