How laser hair removal works ?

Laser hair removal is a popular method of hair removal that has been widely used for several years. This technique involves the use of laser technology to destroy hair follicles, preventing hair growth. In this article, we will explore the history of laser hair removal technology, including the key companies and breakthroughs that have made it a popular choice for people seeking hair removal solutions.

The functioning of laser hair removal

The Basics of Laser Hair Removal

Laser hair removal works by targeting the pigment in the hair follicle, which absorbs the laser energy, destroying the follicle, and preventing further hair growth.

The technology in details

Laser hair removal works by using a laser to target and damage the hair follicle, preventing further hair growth. The laser emits a concentrated beam of light, which is absorbed by the pigment (melanin) in the hair follicle. The light energy is then converted into heat, which damages the follicle and prevents it from producing hair.

Different types of lasers are used, including diode, Alexandrite, and Nd: YAG lasers, which have different wavelengths and are used for different skin tones and hair colors. The ideal candidate for laser hair removal is someone with light skin and dark hair since the laser targets pigment in the hair follicle. However, newer laser technologies have made laser hair removal possible for those with darker skin tones.

During the laser hair removal process, a handheld device is used to deliver the laser energy to the skin. The device emits a cooling spray or uses a cooling tip to minimize discomfort during treatment. The laser is then moved over the skin in a sweeping motion, targeting individual hair follicles.

Laser hair removal is most effective on hair that is in the active growth phase (anagen phase). Since not all hairs are in the active growth phase at the same time, multiple treatments are needed to target all hair follicles. Treatment sessions are typically scheduled several weeks apart to allow time for hair growth and to target hairs in the active growth phase.

Overall, laser hair removal is a safe and effective method of hair removal, with long-lasting results. However, it is important to choose a reputable provider and follow proper aftercare to minimize the risk of side effects.

Advantages and Disadvantages of Laser Hair Removal

The main advantage of laser hair removal is its long-term effectiveness. Unlike other hair removal methods, such as shaving or waxing, laser hair removal can result in permanent hair reduction. It is also relatively painless, and the recovery time is minimal.

However, laser hair removal can be expensive, and multiple treatments are usually required. It can also cause mild discomfort during treatment and may not be suitable for everyone.

Section 6: Safety Concerns and Side Effects

While laser hair removal is generally safe, there are some possible risks and side effects, including skin irritation, redness, and scarring. These can be minimized by choosing a qualified provider, following proper aftercare, and avoiding sun exposure after treatment.

Past and future of laser hair removal technology

The History of Laser Hair Removal

The concept of using lasers for hair removal dates back to the mid-1960s, but it wasn’t until the early 1990s that the first laser for hair removal was developed. This laser, called the Ruby laser, was effective but only worked on those with light skin and dark hair.

Since then, several companies, including Candela Corporation, Lumenis, and Syneron Medical, have developed newer laser technologies, including the Alexandrite and Nd: YAG lasers. These lasers are more versatile and can be used on people with different skin tones.

Current Trends in Laser Hair Removal Technology

The latest advancements in laser hair removal technology include the use of IPL (Intense Pulsed Light) technology and the development of handheld laser devices for home use. These new technologies are making laser hair removal more accessible and affordable.

The future of laser hair removal technology is focused on developing more effective and efficient laser devices that can treat larger areas in less time. There is also a growing interest in using lasers for hair regrowth and as a treatment for hair loss.


In conclusion, laser hair removal technology has come a long way since its inception in the mid-1960s. Today, it is a popular and effective method of hair removal, with several new technologies making it more accessible and affordable. However, it is essential to understand the advantages, disadvantages, and safety concerns associated with laser hair removal and to choose a qualified provider for safe and effective treatment.
