A hairdresser will typically address all things related to the appearance, styling, and grooming of hair on the head. A hairdresser will listen to the client first, and make sure they have a clear expectation of the desired results. Hairdressers will often refer to photographs and pictures in beauty & style magazines to visualize the look desired by the client. Hairdressers often must seek continuous training and education in order to be able to offer clients the latest style or cut.

Many hairdressers take part in hair competitions in order to keep up to date with the latest styles and cuts. These competitions showcase colouring, styling and cutting techniques. Salons encourage hairdressers to partake in competitions, as an award winning hairdresser will be great publicity for a salon, and the hairdresser will often end up gaining a large client base.

The largest task often performed by hairdressers is the actual cutting of hair. Clients seeking a new look or just requiring a trim will seek out the services of a hairdresser on a regular basis. Hair dressing is also referred to as hair styling, and is the process of styling the hair in a desired way to enhance the appearance of the individual. There are many styles that hairdressers must know in their profession including:

• Curly styles, and knowing the most flattering way to cut curly hair
• Straight styles, and knowing how to cut poker straight hair
• Short styles
• Long styles
• Complicated up-do styles for weddings and formal events

Chemical treatments to hair can change the way hair looks and feels. Hairdressers administer a chemical relaxant to curly hair making it smooth and straight. Chemical perms cause a semi-permanent style such as curls or waves in otherwise straight hair. Colouring and highlighting hair often requires patience and knowledge of chemicals to create the perfect colour. Colouring for multiple shades can be quite complicated and tedious for the hairdresser.

Hairdressers also serve as an expert in the area of hair care and often will sell products that they are commissioned to sell or would like to recommend to clients. Some hairdressers go on to develop their own line of professional hair care products. Hairdressers may serve as consultants or editors for beauty and style guides.

A less common area of hairdressing exists in the realm of hair restoration services and products. Hairdressers can be licensed to handle hair plugs and skilled in the art of styling toupees and artificial hair. Wig styling can require special training as well.
