Frequently Asked Questions

What Vitamin Deficiencies Cause Hair Loss or Breakage?

Various studies link low levels of B vitamins (especially B12), iron, vitamin D, vitamin E, omega-3 fatty acids, and zinc to brittle hair and hair loss.

But before you jump into taking any hair supplements, you can have your doctor arrange a blood test to confirm a nutrient deficiency. Once you know what’s up, it’s easier to tweak your diet or add supplements to address your hair problems.

Do Hair Supplements Work?

Food supplements have a disclaimer for a reason—they’re not meant to cure, treat, or prevent diseases. Since they’re not FDA-approved, they’re not a bulletproof solution for your hair problems.

They might work great for some, not so much for others, or show varying results in terms of effectiveness.

If you’re not nutrient deficient, hair supplements probably won’t do much to improve your hair.

How Do Hair Supplements Work?

Hair vitamins and supplements work deep down at the cellular level, creating a more favorable environment for your hair to grow.

Which Is the Best Hair Vitamin for Faster Hair Growth?

Biotin is one of the best vitamins to grow your hair faster. It metabolizes proteins, fats, and carbs, which are essential for hair growth.

Biotin deficiency is rare but a biotin supplement ensures your body has what it needs to produce strong, resilient strands.

Vitamin D3 is another vitamin powerhouse that helps hair growth and supports overall hair health.

What Should I Look for in a Hair Supplement?

Start by checking out supplements that have scientific studies supporting their effectiveness, preferably from independent sources. Doing your homework upfront can really pay off.

Plus, get advice from a board-certified dermatologist to improve your odds of finding a hair supplement that works.

How Long Do Hair Supplements Take to Work?

Results may vary from person to person but on average, it takes about three months of consistent use to see noticeable improvements. That’s because your hair goes through a full growth cycle in roughly three months.

Some people might need to keep at it for a bit longer to see the full benefits. Just ensure to follow bottle instructions and maintain a balanced diet, healthy lifestyle, and good hair care habits.

Are Hair Supplements Safe?

Hair supplements are generally safe when used as directed and if you’re in good health. However, they do come with some risks. How safe they are depends on your overall health and the specific supplement you’re considering.

If you have an existing medical condition, some supplements may interact with your medications or affect the result of some lab tests. For instance, the American Thyroid Association says that high doses of biotin can give false laboratory results and mislead diagnosis.

So, it’s best to talk with your doctor before adding hair pills to your diet. Also, make sure your doctor knows if you’re taking any hair supplements if you’re trying to get pregnant.

What Are the Possible Side Effects of Hair Supplements?

The biggest issue with hair supplements is that they’re regulated by the FDA as food, not drugs, which means there’s not a ton of research on their possible side effects.

That’s why the Food and Nutrition Board has set limits on how much vitamins and minerals you should take to avoid toxicity.

Wrapping Up

So, there you have it—the best hair supplements for nourishing your locks from within.

If you suffer from nutrient deficiency, these hair growth vitamins can supply the nourishment your hair needs.

Remember that results may take time, so don’t lose hope if you don’t see immediate changes. Give it at least three months—a complete growth cycle for your hair—before deciding if it’s working for you.

Check with your healthcare provider and get some blood work to see if your nutrient levels are where they should be. And make sure to inform your doctor of any medications you’re taking.

What you put inside your body matters as much as your hair care routine. And always take care of yourself to get the healthy hair you’re after.
