Are Hair Loss Supplements Safe? Doctors Reveal the Risks to Your Liver and Overall Health

From hair salons to social media mom groups, hair growth treatments are the talk of the town. Many women are experiencing more hair loss lately, thanks to hormonal changes, stress, aging, and even weight loss from certain medications. The need for solutions is growing.

Among the most sought-after options are oral hair growth supplements, which combine vitamins, minerals, and herbs. The global hair loss treatment market is booming, projected to reach over $3 billion by 2030.

However, as interest rises, so do concerns about safety. Recently, a case study linked a popular supplement to liver damage, sparking warnings from the FDA about certain topical treatments. What was once a simple question of “Do they work?” has now shifted to “Are they safe?”

Supplements: Not Always Safe

Many people think supplements are safer than medications because they are “natural.” But doctors warn against this idea. According to Dr. Chesahna Kindred, dermatologist, “Natural doesn’t always equal safe.” In the U.S., supplements are regulated differently than drugs, lacking rigorous safety testing before reaching store shelves.

For instance, biotin is common in hair products but can interfere with important lab tests. Dr. Melissa Piliang, another hair specialist, stopped recommending it after realizing its potential risks. “If it’s affecting lab results, it could lead to dangerous situations.”

The Journal of the American Academy of Dermatology even highlighted concerns about various supplements:

• Biotin: Risks with lab tests
• Vitamin E: Increased bleeding risk in high doses
• Saw Palmetto: Potential developmental issues in male fetuses
• Vitamin A: Can cause hair loss when overused
• Selenium: Excessive amounts can lead to brittleness and hair loss

Recently, a case study published in the American Journal of Gastroenterology documented a woman who developed liver issues after taking Nutrafol, a popular hair supplement. Doctors noted that the product contains several ingredients that could be toxic to the liver.

Dr. Piliang reassures current users of Nutrafol that the cases are rare but emphasizes the importance of understanding what you’re taking. “Always discuss supplements and medications with your healthcare provider. There may be interactions you’re unaware of.”

Prescription Treatments: Proceed with Caution

Prescription hair loss treatments also come with risks. Although doctors typically have a good grasp of potential side effects, the rise of telehealth has made it easier to access these treatments without adequate screening. In early 2024, the FDA warned about side effects from compounded topical finasteride sold online. These can include anxiety, depression, and sexual dysfunction.

Dr. Karan Lal explains that proper screening is essential. “In office visits, we ask the right questions and monitor for side effects,” he said. But this level of care may not be happening in telehealth situations where patients are quickly prescribed medications without thorough evaluations.

Conclusion

Deciding to use supplements or medications for hair growth isn’t trivial. It’s vital to weigh the benefits against potential risks. Always consult healthcare providers before starting any new treatment, especially when it comes to medications with multiple ingredients. Your health is worth that extra check-in.
