best Biotin for Hair Growth products

Biotin supplements have gained popularity in the beauty and health industry, particularly for those seeking to improve their hair growth. Also known as vitamin B7 or vitamin H, biotin plays a key role in the body’s keratin infrastructure, which directly affects the strength and growth of hair.

While biotin deficiencies are rare, supplementation can be beneficial for individuals with low biotin levels to support healthier, stronger hair. When considering biotin for hair growth, the market is saturated with countless hair growth products.

They come in various forms, including capsules, gummies, and liquids, and often boast additional vitamins and minerals to support overall wellness. I spent numerous hours researching and testing various biotin supplements to find those that are not only effective but also come from reputable sources, ensuring that decisions are based on dependable information.

1. Vital Hair Boost

Vital Hair Boost

Customer Satisfaction: 92%

I will start with the best option at the market, Vital Hair Boost. I can attest that these capsules have been simple to add to my daily regimen, and after a couple of months, my once-thinning hairline began to show signs of life. I still use them in this today.  Sporting a fuller beard and stronger nails seemed like a nice bonus, too.

The formula includes kelp and bamboo, which they say target the health of the hair shafts, something I was pretty skeptical about at first, but my recent selfies don’t lie. While I’ve integrated it smoothly into my mornings, patience is key—I didn’t see instant results, and improvements were gradual.

I do think you have to be committed to taking the capsules over the long haul to really judge its efficacy. On the other hand, I didn’t experience any negative reactions. I must point that out.

What I liked
  • Noticed fuller beard and hairline improvements
  • Capsules are easy to incorporate into my daily routine
  • No adverse effects after starting this supplement
What I didn't like
  • Takes consistent, long term use to notice regrowth
  • Experienced a significant price hike upon reorder
  • Potential side effects could be concerning for some

2. Viviscal Women’s Hair Growth

Viviscal Women's Hair Growth

Customer Satisfaction: 83%

I used Viviscal for a while, and I noticed fewer hair strands on my brush in just a matter of weeks. The supplements fit comfortably into my morning routine, and my hair feels notably thicker. Of course, it’s important to manage expectations – Viviscal supports existing hair growth, meaning you won’t suddenly sprout new follicles.  But it does breathe life into what you’ve got.

The proprietary blend of Aminomar Collagen Complex and essential vitamins has given my hair a boost, especially during times when diet alone just wasn’t cutting it. While I’ve had a positive experience with Viviscal, I do have to be upfront about a couple of things.

First, the price point is a bit steep, which might not be feasible for everyone’s budget. And second, the inclusion of mollusk extract as a key ingredient means it’s off-limits for those with shellfish allergies. That is why I don’t use it today, but I must say that it was quite a good experience.

What I liked
  • Fewer breaks and less shedding
  • Noticeable growth within a few weeks
  • Suitable for all hair types
What I didn't like
  • Contains shellfish, an allergen for some
  • A bit pricey compared to other supplements
  • Results may vary for everyone

3. Primal Harvest Primal Hair Growth

Primal Harvest Primal Hair Growth

Customer Satisfaction: 77%

It seems that Primal Hair Vitamins might just become a non-negotiable part of your morning routine. The daily ritual is manageable – just two capsules with breakfast and that sets the tone for hair care from within. It is quite convenient option, don’t you agree? However, every rose has its thorns.

The price initially made me hesitate, but I took the plunge, hoping the investment would pay off in lush locks. For those on a tight budget, this could be a considerable setback. I’ve chatted with others who have tried these vitamins, and while there’s a buzz of excitement around the natural biotin kick, not everyone notices a drastic change.

Fortunately, I fall into the camp that has seen positive results. Always remember, results can vary from person to person.

What I liked
  • Noticeable hair growth and less shedding after consistent use
  • Supports overall hair, skin, and nail health
  • Capsules are easy to incorporate into a daily routine
What I didn't like
  • Prices are on the steeper side
  • Some may experience no significant change in hair growth
  • Potential for stomach discomfort in sensitive individuals

4. Mild by Nature’s Conditioner

Mild by Nature's Conditioner

Customer Satisfaction: 69%

I was initially curious about how well Mild by Nature’s Conditioner would work given that I have thin and somewhat lackluster hair. To my satisfaction, with consistent use, a difference in texture and volume became apparent. The jojoba and borago oil seem to contribute to a more luscious and hydrated feel, which is essential for anyone trying to revitalize their hair.

I moved on to another one, but it was a good options for a while. What I also appreciate is the eco-conscious approach. Knowing that what I’m using is vegan, cruelty-free, and devoid of GMOs and parabens gives me peace of mind that I’m not only taking care of my hair but also being environmentally responsible.

While some may find limited reviews to base their decisions upon, my firsthand experience has convinced me of this product’s merits.

What I liked
  • Significantly enhances hair thickness
  • Made with natural elements, promoting clean beauty
  • Free from harsh chemicals that could damage hair
What I didn't like
  • Limited reviews available for deeper vetting of performance
  • May not suit all hair types equally well
  • Specific effects can vary from person to person

5. Luseta Biotin Serum

Luseta Biotin Serum

Customer Satisfaction: 85%

My mom uses Luseta Biotion Serum, and I was fortunate enough to test it out myself. Given the harsh environmental factors and styling products I use, Luseta Biotin Serum was a heroic find. Using the serum has improved my mom’s hair health, reduced frizz, and helped me achieve that smooth, salon-finish look at home.

Like my mom, I also have color-treated hair, and this product has been an ally against fading and damage. Investing in this serum means you’re taking a measure to ensure your chosen hair color lasts longer while keeping your hair in optimal condition. You might need a little patience as well, as results are progressive and not overnight.

Lastly, for those on a tight budget, the price may seem a bit steep, but I find the quality justifies the cost.

What I liked
  • Significantly enhances hair thickness and shine
  • Designed with a lightweight formula that doesn’t weigh hair down
  • Offers color protection, which is great for treated hair
What I didn't like
  • The fragrance may not appeal to everyone
  • May not yield immediate results for all hair types
  • Higher price point compared to some competitors

6. Rainbow Research Henna and Biotin Herbal Shampoo

Rainbow Research Henna and Biotin Herbal Shampoo

Customer Satisfaction: 88%

What caught my attention was Rainbow Research Henna and Biotin Herbal Shampoo’s compatibility with color-treated hair — it maintained my color without causing any fading. Furthermore, the organic extracts, like marigold and chamomile, provided a gentle touch to my scalp.

However, it’s worth mentioning that this shampoo may not be ideal for all hair types. Although it’s oil-free and aims to condition, some might find it slightly drying. Those with particularly dry hair might need to follow up with a good conditioner.

The natural henna and organic scent might be off-putting for some who are used to more fragrant shampoos. But worry not, because the subtleness of the scent ensures it’s not overpowering and doesn’t linger too long.

What I liked
  • Enhances shine while strengthening with biotin
  • Complements color-treated hair without altering the color
  • Eco-friendly formulation that’s cruelty-free and pH balanced
What I didn't like
  • Could be slightly drying for certain hair types
  • Natural scent may not appeal to everyone
  • The nourishing effect might not suffice for very dry or damaged hair

7. Doctor’s Best Biotin

Doctor's Best Biotin

Customer Satisfaction: 91%

My hair feels stronger at the root, and the added shine doesn’t go unnoticed, and I have Doctor’s Best Biotin to thank for that. My nails, usually prone to splitting, have acquired a sturdiness that makes breakage a rare occurrence. Additionally, the compact capsules make the inclusion of this supplement into my regimen seamless and hassle-free, an aspect I’m sure to appreciate on busier mornings.

I’ve had to contend with minor skin breakouts, a trade-off I grapple with for the hair and nail benefits. Moreover, it’s tough to pinpoint if these capsules are the lone heroes in my journey towards enhanced hair and nail health, considering my holistic approach to wellness.

What I liked
  • Noticeable improvement in hair thickness and resilience
  • Enhanced nail strength, reducing brittleness
  • Small capsules, easy to swallow without any disagreeable taste
What I didn't like
  • Initial results took a few weeks to become apparent
  • Experienced a minor increase in breakouts, possibly related to biotin

Buyer’s Guide

biotin for hair growth buying guide

When selecting a biotin supplement for hair growth, I consider several factors that can influence the efficacy and safety of the product.

Purity and Ingredients

I look for supplements that specify the amount of biotin they contain and check if they are free from fillers, additives, and artificial ingredients. It’s important to ensure that the primary ingredient is biotin and not a blend that diminishes its potency.

  • Biotin Content: The biotin amount should be explicitly listed on the product label, emphasizing high purity. This ensures that I am informed about the exact quantity of biotin in each serving, allowing for an accurate assessment of its strength and quality.
  • Additives: The supplement should be free from unnecessary fillers, dyes, or artificial ingredients. The absence of these additives is crucial as they can often cause unwanted side effects or diminish the overall quality of the supplement.


The potency of biotin supplements can vary, typically ranging from 2,500 micrograms (mcg) to 10,000 mcg. When deciding on the appropriate dosage, several factors are considered:

Starting Dose

It’s common to begin with a moderate dose of biotin. This approach is cautious and helps to assess how the body reacts to the supplement. A moderate dose is generally considered safe for most people and is a good starting point for those new to taking biotin.

Dosage Levels

Moderate dosage level is deemed suitable for beginners or those who are just starting to take biotin supplements. A moderate dose is typically lower in potency and is less likely to cause any adverse effects. It’s a conservative approach to supplementing biotin, especially for individuals who have no specific health conditions that require a higher dose. A higher dose of biotin may be necessary for individuals with increased needs.

This could be due to various factors like dietary deficiencies, specific health conditions, or the body’s increased demand for biotin. However, it’s crucial to seek approval from a healthcare provider before opting for a high dose. This is to ensure that the high dosage is safe and appropriate for the individual’s health status and to avoid potential interactions with other medications or health conditions.

When determining the right dose of biotin, personal dietary restrictions or health considerations play a significant role. For instance, someone with dietary limitations that lead to biotin deficiency might require a higher dose. Similarly, certain health conditions might influence the body’s need for biotin, necessitating adjustments in the dosage. Regardless of the dose, it’s important to monitor for any side effects or reactions.

While biotin is generally considered safe, high doses might cause adverse effects in some individuals. Regular consultation with a healthcare provider is advisable to ensure the chosen dosage is effective and safe. Determining the dosage should be done through your scalp and how it reacts to the products.

Certification and Compliance

best Biotin for Hair Growth Certification and Compliance

The primary focus is on compliance with standards set by authoritative bodies like the U.S. Food and Drug Administration (FDA). The FDA sets guidelines for the safety, efficacy, and security of various products, including dietary supplements.

Ensuring that a biotin supplement meets these standards involves verifying that it is manufactured, labeled, and marketed in accordance with FDA regulations. This includes ensuring accurate labeling of ingredients, adherence to recommended dosages, and compliance with manufacturing practices that safeguard against contamination and ensure product consistency.

Good Manufacturing Practices (GMP) Certification

GMP is a system for ensuring that products are consistently produced and controlled according to quality standards. It covers all aspects of production, from the starting materials, premises, and equipment to the training and personal hygiene of staff.

A GMP certification for a biotin supplement indicates that the manufacturer is committed to producing a high-quality product by following procedures that minimize risks involved in production. This includes ensuring the cleanliness and safety of the manufacturing facilities, proper training of personnel, and rigorous quality control of the product.

NSF Certification

NSF International is an independent organization that tests and certifies products to ensure they meet public health and safety standards. An NSF certification on a biotin supplement suggests that the product has been independently tested and verified for quality, purity, and potency.

This certification is particularly important as it provides an additional layer of assurance to consumers about the quality of the supplement they are purchasing.

Additional Quality Indicators

Beyond these certifications, it’s also important to look for other indicators of quality in biotin supplements. This can include the use of high-quality ingredients, transparency in ingredient sourcing, and the absence of unnecessary additives or harmful substances.

Some manufacturers also conduct third-party testing and provide detailed information about their testing protocols and results, offering further assurance of product quality.


The supplements come in various forms—tablets, oil, capsules, gummies, or liquids. I choose based on my preference and convenience for daily intake.

Form Convenience Level
Tablets Standard, easy to store, can be split for dosage adjustment, but may be hard to swallow for some.
Capsules Often easy to swallow, masks unpleasant tastes, suitable for sensitive palates.
Gummies Tasty, chewable option, appealing flavors, ideal for those who dislike pills, but may contain added sugars.
Liquids Fast absorption, ideal for quick nutrient uptake and those with swallowing difficulties, but less convenient for travel due to potential leakage and refrigeration needs.

The cost of a supplement can be influenced by various factors, including branding, marketing, packaging, and distribution channels, which may not directly relate to its quality or effectiveness.

Evaluating Price vs. Quality

It’s crucial to find a product that strikes a balance between affordability and quality. This involves assessing the product’s ingredients, manufacturing standards, certifications, and form, as previously discussed.

A higher-priced product might offer additional features or benefits, but it’s important to evaluate whether these justify the extra cost.

Budget-friendly Options

Just because a supplement is budget-friendly doesn’t mean it compromises on quality. Many affordable supplements meet or even exceed quality standards. It’s important to ensure that even lower-priced options adhere to regulatory standards, have necessary certifications, and are manufactured using quality processes.

The key is to find a product that offers the essential benefits without unnecessary extras that might inflate the cost.

Premium Products

Premium supplements often come with a higher price due to perceived or actual added benefits. This could include organic or non-GMO ingredients, enhanced formulations, or specialty certifications.

When considering premium options, assess whether these additional benefits are relevant to your health needs and if they provide a tangible improvement over more affordable options.

If you found the initial choices for Biotin for Hair Growth lacking, fear not – a variety of specialized products is available to address specific hair concerns. Take a look at the list below for more options:


Is biotin safe for liver?
My research indicates that biotin is generally considered safe for the liver. As a water-soluble vitamin, it’s difficult to overdose on biotin since excess amounts are excreted through urine. However, I advise consulting a healthcare provider before starting any new supplement.
Is biotin safe for kidneys?
Biotin is safe for individuals with healthy kidneys at standard doses. Kidneys help in filtering excess biotin out of the body. Still, if there’s a pre-existing kidney condition, I suggest speaking with a healthcare professional to tailor the appropriate dosage.
Is 10 mg of biotin daily too much?
The recommended daily allowance (RDA) for biotin is much lower than 10 mg for most adults, and typical supplements contain 2.5 to 10 mg per serving. Although 10 mg is not generally considered to be harmful, it’s always best to adhere to the RDA or a doctor’s recommendation to avoid unnecessary intake.
Is it OK to take biotin at night?
Yes, you can take biotin at night. Since biotin doesn’t stimulate the body like caffeine, it typically doesn’t interrupt sleep patterns. However, individual responses may vary, so monitor how it affects you personally.
Why does biotin affect sleep?
Biotin itself is unlikely to affect sleep. If you’ve experienced sleep disturbances while taking biotin, it may be due to other ingredients in the supplement or a personal sensitivity. As always, it’s wise to review any sleep concerns with your physician to rule out underlying issues.

The Bottom Line

I’ve found that optimizing biotin intake can have a positive impact on hair growth. When selecting a biotin supplement, it’s crucial to consider factors such as dosage, ingredient quality, and the presence of additional nutrients that support hair health.

Finally, I encourage discussing with a healthcare provider before beginning any new supplement regimen. Every individual is unique, and a professional can offer personalized advice. Remember, consistent use and patience are key as results may take several months to become noticeable.
