Are you worried about losing your precious locks? Losing hair is a common concern that affects both men and women. It often causes distress and affects self-esteem. In this quest to find an effective solution to promote hair growth and combat hair loss, laser hair caps and helmets have emerged as a potential remedy. But do laser caps work for hair loss treatment? Do they really grow hair?
Yes, laser caps do work for hair loss treatment. They utilize low-level laser therapy (LLLT), also known as red light therapy, to stimulate hair follicles and promote hair growth by enhancing blood circulation and cellular activity in the scalp. This process encourages hair follicles to move from the resting phase to the growth phase, resulting in thicker and fuller hair over time.
Numerous clinical studies and user reports have shown that consistent use of laser caps can lead to noticeable improvements in hair density, especially for those with mild to moderate hair loss. While individual results may vary, laser caps are considered a safe and non-invasive option for promoting hair growth and managing hair thinning.
In this blog, we've explained how laser hair growth caps and helmets work along with the science behind it. You'll also get to learn about their functionality, benefits, considerations, and efficacy, offering you a comprehensive understanding of their potential in addressing hair loss concerns.
What Exactly are Laser Hair Caps?
Laser hair caps, also known as laser caps or laser helmets, are wearable devices designed to stop hair loss and stimulate hair regrowth. These caps/helmets employ a technology called low-level laser therapy (LLLT), which involves using red light at a low intensity to stimulate the hair follicles on the scalp. The objective is to enhance blood circulation to the follicles, potentially resulting in thicker and fuller hair. These devices are widely promoted as a treatment for male pattern baldness and an alternative to medications like minoxidil and finasteride.
While the efficacy of laser caps on hair restoration varies from person to person, some individuals have experienced significant hair growth and improvement in hair density. It is a non-invasive method of stimulating hair growth and can be used in combination with other hair loss treatments. However, to achieve the potential benefits, consistency and adherence to the recommended treatment schedule are important.
How Do Laser Caps Work for Hair Loss Treatment?
Laser caps use a technology called low-level laser therapy (LLLT) to stimulate hair growth and slow hair loss. These caps contain low-power lasers that emit red light wavelengths, which penetrate the scalp and are absorbed by hair follicles.
The absorbed light energy is believed to stimulate cellular activity within the follicles by increasing the production of adenosine triphosphate (ATP), the energy source for cells. This boost in cellular energy promotes hair follicle function, encouraging hair follicles to transition from a resting phase to an active growth phase. Additionally, LLLT may improve blood circulation in the scalp by causing vasodilation, which increases the delivery of oxygen and nutrients essential for healthy hair growth.
While laser caps do not affect the hormone DHT (dihydrotestosterone), which is a primary cause of male pattern baldness, they work through a different pathway to enhance follicle health and support hair regrowth. Clinical studies have shown that consistent use of laser caps can lead to increased hair density and thickness, especially in individuals with mild to moderate hair thinning.

How Often Should You Use Laser Helmet/Cap?
The frequency of use for your laser helmet or cap depends on the specific model. Some recommend using the laser hair device daily for 6 minutes, while others recommend using it 3-4 times a week. For example, it is recommended to use the Theradome Pro LH80 laser helmet for 20 minutes twice a week. This means you would wear the helmet for 40 minutes each week.
On the other hand, if you have the Theradome Evo LH40, the recommended usage is 20 minutes, four times per week. This totals 80 minutes of usage per week. Following these guidelines ensures that your laser hair growth helmet or cap works effectively giving your hair the best opportunity to benefit from the treatment.
What Are the Benefits of Laser Hair Caps or Helmets?

Laser hair caps have worked to improve hair density and overall hair health. Here are some potential benefits associated with using laser caps or helmets for hair loss treatment:
Stimulating Hair Growth: The lasers in the helmet stimulate hair follicles, potentially promoting new hair growth. The low-level lasers shine light on the scalp and aim to energize the hair follicles. This light energy helps wake up follicles that have become weak or dormant.
Reducing Hair Loss: Low-level laser therapy (LLLT) may help in slowing down the process of hair loss.
Convenience: As a wearable device, laser hair caps are convenient and easy to use in the comfort of your home.

Can You Combine Laser Cap Therapy with Other Hair Loss Treatments?
Yes, laser caps can work with other treatments to treat hair loss, often leading to better results. The light therapy is non-invasive and safe for most people. So it can be added to your current treatment plan. Laser caps use low-level laser technology that provides ongoing stimulation to hair follicles and can be safely used alongside topical treatments like minoxidil or prescription medications such as finasteride. Using laser treatments, medications, special shampoos, supplements, or procedures can give better results.
Meanwhile, the other treatments target hair loss in their unique ways. Together, these combined approaches address thinning hair problem more effectively. They work to slow hair shedding, stimulate follicles, and improve hair growth.
Do Laser Hair Caps Have Side Effects?
Laser hair growth caps are generally considered safe for most people, with very few reported side effects. An evidence-based review published in 2016 evaluated 21 relevant studies on low-level laser therapy (LLLT) devices for hair growth and concluded that those devices are safe and effective for both male and female pattern hair loss. However, some users might experience mild discomfort or irritation on their scalp, especially when first starting treatment. This can include a slight tingling sensation, warmth, or temporary redness, but these effects usually go away quickly.
In rare cases, people with very sensitive skin might have a mild headache or scalp itchiness. It's important to note that laser caps don't use harmful radiation and are designed to be gentle on your scalp. Still, it's always a good idea to follow the instructions carefully and start with shorter sessions to see how your scalp reacts.
