Shaving

A shaving is also a thin sheet of wood removed from the surface of a piece of wood, e.g. by planing.

Shaving is the removal of body hair, most commonly facial hair, using a razor or any other bladed implement to slice it down to the level of the skin. Shaving is a common method of depilation, and is most commonly used by men to remove their facial hair. Both men and women sometimes shave their chest hair, abdominal hair, leg hair, underarm hair, pubic hair or other bodily hair. Women and men may also shave the hair off the top of their heads, but this is a much more common practice in men. Shaving the head is often associated with the military and competitive sports such as swimming and extreme sports.

History

Before the advent of razors, some humans removed hair using two sea shells to pull the hair out. Later, around 3,000 BC, when copper tools were developed, humans developed copper razors. The idea of an aesthetic approach to personal hygiene may have begun at this time, though Egyptian priests may have practiced something similar to this earlier. Alexander the Great strongly promoted shaving during his reign in the 4th Century BC.

Islam requires that all men and women shave the pubic area.

Shaving methods

Shaving can be done with a manual wet razor or an electric razor. If a manual wet razor is used, some lathering or lubricating agent such as shaving cream, soap, gel, foam or shaving oil is normally applied to the area to be shaved first; this helps avoid a painful razor burn. These lubricate the area to be shaved, moisturize the skin and lift, soften and swell the hairs. This enhances the cutting action and sometimes permits cutting the hairs deeper below the surface of the skin.

Manual razors are available in many different styles but the disposable, disposable cartridge or razor has come to dominate. Current multiblade cartridges claim to improve shaving and have seen a design war with manufacturers adding greater numbers of blades than competitors. The antique safety razor and straight razor continues to be used. Shaving with these razors requires some practice.

Wet shaving methods

These methods would be used with disposable cartridges, disposable razors, safety razors and straight razors. See

Shave once method

• Wet face (or other part of body to be shaved) with hot water
• Apply shaving cream or lubricant
• Shave once in direction of the hair nap (grain) (Use the fingers to detect the direction of nap by rubbing over the skin. One direction will feel more resistance than others, that direction is against the nap)
• Rinse razor often

Shave twice method

Some tough beards may get a closer shave by shaving again immediately after the first shave , but this time going in the direction against the grain. Others may find this leads to cuts, soreness and ingrowth of hairs.

• Apply shaving cream or lubricant again
• Shave again in direction against the nap (grain). Again feeling for where the bristles are coarse and still standing above the skin.
• Rinse face in cold water
• Apply aftershave if desired.

Shaving soap or cream

Shaving cream acts as a lubricant and also as an indicator of which areas have not been shaved.

Use a styptic pencil, made primarily of alum, if a cut occurs.

Electric shaving methods

Electric razors consist of a set of rotating blades held behind a perforated metal foil so there is no possibility of them coming into contact with the skin. Bristles poke through holes in the foil and are sliced by the moving blades. In some designs the blades are a rotating cylinder, in others they are one or more rotating disks , and in others a set of oscillating blades. Each design has an optimum motion over the skin for the best shave and manufacturers provide guidance on this. Generally for circular blades it is a circular motion and for cylindrical or oscillating blades it is up and down.

Many pre electric and post electric lotions are sold but electric shaving does not usually require the application of any lubrication to be effective and can be done dry.

Shaving aids

Shaving without the aid of shaving cream, gel, soap, or oil is known as dry shaving. Electric razors are typically used without external shaving aids, and were originally called dry shavers. However, modern electric razors often lubricate the skin slightly.

The removal of a full beard often requires the use of scissors or an electric (or beard) trimmer to reduce the mass of hair, simplifying the process.

Side effects of shaving

Shaving can have numerous side effects, including cuts, abrasions, and irritation. Some people with curly hair have an adverse response to shaving called pseudofolliculitis barbae, or "razor bumps" due to ingrown hairs. Many side effects can be minimized by using a fresh blade, plenty of lubrication, and avoiding pressing down with the razor. Some people choose to use only single-blade or wire-wrapped blades that shave farther away from the skin. Others cannot use razors at all and use depilatory shaving powders to dissolve hair above the skin's surface.

Many people traditionally believed that shaving would cause the hair shaved to become thicker and darker. However, this bit of conventional wisdom has been disproven. The resulting stubble only makes the hairs seem to be thicker, as a shaved hair has a blunt end as opposed to the tapered end of an unshaven hair, and because hair is often darker in color near the root. Clinical studies have demonstrated that shaving does not have an effect on hair growth rates or density (see medical data below)

Aftershave

Many men use an aftershave lotion after they have finished shaving. It may contain an antiseptic agent such as alcohol to prevent infection from cuts, a perfume to enhance scent, and a moisturizer to soften the skin.

Cuts

Cuts from shaving can bleed for about fifteen minutes. Common methods used to stop bleeding include putting alcohol on a cotton swab and pressing it onto the cut until the bleeding stops, as well as tearing off a small piece of toilet paper and placing it onto the cut. The latter method, however, can be undesirable for aesthetic reasons. Products such as styptic pencils can also be used to stop bleeding. Placing a small amount of petroleum jelly on a cut after most of the bleeding has ended can stop the bleeding without forming a scab. Shaving in a cold shower can help prevent bleeding as well, because blood flow to the skin is reduced in these conditions due to vasoconstriction caused by the cold water.

Additional facts (not from the source above)

• In some professional sports, players will not shave if they are winning games due to a superstition that a change in their routine will change the outcome of games. This beard is colloquially known as a playoff beard as it originated in the NHL playoffs. Fans often practice the same tradition of not shaving in support of their team. Another example of this is in the Australian cricket team, where the players will start a test match clean-shaven and not shave during the length of the 5 day match.
• Beard hair is approximately as hard as copper wire of the same thickness.
