Low-Intensity Laser Gains Ground as an Effective Treatment for Alopecia

A new generation of low-level laser (LLLT) devices is showing promising results in patients with moderate hair loss and androgenetic alopecia.

These devices, approved by health agencies in the U.S. and Europe, use specific wavelengths that stimulate blood circulation in the scalp and reactivate dormant hair follicles, without pain or significant side effects.

“The most recent studies show an improvement of up to 40% in hair density in patients treated consistently for six months,” says Dr. Laura Mendoza, a dermatologist specializing in trichology.

The highlight of this technology is that it allows patients to treat themselves at home, using portable, automated laser helmets or headbands, significantly reducing costs compared to more invasive clinical therapies.

Main advantages of hair laser treatment:

• Safe, painless and FDA approved.

• Compatible with other treatments such as minoxidil or finasteride.

• Ideal for early or mid-stage hair loss.

• Home treatment, without the need for direct medical intervention.

Although it does not yet replace hair transplants in advanced cases, it is positioned as a first-line alternative for those seeking a non-surgical solution.
