Boosting Hair Growth with Low-Level Light Therapy: What You Need to Know

Hair loss can be a challenging and deeply personal issue. At Tendwell in Denver, we take a holistic, functional medicine approach to uncover the root causes of hair loss and thinning, helping our patients find effective, natural solutions. As part of our commitment to comprehensive care, we stay up-to-date on emerging treatments that show promise for stimulating hair growth. One increasingly popular method is Low-Level Light Therapy (LLLT)—a non-invasive treatment that supports natural hair growth for both men and women. In this guide, we’ll walk you through what to expect from LLLT, covering how it works, available device options, and potential outcomes.

What is Low-Level Light Therapy for Hair Growth?

LLLT uses red light in the 630-690 nm range, which is applied directly to the scalp via a helmet-like device. The light’s energy is absorbed by hair follicles and surrounding tissues, enhancing cellular activity and potentially improving hair density. This process may improve blood flow, increase ATP production (the cell’s energy source), and reduce inflammation and oxidative stress—all of which encourage hair follicles to transition from a resting phase into an active growth phase.

Treatment Details:

  • Energy Output: LLLT devices typically deliver a light fluence of about 1 to 10 joules per cm², with a power density between 3 and 90 milliwatts per cm².

  • Duration and Frequency: Most regimens suggest 15-20 minute sessions, three times a week, for six months to achieve noticeable results.

In-Office vs. At-Home Devices: Which is Right for You?

While both in-office and at-home LLLT devices are available, there are some key differences in power and efficacy:

In-Office Devices: These are generally more powerful than at-home versions, allowing for a higher concentration of red light, which often yields quicker and more pronounced results. Many providers recommend a blend of in-office sessions for intensive initial treatment, followed by at-home sessions for maintenance.

At-Home Devices: Although convenient, at-home LLLT devices tend to be less potent. However, there are at least 30 FDA-approved options available for at-home use, offering patients a viable way to maintain their results between in-office treatments.

FDA-Approved At-Home LLLT Devices for Hair Growth

Several FDA-cleared LLLT devices are available for at-home use, including:

  1. HairMax LaserBand and LaserComb – Handheld devices with varying laser densities, suitable for use three times a week.

  2. iRestore Professional Hair Growth System – Helmet-style device with combined LED and laser light therapy.

  3. Capillus Laser Cap – A wearable cap with different models to suit various levels of hair thinning.

  4. Theradome PRO LH80 – A hands-free helmet that uses 80 medical-grade lasers.

  5. Illumiflow Laser Cap – A cap offering coverage for different areas of the scalp with 272 lasers.

These devices offer flexible, at-home options but tend to be most effective when used consistently over months.

Understanding Efficacy: What Does the Research Say?

Clinical trials support the effectiveness of LLLT for hair growth. For example, in a 16-week randomized controlled trial involving 60 participants, those treated with LLLT had an increase of 42 hairs per cm² compared to their baseline, with a 7.5-micrometer increase in hair thickness. This study used 655 nm light for 25-minute sessions every other day, highlighting that consistent treatment over time can yield measurable results.

Costs and Time Commitment for LLLT

In-Office Treatments: Expect to pay between $100 and $500 per session. With three sessions per week, that could mean $300 or more per week. Although pricier, in-office treatments come with professional supervision and higher power output.

At-Home Devices: These range from $200 to $2,000, depending on the power and design. Though the initial investment is substantial, at-home devices can offer a cost-effective, long-term option for ongoing hair maintenance.

Time-wise, most patients spend around three hours weekly on treatment, especially in-office. However, at-home devices provide the flexibility to fit sessions into a personal schedule, which can be a significant benefit for busy individuals.

Recommendations: Choosing the Right Device for You

If you're considering an at-home device, it’s wise to invest in the most powerful and effective option available, as higher power generally leads to better outcomes. For those who prefer professional oversight, a combination of in-office treatments with at-home maintenance may offer the best results.

Ultimately, LLLT represents an exciting, non-invasive option in the world of hair restoration. Consistency and patience are key, and with the right treatment plan, you can expect to see fuller, healthier hair over time.

LLLT is a commitment, both in terms of time and cost, but for many, it’s a worthwhile investment in regaining confidence and addressing hair loss naturally.
