Laser Hair Removal – How Long Does It Last? And Who Should Do It?

In the pursuit of smooth, hair-free skin, laser hair removal is a popular and effective cosmetic procedure. Harnessing the power of concentrated light beams, this non-invasive technique targets unwanted hair with precision. The science behind laser hair removal lies in the absorption of highly concentrated light by the pigment (melanin) in the hair follicles. Once absorbed, this energy transforms into heat, strategically damaging the follicles and curbing their ability to produce future hair growth.

This procedure offers a semi-permanent solution to unwanted hair, providing individuals with a smoother and longer-lasting alternative to traditional hair removal methods. In this blog article, we delve into the intricacies of laser hair removal, exploring its mechanisms, suitability for different skin types, and what individuals can expect from this transformative cosmetic treatment.

Here’s How the Process Generally Works:

Laser hair removal operates on a sophisticated principle where concentrated light, emitted by a laser, is directed onto the targeted area. As the intense light transforms into heat, it precisely damages the follicles, impeding their ability to produce new hair. Since hair grows in distinct cycles, not all follicles are simultaneously in an active growth phase.

Multiple sessions are needed to target hair in different stages of the growth cycle, ensuring a comprehensive and effective reduction in hair growth. This sophisticated technology offers people a semi-permanent solution to unwanted hair, minimising the need for regular maintenance and presenting a modern approach to achieving smoother, hair-free skin. For it to be successful, the process should normally involve:

Steps to Successful Laser Hair Removal



Before undergoing laser hair removal, you should have a consultation with a trained practitioner or dermatologist to determine if you are a suitable candidate for the procedure. Factors such as skin type, hair colour, and medical history may be considered. Zecca has extensive experience in Laser hair removal.

Before the procedure, it’s advisable to avoid sun exposure, as tanned skin can increase the risk of complications. The hair in the treatment area is usually trimmed or shaved to a short length.

Application of Gel or Cooling Device:

A cooling gel or device may be applied to the skin to protect it and to help the laser penetrate the skin.

Laser Treatment:

The laser is then directed at the treatment area. The pigment in the hair follicles absorbs the light, and the energy is transformed into heat. This heat damages the follicles, inhibiting their ability to grow new hair.

Post-Treatment Care:

After the procedure, you may experience some redness and swelling in the treated area, which usually subsides within a few hours to a day. It’s important to follow post-treatment care instructions, including avoiding sun exposure and using soothing creams if recommended.

Multiple Sessions:

Since hair grows in cycles, multiple sessions are usually required to target hair in different growth phases. The number of sessions needed can vary depending on factors such as the individual’s hair type, skin colour, and the specific area being treated

Laser hair removal is commonly used for various areas of the body, including the face, legs, underarms, bikini line, and more. It’s considered a semi-permanent hair reduction method, as it can significantly reduce hair growth, but maintenance sessions may be needed over time.

It’s crucial to have laser hair removal performed by a trained and experienced professional at a credible clinic like Zecca to minimise the risk of side effects and optimise results.

How Often Do You Need Laser Hair Removal?

Laser hair removal is a nuanced process influenced by various factors, and its effectiveness requires a tailored approach involving multiple sessions. The frequency of these sessions is tied to factors such as the specific area being treated, the characteristics of your hair (such as colour and type), and the individual response of your body to the treatment.

Laser hair removal revolves around targeting the hair follicles during their active growth phase. The concentrated light emitted by the laser is absorbed by the melanin in the hair follicles, transforming the light energy into heat. This heat disrupts the follicles’ ability to produce new hair effectively. However, given that hair growth occurs in cycles with distinct phases, not all follicles are actively growing at the same time. As a result, multiple sessions are necessary to address hair in various stages of the growth cycle.

A general guideline for the frequency of laser hair removal sessions is as follows:

  • Face: Typically, sessions are recommended every 4 to 6 weeks.
  • Body (excluding face): Treatment intervals are commonly set at every 6 to 8 weeks.
  • Legs: For the legs, sessions are often spaced every 8 to 10 weeks.

However, it’s crucial to emphasise the individualised nature of laser hair removal. Following the recommendations provided by your dermatologist or Zecca trained medical practitioner overseeing your treatment is essential. They will assess how your body responds to the sessions and make adjustments to the schedule accordingly.

Despite the efficacy of laser hair removal in significantly reducing hair growth, maintenance sessions may be necessary over time to address any regrowth that occurs. Additionally, adherence to pre- and post-treatment care instructions is vital. This may involve avoiding sun exposure before and after sessions and following recommended skincare practices. By maintaining open communication with your practitioner and diligently following their guidance, you can optimise the results and safety of the laser hair removal process.

Who Should Consider Laser Hair Removal?

Laser hair removal is generally considered safe and effective for many people, but its suitability can depend on several factors. It’s important to consult with a qualified practitioner or dermatologist to determine if laser hair removal is the right option for you. Here are some considerations:

Hair and Skin Colour: Laser hair removal is most effective on individuals with a combination of light skin and dark hair. The laser targets the pigment (melanin) in the hair follicles, and the contrast between dark hair and light skin allows for better targeting. People with lighter hair may not be good candidates because the laser may not effectively distinguish between the hair and surrounding skin.

Skin Type: Individuals with darker skin tones may be at a higher risk of pigmentation changes or burns due to the increased melanin in their skin. However, advancements in laser technology have made it possible to safely treat a broader range of skin tones. It’s essential to use appropriate laser systems and settings for different skin types.

Medical Conditions and Medications: Certain medical conditions or medications can affect the suitability of laser hair removal. For example, conditions like polycystic ovary syndrome (PCOS) or hormonal imbalances may impact hair growth, and medications such as isotretinoin (Accutane) can increase the risk of complications.

Hair Growth Stage: Laser hair removal is most effective when targeting hair in the active growth phase. Since hair grows in cycles, multiple sessions are needed to address hair in different stages of the growth cycle.

Expectations and Patience: Laser hair removal provides long-lasting hair reduction but may not result in complete permanent removal. Patience and realistic expectations are important.

Pregnancy: While laser hair removal is generally considered safe during pregnancy, some practitioners may recommend avoiding it, especially in the first trimester, due to limited studies on the effects of lasers on developing foetuses.

It’s crucial to have a thorough consultation with a qualified professional before undergoing laser hair removal. They can assess your individual characteristics, medical history, and expectations to determine if the procedure is suitable for you. Always choose a reputable and experienced practitioner to minimise the risk of complications and achieve the best results. Book in for a consultation with Zecca today!
