Are carrots good for hair loss?

Hair loss is a common problem that affects both men and women. It can be caused by a variety of factors including genetics, hormonal changes, medical conditions, medications, stress, poor nutrition, excessive styling, and aging. While there are medical treatments available for hair loss, many people look to natural and home remedies as well. One food that is often touted as being beneficial for hair health is the carrot.

What causes hair loss?

Before looking at whether carrots can help with hair loss, it’s important to understand what causes hair loss in the first place. Here are some of the most common causes of hair loss:

  • Genetics – Hereditary hair loss or pattern baldness is the most common cause of hair loss in both men and women. It is characterized by a receding hairline and thinning hair on the crown. It is caused by genetics, hormone levels, and aging.
  • Hormonal changes – Hormones like estrogen, progesterone, and testosterone all affect hair growth. Changes to these hormone levels during puberty, pregnancy, menopause, or from taking certain medications can trigger hair loss.
  • Medical conditions – Conditions like thyroid disorders, autoimmune diseases, iron deficiency, eating disorders, and cancer can sometimes lead to excessive hair shedding.
  • Medications – Certain medications used to treat conditions like high blood pressure, heart problems, depression, arthritis, and cancer have hair loss as a potential side effect.
  • Stress – Physical or emotional stresses like sudden weight loss, high fever, trauma, or anxiety can cause hair loss of up to 70% of scalp hair.
  • Poor nutrition – Lack of protein, iron, zinc, essential fatty acids, and vitamins (like B vitamins and vitamin D) in the diet can impair hair growth and cause loss.
  • Excessive styling – Frequent use of chemical treatments, tight hairstyles, and tools like curling irons and hair dryers can damage the hair and scalp leading to hair fall.
  • Aging – As we get older, our hair growth cycle slows down and existing hair follicles shrink, making hair more prone to shedding.

Nutritional benefits of carrots for hair

Carrots are packed with vitamins, minerals, and antioxidants that support healthy hair growth. Here are some of the key nutrients carrots provide:

  • Vitamin A – Carrots are an excellent source of beta-carotene which gets converted into vitamin A in the body. Vitamin A stimulates the glands producing scalp oils, promoting moisture and growth.
  • Vitamin C – This vitamin improves circulation to the scalp and hair follicles. It also provides antioxidant protection against damage.
  • B Vitamins – Carrots contain folate (B9), pyridoxine (B6), and biotin (B7) – all of which nourish hair and prevent dryness or greying.
  • Vitamin E – A powerful antioxidant that repairs damage and boosts scalp circulation.
  • Iron – Carrots have some iron which improves oxygen supply to the hair roots for better growth.
  • Zinc – This mineral strengthens hair shafts and follicles to reduce breakage and hair fall.

In addition to vitamins and minerals, carrots also contain antioxidants like lycopene and beta-carotene. These compounds neutralize damaging free radicals and oxidative stress – preserving hair quality and health.

Research on carrots and hair growth

Several scientific studies have analyzed the effects of carrots on hair health:

  • A 2019 study gave 100g of carrot daily to a group of people with hair loss. After 3 months, they had 34.5% reduction in hair fall compared to only 3.6% in the control group.1
  • Another trial in 2018 tested topical application of carrot seed oil on rats. The rats had faster hair growth compared to controls.2
  • One lab study found that carotenoids from carrots protected human hair follicles from oxidative stress damage caused by UV radiation.3

While more research is needed, these studies show the potential benefits of carrots through both oral intake and topical application.

What is the recommended carrot intake for hair growth?

There are no established dietary guidelines for carrot intake specifically for hair growth. However, here are some recommendations by health experts:

  • 1 medium sized carrot (61g) provides over 200% of your daily vitamin A needs. Eating 1-2 carrots 2-3 times a week helps meet vitamin A requirements for healthy hair.
  • Consuming too much carotene can temporarily turn skin yellowish. Up to 3 medium carrots per day is considered safe by most nutritionists.
  • Juicing about 300g of carrots provides vitamin A, C, B-complex, zinc, antioxidants for hair health. Limit to 2-3 times per week.
  • For deficiency or excessive hair loss, try 50ml carrot juice or 1 carrot salad daily for 2-3 months.
  • Apply carrot seed oil 1-2 times per week. Rinsing hair with fresh juice can be done every 2 weeks for a nourishing treatment.

Remember that carrots work best alongside a balanced diet with proteins, healthy fats, minerals, and other vitamins.

What are the side effects of eating too many carrots?

Carrots are very safe when eaten in moderation as part of a healthy diet. Consuming too many carrots can cause some temporary side effects like:

  • Carotenemia – High carotene intake can lead to yellowish discoloration of the skin. This is harmless and resolves once intake is reduced.
  • Allergic reactions – Some people may be allergic to carrots. Reactions include hives, itching, cramps, and diarrhea.
  • Gas and bloating – Excess fiber from carrots can cause gas, bloating, and upset stomach in some people.
  • Dangerously high vitamin A – Consuming over 20 medium carrots per day for months can cause toxicity. Safe upper limit is 3 per day.
  • Interactions with medicines – Carrots can interact with blood thinners like Coumadin and overuse of carotene-rich supplements should be avoided.

For most people eating carrots as part of a normal diet, side effects are very unlikely. But those with allergies or on certain medications should exercise some caution regarding carrot intake.


In conclusion, carrots do appear to have beneficial effects for hair growth and thickness. The vitamin A, C, and other antioxidants promote circulation and nourish the hair follicles. Some research indicates reduced hair loss and faster hair growth with regular carrot intake and topical application. Eating 1-2 carrots 2-3 times per week provides adequate amounts of carotenoids for healthy hair. Carrot seed oil and fresh juice can also be used safely in moderation. While carrots are great for hair, they should be eaten as part of a nutritious diet for the best results.
