Hair wash
The shampoo is part of hair care. It is a cleansing and cosmetic process to keep the scalp hair clean by washing it with shampoo or other cleansing products and water. Even hair conditioner can be used to improve texture and shine to the hair. Often, "two-in-one shampoos," a combination of conditioner and shampoo, are used as a substitute for this.
To make the hair less greasy, a surface-active substance in the shampoo is first massaged into the hair with a little water. The hair is then rinsed with plenty of water, with the dirt and dust released by the laundry being rinsed out with the water as well as the rest of the shampoo. There are also dry shampoos that stick to the hair before being combed out, making the hair less greasy.
Comb
Most hairdressers in countries like Canada , the USA and European countries offer a hair wash before cutting so that they can handle the hair more easily. Once trimmed, this also often helps remove any loose hair that could be annoying to customers. It is also relaxing , with many customers saying that washing their hair is the best part of a visit to the hairdresser for them. The hairdressers use a special basin for shampooing, which can be directed either forward (forward style) or backward (backward style).
Most of the sinks are rear-facing. The customer sits down on a chair and leans back, placing his neck in a hollow in the edge of the pool. The hairdresser stands behind him while washing.
If the sink is facing forward, the customer will lean forward over it; the hairdresser stands over him to wash his hair.
In some countries, such as China, it is not uncommon to see hairdressers washing without a basin. The customer sits on the chair he is sitting on while cutting, while the hairdresser rubs shampoo into the hair and adds water. Then this rinses it out over a basin.
