Laser treatment for hair loss

Pattern baldness, or alopecia, is one of the most prevalent types of male and female hair loss. It affects approximately 85% of men and 40% of women by age 50.

One solution to reduce the effects of alopecia is laser hair loss treatment, a non-invasive and safe procedure where advanced red-light therapy helps to prevent hair fall out and encourage new growth.

Laser for hair loss is a Food and Drug Administration (FDA)-approved restoration option that’s safe, painless, and produces long-lasting and life-changing results.

It helps to reactivate dormant hair follicles that aren’t producing new growth and regenerate them, and is suitable for treating:

  • Male pattern baldness
  • Female pattern baldness
  • Alopecia areata
  • Endocrine alopecia
  • Postpartum hair loss
  • Hair loss as a result of genetic factors
  • Hair loss caused by use of contraceptives
  • Hair loss from chronic diseases (scalp eczema anaemia)
  • To enhance the effects of surgical hair transplants

What is laser hair therapy?

Laser hair regrowth therapy, also referred to as low-level laser therapy (LLLT) or red-light therapy, is a non-surgical hair loss treatment method. It uses medical-grade lasers emitting safe, low-level light onto the scalp to reactivate and stimulate hair follicles. The cells absorb the light photons and encourage them to repair themselves to kick-start the natural hair growth cycle. It can also help to increase blood flow and circulation to the scalp. This is vital as it ensures that more nutrients and oxygen are delivered to the hair follicles, creating a healthy environment for hair regrowth.

Laser treatments for hair growth are one of the most popular and effective solutions for restoration, especially for those who don’t want to undergo surgery or take medication. LLLT can also be used following FUE hair transplants to achieve the best hair restoration results possible. It’s an excellent option for those in the early stages of hair loss or who suffer from mild thinning or receding. Laser hair therapy can also successfully combat common conditions like male and female pattern hair loss. However, laser hair treatments can be less effective in cases of severe hair loss, and we’d suggest enquiring about a FUE hair transplant as an alternative.

How does laser hair treatment work?

Laser hair therapy uses therapeutic pure red lights to penetrate deep into the tissues of the scalp, stimulating blood circulation, cell metabolism, and protein synthesis. This increases the number of red blood cells that deliver vital oxygen and nutrients around the body. The result is a restorative and reparative chain reaction that clears debris from the hair shafts, swells the cortex, and closes the cuticle – leading to a healthier scalp that looks and feels softer, thicker, shinier, and easier to manage.

If LLLT is completed regularly, the laser light strengthens and regenerates the hair roots. This slows or arrests and, in some cases, reverses the degenerative cycle where the hair grows for several years, falls out, and then is not replaced as the follicles are dormant. Once the hair roots are dead, nothing can be done to restore them, so the sooner laser hair treatment is started, the better the hair restoration results are.

Clinical studies also suggest that the cellular and sub-cellular activity resulting from the laser light breaks down dihydrotestosterone (DHT). DHT is a hormone primarily responsible for male and female pattern hair loss; therefore, lower levels of DHT can help decrease the appearance of alopecia conditions.

What’s the process for LLLT?

Here’s a step-by-step overview of what you can expect from a laser hair treatment:

Initial consultation – Before undergoing laser hair therapy, we strongly recommend booking a free consultation with our expert surgeons. During this session, our medical professionals will assess the patient’s scalp and determine the suitability of laser therapy for their specific type of hair loss.


Preparation for treatment – Unlike surgical procedures, laser hair therapy does not require anaesthesia as it is pain-free and non-invasive. However, the patient’s scalp may require preparation to ensure it is clean and ready for treatment.


Application of laser light – Each session typically lasts around 30 minutes, where a laser therapy hood or cap is placed over the patient’s head. These devices are equipped with laser diodes that emit specific wavelengths and frequencies of light, directing low-level light therapy to the entire scalp at once.


Photon absorption – The weak or dormant hair follicles, usually in areas suffering from hair loss, absorb the photons from the laser light. This absorption is critical as it provides the energy needed for these follicles to rejuvenate and return to an active growth phase.


Stimulation of hair growth cycle – The laser light stimulates the hair growth cycle, encouraging the hair follicles to return to an active growth phase from the resting phase.


The patient returns for regular sessions – For the best results, laser hair therapy typically requires multiple sessions over a period of weeks or months. The exact number of sessions and frequency will depend on the individual’s condition and response to the therapy.


Post-treatment care – After each treatment, we provide patients with careful scalp care and maintenance instructions to increase the success of the laser light therapy.


At KSL Clinic, our highly qualified medical professionals carry out each laser hair treatment procedure using industry-approved equipment for maximum efficacy.

What are the benefits of laser hair regrowth therapy?

Here are some of the key advantages of opting for laser hair regrowth therapy:

It’s non-invasive

Unlike surgical hair restoration methods, laser hair therapy is entirely non-invasive. This means there is no need for incisions, sutures, or extractions, making it a particularly appealing option for those seeking a less aggressive approach to hair restoration.

Leaves no scarring

Since the treatment involves no cuts or surgical intervention, there is no risk of any visible scarring on the scalp after the treatment.

Minimal to no recovery time

As laser hair therapy is gentle and non-invasive, no downtime is typically required post-treatment. Patients can usually resume their daily activities immediately after each session, making it a convenient option for those with busy schedules.

It’s safe and painless

Laser hair loss treatment is painless, and patients experience no discomfort during the sessions, which is a significant advantage over more invasive hair restoration techniques.

Benefit from stronger and healthier hair

In addition to promoting new hair growth, laser therapy is known to improve the strength and health of existing hair – unlike surgical hair transplant options. This leads to an overall improvement in hair quality, texture, and thickness.

It’s safe and painless

Laser hair loss treatment is painless, and patients experience no discomfort during the sessions, which is a significant advantage over more invasive hair restoration techniques.

How much does laser hair therapy cost?

It’s difficult to quote a definitive price as each patient’s required laser sessions will vary.

The cost of laser hair therapy depends on the total number of sessions that our surgeons recommend throughout the course of your treatment. The amount of sessions required is determined by the severity of your hair loss, which our experts will review at your initial consultation.

Laser hair therapy FAQs

Is laser hair therapy painful?

No, laser hair therapy is painless, and you won’t feel any discomfort during the treatment. It’s entirely non-invasive, doesn’t require any incisions, and uses a low-level light laser that emits small amounts of energy.

How many laser treatment sessions will I need?

The number of laser treatment sessions you require depends on the extent of your hair loss; more moderate cases may require a prolonged course of treatment, while milder cases may need fewer sessions.

Generally speaking, sessions can be carried out weekly across a 6-12 month course as consistent treatment is needed to see effective results. However, each patient is different, so there is no set number of recommended procedures.

How soon will I see the results of the treatment?

Results from laser hair therapy can vary as each person responds differently, but patients can expect to see improvements from 3-6 months of regular weekly treatment. However, having realistic expectations and understanding that results can take longer is essential.

Is laser hair treatment right for me?

While many people have seen incredible results and regrowth, it’s important to remember that laser hair therapy is best suited for those experiencing the early stages of hair thinning and loss. This includes a receding hairline, general thinning, or pattern baldness.

It is less effective for those with advanced hair loss, so an alternative hair restoration solution may be more suitable. Here at KSL Clinic, we offer FUE hair transplants and PRP injections, which can be a better option.

A consultation with one of our hair restoration specialists can determine which hair restoration treatment is appropriate for you. Book your free consultation today.

When can I go back to work after laser hair regrowth?

One of the biggest advantages of laser hair therapy is that you won’t need to take any downtime after your treatment. You can return to work or your daily activities immediately after each session, as the procedure is non-invasive and non-surgical.

Are there any side effects?

No, laser hair therapy is widely considered safe with minimal risk of side effects. It is an FDA-approved procedure, abides by European standards for safety, and has been carried out in Europe for decades without any known side effects.
