Does Laser Therapy For Hair Loss actually work?

When it comes to hair loss treatments, there are myriad options available ranging from medicinal to surgical, and even the use of special hair care products. Among these, laser therapy for hair loss has garnered significant attention in recent years. This contemporary treatment method, also known as Low-Level Laser Therapy (LLLT), uses photons emitted from a laser to stimulate scalp tissues and promote hair growth. However, the question that naturally arises here is – does this treatment genuinely work, and if so, how effective is it? This article aims to delve into the efficacy of laser therapy for hair loss, providing a comprehensive understanding of its potential benefits and limitations.

What is Laser therapy?

Laser therapy for hair loss is a non-invasive procedure that has gained popularity due to its minimal side effects and convenience. It works by increasing blood flow to the scalp, which in turn delivers essential nutrients to the hair follicles, promoting their growth. This method has shown promising results in stimulating hair growth, especially in individuals suffering from androgenetic alopecia or male/female pattern baldness. The treatment is typically administered in a controlled environment, where low-level laser light is directed onto the scalp using a device known as a laser cap or helmet.

Does it really work?

The effectiveness of laser therapy for hair loss has been a contentious topic among experts and users alike. While some studies have shown positive results, others have found minimal to no effect on hair growth. A meta-analysis conducted in 2014 concluded that low-level laser therapy can significantly increase hair density and thickness, with minimal side effects. However, it is worth noting that these results were based on a small number of studies and may not apply to everyone. Additionally, the success of laser therapy seems to vary depending on factors such as the type and severity of hair loss, the individual’s age and overall health, as well as the frequency and duration of treatment.

Potential benefits

One of the main advantages of laser therapy for hair loss is that it is a non-invasive procedure with few or no side effects. Unlike other forms of hair loss treatments such as medication or surgery, laser therapy does not involve any incisions or chemicals, making it a safe option for many individuals. Additionally, the treatment can be done in the comfort of one’s home using handheld devices or wearable caps, reducing the need for frequent visits to a clinic.

Apart from stimulating hair growth, laser therapy has also been shown to improve the condition of existing hair. It works by strengthening hair follicles and increasing blood flow, which can lead to thicker and stronger hair. Some studies have also suggested that laser therapy may help with conditions such as dandruff and scalp inflammation, further promoting healthy hair growth.


Despite its potential benefits, laser therapy for hair loss does have some limitations. The treatment is not suitable for everyone and may be less effective for those with severe or advanced hair loss. It also requires consistent and long-term use for visible results, which may not be feasible for some individuals. Additionally, laser therapy can be quite expensive, with the cost ranging from a few hundred to thousands of dollars depending on the device used and the duration of treatment.

While it may not work for everyone, the treatment has shown positive results in many individuals and is a safe alternative to other forms of hair loss treatments. However, as with any medical procedure, it is essential to consult a healthcare professional before starting laser therapy and to manage expectations realistically. With proper use and under the guidance of an expert, laser therapy can be a valuable tool in combating hair loss and promoting healthy hair growth. Overall, the effectiveness of laser therapy for hair loss may depend on various factors, but it is undoubtedly a treatment worth considering for those struggling with hair loss.
