Vitamin A for Hair Growth


Vitamin (retinol, retinoic acid) is a nutrient important to vision, growth, cell division, reproduction, and immunity. Vitamin A also has antioxidant properties, and is considered to be good for hair health. In this article, we look at the role in which Vitamin A plays in promoting hair growth and preventing hair loss.

Does Vitamin A Promote Hair Growth?


It should be stated that all human cells need Vitamin A for growth, so that would include skin cells, tissues, and of course hair cells. The hair is the fastest growing tissue in the human body, and Vitamin A plays a key role in the development of cell growth and productivity.

So, in short, yes, Vitamin A definitely plays its role in the promotion of healthy hair growth. The recommended daily allowance of Vitamin A is 900 mcg per day for men, and around 700 mcg per day for women. By sticking to these daily dosages, one can expect some hair growth benefits.


Can Vitamin A Cause Hair Loss?

Some studies have shown that too much Vitamin A can indeed contribute to the loss of hair, as can too much selenium, although more studies are needed in order to confirm the accuracy of these findings.

This should deter you from taking Vitamin A, because the small scale studies have shown that there would need to be an excessive amount (around ten times the recommended amount) in order for it to cause hair loss. In general, Vitamin A is widely regarded as a vitamin that benefits the hair, particularly when taken in conjunction with other key vitamins, minerals, and extracts.


Health Benefits of Vitamin A

As well as benefiting the hair, Vitamin A is also good for eye health, bone health, and skin cell growth. Vitamin A can help prevent certain types of cancer, and it also helps support a healthy immune system. Vitamin A can also combat ageing, as well as reduce the effects of acne.

Vitamin A can be commonly found in foods like cheese, eggs, oily fish, milk, yoghurt, cereals, sweet potato, spinach, carrots and squash.



Insufficient levels of Vitamin A can lead to:


  • Inflamed skin
  • Poo eyesight
  • Skin ageing
  • Acne
  • Delayed human cell growth
  • Hair loss
