Safety razors have been known to exist since at least 1876 when the single-edge Star safety razor was patented by brothers Frederick and Otto Kampfe. The razor was essentially a small piece of a straight razor attached to a handle using a clamp mechanism. Before each shave the blade had to be attached to a special holder, stropped with a leather belt, and placed back into the razor. After a time, the blade needed to be honed by a cutler. In 1895,

(called 'dry shaving') or beard trimmer. 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.

Wet shaving

There are two types of manual razors: straight razor and safety razors. Safety razors are further subdivided into double-edged razors, single edge, injector razors, cartridge razors and disposable razors. Double-edge razors are named so because the blade that they use has two sharp edges on opposite sides of the blade. Current multi-bladed cartridge manufacturers attempt to differentiate themselves by having more or fewer blades than their competitors, each arguing that their product gives a greater shave quality at a more affordable price. Before wet shaving, the area to be shaved is usually doused in warm to hot water by showering or bathing or covered for several minutes with a hot wet towel to soften the skin and hair. A lathering or lubricating agent such as

(electric shaver) consists of a set of oscillating or rotating blades, which are held behind a perforated metal screen which prevents them from coming into contact with the skin and behaves much like the second blade in a pair of scissors. When the razor is held against the skin, the whiskers poke through the holes in the screen 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 or 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, circular or cylindrical blades (rotary-type shaver) move in a circular motion and oscillating blades (foil-type shaver) move left and right. Hitachi has produced foil-type shavers with a rotary blade that operates similarly to the blade assembly of a reel-type

. The first electric razor was built by Jacob Schick in 1928. The main disadvantages of electric shaving are that it may not cut the whiskers as closely as razor shaving does and it requires a source of electricity. The advantages include fewer cuts to the skin, quicker shaving and no need for a water/lather supply. The initial cost of electric shaving is higher, due to the cost of the shaver itself, but the long-term cost can be significantly lower, since the cutting parts do not need replacement for approximately 18 months and a lathering product is not required. Some people also find they do not experience ingrown hairs (

."Hair Preparations," Ullmann’s Encyclopedia of Industrial Chemistry. Wiley-VCH, Weinheim (2006). Lotions are also sold to reduce skin irritation, but electric shaving does not usually require the application of any lubrication. Mechanical shavers powered by a spring motor have been manufactured, although in the late 20th century they became rare. Such shavers can operate for up to two minutes each time the spring is wound and do not require an electrical outlet or batteries. Such type of shaver, the "Monaco" brand, was used on American space flights in the 1960s and 1970s, during the Apollo missions.

Beard trimmer

The mechanics of a beard trimmer involves rotatory mechanics, crafted with a mini size motor, which rounds at a very fast speed. This motor causes two sets of hinged blades to move back and forth past one another allowing for the hair cuticles to be cut. The main advantage of a beard trimmer, unlike other shaving tools is that longer beards can be trimmed to a short length efficiently and effectively.

Effects of shaving

Aberrations

Shaving can have numerous side effects, including cuts, abrasions, and irritation. Many side effects can be minimized by using a fresh blade, applying plenty of lubrication, shaving in the direction of hair growth, and avoiding pressing the razor into the skin. A shaving brush can also help to lift the hair and spread the lubrication. The cosmetic market in some consumer economies offers many products to reduce these effects; they commonly dry the affected area, and some also help to lift out the trapped hair(s). Some people who shave choose to use only single-blade or wire-wrapped blades that shave farther away from the skin. Others have skin that cannot tolerate razor shaving at all; they use depilatory shaving powders to dissolve hair above the skin's surface, or grow a beard. Some anatomical parts, such as the

Cuts

Cuts from shaving can bleed for about fifteen minutes. Shaving cuts can be caused by blade movement perpendicular to the blade's cutting axis or by regular / orthogonal shaving over prominent bumps on the skin (which the blade incises). As such, the presence of acne can make shaving cuts more likely, and extra care must be exercised. The use of a fresh, sharp blade as well as proper cleaning and lubrication of skin can help prevent cuts. Some razor blade manufacturers include disposal containers or receptacles to avoid injuries to anyone handling the garbage.

s. Putting a warm, wet cloth on one's skin helps as well, by softening hairs. This can also be done by using pre-shave oil before the application of shaving cream. Essential oils such as coconut oil, tea-tree oil, peppermint oil, and lavender oil help to soothe skin after shaving. They have anti-inflammatory, antiseptic, and antibacterial properties. In some cases multi-bladed razors can cause skin irritation by shaving too close to the skin. Switching to a single- or double-bladed razor and not stretching the skin while shaving can mitigate this. One other technique involves exfoliating the skin before and after shaving, using various

, whereas, after cutting, there is no taper. The cut hair may thus appear to be thicker, and feel coarser as a result of the sharp edges on each cut strand. The fact that shorter hairs are "harder" (less flexible) than longer hairs also contributes to this effect. Hair can also appear darker after it grows back because hair that has never been cut is often lighter from sun exposure. In addition, as humans grow older hair tends to grow coarser and in more places on the face and body. For example, teenagers may start shaving their face or legs at around 16, but as they age hair will start to grow more abundantly and thicker, leading some to believe this was due to the shaving, but in reality is just part of the maturation process.

Islam

Sunni

Shaykh Ibn ‘Uthaymeen said: The definition of the beard as stated by the scholars of (Arabic) language is: the hair of the face, jawbone and cheeks, in the sense that all the hair on the cheeks, jawbone and chin is part of the beard and removing any of it is counted as a sin, because the Messenger said: “Let your beards grow,” “Leave your beards alone,” “Let your beards increase,” “Let your beards be full.” This indicates that it is not permissible to remove anything from the beard. However, Ibn Omar, a companion of the Prophet Muhammad, used to cut from his beard anything that outgrew a fist’s length.

Shia

According to the Shia scholars, the length of beard should not exceed the width of a fist. Trimming of facial hair is allowed, however, shaving it is ''makruh'' (religiously discouraged).
