Laser Hair Removal: Everything You Need to Know


Laser hair removal has become increasingly popular for achieving smooth, hair-free skin. It is a non-invasive procedure that uses concentrated beams of light to target and destroy hair follicles. This results in permanent hair reduction in the treated area. Delving into the intricate workings of this technology can provide valuable insights into its effectiveness and longevity. So, if you’re considering laser hair removal as your preferred hair removal method, here’s everything you need to know.

How Does Laser Hair Removal Work?

Laser hair removal operates on the principle of selective photothermolysis. In simpler terms, it targets the melanin pigment present in hair follicles. The concentrated light energy emitted by the laser is absorbed by the melanin, heating and damaging the follicle without affecting the surrounding skin. This process inhibits future hair growth, offering long-term results.

How Many Sessions for Laser Hair Removal?

The number of laser hair removal sessions required varies depending on individual factors such as skin tone, hair colour, and the treatment area. Generally, multiple sessions spaced several weeks apart are necessary to achieve optimal results. On average, most individuals undergo between six to eight sessions, although this number may vary depending on the individual’s hair growth patterns and desired results.

How Long Do Sessions Take?

Each laser hair removal session typically lasts anywhere from a few minutes to an hour, depending on the size of the treatment area. Smaller areas, such as the upper lip or underarms, may require mere minutes, while larger areas, like the legs or back, may take longer to complete.

How Long Does Laser Hair Removal Last?

One of the most enticing aspects of laser hair removal is its long-lasting results. While individual experiences may vary, many enjoy significantly reduced hair growth for months or even years following their treatment regimen. Regular maintenance sessions may be necessary to sustain these results over time.

How Long Between Laser Sessions?

To maximise the effectiveness of laser hair removal, it’s crucial to adhere to the recommended time frame between sessions. Typically, this interval ranges from four to eight weeks, allowing sufficient time for treated hair to shed and new hair follicles to enter the growth phase.

In some cases, certain body areas may have longer hair growth cycles, resulting in a slower response to laser treatments. This is particularly common in the legs or back areas, where hair can take longer to complete its cycle and shed. In these instances, patience and consistency are key. For optimal results, it may require a few additional sessions or a longer time frame between treatments. Your practitioner will be able to assess your individual needs and adjust your treatment plan accordingly.

Choosing the Ideal Hair Removal Laser

Several lasers are used for hair removal, each catering to specific skin types and hair colours. Among the most popular options are Alexandrite, Diode, and Nd:YAG lasers. The Alexandrite laser is often preferred for lighter skin tones, while the Diode or Nd:YAG lasers are better suited for darker skin tones. It’s essential to consult with a trained and experienced practitioner to determine which type of laser will work best for you. Consulting with a qualified practitioner can help determine the most suitable laser for individual needs.

How Much Is Laser Hair Removal?

The cost of laser hair removal varies depending on factors such as the size of the treatment area, the number of sessions required, and the geographic location of the clinic. While upfront costs may seem daunting, many individuals find that the long-term savings outweigh the initial investment. Prices can range from £499 for 8 bikini + 1 area sessions to £1,700 for 8 full body sessions in London.

Preparing for Laser Hair Removal

Preparing adequately to ensure optimal results and minimise the risk of adverse effects is essential before undergoing laser hair removal. This may include avoiding sun exposure, discontinuing certain medications, and shaving the treatment area before each session. It’s also important to discuss any medical conditions or concerns with the clinician beforehand.

The Procedure

During laser hair removal, a concentrated beam of light is directed at the hair follicles, damaging them and inhibiting future growth. The procedure is relatively quick and can be completed in as little as 10-40 minutes, depending on the size of the area being treated. While some individuals may experience discomfort during treatment, many report mild sensations such as tingling or stinging.


Following laser hair removal, proper care of the treated area is essential to minimise any potential side effects. This may include avoiding excessive heat or sun exposure, using moisturisers or soothing creams recommended by the clinician, and keeping the area clean and dry.

Can You Shave After Laser Hair Removal?

Following laser hair removal, it’s common for treated hair to shed gradually over the coming weeks. While shaving between sessions is safe, other hair removal methods, such as waxing or plucking, should be avoided to prevent interfering with the hair follicles targeted by the laser.

Laser hair removal offers a safe, effective, long-lasting solution for unwanted hair. By understanding the intricacies of this technology and adhering to proper treatment protocols, individuals can achieve smooth, hair-free skin and enjoy newfound confidence in their appearance.
