The Ultimate Guide to Laser Hair Removal: All Your Questions Answered

Are you still shaving or waxing in 2024? It may be time to ditch the razor and switch to laser.


If you haven’t switched to laser hair removal yet because you’re not quite sure how it works, or if it’s right for you, or if it’s even affordable we’re here to answer your questions.

In recent years, laser hair removal has become increasingly popular as a convenient and effective method of achieving smooth, hair-free skin. But what exactly is it and how does it work? In this comprehensive guide, we’ll explore everything you need to know about this innovative cosmetic procedure.

What is laser hair removal?

Laser hair removal is a non-invasive cosmetic procedure that uses concentrated beams of light to target and remove unwanted hair from various parts of the body. It works by targeting the pigment in the hair follicles, heating them to damage the follicle and inhibit future hair growth. This results in long-lasting hair reduction or removal.

How does laser hair removal work?

During a laser hair removal session, a handheld device is used to deliver pulses of laser light to the treatment area. The pigment in the hair absorbs the light, which then travels down the hair shaft and into the follicle. The heat from the laser damages the follicle, preventing further hair growth.

What are the benefits of laser hair removal?

  • Effectiveness: Most patients experience permanent hair reduction after a series of sessions.
  • Convenience: Laser hair removal offers a long-term solution to unwanted hair, reducing the need for frequent shaving or waxing. Imagine rarely needing to shave again! Just throwing on whatever you want to wear without having to consider hairy legs or underarms.
  • Precision: Laser hair removal targets specific areas, leaving surrounding skin undamaged.
  • Speed: Each pulse of the laser takes only a fraction of a second and can treat multiple hairs at once.

What are the other benefits of laser hair removal?

While laser hair removal is primarily sought after for its ability to provide long-lasting hair reduction and smooth skin, there are several lesser-known benefits that individuals may not be aware of. These benefits go beyond mere aesthetics and can significantly enhance one’s quality of life. Here are some of the lesser-known benefits of laser hair removal:

  1. Reduction of ingrown hairs:

Ingrown hairs occur when hair curls back or grows sideways into the skin after removal, leading to irritation, redness, and even infection. Laser hair removal targets the hair follicle, reducing the likelihood of ingrown hairs by inhibiting hair growth. This can provide relief for individuals prone to ingrown hairs, particularly in areas like the bikini line, underarms, and face.

  1. Improvement in skin texture:

In addition to removing unwanted hair, laser hair removal can also improve the texture and appearance of the skin. The laser energy stimulates collagen production, which helps to tighten and smooth the skin over time. This can result in a more youthful and radiant complexion, particularly in areas where hair growth has caused roughness or unevenness.

  1. Prevention of body odour:

Excessive body hair in areas like the underarms and groin can trap sweat and bacteria, leading to unpleasant body odour. Laser hair removal reduces hair density in these areas, making it easier to maintain personal hygiene and reducing the risk of body odour. This can be especially beneficial for individuals who are physically active or live in warmer climates.

  1. Enhanced confidence and self-esteem:

Unwanted hair growth can be a source of embarrassment and self-consciousness for many individuals, impacting their confidence and self-esteem. Laser hair removal provides a long-term solution to unwanted hair, allowing individuals to feel more comfortable and confident in their appearance. This boost in self-esteem can have positive effects on various aspects of life, including social interactions, relationships, and career opportunities.

  1. Time and cost savings in the long run:

While laser hair removal may require an upfront investment of time and money, it can lead to significant savings in the long run. Unlike temporary hair removal methods like shaving, waxing, or threading, which require regular maintenance and expenses, laser hair removal offers long-lasting results with minimal upkeep. Over time, the cumulative saving on cost and time can be substantial, making it more cost-effective than other methods in the long-run.

  1. Reduction of skin discolouration:

Chronic irritation from shaving or waxing can lead to skin discolouration, particularly in individuals with darker skin tones. Laser hair removal eliminates the need for these abrasive hair removal methods, reducing the risk of post-inflammatory hyperpigmentation and other forms of skin discolouration. This can result in a more even and uniform skin tone, enhancing the overall appearance of the skin.


Preparation Tips Before Your Laser Hair Removal Appointment


Preparation Tips Before Your Laser Hair Removal Appointment

Preparing properly before your laser hair removal appointment can help ensure optimal results and minimise any potential discomfort or side effects. Here are some essential steps to take before your treatment:

  1. Avoid sun exposure:
  • Direct sun exposure can increase the risk of complications during treatment, such as skin irritation or pigmentation changes. It’s crucial to avoid excessive sun exposure for at least two weeks before your appointment – this includes from sunbathing and tanning beds.
  1. Shave the treatment area:
  • The targeted area should be cleanly shaved a day or two before your appointment. This ensures that the laser energy is focused on the hair follicle rather than the surface of the hair, maximising the effectiveness of the treatment.
  1. Avoid waxing, plucking, or depilatory Creams:
  • Refrain from waxing, plucking, or using depilatory creams on the treatment area for at least four to six weeks before your appointment. These methods remove the hair follicle, which is necessary for the laser to target effectively. Stick to shaving in the weeks prior to undertaking laser hair removal.
  1. Skip certain skincare products:
  • Avoid using skincare products containing retinoids, alpha hydroxy acids (AHAs), beta hydroxy acids (BHAs), or other exfoliating agents for at least a week before your appointment (if treating facial hair). These ingredients can increase skin sensitivity and the risk of irritation during laser treatment.
  1. Inform your practitioner:
  • Inform your practitioner about any medications you’re taking, including topical skincare products and supplements. Certain medications, such as antibiotics or photosensitising drugs, may increase the risk of side effects or interfere with the effectiveness of the treatment.
  1. Wear comfortable clothing:
  • Choose loose, comfortable clothing to wear to your appointment, especially if you’re treating larger areas of the body. Tight clothing may cause irritation or discomfort immediately after the treatment.
  1. Arrive clean and fresh:
  • Ensure that the treatment area is clean and free of any lotions, oils, makeup, or deodorants before your appointment. Clean skin allows for better absorption of the laser energy and reduces the risk of adverse reactions.

By following these preparation tips, you can help maximise the effectiveness of your treatment and minimise the risk of complications. If you have any questions or concerns about preparing for your appointment, don’t hesitate to consult with your practitioner for personalised guidance.

What to Expect During Treatment

Before undergoing laser hair removal, it’s essential to consult with a qualified practitioner who can assess your suitability for the procedure and discuss your expectations. At HC MedSpa, you must book a free patch test if you have not had laser hair removal with us before.

  • Procedure: The practitioner will apply a cooling gel to the skin to protect it and ensure the laser’s effectiveness. You’ll be given protective eyewear, and the laser will be adjusted to your specific skin and hair type.
  • Sensation: You may feel a slight tingling or stinging sensation during the procedure, but many patients find it tolerable. This is especially reduced by choosing a clinic that uses Soprano technology rather than Candela. 
  • Aftercare: After the session, in rare cases you may experience redness or swelling in the treated area, which usually subsides within a few hours. You’ll need to avoid sun exposure and certain skincare products for a few days following treatment. The practitioner will advise you further on this at the end of your appointment.

Laser Hair removal before and after


How many sessions of laser hair removal will I need?

The number of sessions required varies depending on factors such as hair colour, thickness, and the area being treated but most people need multiple sessions spaced several weeks apart to achieve optimal results. This is why most clinics recommend a course of at least six sessions to begin with. After the initial treatment regimen, periodic maintenance sessions may be required to sustain the results.

Is laser hair removal permanent?

Laser hair removal offers long-term hair reduction, but it is not always permanent. Some hair may eventually regrow, although it tends to be finer and lighter.

How many sessions are needed for laser hair removal?

The number of sessions required varies depending on the area treated, hair type, and skin type. Typically, 6-8 sessions are needed for optimal results.

Does laser hair removal hurt?

The sensation of laser hair removal is often described as similar to a rubber band snapping against the skin. Pain levels vary based on individual pain tolerance and the area being treated. At HC MedSpa however, we use the latest technology to minimise pain – in-fact our process is virtually pain-free!

Is laser hair removal safe?

When performed by a trained professional using FDA-approved equipment, laser hair removal is considered very safe for most skin types. However, there are some potential risks and side effects, including skin irritation, pigmentation changes, and very rarely, blistering or scarring. It’s crucial to follow the practitioner’s instructions for before and aftercare to minimize these risks.

Can laser hair removal be done on any skin type?

Modern laser technology has made it possible to treat a wide range of skin types. However, it’s generally most effective on individuals with light skin and dark hair. That said, here at HC MedSpa, we use Soprano Titanium laser hair removal which is more effective on darker skin tones than most other devices. 

How much does laser hair removal cost?

The cost varies depending on the area treated, the number of sessions needed, and the type and location of the clinic. At HC MedSpa we aim to keep our prices competitive against other high-street prices while also factoring in our more advanced technology and luxury clinics. We believe luxury should still be affordable so we strive to provide a great client experience with a sense of pampering and wellbeing while you get your treatments done. We do also offer 0% finance options to spread the cost for our clients. For our latest special offers on laser hair removal click here.

What are the main types of laser hair removal technology?

Laser hair removal technology has evolved significantly over the years, leading to the development of various types of lasers, each with its unique characteristics and benefits. The main types include:

  1. Alexandrite Laser:
  • The Alexandrite laser emits a wavelength of 755 nanometers, making it highly effective for targeting melanin in the hair follicle. It is known for its fast treatment speed and is particularly suitable for individuals with light to olive skin tones. 
  1. Diode Laser:
  • Diode lasers emit wavelengths ranging from 800 to 810 nanometers, making them versatile and effective for various skin types and hair colours. They penetrate deeper into the skin, targeting the hair follicle while minimising damage to surrounding tissues. Diode lasers are known for their precision and efficacy, making them suitable for both small and large treatment areas.
  1. Nd:YAG Laser:
  • The Nd:YAG laser emits a longer wavelength of 1064 nanometers, making it suitable for individuals with darker skin tones and finer hair. It has a deeper penetration depth, allowing it to target hair follicles effectively while minimising the risk of damage to the epidermis. Nd:YAG lasers are often used for hair removal on areas with darker skin, such as the face, underarms, and bikini line.
  1. Ruby Laser:
  • The Ruby laser emits a wavelength of 694 nanometers, making it ideal for individuals with fair skin and dark hair. While it is less commonly used than other types of lasers due to its limited effectiveness on darker skin tones, the Ruby laser can provide excellent results for those with lighter skin and hair colours.
  1. Soprano (Diode Technology):
  • Soprano is a state-of-the-art system that combines diode technology with an innovative cooling mechanism. It delivers low fluence, repetitive laser pulses to gradually heat the hair follicles while keeping the skin cool and comfortable. Soprano is suitable for all skin types and offers virtually pain-free treatment with minimal risk of side effects.

Each type of laser hair removal technology has its advantages and limitations, and the most suitable option depends on factors such as skin type, hair colour, and treatment area. It’s essential to consult with a qualified practitioner who can assess your individual needs and recommend the most appropriate laser technology for achieving optimal results.

Why Choose Soprano over Candela Technology?

When considering laser hair removal, you may encounter different technologies and brands offering similar results. Two prominent names in the industry are Soprano and Candela. While both are reputable and effective, there are distinctions that might influence your decision. Here’s why some individuals opt for Soprano technology over Candela:

  1. Pain-Free Experience:
  • Soprano laser technology, specifically Soprano Titanium, utilizes an innovative cooling system that keeps the skin comfortable throughout the treatment. This makes the procedure virtually painless, even on sensitive areas like the bikini line or upper lip.
  • Candela devices typically rely on built-in cooling mechanisms, but some patients may still experience discomfort, especially in areas with denser hair growth or darker skin tones.
  1. Versatility and Speed:
  • Soprano Titanium combines multiple wavelengths and technologies, allowing for comprehensive hair removal across various skin types and tones. Its advanced features enable faster treatment times and greater efficacy.
  • While Candela technology is also effective, Soprano Titanium’s versatility and speed make it a preferred choice for individuals seeking efficient and customizable treatments.
  1. Reduced Risk of Side Effects:
  • Soprano Titanium’s gradual heating method minimizes the risk of skin damage, blistering, or pigmentation changes, even on tanned or darker skin.
  • While Candela technology is generally safe, the risk of adverse effects may be slightly higher, particularly for individuals with darker skin tones or a history of skin sensitivity.
  1. Long-Term Results:
  • Both Soprano and Candela technologies offer long-lasting hair reduction, but Soprano Titanium’s efficacy in targeting hair follicles of varying depths contributes to more consistent and enduring results over time.
  • Soprano Titanium’s ability to treat finer and lighter hair types effectively also ensures comprehensive and sustainable hair removal outcomes.

While both Soprano and Candela technologies are reputable choices, Soprano’s advancements in pain reduction, versatility, safety, and long-term effectiveness make it a compelling option for many individuals seeking a comfortable, efficient, and enduring solution to unwanted hair. 


Laser hair removal offers a convenient and effective solution for reducing or eliminating unwanted body hair and offers a multitude of benefits beyond simple hair reduction, including the reduction of ingrown hairs, improvement in skin texture, and enhancement of confidence and self-esteem. 

By understanding how the procedure works, what to expect during treatment, and the importance of proper aftercare, you can make an informed decision about whether laser hair removal is right for you. If you’re tired of the constant maintenance of shaving or waxing and want long-lasting results, laser hair removal could be the solution you’ve been looking for.
