In using 4 * + hotels, if the products are good brands, (Hermes at Sofitel etc), I tend to take some with me for use on the plane. ideal for the limits of security, & hardly provided on many carriers these days, even in Premium cabins.
If you want to be green, then you could always try (with some) of these, to put yr own favourite items in them at home. Useful for hair gel that is usually too bulky to carry. When you have slept on Board, saves frightening the crew with your “out of bed” hairstyle!
