What Vitamins & Supplements are Good for Hair Growth

Hair loss, thinning, and slow hair growth are common concerns for many individuals. And, your hair health can be impacted by a range of factors, including genetics, hormonal imbalances, stress, nutritional deficiencies and your environment. Even the harsh chemicals and treatments that we use to style our hair can have a detrimental impact on the health of your hair and scalp. It's no secret that having a healthy head of hair is desirable, but achieving it can be a challenge. While many factors can contribute to achieving those long luscious locks, getting the right vitamins and supplements can be an important first step, as they can play a crucial role in promoting scalp health. And, since healthy hair starts at the roots, incorporating the proper vitamins and supplements into your hair regimen can play an important role in helping you achieve your hair goals. 

But with so many vitamins out there, how do you know which ones are actually worth your time and money? If you’re wondering what the best vitamins are for a healthy scalp, we’re here to help! From biotin and vitamin D to other hair-health secret weapons, we'll cover the key vitamins and supplements that can help you achieve a healthier scalp and promote hair growth. So, whether you're dealing with hair loss, breakage, or just want to improve the overall appearance and health of your scalp and hair, keep reading to learn more about the best vitamins and supplements to give your hair the boost it needs.

So, What Vitamins Help Hair Growth?

Are you tired of constantly dealing with split ends and lackluster hair? Maybe you're frustrated with slow hair growth or noticing increased hair loss? Whatever the case may be, the journey to better hair may be as simple as adding some vitamins to your hair care routine. That's right, certain vitamins can work to promote scalp health, strengthening your locks from root to tip and helping to aid hair growth. 

Here, we'll be sharing some of the key vitamins for hair growth, along with their benefits. From biotin to vitamin D, we'll cover all the essential vitamins that can help you achieve the strong, healthy hair you've been dreaming of.


First up, let's talk about biotin. You've probably heard of this one before, and for good reason. This vitamin’s role in the hair growth process has led it to become a popular hair vitamin for those looking to achieve beautiful hair. Biotin, also known as vitamin B7, helps your body produce keratin, a protein that makes up the structure of your hair (and nails, too!). It also promotes scalp health by stimulating cell growth in the hair follicles.  

Biotin supplements can be taken to support healthy and beautiful hair. Plus, biotin shampoos and conditioners are also available, which help to nourish and protect hair from damage. Additionally, biotin-rich foods like eggs, nuts and leafy greens can be incorporated into a healthy diet to promote hair growth and overall health. So, if you're searching for vitamins that will help promote those long healthy locks, you should consider adding biotin to your healthy-hair regimen.


If you’ve been on the hunt for the best vitamins for hair growth for some time, you've probably come across biotin. But, have you met the hair-loving hero, Lustriva®? This secret weapon combines Bonded Arginine Silicate with Magnesium Biotinate to create a "super biotin" that significantly increases biotin absorption. The result? An extra-strong boost for your locks that can promote noticeably healthier-looking hair. And, clinical studies have shown that Lustriva® can promote a significant increase in hair thickness. Overall, Lustriva® is an incredible ingredient to add into your hair-health routine, and can give your hair that extra boost you’ve been wanting.

Vitamin E

Alright, it's time to talk about vitamin E—a true superhero amongst hair growth vitamins! But what does vitamin E do for your hair exactly? This antioxidant powerhouse does wonders for your locks by protecting it from damage and promoting healthy growth. Vitamin E works by reducing free radicals, which are harmful molecules that can cause damage to your hair and scalp. By protecting your hair and scalp from these molecules, vitamin E helps prevent breakage and split ends, which can aid in achieving healthier, longer hair. 

But that's not all—vitamin E also promotes blood circulation to the scalp, which is essential for healthy hair growth. And last but not least, vitamin E also has moisturizing properties, which can help prevent dry, brittle hair. This is especially important if you're someone who uses hot tools or chemical treatments for styling. By keeping your hair hydrated and healthy, vitamin E helps prevent damage that can lead to hair loss, leaving you with the healthy looking hair you’ve always dreamed of having. 

Vitamin C

Next on the list is vitamin C—the vitamin that's not just good for immune system support, but also for promoting healthy hair growth! This important vitamin helps protect your hair from damage and keeps your scalp healthy, which again, is essential for those luscious locks.

Vitamin C works its magic by helping your body produce collagen, which is a protein that's essential for healthy hair growth. Collagen is what gives your hair its structure and strength, so making sure you're getting enough vitamin C is key if you want to avoid hair breakage and damage. But vitamin C isn't just good for your hair - it's also great for your scalp! Vitamin C helps support healthy circulation in the scalp, which means that your hair follicles are getting more of the nutrients they need to grow healthy and strong. And, incorporating vitamin C into your routine can be done in a variety of ways, such as through supplements or a scalp serum, to help you achieve a healthy scalp and hair. 

KSM-66® Ashwagandha Root Extract

Known as "Winter Cherry" or "Indian Ginseng," ashwagandha is an adaptogen that boasts an array of benefits. From boosting your energy levels to reducing stress and supporting your immune system, this powerful plant extract has got you covered. If you’re looking to incorporate ashwagandha root extract into your hair care routine, look no further than KSM-66®. This high concentration ashwagandha extract has been perfected by experts for over 14 years, and is the most clinically studied ashwagandha on the market. Incorporating ashwagandha, such as KSM-66®, into your scalp-health routine may provide stress-reducing benefits that can potentially help reduce hair loss, making it an effective addition to your regimen.

Vitamin D 

Did you know that vitamin D is not only essential for strong bones but also for healthy hair? That's right, this sunshine vitamin plays an important role in the hair growth process. Vitamin D aids in the stimulation of hair follicles, thereby facilitating the active growth phase known as the anagen phase. It also contributes to the overall health of your scalp, which can promote healthy hair growth. Inadequate vitamin D levels can lead to inactive hair follicles, causing hair thinning and loss. Therefore, ensuring that you obtain sufficient vitamin D through sunlight exposure, diet, or supplementation can promote the growth of long and healthy hair.

Vitamin A 

Vitamin A is yet another essential nutrient that helps to promote healthy hair growth and prevent hair loss. One of the most important functions of vitamin A for hair is its role in producing sebum. Sebum is a natural oil that moisturizes the scalp and prevents hair from becoming dry and brittle. And, without enough sebum, hair can become weak and prone to breakage, leading to slow growth and increased hair loss.

But that's not all - vitamin A also helps to stimulate the production of new hair cells. This means that it can help to promote healthy hair growth and prevent hair loss by ensuring that hair follicles are constantly producing new strands of hair. However, it's important to note that too much vitamin A can actually be harmful to your hair. Excessive amounts of vitamin A can cause hair loss, so it's essential to get the right amount. The recommended daily intake of vitamin A is 700–3,000 mcg.

So, where can you find this hair-loving nutrient? Along with taking supplements that contain vitamin A, some good sources of this vitamin include sweet potatoes, carrots, spinach and kale. And, these delicious veggies are not only good for your hair, but they're also packed with other essential vitamins and minerals that promote overall health—a win-win!

Vitamin B-12

Vitamin B-12, also known as cobalamin, is a water-soluble vitamin that is essential for healthy hair growth. It plays a vital role in the formation of red blood cells, which carry oxygen and nutrients to the hair follicles. Without enough oxygen and nutrients, hair can become weak and prone to breakage, leading to slow growth and hair loss.

Vitamin B-12 also plays a role in the metabolism of amino acids, which serve as the fundamental building blocks of protein. And, as hair comprises the protein keratin, it is important to obtain adequate amounts of vitamin B-12 to enable the synthesis of keratin, necessary for maintaining strong, healthy hair.

It’s important to know that vitamin B-12 is not naturally produced by the body and must be obtained through diet or supplements. Some good sources of vitamin B-12 include meat, fish, eggs and dairy products. And, particularly if you're a vegan or vegetarian, you may need to supplement your diet with vitamin B-12 to ensure that you're getting enough.  

Maintaining a healthy scalp is essential for promoting hair growth, and incorporating the right vitamins and supplements into your hair care routine can help you achieve healthy, luscious locks from root to tip. Vital nutrients like biotin and vitamin D provide essential support to improve hair strength and appearance. Achieving long, healthy hair may be challenging, but with the right vitamins and supplements, you can transform the health of your hair and scalp. So, if you're looking for an extra boost to achieve your hair goals, try incorporating these vitamins into your routine and watch your hair thrive.
