Red Light Therapy Touted as Potential Hair Loss Treatment

Experts say consistent usage can help stimulate regrowth, but more research is needed.

Published on Feb. 22, 2026

Hair loss is a common issue, and some experts believe red light therapy could be a potential treatment option. Red light therapy is thought to boost circulation and blood flow to the scalp, bringing nutrients to stimulate new growth. While preliminary research supports this, more studies are needed to fully understand its efficacy. Dermatologists recommend consulting a doctor to diagnose the cause of hair loss and incorporating red light therapy into a comprehensive treatment plan, as consistency is key for seeing results.

Why it matters

Hair loss can be a sensitive and frustrating issue for many people. Finding safe, effective treatments is important, and red light therapy offers a non-invasive option that may help address the problem. As more people look to combat hair thinning and shedding, understanding the potential benefits and limitations of this therapy is valuable.

The details

Red light therapy works by utilizing specific wavelengths of red and near-infrared light to penetrate the skin and stimulate cellular activity. This process is thought to enhance mitochondrial function, leading to increased energy production, reduced inflammation, and accelerated tissue repair. When it comes to hair loss, the therapy is believed to boost circulation and blood flow to the scalp, bringing nutrients to stimulate new growth. It may also prolong the growth phase of the hair cycle and create a healthier scalp environment more conducive to hair growth.

  • Preliminary research on the efficacy of red light therapy for hair loss was published in 2020.

More research is needed to fully understand the long-term efficacy of red light therapy for hair loss. Experts recommend consulting a dermatologist to determine the underlying cause of hair loss and incorporating red light therapy into a comprehensive treatment plan.

The takeaway

While red light therapy shows promise as a potential treatment for hair loss, it is not a quick fix. Consistent use over several months is required to see results, and the therapy should be part of a broader approach to addressing the issue. As with any new treatment, it's important to consult a medical professional before trying it.
