Epilator
From Wikipedia, the free encyclopedia
- This article is not about devices intended to permanently remove one hair at a time. Those devices are Electric tweezers.
An epilator is an electrical device used to remove hair by mechanically grasping multiple hairs simultaneously and pulling them out. The way in which epilators pull out hair is similar to waxing. Aside from the spring in early spring-type epilators, there are no parts in epilators that require regular replacement. Epilators come in mains powered, rechargable 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.

[edit] Spring type
The first type of epilator was the original Epilady, released in 1986.[1] 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.[2]
Because the springs flexed continuously, they were subject to occasional failure and were sold separately as a replacement part.
[edit] Rotating disc type
The Remington 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 due to a conceptual similarity to the spring type epilady.
The failure of Epilady to defeat Remington in the patent litigation effectively opened the way for other manufacturers to produce designs based upon the rotating disc design.
[edit] 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 tweezer 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, but are far more sparsely spread because the other hairs have been pulled out entirely. Because ot the phases of growth that occur with hair, there is not as much regrowth following the first epilation, as with waxing. 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.[3]
