Hair dressing may include cuts, weaves, coloring, extensions, perms, permanent relaxers, curling and any other form of styling or texturing.
Length and trimming
Hair cutting or hair trimming often involves creating and maintaining a specific shape and form. Haircuts can be used to define a hemline along the ends and edges of longer hair. Hair cutting may include shaving the head. In some settings, hair cutting, creating forms and shapes are an expressive art form. Hair cutting often involves considerations of body proportions, hair density and hair type, face and head shape from all views (profile, 3/4 and 360 degree, from above and from below), overall bone structure, and pattern of how hair lies or falls. Hair shape and length are often derived from concerns regarding personal expression and aesthetics (examples: dreadlocks, punk hair, the business haircut/style, very long hair), religion (for example, Pentecostal faith among others), social and cultural values. Hair is often a physical expression of one's sense of self, of a desire to present oneself to and amongst a community, of social status and roles, and of cultural values. Such expression may involve adding ornaments to the hair, or partial or full hair coverings (such as a Kippa, Hijab, or a Turban).
Although trimming may beautify hair by removing damaged or split ends, cutting does not promote faster growth. Nor does trimming remove all damage throughout the hair. Damage can occur anywhere in any length of hair. Trimming at regular intervals is only necessary for maintaining formed shapes.
There exist ways to trim hair oneself as outlined in places on the internet and hair care reading materials.
Wet hair stretches rather significantly in length. Curly hair will unfurl a fair amount when fully wet, and different areas of the hair may have a larger degree of curl or different direction of curl than others. Thus, cutting curly hair while wet may result in uneven lines or unexpected results with regard to actual length. Further, curly hair, in particular, once dry, might appear visually to have an uneven line depending on how the curl coils back up. Lorraine Massey, author of Curly Girl, specializes in the care of curly hair types, and has designed a specific method for trimming curly hair to avoid these problems. The reason stylists like working with wet hair may be related to weight. Wet hair is heavier and may be easier to manage in a cut/style situation since the hair remains in place thus holding a line and making it easier for the stylist to create a form.
Detangling: brushing and combing
The point of detangling is to organize hair, usually in the same direction, and eliminate knots, snarles, tangles, and any hairs that have shed naturally.
There are all manner of detangling tools available in a wide variety of price ranges. Combs come in all shapes and sizes and all manner of materials including plastics, wood and horn. Similarly, brushes also come in all sizes and shapes. There are also a variety of brushes in various paddle shapes. Most benefit from using some form of a wide tooth comb for detangling. Most physicians advise against sharing hair care instruments like combs and clips, to prevent spreading hair conditions like dandruff and head lice.
The old notion that 100 brush strokes a day produces beautiful hair is somewhat false. Too much brushing may injure the hair, especially with brushes that pull the hair or scratch the scalp. It remains a possibility that the dictum of 100 strokes a day derives from the era when Boar Bristle Brushes were more commonly used, well before the invention of plastics and a time when more organic materials were used to create hair care tools. Usually in conjunction with the idea of 100 strokes a day was the suggestion that hair will 'shine' and be 'soft' to the touch. That said, a person skilled at brushing without hurting the follicles can brush down the natural oils to the ends of the hair fibers, thus extending the natural protection of skin oil. Notice that if the skin has been depleted of oils by shampooing, this won't work.
Drying
Hair dryers speed the drying process of hair by passing air, which is usually heated, over the wet hair shaft, accelerating the rate of water evaporation.
Excess heat may overly dry the hair, increasing the incidence of splitting or other damage. Hair dryer diffusers can be used to diffuse the stream of air flow so it is weaker but covers a larger area of the hair.
Hair dryers can also be used as a tool to sculpt the hair to a very slight degree. Repeated blowdrying can slowly train hair follicles towards the desired direction. Proper technique involves aiming the dryer such that the air does not blow onto the face or scalp, which can cause burns.
Braiding and “Updos”
Tight or frequent braiding may pull at the hair roots and cause traction alopecia. Rubber bands with metal clasps or tight clips, which bend the hair shaft at extreme angles, can also have the same effect. Braid combined with multiple pony tails is very popular among party going women. Multiple pony tail can be easily made on a newly washed hair or seasoned hair. Don’t rip or break your [hair][2] while brushing.
For example, hair drawn in a direction other than its natural growth pattern (hair types come out of the hair follicle in particular patterns for curly, body, straight; and also, hair grows in a pattern about the head so that it hangs or forms the way it does for humans). If hair is pinned too tightly, or the whole updo slips causing pulling on the hair in the follicle at the hair root are other scenarios that can cause aggravation to the hair follicle and result in headaches.
