Hair Growth Treatments Explained: Dr. Daniel Gould Featured in GQ

Beverly Hills plastic surgeon Dr. Daniel Gould, MD, PhD was featured in GQ discussing the science behind hair growth products and how patients should approach treatments for thinning hair or hair loss.

Hair thinning and hair loss can occur for a variety of reasons, including genetics, hormonal changes, stress, nutritional deficiencies, and aging. Because the causes vary from person to person, experts emphasize that the effectiveness of hair growth products depends heavily on the active ingredients used and the underlying cause of hair loss.

“The efficacy of hair growth products depends on the active ingredients and the underlying cause of hair loss,” Dr. Gould explains. “Patients should be cautious of exaggerated marketing claims and consult with a qualified physician to determine the best evidence-based treatment plan.”

Evidence-Based Hair Growth Treatments

Several clinically studied treatments are commonly used to help improve hair density and slow hair loss progression.

These include:

• Minoxidil, which can extend the growth phase of hair follicles
• Finasteride, which reduces the hormone DHT that contributes to hair loss
• Low-level laser therapy (LLLT), which may stimulate hair follicle activity
• Nutritional supplementation, when deficiencies contribute to hair thinning

Each treatment works differently, which is why personalized evaluation is often recommended before starting a regimen.

How Minoxidil Supports Hair Growth

Minoxidil is one of the most widely used treatments for hair loss and is available in several topical formulations.

The medication functions as a vasodilator, which helps improve blood flow around hair follicles. By extending the anagen (growth) phase of the hair cycle, minoxidil may help improve hair density and thickness in certain patients.

However, results vary depending on factors such as genetics, hormone levels, and overall scalp health.

Emerging Technologies for Hair Regrowth

New technologies are also being explored for treating hair loss. One example is low-level laser therapy, commonly delivered through LED helmets or light devices designed to stimulate the scalp.

According to Dr. Gould, red-light therapy has shown promising results in some studies for improving hair thickness and stimulating follicular activity.

As research continues, physicians are increasingly combining medical treatments, devices, and lifestyle interventions to create comprehensive hair restoration plans.
