Matrix Biolage has a new product in a pretty pink bottle - a Strengthening Treatment. If you have thin or fine hair, use this. It won't weigh your hair down and does make it shiny. The website says "Strengthening Treatment is an ultra-lightweight, scented oil that strengthens thin, fragile hair for ultimate vitality. Formula with Polynesian Tamanu Oil boosts resistance to breakage while leaving hair replenished and beaming with exquisite shine."
It is part of the ExquisiteOil Collection. I also tried the ExquisiteOil Protective Treatment and that weighed my hair down. I have been using it to condition my hair and it works very well. Two nice products.
For some reason, I always end up having good luck finding sales at Best Cuts on products - maybe I just have good timing but I always check there first.
