Break the tedious cycle of shaving, waxing, and dealing with skin irritation and disappointing results that come with traditional hair removal methods. Laser treatment for hair removal is changing the game in tackling unwanted hair, providing both men and women effortlessly smooth skin.

Laser hair removal stands out for its precision, targeting dark, coarse hairs while preserving the skin around them. The procedure is a liberating choice that saves time, sidesteps the inconvenience of manual hair removal, and solves unwanted hair problems in the long term. In our latest blog, we delve into the science behind laser treatment for hair removal and give a walkthrough of what to expect.

Removing Unwanted Hair With Laser Precision

At the heart of laser hair removal is a process that uses precision technology to deter our body’s natural hair growth cycles. The method hinges on selective photothermolysis, which essentially means using light to heat and destroy specific targets—in this case, hair follicles. 

Lasers, finely tuned instruments of light, zero in on the melanin within hair follicles. Once the laser’s light is absorbed by the melanin, it transforms into heat. This heat then becomes the catalyst for the follicle beneath the skin’s surface—disrupting its ability to sprout new hair.

However, hair’s natural life cycle plays a crucial role in the effectiveness of this treatment. Hair follicles cycle through periods of growth, dormancy, and shedding. Lasers are most effective against hair in its growth phase when melanin concentration is at its peak, necessitating several sessions to catch each follicle in its vulnerable stage.

The ultimate goal is to apply enough heat to the follicle to put an end to hair growth, or at least significantly reduce the follicles’ ability to grow hair back. Some resilient strands may survive or eventually regrow, but they’re typically finer and less noticeable. Laser hair removal may not be an absolute promise of permanent removal for everyone, but rather it’s a highly effective long-term reduction strategy that outshines other methods.

Types of Laser Treatments For Hair Removal 

Laser hair removal treatments require customisation to address the diverse characteristics of hair and skin in different body areas. Selecting the appropriate laser type is critical for optimising both the efficacy and safety of the treatment for various skin tones and hair textures. Here’s a breakdown of the laser technologies available and their application for specific body parts:

Alexandrite Laser is effective for lighter skin tones, targeting coarse, dark hair with its smaller spot size and lower fluence—the energy delivered per unit area, measured in joules per square centimetre (J/cm²). Higher fluence levels can more effectively target and damage hair follicles for hair removal, but they also increase the risk of side effects, especially on sensitive or darker skin types. 

With a shorter wavelength, this type of laser allows for deep penetration, making it suitable for the underarms, legs, and bikini line, and sometimes the face, depending on skin tone. However, it’s less recommended for darker skin due to potential hyperpigmentation risks.

Meanwhile, Nd:YAG Laser provides a longer wavelength, which is safer for darker skin tones, minimising side effects. It can effectively treat both coarse and fine hair, making it a versatile option for areas like the arms, back, and facial hair. More sessions may be required for achieving optimal results compared to the Alexandrite laser.

Diode Laser covers a wider range of wavelengths, accommodating a variety of skin tones and hair types. Its fast repetition rate makes it ideal for treating large areas such as the legs, back, and chest, effectively managing different hair thicknesses.

On the other hand, GentleMax Pro™ by Candela™ combines 755 nm Alexandrite and 1064 nm Nd:YAG lasers, offering a dual-wavelength solution that caters to all Fitzpatrick skin types. This platform is designed for high-performance hair removal, providing quick, effective treatments for a broad spectrum of skin and hair concerns, including pigmented and vascular lesions.

It’s important to consult with a qualified professional to determine the most suitable treatment for specific needs and skin types. 

Different lasers work better on some than others; for example, there is a wide range of coloured hairs that can make it difficult for certain machines to achieve optimal results. Be sure to ask about the types of laser devices used at the clinic, as well as pros and cons.

What to Expect From Your Laser Hair Removal Journey

A typical laser hair removal session involves preparation, treatment, and post-treatment phases. During the preparation stage, a qualified practitioner will ask you about your goals and medical history. They will also assess your skin and hair type and suggest the most suitable laser type and setting for you. Then, the treatment area will be cleansed and possibly numbed with a topical cream, especially for sensitive areas. You and the technician will wear protective eyewear to shield your eyes from the laser light.

During the procedure, the technician will use a handheld laser device to deliver precise pulses of light onto the treatment area. You might feel a snapping sensation or a warm prickling feeling. The discomfort level varies depending on your individual sensitivity and the laser settings used. The session duration can range from a few minutes for small areas like the upper lip to over an hour for larger areas like the back.

After the treatment is done, you might experience some redness, swelling, or mild discomfort for a few hours after the treatment. These usually subside within a day or two. Treated hair might begin to shed within a week or two, but it’s important not to pluck or tweeze these hairs. Let them fall out naturally.

As mentioned earlier, laser hair removal works best during the hair’s growth phase. Since hair follicles grow at different rates, multiple sessions spaced 4-8 weeks apart are typically needed for optimal results. The exact number of sessions will vary depending on your individual factors and treatment goals.

Remember: Communication is key! Don’t hesitate to ask any questions or voice any concerns you might have throughout the process.
