Why Do You Need Vitamin A For Hair Growth

Amy Chang’s long, black hair has always fallen beyond her shoulder since third grade, and her hair became an afterthought due to keeping it consistent. She was oblivious to it. She’d dye it a darker shade of black every other month. She’d blow it out almost every day and use any hair treatments she could find. Chang would even forgo conditioner on occasion. 

One of the most essential and divisive vitamins for hair health is vitamin A. The reason for the debate over vitamin A is that, although little quantities may promote hair development, high levels can produce scalp oil problems, leading to hair loss. It implies that moderation is key when it comes to vitamin A: you’ll want to obtain enough to get all of the hair-growth advantages without going overboard and risking thinning. Vitamin A is advised at 900 micrograms per day for males and 700 micrograms for women.

If you keep to this dosage, you may anticipate all the advantages without scalp oil issues or hair thinning. Vitamin A is required for healthy immunological function, eyesight, and cell development. It’s also important for the health and operation of your internal organs, such as your heart, lungs, and kidneys.

Vitamin A is necessary for developing your hair, skin, and nails because of its function in cellular growth. Because vitamin A insufficiency is rare in industrialized nations, supplementing with the vitamin is typically unnecessary if you haven’t seen any deficiency symptoms.

If you opt to supplement your vitamin A, be careful not to overdo it. Consume no more than the quantity of vitamin A in most multivitamin pills since too much might cause shedding.

Why Can Too Much ‘Vitamin A’ Cause Hair Loss?

Vitamin A is a vital component for the human body, with several ramifications. Vitamins for hair loss are necessary for the body’s immune systems to work correctly and have normal eyesight. Vitamin A also helps keep healthy skin, teeth, hair, bones, and organs, including the lungs, liver, and kidneys.

Vitamin A is a potent antioxidant with various beneficial characteristics for your health. On the other hand, the World Health Organization cites “alopecia” as a symptom of chronic Vitamin A poisoning. It may happen if you take too many supplements containing this mineral.

It is not to argue that Vitamin A is a poison in and of itself, but it may act like one if consumed in large quantities. Hypervitaminosis A is the medical term for this condition.

Vitamin A is a fat-soluble vitamin, which may accumulate in the body and be stored in the liver. Sickness, dry skin, impaired eyesight, and irritability are all frequent side effects of too much Vitamin A. If you continue to overdose, you risk developing osteoporosis, internal organ damage, and, if you’re pregnant, birth abnormalities (Almohana).

How to proceed if Vitamin A is suspected of causing hair loss

If you suspect you have lost some hair due to taking too much Vitamin A, you should stop taking it or substantially limit your consumption. Because vitamin A is stored in the liver, your body will need to use up all of the reserves before you can take any more. If you’ve been taking a supplement, it’s possible that getting your Vitamin A from meals would suffice until your body’s reserves are depleted, and normalcy is restored. Your hair should regrow normally after your nutrition levels have been balanced.

If your hair loss is caused by anything else, too much Vitamin A might exacerbate the condition. In this instance, you should consult with your doctor to determine the reason for your hair loss and the best course of treatment.

Eggs, liver, fortified milk, and cereals are other good sources. You’ll obtain all the Vitamin A you need if you eat a healthy, balanced diet, and your body will be able to handle it normally rather than accumulating excess quantities, which might cause major health problems.
