Does Low-Level Light Therapy Work?

In our modern-day, scientists and doctors have made great strides in developing methods to treat hair loss in men and women. One of these methods, low-level laser therapy (LLLT), has become increasingly popular. Doctors have confirmed that low-level laser therapy will stop hair loss in 85% of patients, among a variety of other benefits, and will stimulate hair growth.

History of Low-Level Laser Therapy

While low-level laser therapy (LLLT) technology might seem recent, it has actually been around since the 1960s, where the first laser was created at the Hughes Research Laboratory in California. A few years later, testing was done with LLLT and its effects on skin cancer. During experiments, positive effects of low-level lasers on hair growth, wound healing, and musculoskeletal conditions was seen. These discoveries earned laser medicine and the discoverer of low-level lasers’ positive biological effects.

Low-level lasers, also known as “soft” or “cold” lasers, was implemented into therapy options geared toward restoring hair loss. In 2007, the US Food and Drug Administration cleared the first home medical laser device to treat hair loss in men with androgenetic alopecia (pattern baldness). Four years later, in 2011, the FDA cleared a similar device to treat hair loss in females with androgenetic alopecia. Since then, technology has continued developing, and other devices have been approved by the FDA, such as the LaserCap.

How Does Low-Level Light Therapy (LLLT) Work?

The laser emits photons into the scalp to stimulate mitochondrial activity which increase energy for hair follicles. This increases synthesis of protein and increases cell proliferation. These conditions lead to increased growth factors in follicles that cause them to enter the anagen growth phase.

What are the Benefits of Low-Level Laser Therapy?

The main benefit of using low-level laser therapy is stopping hair loss progression, and increasing hair growth. Other benefits include:

  • 54% increase in blood flow to the scalp
  • 25% increase in hair volume
  • Improved skin cell health leading to alleviated scalp irritations such as dryness, peeling, or excessive oiliness.

Whether used as a standalone treatment or in combination with other treatments, low-level laser therapy has become an integral part of treating hair loss in men and women.
