Benefits of Eucalyptus for Treating Hair Loss and Scalp Irritation

If you have ever used an aromatic chest rub when your sinuses and nose are congested, you're probably familiar with the smell of eucalyptus oil. The uses of eucalyptus oil, which comes from a tree, go far beyond its fresh and distinctive scent, however, and you don't have to be a koala bear to benefit from it (though the animals certainly find it delicious)!

People have known about the medicinal and antimicrobial properties of eucalyptus for centuries, and it has been a staple in the hair care, health, and beauty industries for decades. In particular, scientists have spent a lot of time researching eucalyptus's benefits for treating hair loss. 

Sure, eucalyptus has antimicrobial properties, but how does this help stimulate hair growth? And why is it so effective? Our team of scalp experts at Divi explores the answers to these questions – and more – in this article.

The Effects of Eucalyptus Oil on the Human Body

Did you know that there are more than 700 species of eucalyptus trees worldwide? Most of these trees are native to Australia. The primary compound in eucalyptus oil is called eucalyptol, and it is an effective ingredient in anything from insect repellent to disinfectant. Divi's Scalp Serum uses the essential oil from the Eucalyptus globulus tree to achieve a wide variety of effects that can help you combat hair loss.

Many people prize eucalyptus oil for its anti-inflammatory properties. Its potential to help soothe an itchy, inflamed scalp is well-known. When you apply it to your skin as part of a well-researched hair care formula, eucalyptus oil can help reduce inflammatory reactions by suppressing the degranulation of mast cells. Reducing the level of scalp inflammation helps decrease itchiness and protect your hair follicles, fostering a great environment for healthy hair growth.

Topical application of formulas containing eucalyptus oil has been shown to increase the amount of ceramide your skin produces. This can help slow down the hair loss that comes with the aging process. As a result, treating your scalp and hair with a eucalyptus-infused product such as Divi's Scalp Serum daily can noticeably increase the bounce and luster of your hair strands.

In addition, eucalyptus oil is a highly effective astringent; it can help tighten soft tissue and reduce inflammation. Unlike harsher chemical astringents, however, it reduces the flakiness of your scalp while helping keep it moisturized.

What Benefits Does Eucalyptus Have for Treating Hair Loss?

Every case of hair loss is unique, and there are a lot of potential reasons that your hair might be falling out. However, one of the most common causes of hair loss is called androgenetic alopecia (which is also called AGA or male- or female-pattern hair loss). This form of hair loss is hormonal, and it happens when your body produces too much of a hormone called dihydrotestosterone (or DHT). Nearly 70% of men and 25% of women in one 2013 study had symptoms of this form of hair loss.

Eucalyptus oil does not cure the root causes of androgenetic alopecia. However, it can lengthen the crucial anagen phase, which is the stage for each hair when the follicle is actively adding to its length. Lengthening the anagen phase can help to maximize hair growth, and reduce the appearance of hair loss. Additionally, eucalyptus oil's anti-inflammatory properties can increase the flow of blood to your scalp, further encouraging healthy hair growth by bringing plenty of oxygen and nutrients to the roots of your hair.

Eucalyptus Oil Benefits For Scalp Inflammation

When it comes to clean ways to promote the overall health of your scalp, eucalyptus oil is hard to match. Suppose you are dealing with the effects of inflammatory hair loss — including that caused by eczema, psoriasis, allergic dermatitis, or seborrheic dermatitis. In that case, it may be worth adding a product containing eucalyptus oil, such as Divi's Scalp Serum, to your daily hair care routine.

The Positive Impact of Eucalyptus on Hair Growth

Eucalyptus essential oil certainly packs quite a punch for promoting healthy hair growth. The anti-inflammatory properties we mentioned are particularly beneficial, as scalp inflammation is one of the leading causes of hair loss in both men and women. While hormones are often the root cause of pattern hair loss, this hormonal imbalance causes an inflammatory response in your body. Treating the effects of that inflammation is one way to combat the symptoms of hair loss.

Eucalyptus oil is proven to be effective at lengthening the anagen (or growth) phase of your hair follicles. In the anagen phase, your hair follicle is focused on adding to the hair shaft that it supports. At any given time, about 90% of your hair is in this anagen phase, which lasts between three and five years before transitioning to the catagen (or transitional) phase, where hair growth stops. The last step is called the telogen phase, and this is when your hair naturally falls out. Extending the length of the anagen phase can lead to thicker, longer hair.

How To Apply Divi's Scalp Serum Containing Eucalyptus Oil

Whether you want to use eucalyptus oil to keep your scalp healthy and improve the quality of your existing hair or to regrow hair after it has fallen out, there are a few ways to optimize its effectiveness. Rather than using it in full concentration on its own, we recommend buying a scientifically formulated product like Divi's Scalp Serum to ensure the proper dosage. If you use Divi's Scalp Serum, you'll get the benefits of all the other clinically proven ingredients as well.

The combination of ingredients in Divi's Scalp Serum — including peptides, amino acids, vitamins, caffeine and other essential oils — is a great way to deliver eucalyptus oil to your hair and scalp. It is straightforward to use:

  • Shake the bottle well before use.
  • Apply ¾ of a dropper to your scalp once a day.
  • Massage it in, focusing on any particular problem areas. 

You can use it any time of day and don't need to worry about rinsing it out. Your bottle should last at least 30 days.

Potential Side Effects of Eucalyptus

Eucalyptus is one of the safest oils that you can apply topically. The most common negative effect of eucalyptus oil is an allergic reaction. The symptoms of eucalyptus allergy include hives, itching, redness and rash. You should also avoid using eucalyptus oil if you are allergic to tea tree oil, as the two plants are closely related to each other. Cross-reactivity between the oils is common.

That said, Divi’s Scalp Serum includes safe quantities of eucalyptus oil and has been dermatologically tested for topical application. The topical application of eucalyptus oil as part of Divi's formula has minimal risk of causing complications.

Our ingredients are clean, vegan-friendly, and backed by science.

We always recommend patch-testing any new product, and if you have an adverse reaction, we advise that you discontinue use and consult your doctor.

Other Ingredients in Divi's Scalp Serum That Promote Healthy Hair

The proprietary suite of clean ingredients we include in Divi's Scalp Serum work together to:

  • Improve the thickness and structure of your hair
  • Add sleekness, strength and shine to any hair type
  • Lengthen your hair's growth cycle
  • Stimulate the flow of oxygenated blood to your scalp

When you select any hair care product, you should consider how the ingredients work together to help achieve your hair goals. This section discusses some of the most effective ingredients for promoting hair growth.


You don't have to drink your caffeine to see its benefits! When you apply it topically, caffeine has been shown to inhibit the production of DHT in your body, reducing the effects of androgenetic alopecia. Its stimulant effects also promote blood flow to your hair follicles and can even thicken hair.

Copper Tripeptide-1 (GHK-Cu)

In addition to promoting blood flow in the scalp, copper tripeptide-1 has been shown to increase the levels of collagen and elastin when you apply it topically. This peptide is a set of three amino acids joined to a copper compound, and its healing properties can also extend the anagen phase of your hair follicles.

In addition, copper binds with melanin (the pigment that gives your skin and hair their color). This means that having copper tripeptide-1 as part of your daily scalp serum treatment may even help keep your hair from turning gray.

Green Tea Leaf Extract

Divi's Scalp Serum utilizes green tea leaf extract for a few reasons. First, the tea leaf contains epigallocatechin gallate (EGCG), a powerful antioxidant that can help reverse the hair loss that androgenetic alopecia causes

EGCG can also increase blood flow to the scalp, promoting the creation of new hair follicles and shortening the telogen phase (or shedding phase) of hair growth.

Peppermint Oil

It isn't just the eucalyptus oil that gives Divi's Scalp Serum its signature cooling tingle! We also add peppermint (Mentha piperita) oil to our hair products because it helps to soothe scalp irritation and promote the healthy growth of new hair.

A 2014 study in South Korea showed that topical application of peppermint oil was at least as effective as treatment with the drug minoxidil, and it carries fewer negative side effects than prescription hair loss drugs. The oil's cooling properties also make it an ideal treatment for the scalp irritation that many skin issues (including psoriasis and eczema) can cause.

Tea Tree Oil

Tea tree oil comes from the Melaleuca alternifolia tree, which (like eucalyptus) is a native of Australia. While many people use it as an aromatic, it also has a variety of antibacterial and antifungal properties. In 2013, a study showed that tea tree oil applied to the scalp could enhance the effects of minoxidil therapy when treating androgenetic alopecia.

Rosemary Leaf Extract

Rosemary (or Rosmarinus officinalis L.) may be a staple in your kitchen, but Divi's Scalp Serum uses it for a completely different purpose. People have prized this herb's medicinal properties for centuries, and in recent years, scientists discovered that the extract could be as effective as minoxidil when treating androgenetic alopecia. Unlike minoxidil, rosemary extract is unlikely to cause dryness and itchiness on the scalp, making it a superior option for many people with sensitive skin.

Rosemary oil works best when combined with other ingredients (such as the ones listed in this post). The longer you let it sit on your scalp, the better results you will see, so a rinse-free product like Divi’s Scalp Serum is particularly effective.


Anyone who has ever applied a cooling muscle rub to their aching muscles understands the power of menthol. It has been reported that menthol can act as a vasodilator. By helping to dilate your blood vessels, menthol increases blood flow through your scalp and can enhance new hair growth. In addition, menthol's antimicrobial and antifungal properties make it a great way to keep your scalp healthy and clean.
