Don't you hate it when you buy a full size hair product and you end up not liking it? You don't want to throw it away so you throw it under your sink and let it collect dust. Bumble and bumble gives us yet ANOTHER reason to love them by providing 2oz sizes of their products. It's a great way to try a product out without spending a lot of money. We love this Thickening trio with Thickening Shampoo, Thickening Conditioner and Thickening Hairspray (a best selling family) and the stylish reusable travel bag they come in!
