Green Tea Extract Benefits for Treating Hair Loss Studies & Data

Drinking green tea has amazing health benefits, but are you aware that topical application of green tea extract can also have benefits for the health of your scalp and hair?

Divi’s Scalp Serum includes green tea as a key ingredient to promote hair regrowth by improving scalp health – the key to healthy hair.

Here, the team will show you how hair products containing green tea can benefit people suffering from hair loss or baldness.

Do Studies Support Green Tea Extract as a Treatment for Hair Loss?

The hormone testosterone is related to hair loss because it shrinks hair follicles, which prevents hair production. A number of studies have found connections between green tea, testosterone inhibition and hair growth or loss. 

A study published in Case Reports of Dermatological Medicine looked at how an active constituent of green tea – epigallocatechin-3-gallate (EGCG) – suppresses an active form of testosterone called DHT. DHT inhibits hair growth and by suppressing it, its hair loss effects are neutralized.

Another study published in the Journal of Cosmetic Dermatology supports these findings, concluding that EGCG inhibits the effect of testosterone, thereby slowing hair loss.

A pilot study that included 10 individuals with androgenetic alopecia (male or female pattern baldness) had participants take a supplement containing green tea extract, among other ingredients, for the duration of the study. After 24 weeks, 8 of the 10 participants experienced improved hair growth. 

Topical application of ECGC has also been shown to significantly reduce testosterone-induced hair loss in mice. There is clear scientific evidence that EGCG-rich green tea extract reduces hair loss caused by testosterone.

Can Green Tea Extract Benefit Your Hair and Scalp?

In addition to EGCG, green tea also contains many vitamins, minerals and natural stimulants that provide an advantage to hair and scalp health. Some of these ingredients include:

  • A range of B vitamins, which are important for promoting hair growth
  • Calcium and iron, which help hair retain its color
  • Caffeine, which increases blood flow and carries nutrients to your scalp (as an added bonus, Divi’s Scalp Serum also contains caffeine separately, further boosting this effect)

Symptoms Green Tea Extract Can Help With

Hair Loss

The active components in green tea inhibit the production of DHT, a hormone derived from testosterone that is associated with hair loss. 

Oily Hair

Green tea can help decrease oil production.

Dandruff or Dry Scalp

Green tea is an excellent anti-inflammatory ingredient and can help with a variety of scalp problems such as dandruff, psoriasis or eczema. It moisturizes and softens the skin on the scalp, which reduces inflammation.

Green tea is also a potent antifungal agent, and topical application can help treat dandruff caused by fungus on the scalp.

Dull Hair

By contributing to the maintenance of a healthy scalp, green tea extract can also ensure that hair looks healthy and has a shine to it. Topical treatments, like Divi’s Scalp Serum, feed the hair from the follicle, which encourages the growth of strong, healthy hair.

Is Green Tea Extract Safe for the Scalp?

Like all the ingredients in Divi’s products, green tea extract is safe for the scalp. It can be found in all three of our products – Shampoo, Conditioner and Scalp Serum. Although Divi’s products are made of clean, dermatologically tested ingredients, we recommend you always test a small patch first to check for any irritation.

Does Green Tea Extract Treat Hair Loss?

Green tea extract supports healthy hair growth and reduces hair loss by inhibiting the hormones that cause hair loss. It also stimulates blood flow to the scalp. This ensures that hair receives all the nutrients it needs for a healthy scalp, which is an important part of hair growth.

Hair Loss and Androgenetic Alopecia Explained

Androgenetic alopecia accounts for 95% of male pattern baldness. This condition is caused by the hormone dihydrotestosterone (DHT), which inhibits hair growth activity and results in hair loss. DHT is active in men who have a genetic tendency for pattern baldness. Therefore, androgenetic alopecia is a genetic hair loss condition. It can also happen for women, although not as common.

DHT causes hair loss by binding to receptors on the hair follicles. This causes the follicle to shrink, preventing further hair production.

Common Causes of Hair Loss


Most people notice their hair strands thinning with age. As people age, cells die off faster than they can regenerate, causing thinner hair, less oil production and an increase in hair loss.

Changes in hormones

Your hair’s natural growth cycle is impacted by hormones, and conditions or lifestyle changes can cause hair loss. These changes include:

  • Polycystic ovary syndrome (PCOS)
  • Congenital adrenal hyperplasia
  • Pregnancy
  • Menopause
  • Hypothyroidism


Whether ongoing or acute, stress can cause hair to fall out. This occurrence is medically known as telogen effluvium. It is not a permanent condition and will go away with time, as the stress reduces.

Dietary Deficiencies

Chronic telogen effluvium can happen when a diet is lacking in iron, zinc and vitamin D. Topical treatment of ingredients containing these nutrients and including supplements in your diet can help replenish them to healthy levels.

Autoimmune Disorders

Occasionally, autoimmune disorders, such as alopecia areata, can cause the body’s immune system to attack hair follicles. This is linked to an autoimmune response triggered by stress.


Yeast, fungal and bacterial infections can all attack the base of the hair strand and follicle, causing hair to fall out.


Several medications have hair loss as a side effect. This is especially common with cholesterol and blood pressure medications, plus chemotherapy for cancer.

Hair Styling

Extreme hair styling can destroy hair follicles and prevent hair regrowth due to inflammation in the scalp. Chemical hair treatment, heat styling or constant tight hairstyles can all contribute to permanent hair loss.
