How Are Biotin and Collagen Better For Hair Growth?

If you've been searching for supplements to improve hair growth, you've probably stumbled upon biotin and collagen. People have touted both for their incredible hair-growth-enhancing properties. But before you stock up on either supplement, it's essential to understand how they might work.

Here, we'll explore what they are, how they support hair health, and which is better for hair growth to help you decide which supplement to choose.

What Is Biotin?

Sources of Biotin

Biotin is a B-complex vitamin, also known as vitamin B7 or vitamin H. It's present in many foods, such as eggs, legumes, nuts, meat, and fatty fish. As a vitamin, biotin is primarily involved in the metabolism of fats, proteins, and carbohydrates — meaning it's integral to converting food into energy. For your hair, this energy is crucial.

Fortunately, biotin deficiency is fairly uncommon. As long as you take a healthy, balanced diet, you probably won't have to worry about not getting enough biotin.

The Role of Biotin In Hair Growth

Biotin supports keratin production, the protein that makes up most of your hair. As a result, biotin deficiency can result in weak, brittle hair that's prone to breakage and thinning. This is why healthcare experts link biotin deficiency to hair loss. 

While biotin may be vital for hair growth, there isn't strong evidence that it enhances hair growth in non-deficient individuals. However, according to a study published in the Skin Appendage Disord journal, individuals with biotin deficiency experienced improved hair health after taking biotin supplements. 

So, if you suspect you might have a biotin deficiency, addressing it with a biotin supplement could improve your hair health. 

What Is Collagen?

Sources of Collagen

Collagen is the most abundant protein in the body, accounting for nearly 30% of total protein. Some great foods that can stimulate collagen production include chicken, fish, bone broth, eggs, berries, and citrus fruits. While collage is present all over the body, it's especially abundant in the skin, bones, muscles, nails, and hair.

The Role of Collagen In Hair Growth

As you age, your body's natural collagen production declines, which can lead to thinning hair and slower growth rates. Collagen-rich foods or supplements can help combat these effects.

According to a randomized, placebo-controlled study of women aged 35 or older, participants who took collagen supplements for three months experienced significant improvements in hair hydration, elasticity, coarseness, and density

So, if you suspect you might have a collagen deficiency, addressing it with a collagen supplement could improve your hair's thickness and stimulate hair growth.

Biotin Vs. Collagen: Which Supplement Is Better for Hair Growth?

Both biotin and collagen boast their own unique benefits, so the right supplement for you will primarily depend on your circumstances.

If you suspect you might have a biotin deficiency due to dietary restrictions, certain medications, or health conditions, taking biotin supplements can significantly improve your hair health and potentially reverse hair loss.

On the other hand, if you're experiencing age-related hair thinning, collagen supplements might be a good option. Collagen supplements support the scalp's structural integrity and improve hair follicle health, combating the effects of aging on hair.

So, when it comes to biotin and collagen, there's no one-size-fits-all option. That's why experts recommend taking a supplement with a combination of the two for best results.

Incorporating Biotin and Collagen Supplements Into Your Hair Care Routine

Liquid supplements offer a convenient way to add biotin and collagen to your diet. Unlike pills, liquid supplements are easy to swallow and absorbed faster, making them an effective way to address nutritional deficiencies.

You can incorporate a biotin and collagen supplement into your daily hair care routine by simply adding a few drops to your breakfast smoothie, water, or juice to reap the benefits of the nutrients. 

While you shouldn't expect immediate results, you might notice improvements in your hair's texture, strength, and health after some time. However, make sure you take the supplement daily as prescribed for optimal results.

Benefits of Biotin and Collagen Supplements Beyond Hair Growth

Besides supporting hair growth, here are some other benefits of biotin and collagen:


Benefits of biotin and collagen
  • Strengthen nails: There is evidence biotin can contribute to stronger and more resilient nails, reducing brittleness and breakage. However, the results are inconclusive, and more research is needed.
  • Blood sugar regulation: One study suggests biotin supplementation may help regulate blood sugar levels in people with type 2 diabetes. However, further studies are required.
  • Neuropathy management: One study suggests that biotin supplementation may reduce symptoms of peripheral neuropathy — a condition that's common in people with type 2 diabetes who develop nerve damage. However, researchers haven't yet conducted clinical trials on the efficacy of biotin supplements for this purpose. Thus, more research is needed.


    Benefits of biotin and collagen
  • Healthy skin: There is evidence that collagen may improve skin health by improving elasticity and hydration and even fighting against aging.
  • Joint health: Studies suggest collagen can help in rebuilding cartilage, offering relief from joint pain and stiffness, which is especially beneficial as you age.
  • Potential Side Effects of Biotin and Collagen Supplements

    Biotin and collagen supplements are generally safe when taken in recommended doses. However, here are some potential side effects of each:


    • High doses can interfere with some blood tests, especially thyroid function, reproductive hormone, and cardiac tests. Inform your doctor about your biotin intake if you're undergoing tests.
    • High doses of biotin can lead to digestive issues like nausea or diarrhea, though cases are rare.
    • High biotin doses may cause skin complications like rashes or swelling, though allergic reactions are uncommon.
    • Biotin supplements may interact with other medications, like antiseizure medications, which can affect how the body absorbs biotin. Consult your physician about possible interactions if you're taking medication.


    • Collagen may cause heartburn or bloating in some individuals.
    • Collagen derived from marine sources can cause allergic reactions among people who are allergic to seafood.

    While these side effects are rare, don't take chances. Before starting a biotin and collagen supplement regimen, consult your doctor, particularly if you have an underlying medical condition or are pregnant.

    Other Beneficial Vitamins and Minerals That Promote Hair Growth

    While biotin and collagen are two of the most popular supplements for hair growth, they aren't the only essentials. 

    Other critical vitamins and minerals include:

    Can Biotin and Collagen Supplements Improve Hair Health?

    Biotin and collagen supplements can support hair health by providing essential nutrients that promote hair strength and growth. While they may help with certain types of hair loss, ensure you consult your doctor to address the underlying cause of hair loss for targeted treatment.

    How Long Does It Take to See Results From Taking Biotin and Collagen Supplements?

    Results vary depending on individual health factors and consistency of use. However, many people start to notice improvements in their hair, skin, and nails within 8 to 12 weeks of regular supplementation.

    Can I Take Biotin and Collagen Supplements Together?

    Yes, you can take biotin and collagen supplements together, and experts recommend taking supplements that contain both for optimal hair growth and health. However, consult your doctor before you start taking biotin and collagen supplements.

    Can I Get Enough Biotin and Collagen Solely From My Diet?

    Yes, you might. Biotin-rich foods such as eggs, nuts, seeds, avocados, and some dairy products can provide biotin. On the other hand, bone broth, chicken skin, fish, and leafy greens can provide collagen. However, as you age, your diet may not supply enough collagen to counteract the decrease in collagen production. Incorporating collagen supplements into your diet can make up for collagen deficiency.

    Who Should Avoid Taking Biotin and Collagen Supplements?

    While biotin and collagen supplements are generally safe for most people, you should consult your doctor before starting a supplement regimen, especially if you have an underlying medical condition or are pregnant. 

    You might also want to exercise caution when taking collagen supplements derived from marine sources if you're allergic to seafood. 

    Finally, if you experience any side effects after taking biotin and collagen supplements, discontinue them and consult your healthcare provider.
