Understanding Laser Hair Removal: How Does It Work?

Laser hair removal represents a major leap forward in aesthetic and dermatological care, offering a path to long-term hair reduction that is both efficient and effective. This modern treatment promises a reduction in unwanted hair with fewer side effects and longer-lasting results compared to traditional methods like shaving, waxing, or electrolysis.

Laser hair removal has evolved over the years, becoming more sophisticated and accessible to a wider range of skin and hair types. As with any cosmetic treatment, however, it’s essential to understand both its effectiveness and safety. At Skinlogic in Severna Park, MD, our focus is on delivering this advanced service with precision and professionalism, and we want to help you understand how laser hair removal works, its technological evolution, and what one can expect from this treatment. 



The core principle of laser hair removal lies in its use of specialized laser technology to target hair follicles beneath the skin’s surface. Unlike traditional hair removal methods like shaving or waxing that temporarily remove hair at the surface level, laser technology aims to disrupt hair growth at its root. The lasers emit a specific wavelength of light, which is absorbed by the pigment (melanin) in the hair. This absorption turns light energy into heat, effectively damaging the hair follicle and reducing its ability to regrow hair.

This targeted approach makes laser hair removal a more lasting solution compared to conventional methods. It also reduces the risk of common issues associated with shaving or waxing, such as ingrown hairs and skin irritation. The precision of lasers ensures that only the hair follicle is affected, leaving the surrounding skin unharmed.


The interaction between laser light and melanin is central to the effectiveness of laser hair removal treatment. Melanin, the pigment that gives hair and skin its color, is the laser’s target. When the laser light is absorbed by melanin, it’s converted into heat, damaging the hair follicle. The amount of melanin in the hair, along with its density and color, greatly influences the treatment’s success.

Darker hair, which has more melanin, typically responds better to laser hair removal as it absorbs more light energy. Conversely, lighter hair, which contains less melanin, may require more sessions for effective results. Similarly, the contrast between hair color and skin tone plays a crucial role. Ideal candidates for laser hair removal are those with a higher contrast between hair and skin color, as the laser can more easily differentiate and target the hair follicle. Advanced laser technologies, however, have made it possible to treat a wider range of hair and skin types, though the effectiveness and number of sessions required may vary.


  • Alexandrite Laser: Best for light to olive complexions, this laser has a fast repetition rate and a large spot size, making it suitable for treating larger areas.
  • Diode Laser: Effective for light to medium skin, diode lasers offer deep penetration and fast treatment times.
  • Ruby Laser: Ideal for very light skin with dark hair, the ruby laser was the first type used for hair removal. It has a shorter wavelength and is less commonly used today due to advancements in technology.
  • Nd:YAG Laser: This laser is safe for all skin types, including darker skin tones. It has a longer wavelength, which allows for safe treatment with minimal risk of skin pigmentation changes.


The Clarity™II Laser by Lutronic® is our preferred laser hair removal device. This advanced laser stands out for its dual-wavelength technology, combining a long-pulsed 755 nm Alexandrite laser and a 1064 nm Nd:YAG laser. The Clarity II Laser’s ​ability to switch between wavelengths enables it to treat different hair types, from coarse to fine, ensuring a more comprehensive hair removal process. The device is also effective for a wide range of skin types and hair colors, making it adaptable to a broad range of patients. Moreover, features like temperature sensing and advanced skin cooling ensure patient comfort and safety.


  • Initial Consultation: Each session begins with a consultation, where the specific needs and skin type of the patient are assessed. This step is crucial for customizing the treatment for maximum safety and effectiveness.
  • Preparation: Prior to the session, patients are advised to avoid sun exposure for at least two weeks, shave the treatment area 24-48 hours before the appointment, and refrain from plucking, waxing, or using certain skincare products. On the day of the treatment, the targeted area is cleaned, and a numbing gel may be applied. The laser settings are then adjusted according to the patient’s hair and skin type.
  • The Treatment: During the treatment, a handpiece is used to deliver laser pulses to the targeted hair follicles. The Clarity II Laser’s dual-wavelength technology ensures precise targeting, minimizing discomfort and protecting the surrounding skin.
  • Safety Measures: Throughout the session, we employ various safety and comfort measures. This includes skin cooling techniques and real-time temperature monitoring to ensure a comfortable experience while effectively targeting hair follicles.


After the treatment, patients are typically advised to avoid direct sun exposure, apply sunscreen regularly, and use gentle skincare products to soothe the treated area. Following these guidelines helps in maintaining skin health and enhancing the treatment’s effectiveness. Laser hair removal results can vary, but most individuals observe a noticeable reduction in hair growth after just a few treatments. The total number of sessions required typically ranges from six to eight, depending on factors like hair density, color, and the treatment area.

The long-term effect of laser hair removal is a significant decrease in hair growth, with many patients experiencing lasting hair reduction. While some maintenance sessions may be needed, these are generally less frequent over time. Each patient at Skinlogic receives a personalized treatment plan, tailored to their individual hair and skin type, ensuring the best possible results.
