Onions for growth, spinach for colour and garlic for strength: The raw juices that promise to boost your hair

Raw juices help lock in nutrients which are essential for healthy hair
Antioxidant in kiwi fruit helps to protect follicles and encourages growth
Coriander combats stress, which is one of the causes of hair shedding
Consuming raw vegetables, alliums and certain fruit in juice form is the best way to ensure your hair is glossy and healthy, experts say.

Garlic, onion, spinach, coriander and aloe vera contain nutrients that help growth, protect follicles, and combat hair loss.
Here nutritionists Cassandra Barns and Shona Wilkinson tell FEMAIL why incorporating these 12 juices to your diet will keep your locks healthy, glossy and strong.
Of course, vitamin C is also essential for the immune system, and as we’ve already seen, when the immune system is properly balanced it is less likely to react against the hair follicles. Like many other colourful fruits, kiwi fruits also contain a wide variety of flavonoids and carotenoids, which can also act as antioxidants. Kiwi fruits also contain small amounts of copper, a mineral that is known to contribute to hair pigmentation.

GUAVA

Guavas are one of the best sources of vitamin C, containing more than double that found in kiwi fruits! As we saw when looking at kiwi juice, vitamin C may not have a known direct role in hair growth, but it does act as an antioxidant and supports the immune system, potentially helping to protect the hair follicles. Guavas, like papaya, are said to be particularly rich in the antioxidant carotenoids lycopene, lutein and cryptoxanthin which may also have a protective effect.

GARLIC

Garlic has a strong anti-bacterial and anti-fungal effect. As hair loss can result from an infection of the skin or hair follicles, applying garlic juice to the scalp could be very effective at bringing any infections under control and restoring balance.

Garlic is also a good source of the mineral selenium, another important mineral for healthy hair. You’d have to eat a lot of garlic to get a meaningful amount, but the amounts in a juice are likely to be more concentrated!

CUCUMBER

Cucumber again contains antioxidant nutrients such as vitamin C, manganese and beta carotene, as well as a number of flavonoids, all of which may help to protect the hair follicles.

Cucumbers are also said to be a good source of silica, a mineral that is found in our connective tissues and may help to support hair growth.
CORIANDER

Like spinach, coriander is a source of iron, which can help to prevent the iron deficiency that typically leads to hair loss in women.

It’s also a source of copper, which is needed for hair pigmentation, and manganese, which has antioxidant activity; and contains a wide variety of flavonoids and carotenoids.

Coriander is sometimes said to have stress-relieving properties too - stress is another common cause of hair loss, so anything we do to relieve it can only be helpful!

ALOE VERA

Aloe vera is well-known for supporting the skin, with its healing and soothing action. Many people also swear by drinking aloe vera juice for improving the growth and condition of their hair. However, how it works for the hair is not clear.

It may simply be due to the vitamins and minerals contained in the juice, which are said to include vitamins C, E and beta carotene (a precursor to vitamin A) as well as vitamins B1, B2, B3 and B6 and the minerals zinc, copper and iron.

Another way it could work is by supporting the immune system. In some cases, hair loss is thought to be due to an immune reaction against the hair follicles, indicating that the immune system is out of balance.

Aloe vera juice contains a substance called acemannan that may help to balance and support the immune system.
CARROT

Like onions, carrots are one of the best sources of biotin, a vitamin that is essential for normal hair growth. 100g of carrots contains around 20 per cent of our recommended intake of biotin, so making a fresh juice with a whole bag of carrots could easily give you a full daily quota!

Of course, carrots are also rich in antioxidant carotenoids, and they provide huge amounts of beta carotene, which can be converted into vitamin A in the body - a vital nutrient for immune system balance.

STRAWBERRY

Strawberries are another fruit that is very rich in vitamin C. In fact, they can contain more than any other berry. Vitamin C acts as an antioxidant and supports the immune system, helping to protect the hair follicles.

Like most berries, they contain a wide selection of antioxidant flavonoids and specifically anthocyanins, which give them their brilliant colour.

ONION

One of the nutritional highlights of onions is that they are rich in biotin, a vitamin that is essential for normal hair growth.

Like kiwi fruits, onions also contain some copper to support hair pigmentation, and they’re a fantastic source of flavonoids - especially quercetin - that have antioxidant effects.

Substances in onion, including quercetin, have also been found to have antibacterial activity, and this may help to control or eliminate infections of the skin or hair follicles if fresh onion juice is applied to the scalp.

SPINACH

Spinach is a good source of iron. This is particularly important as iron deficiency is a common cause of hair shedding in women - a type of hair loss called ‘chronic telogen effluvium’.

Spinach is also a good source of a variety of vitamins and minerals including vitamin K, vitamin C, folate, manganese, magnesium, copper and beta carotene (the precursor to vitamin A), and is rich in flavonoids and carotenoids that act as antioxidants.
