Review: Shiseido Tsubaki Shining Hair Treatment with Tsubaki Oil EX

I don't know if it's the indoor heating, the weather, the new hairstylist, the whatever, but my hair has been getting dryer and more frizzy since October. I've tried the Asience Inner Rich Hair Treatment before which came in a package along with the Asience shampoo and conditioner. I also bought a Shiseido Tsubaki shampoo and conditioner package which came with this hair treatment.
