Hair loss can be a major cause of anxiety and insecurity for both men and women. While there are a number of treatments available, pills – when used correctly – can be a powerful tool to prevent hair loss.

But with a myriad of options out there, it can be hard to know which pills are the best fit for you. Here, we break down several options and explain how they work.

Finasteride (Propecia)

Also known by its generic name, Finasteride, Propecia is an oral medication that is FDA-approved for the treatment of male pattern baldness. It works by decreasing the production of DHT, a hormone that is responsible for hair loss.

One study found that taking Propecia for six months stopped hair loss in 90% of men. Another study showed that 65% of men who took Propecia experienced an increase in hair growth.

However, Propecia isn’t recommended for women who are pregnant or may become pregnant, as it can cause birth defects.

Minoxidil (Rogaine)

Minoxidil, sold under the brand name Rogaine, is a topical treatment that is applied directly to the scalp. It works by widening blood vessels, which allows more oxygen, blood, and nutrients to reach hair follicles.

This stimulates hair growth and prevents further hair loss.

A 2015 meta-analysis of several studies found that Minoxidil increased hair count and improved hair growth in both men and women. It’s also considered safe and effective for pregnant and breastfeeding women.

Dutasteride (Avodart)

Like Propecia, Dutasteride – sold under the brand name Avodart – works by blocking the production of DHT. However, it’s more potent than Propecia and can affect more areas of the scalp.

As a result, it’s been shown to be more effective in treating hair loss than Propecia.

However, Avodart isn’t FDA-approved for hair loss treatment. It’s typically used to treat an enlarged prostate, and doctors may prescribe it off-label for hair loss. As with Propecia, Avodart can cause birth defects in pregnant women.

Viviscal

Viviscal is a dietary supplement that contains a blend of marine protein, biotin, zinc, and vitamin C. It works by nourishing hair follicles from the inside out, promoting healthier, stronger hair growth.

Several studies have shown that Viviscal can improve hair growth and reduce hair loss in both men and women. One study found that women who took Viviscal experienced a 50% increase in hair growth and a 32% decrease in hair loss.

However, it may take several months to see full results.

Biotin

Biotin is a water-soluble vitamin that’s essential for the health of our hair, skin, and nails. It works by promoting the production of keratin, a protein that’s found in hair and nails.

While some studies have shown that biotin can improve hair growth, others have found no noticeable difference.

Omega-3 Fatty Acids

Omega-3 fatty acids are healthy fats found in fish, nuts, and seeds. They have a variety of health benefits, including promoting healthy hair growth.

One study found that women who took an Omega-3 supplement had less hair loss and increased hair density after six months.

Iron

Iron is a mineral that’s essential for hair growth, as it helps to carry oxygen to the hair follicles. A lack of iron can prevent hair from getting the nutrients it needs, resulting in hair loss.

If you suspect that you’re iron deficient – perhaps due to heavy periods or a vegetarian diet – it’s worth talking to your doctor about checking your levels.

Zinc

Zinc is a mineral that’s important for the health of our skin, nails, and hair. It helps to produce proteins that make up our hair, and it’s also involved in the process of cell reproduction.

Some studies have shown that taking a zinc supplement can improve hair growth, although others have found no impact.

B Vitamins

The B vitamins – including Biotin, B6, and B12 – are essential for healthy hair growth. They help to produce red blood cells, which carry oxygen and nutrients to the scalp.

Some studies have suggested that taking a B Vitamin supplement can help to reduce hair loss, although more research is needed to confirm this.

Conclusion

Hair loss can be distressing, but there are a number of pills and supplements available that can help to prevent or slow down the process.

While it’s important to consult with a doctor before starting any new medication or supplement, there are plenty of options to explore – from Minoxidil and Propecia to Viviscal, biotin, and beyond. With patience and persistence, many people find that they’re able to improve the health and appearance of their hair.
