So many of us have grown up hearing about the benefits of this fascinating B7 vitamin, but not many understand what it is and what it can do for our hair, skin, and nails.

In today’s blog, we’ll look into the benefits of vitamin B7, using biotin for hair growth, and the best biotin supplement for hair.

What is biotin?

To understand the benefits of vitamin B7, we have to take a deeper look into what exactly this powerful vitamin is.

Simply put, biotin (also known as vitamin H) is a water-soluble vitamin that’s a part of the wider B vitamin family. It’s one of the many complex vitamins that help our bodies convert the food we eat into nourishment and energy. In addition to aiding in energy conversion, biotin is also great for our hair, skin, and nails. That’s the reason why it’s so common to see biotin for hair growth advertised in a lot of products!

The word “biotin” is derived from the Greek word “biotos”, which translates to “life”. This makes sense because biotin plays a crucial role in the bodily processes that keep us alive. Naturally, it’s important to make sure you’re getting enough biotin, which is where the best biotin supplement for hair can come in. There are also a variety of foods with naturally occurring biotin, which we’ll dive into later!

Which kind of biotin is best for hair growth?

Depending on your hair needs, you choose for a biotin supplement for hair or a product that applies biotin topically. When it comes to biotin for hair growth specifically, there are a few things to consider before choosing a product. Below is a quick breakdown of the different ways you can take biotin for hair growth.

Biotin as an oral supplement:

Most people choose to enjoy the benefits of vitamin B7 as an oral supplement. Regardless of whether or not you’re suffering from a biotin deficiency, taking a daily supplement can help ensure you’re getting enough biotin. Available in tablet and gummy form, a biotin supplement for hair growth is the most common form of oral supplement you’ll find. Overall, oral supplements are great for growing longer hair because of their ability to absorb quickly into the bloodstream.

Biotin as a topical solution:

Biotin shampoos and other products that offer a topical solution can be helpful for brittle or unhealthy hair, but they aren’t as effective at reversing hair loss. However, many topical biotin treatments contain the benefits of vitamin B7 with other helpful proteins like keratin that may help to reduce split ends and breakage. So, if you’re looking to grow longer hair without breakage, you might want to try these types of products!

How do biotin supplements for hair work?

If you don’t think you’re getting enough biotin from your diet, or if you’re just looking to up your dosage, supplements may be an option. Biotin supplements for hair are an easy, practical way to enjoy the benefits of biotin for hair growth over time.

So how do biotin supplements for hair work? They work to enrich the hair with extra nourishment through easily absorbable biotin. This helps strengthen the hair follicle and shaft, making hair more resilient. With consistent use, biotin supplements for hair can improve hair texture, shine, and strength. Additionally, it’s common to take biotin for hair growth as well, and many people begin to experience results after a month of continuous use.

How to combine biotin supplements for hair with other hair-loving ingredients

If you want to use biotin for hair growth, we recommend taking it as a part of a multivitamin that combines the benefits of vitamin B7 with other hair strengthening ingredients such as:

  • Silica (from bamboo extract) - This naturally-derived ingredient contributes to the maintenance of normal hair as well as protection of cells from oxidative stress
  • Vitamin D - Helps to stimulate hair follicles to grow. Research shows that people with alopecia areata have much lower levels of vitamin D than people who do not have alopecia
  • Zinc - Zinc deficiency can cause hair loss as well as brittle hair, skin and nails
  • Selenium - Authors of a scientific review note that selenium is involved in creating hair
  • Vitamin C - Blocks damage from harmful free-radicals and boosts collagen production as well, which is beneficial to hair, skin, and nails

Biotin-rich foods to eat

If you’re increasing your biotin intake through food, you’ll need to eat several biotin-rich foods daily to ingest enough biotin to make a difference. It’s also worth mentioning that to experience the benefits of biotin for hair growth, a lot of these foods need to be eaten raw or only minimally processed. The following foods contain a variety of benefits of vitamin B7:

  • Salmon
  • Eggs
  • Sweet potatoes
  • Almonds
  • Oatmeal
  • Bananas

When eating biotin for hair growth, remember that it’s a water-soluble vitamin. This means that if you want to get a high enough intake through food, you’ll have to eat a lot of these foods every single day. This is why many people choose to take a biotin supplement for hair in addition to eating these biotin-rich foods.

How long until you see hair growth results?

When it comes to biotin for hair growth, most people won’t see any noticeable benefits until they’ve increased their intake for several months. For best results, you should be consistent in your intake, and be patient! According to this double-blind study, participants taking a biotin supplement for hair didn’t notice visible results until 90 days into the trial.

Once you start taking a biotin supplement for hair growth, make sure to take it every day. We recommend setting a reminder on your phone that goes off at the same time each day so you never miss a day!

Other benefits of vitamin b7

Did you know that the best biotin supplement for hair can carry a lot of benefits besides hair health? It’s true! There are other benefits of vitamin B7 you can experience other than just biotin for hair growth. Taking the best biotin supplement for hair can help improve your skin and nails as well!

Along with using other compounds like collagen, taking a biotin supplement for hair is believed by some to help with skin health, as those experiencing a biotin deficiency often report skin conditions like rashes. While the jury is still out, some have claimed that taking biotin improved their overall skin texture and helped control acne.

Additionally, if you’re struggling with dry or brittle nails, biotin has been proven to help. After taking biotin, 91% of participants in this study experienced healthier, stronger nails. As you can see, biotin for hair growth isn’t the only benefit!

Does biotin come with any side effects?

While there are plenty of benefits of vitamin B7, even the best biotin supplement for hair can potentially cause side effects for some.

According to the NIH, there is no evidence that biotin is toxic at high levels. However, some may experience an upset stomach or skin rashes while taking biotin supplements, though this side effect is rare. In the EU, there are no limits to how much B7 can be in a biotin supplement for hair because, in clinical trials, no serious side effects have been shown. Biotin is a water-soluble vitamin, and any amount that the body does not absorb is excreted naturally.

But as with all supplements, if you have any medical conditions, it may be beneficial to check with a doctor before trying biotin for hair growth.
