Laser Hair Removal - What you need to know

If you've ever struggled with unwanted hair and are tired of constantly having to shave or wax, then you've come to the right place. In this blog, we will be discussing everything you need to know about laser hair removal, from what it is and how it works, to its benefits and potential side effects.


Laser hair removal is a popular and effective method for getting rid of unwanted hair permanently. It works by using laser technology to target hair follicles, destroying them and preventing regrowth. This means you can say goodbye to the endless cycle of shaving or waxing and enjoy smooth, hair-free skin for longer periods of time.


Overall, laser hair removal is a scientifically driven method that utilizes the principles of light absorption and heat transfer to selectively target and damage hair follicles, providing a long-lasting solution for unwanted hair growth. Laser hair removal is based on the principle of selective photothermolysis, which involves using a specific wavelength of light to target and heat specific structures in the skin.


In the case of laser hair removal, the target structures are the pigment molecules (melanin) in the hair follicles. The laser used in the procedure emits a concentrated beam of light that is absorbed by the melanin in the hair shaft and follicle. As the melanin absorbs the light energy, it is converted into heat, which damages the hair follicle and inhibits further hair growth.


The success of laser hair removal depends on several factors, including the contrast between the color of the hair and the color of the surrounding skin. The greater the contrast, the more effective the treatment will be, as the laser is better able to target the hair follicles.


During the procedure, the laser device is guided over the treatment area, and short bursts of laser energy are delivered to the hair follicles. The heat generated by the laser damages the follicles, disrupting their ability to regrow hair.

It's important to note that laser hair removal typically requires multiple sessions to achieve optimal results since hair grows in cycles and not all follicles are actively producing hair at the same time. This is why multiple treatments spread out over several weeks or months are necessary to target all the hair follicles effectively.


We understand that safety is a concern for many people considering laser hair removal, so we will dedicate a section of our blog to discussing the potential side effects and risks associated with the procedure.


Laser hair removal is generally considered to be a safe procedure when performed by a qualified and experienced professional. However, as with any medical or cosmetic treatment, there are potential risks and side effects to be aware of. The most common side effects of laser hair removal include temporary redness, swelling, and skin irritation in the treated area. These usually subside within a few hours or a few days after the treatment. Applying a cool compress or using over-the-counter creams recommended by Cotswolds Laser Clinic can help alleviate any discomfort.



To further ensure the safety of the procedure, we will conduct a thorough consultation prior to the treatment. They should take into account your medical history, assess your skin type, discuss any medications you are taking, and explain the potential risks and benefits specific to your situation. During the consultation, it's also vital to disclose any existing skin conditions, such as active infections, open sores, or a history of keloid scarring, as these may impact the suitability of laser hair removal.


Before Laser Hair Removal:

1. Avoid sun exposure: It's important to avoid sun exposure, tanning beds, and self-tanning products for at least four weeks before your laser hair removal treatment. Sun exposure can make your skin more sensitive to the laser and increase the risk of complications or side effects.

2. Shave the treatment area: Shave the area you are getting treated one to two days before your appointment. This ensures that the laser energy is focused on the hair follicles rather than the hair above the skin's surface.

3. Avoid waxing, plucking, or threading: Do not wax, pluck, or thread the hair in the treatment area for at least four weeks before your laser hair removal session. These hair removal methods remove the hair from the root, which is necessary for the laser to target the follicles effectively.

4. Cleanse the skin: On the day of your appointment, make sure to clean the treatment area thoroughly and remove any lotions, creams, or oils. This will help the laser penetrate the hair follicles more effectively.


Following their instructions for before and aftercare, you can minimize the risks and achieve safe and effective results.


After Laser Hair Removal:

1. Protect your skin from the sun: After laser hair removal, your skin will be more sensitive to sunlight. Apply a broad-spectrum sunscreen with SPF 30 or higher to the treated area and avoid sun exposure for at least two weeks post-treatment.

2. Avoid hot showers and saunas: For the first two days following your treatment, avoid hot baths, showers, saunas, or any activities that can cause excessive sweating. These can irritate the treated skin and increase the risk of complications.

3. Avoid irritants and exfoliation: For a few days after your treatment, avoid using any harsh or irritating skincare products, such as scrubs, exfoliants, or retinoids. These can further irritate the skin.

4. Apply soothing creams or ice packs: If you experience any redness, swelling, or discomfort after laser hair removal, you can apply a cool compress, ice pack, or aloe vera gel to soothe the treated area.

5. Avoid waxing or plucking: During your laser hair removal treatment series, avoid any hair removal methods that remove the hair from the root, such as waxing or plucking. These can disrupt the hair growth cycle and affect the effectiveness of the laser treatment.

6. Attend follow-up sessions as recommended: Laser hair removal typically requires multiple sessions to achieve optimal results. Follow your provider's recommended treatment schedule to ensure long-lasting hair reduction.

Remember, it's crucial to consult with your specific provider for personalized before and aftercare instructions based on your skin and hair type, as well as the laser system being used.


There are several myths and misconceptions surrounding laser hair removal. Let's debunk some of the most common ones:


Myth 1: Laser hair removal is painful.

While laser hair removal may cause some discomfort, it is generally well-tolerated by most individuals. The sensation can vary from person to person, with some describing it as a rubber band snap or a warm sensation on the skin. For your comfort we use cool techniques to minimize any discomfort during the procedure.

Myth 2: Laser hair removal is only for certain skin and hair types.

Advancements in laser technology have made it possible to treat a wide range of skin tones and hair colors. While it is true that certain laser systems are more effective on specific combinations of skin and hair, professionals can typically tailor the treatment to meet individual needs.

Myth 3: Laser hair removal provides permanent hair removal.

Laser hair removal offers long-term hair reduction but is not guaranteed to result in permanent hair removal. Multiple treatment sessions are usually necessary to achieve desired results, as hair grows in cycles and the laser can only effectively target hair in the active growth phase.

Myth 4: Laser hair removal can cause more hair to grow.

Laser hair removal is designed to reduce hair growth, not stimulate it. In some cases, individuals may initially experience a temporary shedding of treated hair, but this is part of the normal hair growth cycle. With proper treatment, laser hair removal can lead to long-term hair reduction.

Myth 5: Laser hair removal works equally well for everyone.

The effectiveness of laser hair removal can vary based on factors such as hair color, skin color, hair thickness, and hormonal influences. Some individuals may achieve better results than others. It is crucial to have a consultation with a member of our team to assess your specific situation and determine the most appropriate treatment plan.
