Vitamin A and Hair Growth: All the Facts Explained

Vitamin A is one of the best vitamins for hair growth because it will allow the follicles to enable the production of sebum (natural hair oils). There being enough sebum will ensure the hair and scalp get nutrients and strands will not dry out and break.

Vitamin A may also promote the circulation of blood and generate a barrier protection against harm in the environment. It’s important to have the right balance of vitamin A, as too much bitmain A can be toxic and lead to hair loss.

Here, we’ll look at the benefits of vitamin A, where it can be found, healthy consumption, and the risk of toxicity. We’ll also explore how Hairy Hair may help if you’re tackling hair loss.

What are the benefits of vitamin A?

Vitamin A is an essential part of a balanced diet and is fat-soluble. It can be found in a range of foods, so you should get enough from your diet, but if you have a deficiency, you may need to take a supplement.

Vitamin A is needed for many functions in the body, including your eyesight, immune system, growth, development, skin and hair health. It helps to stimulate the flow of blood to the scalp so that your hair follicles can receive enough oxygen and nutrients for healthy growth.

In warmer climates, vitamin A is important to prevent damage caused by UV rays by creating a protective barrier against damage.

What are the dietary sources and recommended intake of vitamin A?

You can find vitamin A in many foods, from carrots, kale, spinach, and sweet potatoes to eggs, butter, liver, and cheese.

Supplements are available in a variety of forms, such as gels, liquids, tablets, and capsules. For men, 700 micrograms is the recommended daily intake, while 600 micrograms is recommended for women every day. Women who are pregnant or breastfeeding will need more than this to pass on the nutrients to their babies.

It doesn’t require a high level of vitamin A to result in hair loss, but you won’t become toxic until 8,000 RAE.

What can a vitamin A imbalance cause?

The proper balance of vitamin A can help lead to healthy hair. Deficiency in vitamin A can lead to dry and brittle hair that is easily breakable. Restrictive diets or inflammatory bowel disorders can cause a vitamin A deficiency.

This can not only affect your hair growth, but vitamin A deficiency can lead to issues with your vision, skin health, and immune system.

An excess in vitamin A can also lead to problems for your body and hair, however. This typically happens if you’re taking too many supplements or concentrated foods. When sebum production increases from excess vitamin A, hair can become thinner as it disrupts the hair growth cycle, leading to inflammation. 

It takes the proper amount of sebum to help in hair growth. A poisonous dose of vitamin A will result in a headache or liver injury. If you worry about your level of vitamin A, contact a healthcare professional and speak with them about taking a multivitamin supplement so you do not overconsume vitamin A.

How can I combat hair loss from vitamin A toxicity?

If you’ve lost hair from vitamin A toxicity, there are some things you can do to try to regain it. If you can rebalance your vitamin A levels by eliminating any supplements from your diet and still observe your hair falling out, there could be something underlying causing your hair loss.

Because your body metabolises the excess vitamin A in your body, whatever toxicity symptoms you might develop should subside with time. To maintain healthy hair growth without taking supplements, make sure you’re getting enough vitamin A from your diet through foods that naturally contain vitamin A.

How can Hairy Hair help with my hair loss?

If you’re dealing with hair loss and want to try a comprehensive and convenient treatment option, Hairy Hair offers a daily pill that may be able to promote hair growth. 

The powerful combination of ingredients works to widen the blood vessels in the scalp so your follicles receive enough oxygen and nutrients while preventing testosterone from converting into dihydrotestosterone (DHT).

This hormone causes a process called miniaturisation, where your hair follicles shrink and eventually stop producing strands. 

Besides that, the supplement does contain antrual growth stimulators, and these can be capable of fuelling keratin production, which is the central protein in hair, and also inhibiting inflammation.

Conclusion

Vitamin A is important for healthy sebum production, so your follicles get the oxygen and nutrients required for healthy hair growth. Having a healthy amount of vitamin A is important so your scalp microbiome stays healthy.

Too much vitamin A causes hair loss, so if your levels are too high, you must stop taking any supplements that you may be taking and see a doctor.
