I really enjoy having the shampoo bars for travel. They're convenient for carry-on and it's nice to not worry about liquid messes in my luggage. Plus, I love that they're package free. Because of how much they lather, you only need to have the bar go over your hair a few times, making the products go a long way. I have not tried all of their bars, but I've been happy with them so far. My only complaint is that they can strip a lot of oils from the hair, in my opinion. I have straight hair that lacks volume and live in the southwest, therefore, I need a product to retain a lot of moisture (aka., conditioner).
