Hair conditioner may also be used to improve hair s texture and manageability.

The surfactant is rinsed out with water along with the freed dirt and dust it bonds to. There are also dry shampoo s, which are powders which remove sebum from the hair by soaking it up prior to being combed out. Hairdressing main Hairdressing Most hairdressers, in countries such as Canada, the U.S., and European and Latin American countries, offer a hair wash as a service before or after a hair cut. This is usually done to make hair more manageable for the hairdresser who will be performing the hair cut. After a hair cut, it can help remove any loose strands of hair that may be bothersome to the client. It is also quite a relaxing practice, and many clients enjoy a hair wash as their favourite part of a hair cut. Hairdressers use specialized basins to perform a hair wash, and these can be either forward or backward style. In the backward version which is more common , the client sits down in a chair, and leans their head back into a sink, with the hairdresser standing behind them.

In this style, the client simply sits in a chair as they normally would, while a hairdresser applies shampoo to their hair and adds water. They then rinse out in a basin.
