How can I bring shampoo without bottling it separately?

Generally, when you go out, there is bottled shampoo, or disposable shampoo or shower gel. Of course, don't panic if you use it up or not. If you are going to stay in a hotel, the hotel will usually prepare it and give you disposable shampoo. But if you really want to prepare it yourself, you can also bottle some with smaller water. If you don't have a water bottle, you can also use some small bottles and boxes of skin care products that have been used up temporarily. If there are no conditions, we will create our own conditions. Of course, there is another way to buy that little shampoo in the store for the time being. Some shops have special disposable shampoos. I hope I can help you.
