Excellent Product - Travel Size Unavailable
I have used this product for years. The shampoo/condition itself is excellent and does what it claims to do. However, I travel. A 12 oz. bottle is too unwieldy. The TSA limits travelers to a 3.4 ounce (100ml) bottle or less (by volume) in carry-on luggage. Why isn't it available in a 3-ounce size? There is a 4-ounce size (for some reason), but Amazon (for some reason) doesn't sell it eligible for Amazon Prime.  For those reasons, I have to downgrade my review by two stars, for the size/packaging and shipping problems.
