Benefits of LLLT for Hair Regrowth


As an Aesthetic Director with over a decade in the industry, I’ve seen many clients concerned about hair loss. They often ask about laser treatments. I’ve learned a lot through my experiences and research. I want to share this knowledge with you.

Laser treatment for hair loss is a topic many are curious about. It uses light to boost hair growth. In this article, I will explain how it works, its benefits, and what to expect. This guide will be clear and easy to understand.

I’ve made sure to keep things simple and to the point. I hope it helps you understand laser treatment for hair loss better.

Based on a study conducted in 2014, low-level laser treatment has been found to be effective and safe for promoting hair growth in both men and women.

Background on Low Level Laser Treatment for Hair Loss

Low-Level Laser Treatment for Hair Growth: An Overview

Based on a study conducted in 2014, low-level laser treatment has been found to be effective and safe for promoting hair growth in both men and women.

Laser Hair Treatment and Hair Growth: Findings from a 2013 Study

A separate research study carried out in 2013 on 41 men between the ages of 18 and 48 revealed that laser hair treatment resulted in a 39% increase in hair growth over a period of 16 weeks.

The Potential of Laser Therapy for Hair Regrowth

In this detailed guide, Wellaholic explores the potential of laser therapy in mitigating hair loss and promoting hair regrowth for both male and female pattern hair loss. With certain treatments, it may be possible to not only slow down or halt thinning hair or related hair loss conditions, but also regrow hair that was previously thought to be permanently lost.

Exercise boosts body health and promotes a strong hair growth cycle. It also increases the blood flow to scalp and promote circulation around the scalp, resulting in better hair growth.

How is laser hair therapy supposed to work? 

Understanding the Hair Growth Cycle

The hair growth cycle comprises three distinct phases: the growth phase (anagen), the resting phase (telogen), and the shedding phase (catagen). Hair loss in androgenetic alopecia is linked to a derivative of testosterone in the skin, known as dihydrotestosterone (DHT). Low-level laser therapy is thought to stimulate blood flow in the scalp and invigorate the metabolism in the catagen or telogen follicles, leading to the production of anagen hair.

The Science Behind Laser Therapy for Hair Regrowth

On a molecular level, the photons from the light act upon an enzyme in the cells called cytochrome C oxidase. This interaction leads to the production of adenosine triphosphate (ATP), which gets converted into cyclic AMP in the hair follicle cells. This triggers energy release and stimulates the metabolic processes necessary for hair growth. Furthermore, the release of nitric oxide from the cells results in improved vascularisation to the scalp, ensuring better nutrient and oxygen supply to the hair roots. Consequently, the excessive build-up of DHT is inhibited.

Simplified Explanation: How Low-Level Light Therapy Promotes Hair Growth

If we were to simplify the explanation, we could compare low-level light therapy to watering plants. In this analogy, our scalp is the plant and the laser represents the water. The scalp absorbs energy from the laser, stimulating hair follicles and enhancing the distribution of blood supply and nutrients. Therefore, low-level light therapy encourages hair regrowth in a similar way that water helps a plant grow.

a study in 2013 showed that LLLT help provided a 39 percent increase in hair growth over a period of 16 weeks for the 41 males ages 18 to 48 in the study

Is there clinical evidence to show the effectiveness of laser treatments for hair loss? 

The Medical Opinion on Low-Level Laser Therapy for Hair Loss

Physicians’ views on the efficacy of low-level laser therapy for hair loss differ. Some medical professionals completely dismiss its usage, while others believe it can offer benefits for both men and women suffering from androgenic alopecia, also known as genetic hair loss. It has also been suggested that low-level laser therapy can aid in the postoperative wound healing process for hair transplant patients, and potentially accelerate hair growth.

Study on Low-Level Laser Therapy Effectiveness

Results from a double-blind, sham device-controlled, randomized multi-centre trial provide evidence-based insights into the effectiveness of low-level laser therapy. The trial involved 110 male participants suffering from Norwood-Hamilton classes IIa-V androgenic alopecia. After 26 weeks of treatment with a laser light comb, these participants displayed a significantly higher increase in mean terminal hair density compared to those in the sham device group.

Methodology and Results of the Laser Therapy Trial

The researchers captured macro photographs of all the subjects’ scalps at the beginning and end of the trial. They used advanced hair counting software to identify the number of normal-sized hairs that grew as a result of using either device. According to the trial, hair growth increased by an average of 19 normal-size hairs per square centimetre in subjects who used laser therapy. Conversely, the number of normal-size hairs decreased by an average of 7 per square centimetre in those using the placebo device.

Low level laser hair therapy (LLLT) is typically administered using a handheld device that emits low levels of laser light onto the scalp

How is low level laser hair therapy administered ?

In my time as an Aesthetic Director, I’ve seen how Low Level Laser Hair Therapy (LLLT) helps many with hair loss. We use a handheld device that emits low-level laser light. We move it over the scalp for about 20 to 30 minutes each session.

The light stimulates hair growth and improves blood flow. Some use a helmet-like device that covers the whole scalp. The number of sessions varies. It depends on the person’s needs and their hair loss. Most people have a few sessions a week for a few months.

Low-Level Laser Therapy (LLLT) is a non-invasive treatment for hair loss that uses low-level lasers or light-emitting diodes (LEDs) to stimulate hair growth. The therapy is thought to work by increasing blood flow and oxygen delivery to the hair follicles, as well as by enhancing cellular metabolism and protein synthesis.

How Does LLLT Treat Hair Loss?

In my role, I’ve seen how Low-Level Laser Therapy (LLLT) helps with hair loss. It uses lasers or LEDs to boost hair growth. These beams increase blood flow and oxygen to hair roots. They also improve cell metabolism and protein building. This process happens when the light reaches the scalp and stimulates the hair roots.

The best part? LLLT is painless and safe. It works well for both men and women with certain types of hair loss. Sometimes, we use it with other treatments for even better results.

Low-level laser therapy (LLLT) is a non-invasive treatment for hair loss that works by stimulating hair follicles and promoting hair growth. Here’s how LLLT treats hair loss or balding:

FeaturesExplanation of How LLLT Treats Hair Loss
Increases blood flowLLLT increases blood flow to the scalp and hair follicles. This increased blood flow delivers more oxygen and nutrients to the hair follicles, which can promote hair growth.
Stimulates hair folliclesLLLT stimulates hair follicles in the resting (telogen) phase to enter the growth (anagen) phase. This can lead to an increase in the number of hair follicles in the growth phase, which can promote hair growth.
Reduces inflammationLLLT can reduce inflammation in the scalp, which can be a contributing factor in hair loss.
Promotes cell growthLLLT promotes cell growth and repair in the scalp and hair follicles, which can promote hair growth.
Energizes hair folliclesLLLT provides energy to hair follicles, which can help them function more effectively and promote hair growth.
Non-invasive and safeLLLT is a non-invasive treatment for hair loss that is generally considered safe. It does not require any incisions or injections, which can minimize the risk of complications. LLLT is associated with few side effects, and there is no evidence to suggest that it carries any long-term risks or complications.
Evidence-based treatmentClinical studies have found LLLT to be a safe and effective treatment for hair loss, particularly for male and female pattern baldness. LLLT has been shown to increase hair density and thickness, and it works by promoting blood flow, stimulating hair follicles, reducing inflammation, promoting cell growth, and energizing hair follicles.
