An epilator is an electrical device used to remove hair

Hair removal

Hair removal is the removal of body hair, and describes the methods used to achieve that result.Hair typically grows all over the human body during and after puberty. Men tend to have more body hair than women. Both men and women tend to have hair on the head, eyebrows, eyelashes, armpits, pubic...

 by mechanically grasping multiple hairs simultaneously and pulling them out. The way in which epilators pull out hair is similar to waxing

Waxing

Waxing is a method of semi-permanent hair removal which removes the hair from the root. New hair will not grow back in the previously waxed area for two to eight weeks, although some people will start to see regrowth in only a week. Almost any area of the body can be waxed, including eyebrows,...

 of the epidermis. Aside from the spring in early spring-type epilators, there are no parts in epilators that require regular replacement. Epilators come in corded, rechargeable and battery operated designs.

Epilation can be painful to some people because, as with waxing, it involves pulling hair out of the roots. Because of the pain involved being particularly bad on the first epilation of an area, some people prefer to have the area professionally waxed first, then use epilation to remove regrowth.

Spring type

The first type of epilator was the original Epilady released in Israel in 1986. The design incorporated a coil spring

, which was bowed into a curve such that the coils on one side of the spring were squeezed tightly together while on the other side the coils were spread apart. The motor in the epilady rotated the spring, causing it to flex as it rotated. Moving the rotating spring across the skin caused the hairs to be caught up in the spring and pulled out the hair.

Because the springs flexed continuously, they were subject to occasional failure and were sold separately as a replacement part.

Today, there are manual epilators designed for the face depilation, depilating spring, that do not use a power supply; such as the Bellabe and Epispring This design consists simply of a coil spring with 2 handles. The spring is then bowed into a curve and placed upon the unwanted facial hair whilst turning the handles. This caused the hairs to be caught between the coils of the springs and pulled out.

The Remington

Remington Products

Remington Products, commonly known as simply Remington, is a worldwide personal care corporation which manufactures razors , epilators, and haircare products for both men and women. It is a subsidiary of Spectrum Brands.-History:...

 Lady Remington Smooth and Silky was designed to operate in a similar way to the spring type Epilady, except that a series of metal discs were used instead of a spring. It was the subject of extensive patent litigation in Europe

Europe

Europe is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally 'divided' from Asia to its east by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways connecting...

 due to a conceptual similarity to the spring type epilator.

The failure of Epilady to defeat Remington in the patent litigation effectively opened the door for other manufacturers to produce designs based upon rotating discs.

Tweezer type

The rotating disc design has been refined such that, in modern designs, the plates are no longer complete discs. The head of a modern epilator incorporates a series of metal plates mounted in a plastic housing. The ends of the plates may be exposed at one or both sides of the housing. As the head rotates, the tips of the plates move together and apart once per revolution. This creates a tweezing effect, where the hair between the plates when they close is pulled as the plates rotate away from the skin, then released as the plates separate. This allows a continuous cycle of gripping, pulling, extracting and discarding the hair as the epilator is moved across the skin.

Depending upon the strength and brittleness of the hair, some may snap off rather than being pulled out. Because those hairs snap off just above the skin surface, they can look somewhat like stubble from shaving

Shaving

Shaving is the removal of hair, by using a razor or any other kind of bladed implement, to slice it down to the level of the skin. Shaving is most commonly practiced by men to remove their facial hair and by women to remove their leg and underarm hair...

, but are far more sparsely spread because the other hairs have been pulled out entirely. As with waxing, because of the phases of growth that occur with hair, there is not as much regrowth following the first epilation. Regular epilation of regrowth is less painful than the initial epilation and the number of broken off hairs diminishes with regular epilation.

There are now numerous brands of tweezer type epilator available. Even Epilady discontinued their spring type and now produce a variety of tweezer type models.
