6 Best Juices for Hair Growth

Orange juice, carrot juice, and tomato juice are three practical choices for supporting hair growth, although none has been proven to make hair grow faster.

The six juices below are selected for their potential nutritional contribution, not ranked by proven effects on hair growth. If you are concerned about hair loss, the ai symptom analyzer may help you organize your concerns, but it cannot diagnose the cause. For a broader look at beverages, see the best drinks for hair growth.

What are the 6 best juices for hair growth?

Hair follicles need a range of nutrients, and a varied diet helps supply them. Juice may contribute some vitamins, but it cannot correct every nutritional shortfall or address non-nutritional causes of hair loss. Eating whole fruit and vegetables is generally preferable because they retain more fiber.

Direct research on drinking these juices for hair growth is lacking. A small clinical trial of onion juice tested it on the scalp for patchy alopecia areata, not as a drink, so it does not establish that drinking onion juice promotes hair growth.

1. Orange juice

Why consider it: Orange juice supplies vitamin C, which helps the body absorb iron from plant foods. Iron is important for normal hair growth, particularly when an inadequate intake contributes to a deficiency. Orange juice is not itself a reliable source of iron, so pair it with an iron-containing food such as beans or lentils.

How to use it: Choose pasteurized, 100% orange juice rather than an orange-flavored drink with added sugar. Diluting it makes a larger, less sweet drink but does not remove sugar from the juice.

• 120 mL (1/2 cup) 100% orange juice
• 120 mL (1/2 cup) water

1. Pour the orange juice into a glass.
2. Add the water, stir, and serve.

Evidence: The nutritional role of vitamin C is established, but there is no direct evidence here that drinking orange juice increases hair growth. If you suspect iron deficiency, ask a clinician about testing rather than relying on juice to correct it.

2. Carrot juice

Why consider it: Carrot juice provides beta-carotene, which the body can convert to vitamin A. Vitamin A supports normal cell function, including in tissues involved in hair growth. More is not necessarily better: excessive preformed vitamin A from supplements can be harmful, and a carrot drink is not a substitute for assessing a deficiency.

How to use it: Choose 100% carrot juice and check the label if you prefer a product without added sugar. Its naturally sweet flavor works well diluted with water.

• 120 mL (1/2 cup) 100% carrot juice
• 120 mL (1/2 cup) water

1. Pour the carrot juice into a glass.
2. Add the water, stir, and serve.

Evidence: Beta-carotene’s role as a vitamin A source is established, but studies have not shown that drinking carrot juice makes hair grow faster. Nutrient content and absorption can vary with the product and preparation.

3. Tomato juice

Why consider it: Tomato juice can contribute vitamin C, which supports iron absorption and normal collagen production. Collagen is a structural protein, but that does not mean drinking tomato juice will directly strengthen or regrow hair. Tomato juice also supplies potassium, which matters when choosing foods for some kidney conditions.

How to use it: Look for pasteurized, 100% tomato juice; a lower-sodium option can help limit added salt. Serve it on its own if you prefer a stronger flavor.

• 120 mL (1/2 cup) 100% tomato juice
• 120 mL (1/2 cup) water

1. Pour the tomato juice into a glass.
2. Add the water, stir, and serve.

Evidence: Tomato juice can be part of a varied diet, but there is no direct evidence here that it improves hair growth. Its vitamin C content varies by product and processing.

4. Strawberry juice

Why consider it: Strawberries provide vitamin C, making strawberry juice another option to have with a plant-based meal containing iron. Some nutrients pass into the juice, although the amount depends on preparation, and straining removes fiber along with the pulp.

How to use it: For a simple homemade drink, blend washed strawberries with water and strain if you prefer a juice-like texture. Eating the strawberries whole retains more of their fiber.

• 75 g (1/2 cup) sliced strawberries
• 120 mL (1/2 cup) water

1. Wash the strawberries under running water and remove the tops.
2. Blend with the water, strain through a clean sieve, and serve.

Evidence: Strawberries are a source of vitamin C, but there are no direct studies here showing that strawberry juice increases hair growth. The drink’s nutrient content will depend on the fruit and how much pulp is removed.

5. Kiwi juice

Why consider it: Kiwi fruit provides vitamin C, which supports iron absorption from foods such as beans, tofu, and fortified grains. A kiwi drink can add variety to a diet, but it will not supply all the protein, iron, or other nutrients needed for normal hair growth.

How to use it: Peel and blend kiwi with water, then strain for a thinner drink. The yield and nutrient content will vary with the fruit and the amount of pulp removed.

• 80 g (1/2 cup) chopped, peeled kiwi
• 120 mL (1/2 cup) water

1. Wash the kiwi, peel it, and chop the flesh.
2. Blend with the water, strain through a clean sieve, and serve.

Evidence: Kiwi is a vitamin C source, but there is no direct evidence here that drinking kiwi juice improves hair growth. If you enjoy the fruit, eating it whole is an alternative that retains its fiber.

6. Spinach juice

Why consider it: Spinach provides folate and other nutrients involved in normal cell function. It also contains iron, but the amount that reaches a strained drink and is absorbed should not be assumed to meet your needs. Whole spinach or other iron-containing foods are a more dependable part of a balanced meal.

How to use it: Blend washed spinach with water and strain for a mild green juice. This is an occasional way to add greens, not a replacement for eating a variety of vegetables.

• 30 g (1 cup) loosely packed raw spinach
• 120 mL (1/2 cup) water

1. Wash the spinach thoroughly under running water.
2. Blend with the water, strain through a clean sieve, and serve.

Evidence: Spinach contains useful nutrients, but there is no direct evidence here that spinach juice promotes hair growth. Straining removes some plant material, so the drink should not be assumed to have the same nutritional content as the whole leaves.

How much juice should you drink for hair growth?

There is no evidence-based amount of juice recommended specifically for hair growth. A practical way to try a bottled juice is a 120 mL (1/2 cup) portion, with or without water, alongside a meal. This is a serving suggestion, not a dose shown to affect hair.

Choose 100% juice without added sugar when possible. Juice can provide vitamins, but it also contains natural sugars and usually has less fiber than whole produce. If you drink it regularly, keep it in proportion to the rest of your diet rather than replacing meals or several servings of whole fruit and vegetables with it.

For homemade juices, wash produce under running water, use clean equipment, and serve promptly. The fruit-and-water recipes above vary in yield; they should not be treated as nutritionally equivalent to a measured portion of bottled juice.

Who should be careful, and when should you see a doctor?

If you have diabetes or need to manage blood glucose, consider the carbohydrate in juice as part of your meal plan. If you have kidney disease or have been advised to limit potassium, ask your clinician or dietitian whether juices such as orange and tomato juice fit your needs. People taking warfarin should discuss their spinach intake with their clinician and keep vitamin K intake consistent; do not stop medication to accommodate a juice.

Pregnant people, young children, older adults, and people with weakened immune systems should choose pasteurized juice rather than unpasteurized juice, because harmful germs can remain in raw juice. If that applies to you, use pasteurized products instead of the raw homemade recipes above.

See a clinician for sudden, patchy, or persistent hair loss, or if hair loss comes with a painful, red, or scaly scalp. A clinician can look for possible causes, including nutritional deficiencies or medical conditions, and advise whether testing is appropriate. Avoid taking high-dose supplements for hair growth without advice; too much of some nutrients can be harmful.
