What is Biotin?

Biotin, also known as vitamin B7, is a water-soluble vitamin that plays an essential role in the body’s metabolism. More specifically, it helps convert food into energy and aids in the synthesis of fatty acids, amino acids, and glucose. 

The vitamin is naturally present in a variety of foods, including eggs, nuts, seeds, avocados, and dairy products. It's also commonly added to hair and skin supplements due to its reputation for supporting the health and growth of hair, skin, and nails. 

But why is biotin good for African American hair growth, exactly?

Is Biotin Good for African American Hair Growth?

There’s a reason you hear so much about using biotin for black hair growth. This vitamin offers a few different benefits to support healthier, more beautiful hair. We’ll cover all these below along with a few side effects you should be aware of.

Benefits of Biotin for Black Hair Growth

So, why is biotin good for black hair growth? There are four main reasons you should consider adding it to your natural black hair care routine:

  • Strengthening Hair: Biotin helps produce keratin, a protein that makes up a large portion of hair. In this sense, biotin strengthens the hair by improving keratin infrastructure. This reduces breakage, a common issue in black hair types that often suffers from dryness and brittleness.
  • Encouraging Hair Growth: Regular biotin intake helps renew the follicles and roots of the hair with essential nutrients, promoting thicker and healthier new hair growth. 
  • Enhancing Hair Texture: Biotin supplements can improve the overall black hair texture, making it softer and more manageable. This makes it easier to manage and style as a result.
  • Moisturizing Benefits: While biotin itself does not moisturize hair, healthier hair follicles and strands can better retain moisture. It makes any deep conditioner for black hair you use more powerful.

That being said, biotin for black hair growth is not an African American hair growth secret - it’s well documented as an excellent way to regrow edges of African American hair or how to regrow bald patches in African American hair. But what’s the catch, if any?

Are There Any Side Effects or Drawbacks?

While biotin is generally safe and well-tolerated, high doses of biotin supplements can lead to skin breakouts or rashes. Too much of a good thing can be bad for you, after all.

It’s also been found to interfere with certain lab tests, especially those that measure hormone levels or cardiac markers. So, you’ll need to discuss this with your healthcare provider if you are undergoing lab tests.

As with any supplement, there is a potential risk of allergic reaction. Symptoms might include nausea, swelling, and dermatitis. 

So, what’s the verdict - is biotin good for black hair growth, or does the downside outweigh the benefits? Our opinion is that this is a safe, effective way to stop hair breakage in African American hair and encourage new regrowth. 

Plus, any adverse effects can be avoided with our serum here at Rennora Beauty! That being said, let’s talk about how to pick the best biotin for black hair growth below.

How to Pick the Best Biotin for Black Hair Growth

It’s clear that biotin can support healthier hair, but this is all contingent on getting a quality product. Not all forms of biotin are as bioavailable as others, and some can actually cause more problems than they solve. So - here’s how you can pick the best biotin for African American hair growth.

Different Types of Biotin Hair Products

Part of why biotin is such a popular addition to any hair growth routine is all the different forms you’ll find it in, from topical treatments to oral supplements. Here’s the pros and cons of each:

  • Topical Solutions: Serums and oils are often considered the most effective for hair care because they allow direct application to the hair and scalp. This enhances biotin absorption where it's needed most, potentially speeding up the results. Topicals not only deliver biotin but also often include other beneficial ingredients that moisturize and strengthen hair.
  • Oral Supplements: Pills or gummies are widely used and can support hair health from the inside out. While they benefit the entire body, their effects on hair might take longer to observe compared to topical applications. Still, they’re the most convenient way to harness the benefits of biotin for African American hair growth.
  • Shampoos and Conditioners: These are infused with biotin to combine cleansing and conditioning with hair growth benefits. While convenient, the contact time with the scalp and hair is shorter, which may reduce their effectiveness compared to other forms.

While each has its place, we believe that topical treatments are best, as you can perform a hot oil treatment for African American hair alongside other oils - like olive oil for black hair, castor oil for black hair, rosemary oil for black hair, and any other options we’ve discussed in our guide to the best oil for African American hair.

Assessing Potency and Purity

No matter which type of biotin product you choose you should ensure it’s as potent and pure as possible. 

So many hair care products are weighed down by additives and filler ingredients that don’t offer any additional benefits - instead, they can hold you back from reaching your hair health goals.

Look for products that clearly state the amount of biotin they contain. A higher dose isn't always better - instead, look for a balance that meets daily nutritional needs without exceeding them.

Certifications from third-party organizations can offer assurance of a product’s quality and purity so you can place your order with peace of mind. Look for seals from bodies like USP or NSF International.

User Testimonials

Many users may share before and after photos that visually demonstrate a product's impact on hair growth and health, almost like a crystal ball into your own future. 

But be careful about looking at reviews in isolation - what did or did not work for one person may not align with your own experiences. Instead, try and pull common trends from reviews after reading through many individual testimonials.


More expensive products can sometimes offer better quality or additional ingredients that justify the extra cost. However, this is not always the case. It’s important to take price with a grain of salt, and instead, focus on value.

Reasonable pricing combined with proven effectiveness often represents the best value for the money, which is really what matters most. After all, you’re trying to make your dream hair a reality - what price tag could you possibly place on that?

If you’re stressing about cost, some companies offer subscriptions, which can help you save money on every order while ensuring you always have your biotin available to avoid lapses in treatment.

Getting Started With Biotin for African American Hair Growth

Actually using biotin for black hair growth will vary based on the product you choose. If you end up going with an oral supplement, simply follow the manufacturer's guidelines for dosage and timing. 

But if you choose to set yourself up for success with the best biotin for black hair growth at Rennora Beauty, here’s how to make the most of our serum:

  • Daily Application: Use our serum daily for best results, placing a small amount on your fingertips and gently massaging it into your scalp and hair. Focus on areas that need the most attention, such as thinning spots or particularly dry sections. 
  • Increase Absorption: Simply applying the topical and calling it good won’t get you the results you want. A 5-10 minute scalp massage helps hair growth. Or, you can take this a step further with dermarolling for hair growth. Either way, the goal is to increase circulation at the scalp so the nutrients of our serum are absorbed into the skin where they’re needed most.
  • Wrap Your Hair: Because we recommend applying the serum 30-60 minutes before bed, it’s best to wrap your hair in a bonnet to avoid rubbing the ingredients off onto your pillow. This will lock the moisture in, too.
  • Consistent Use: Continue to use the serum as part of your daily routine to see improvements in hair strength, thickness, and overall health. While some women see results in just a few weeks, you should give it at least 3 months before making any changes. It’s worth the wait!

It’s really that easy!
