Does green juice help hair growth?

Green juice has become a popular health trend in recent years. Made by juicing leafy greens and vegetables, green juice is chock-full of vitamins, minerals, and antioxidants. Some people drink green juice to lose weight, improve skin health, or increase energy. But can gulping down kale, spinach, and other greens really help your hair grow faster and healthier?

Many natural health advocates say yes. Green juice contains nutrients that may promote hair growth, including iron, vitamin C, vitamin A, vitamin E, B vitamins, zinc, and biotin. Deficiencies in some of these nutrients have been linked to hair loss and slowed hair growth.

Green juice also provides antioxidants that can protect hair follicles and strengthen strands from within. Certain ingredients like ginger and cinnamon may also stimulate circulation to the scalp, bringing more blood flow to hair follicles.

While the specific benefits of green juice for hair are still unclear, adding more vitamins and minerals to your diet likely won’t hurt. But downing a daily green juice alone won’t magically give you long, lush locks. Read on to learn whether green juice lives up to the hype for hair growth.

The Nutrients in Green Juice

Here’s a look at some of the key nutrients found in green juice and why they matter for your hair:


Iron carries oxygen to your cells and aids hair follicle growth and repair. Iron deficiency is a major cause of hair loss, particularly in women. Foods like spinach, kale, broccoli, and swiss chard are excellent plant-based sources of iron.

Vitamin C

Vitamin C helps you absorb iron more efficiently. It also boosts collagen production, supplies antioxidants, and supports hair follicle health. Green juice ingredients high in vitamin C include kale, parsley, broccoli, and green bell peppers.

Vitamin A

Vitamin A helps make sebum, the oily substance secreted by your hair follicles. Sebum keeps your scalp moisturized and conditioned for healthy hair growth. Spinach, carrots, sweet potatoes, and peppers provide vitamin A in green juice.

Vitamin E

Vitamin E stimulates circulation in the scalp to foster hair growth. This powerful antioxidant also protects hair follicles from damage and may help reverse graying. Spinach, broccoli, avocado, and Swiss chard supply vitamin E in green juices.

B Vitamins

B vitamins nourish hair follicles and may slow hair loss. Specific B vitamins like biotin, niacin (B3), pantothenic acid (B5), pyridoxine (B6), and folate (B9) contribute to healthy hair. Green veggies that provide B vitamins include spinach, broccoli, kale, asparagus, and green peas.


Zinc deficiency can trigger hair loss and affect hair protein structure. Pumpkin seeds, one of the only green juice ingredients with zinc, are often added to juices for this key mineral.


Also known as vitamin B7, biotin is crucial for hair, skin and nail health. Insufficient biotin levels can cause brittle hair. Avocado, spinach, and Swiss chard provide biotin in green juices.

Other Benefits of Green Juice for Hair

In addition to vitamins and minerals, green juice contains other beneficial compounds that may support hair growth:


Antioxidants like lutein, zeaxanthin, and beta-carotene counteract damage from free radicals that can impair hair growth. Kale, spinach, parsley, broccoli, carrots and peppers are antioxidant-rich green juice ingredients.

Amino Acids

Amino acids like lysine, arginine, and methionine make up proteins that form hair. While green juice is low in protein, small amounts of amino acids are present.

Anti-Inflammatory Compounds

Green juice often contains ginger, turmeric, mint, basil, and other anti-inflammatory compounds. They help reduce scalp inflammation that can inhibit hair growth.


Plant chemicals like luteolin, apigenin, and quercetin in green juice have antioxidant, anti-inflammatory effects that may promote hair health.

Green Juice Ingredients that Support Hair Growth

Certain green juice ingredients are particularly good for your hair. Here are some top picks:


Spinach is loaded with iron, folate, vitamins A and C, zinc, and selenium to nourish hair follicles and strands.


Kale provides vitamins A, C, and K, plus copper and potassium. It helps boost collagen production for healthy hair growth.


Parsley is rich in vitamins K, C, and A, plus folate and iron. It brings antioxidants like luteolin and apigenin.


Cucumbers contain vitamin C, caffeic acid, silica, and sterols to potentially stimulate hair growth and slow loss.


Ginger improves circulation to the scalp. It also has anti-inflammatory benefits for hair follicles.

Aloe Vera

Aloe vera gel provides vitamins, minerals, and compounds that may strengthen hair follicles and enhance growth.

Research on Green Juice and Hair Growth

While green juice contains many healthy hair nutrients, there is limited direct research on green juicing and hair growth. However, studies have found benefits from some key ingredients:

  • In one study, taking iron supplements for 6 months reversed hair loss in women with iron-deficiency anemia.
  • Biotin supplements helped increase hair thickness and improved symptoms of hair loss in people with biotin deficiency in one study.
  • Spinach extracts boosted hair growth similar to minoxidil in lab and animal studies.
  • Onion juice applied topically significantly increased hair regrowth over 6 weeks in one study.
  • Ginger extracts enhanced hair growth in wound healing tests on rats.

While this research is promising, more studies are needed to determine whether juicing greens can prevent hair loss or enable faster hair growth.

Should You Use Green Juice for Hair Growth?

While the idea of improving hair health with nutrient-packed green juice is appealing, there are some important caveats:

  • Green juice lacks protein, an essential hair nutrient. Make sure to also eat high protein foods like eggs, meat, fish, dairy, beans, nuts, and seeds.
  • Some key hair nutrients like biotin and zinc are found only in very small amounts in green vegetables. Consider taking a supplement to get enough.
  • Drinking only juice leaves out valuable fiber from whole fruits and vegetables that benefits hair.
  • It’s unclear how much green juice nutrients are absorbed compared to eating solid foods.
  • Green juice is not a magic bullet for hair growth. A healthy, balanced diet is most important.

With these precautions in mind, adding a daily green juice to your routine may support hair health alongside other lifestyle measures like:

  • Eating protein, healthy fats, fruits, vegetables, and whole grains
  • Taking targeted supplements like iron, biotin, zinc, etc. if deficient
  • Reducing stress
  • Treating hair disorders and conditions
  • Using hair-friendly styling practices


Green juice provides a concentrated dose of vitamins, minerals, and antioxidants that may benefit hair growth. Nutrients like iron, biotin, vitamin C, and vitamin A are especially helpful for healthy locks.

Some ingredients like spinach, kale, cucumber, parsley, and ginger stand out for their hair perks. Early research also indicates promising effects on hair from greens.

However, green juice has some drawbacks when it comes to hair health. Make sure to also eat complete protein sources and consider supplements to meet your daily needs.

While more research is required, incorporating green juice into a balanced diet and lifestyle may support and strengthen your hair over time. Drink up for the potential hair benefits from all those vitamins and minerals!
