Vitamin A For Scalp


The human body needs Vitamin A to maintain healthy cells and tissues. It also helps your eyes function properly, boosts your immune system, and keeps you from getting sick. But there’s one place that Vitamin A can be especially beneficial: your scalp.

When applied topically to the skin, Vitamin A can help treat dryness, itchiness, dandruff and other conditions that affect the scalp. Read on to learn more about how vitamin A can help you keep your hair healthy!

The Role Of Vitamin A In Skin And Scalp Care. Photo by Pixel-Shot

Vitamin A is an essential nutrient for the body, playing multiple roles in skin and scalp care. There are two types of vitamin A – retinoids (preformed) and carotenoids (proformed). Both types are converted by the liver to a derivative called retinol. If it isn’t used immediately, it’s stored by the body or transported via the lymphatic system to the cells where it stimulates, strengthens, heals, balances and more. Today we’re covering the various ways in which vitamin A (retinoids and retinol) aid the skin and scalp, concluding with our top tips for introducing vitamin A into your routine.


  • Balances and heals. When the sebaceous glands go into over-production, we experience clogged pores, breakouts, adult acne and oily skin/scalp. Vitamin A helps to reduce the amount of sebum (the body’s natural oil) which causes these by promoting cell turnover, exfoliating and removing dead skin cells from the epidermis. As a result, the skin and scalp are re-balanced, inflammation is reduced, hair growth is stimulated and scarring begins to heal.
  • If the sebaceous glands are underactive and sebum is naturally lacking in the body, vitamin A helps to produce this, ultimately moisturising the skin and scalp, preventing them from becoming overly dry, making hair glossy and skin radiant.
  • Evens skin tone. Melanocytes create the pigment called melanin. This pigment provides some protection against the sun and gives colour to our skin and hair. When we are over-exposed to UVA and UVB rays, the production of melanocytes increases, resulting in hyperpigmentation or skin spots. As a powerful antioxidant and fat-soluble vitamin, Vitamin A helps to repair this damage and distribute melanin effectively (reducing discolouration) by increasing blood flow and inhibiting the activity of tyrosinase – an oxidizing enzyme responsible for the melanin-forming process.2
  • Promotes structural protein production. Vitamin A can slow down the normal ageing breakdown of collagen, elastin, and keratin which all act as building blocks for supple skin and healthy hair growth. Retinoids increase their production by stimulating fibroblasts to synthesise collagen, strengthening elastin and accelerating keratinization.


  • Some great sources for getting vitamin A from your diet are cheese, eggs, oily fish and liver. However, the body can also convert Beta-carotene into retinol from yellow, red and green (leafy) vegetables, such as spinach, carrots, sweet potatoes and red peppers, yellow fruit, such as mango, papaya and apricots.
  • Too much vitamin A (high concentrations of retinol/retinoids) can cause damage and sensitivity so SPF is a must if applying topically.
  • Too much vitamin A in the diet can also lead to brittle hair and cause hair loss (follicular hyperkeratosis – too much keratin in the hair follicles) so always start with low concentrations, increasing if needed.
  • Apply at night when the skin and scalp are free to breathe, ready to absorb, and are in regeneration-mode.
  • Our Scalp OilFace Oil and Eye Oil all contain naturally vitamin A rich oils such as Rosehip OilMoringa Seed Oil and Baobab Seed Oil.
  • Always do a patch test when using a new product as some sensitive skins (like our Founder’s) cannot take retinols / retinoids.

Are vitamins for hair growth right for you?

Vitamins are not the end-all-be-all for all hair problems. They’re not magic, and will not transform your hair overnight. However, some vitamins can help ease the thinning or brittleness of hair that comes with age or hormones. 

  • Before considering vitamins for your hair, ask yourself the following questions.
  • Am I missing any key nutrients in my diet?
  • Am I taking the recommended daily amount of vitamins A, B, C, D or E?
  • Am I consuming the daily amounts of iron, omega-3s or zinc? 
  • Could my hair benefit from a bit more care?

Keep in mind that hair loss can be due to an underlying medical condition. Always contact your doctor with your concerns before starting any type of vitamin supplement.
