Eucalyptus and Hair Growth: Mechanism of Action

Eucalyptus and Hair Growth: Mechanism of Action

A robust scalp and hair care routine is essential for anyone concerned about scalp health and hair loss. Eucalyptus can help with scalp health hair loss symptoms, and it is one of the key ingredients found in Divi’s lineup of scalp care products. 


There are many causes of hair loss, including genetics, illness and even stress or trauma to the scalp. Taking the time to learn about some vital, clean ingredients can be an excellent way to minimize the risk of hair loss by first creating a healthy scalp.


This article will explore the benefits of eucalyptus oil found in Divi's Scalp Serum. You will learn more about why eucalyptus is chosen to complement the other high-quality ingredients in our products and understand how it can benefit your hair and scalp.


What is Eucalyptus Oil?

Eucalyptus oil is a genus native to Australia, with more than 700 flowering tree species under its umbrella.


Eucalyptus globulus is a species of eucalyptus tree found in southeastern Australia and is also known as ”Blue Gum.”


We use eucalyptus globulus oil in our Scalp Serum for its beneficial properties, including human hair follicle stimulation, improved hair and scalp health, and itchy scalp relief.


How Does Eucalyptus Facilitate Hair Growth?

Using hair care products containing eucalyptus oil is a significantly more accessible way to ensure your scalp gets the benefits of this ingredient without the inconvenience of having to get the correct dosages or mix it with a carrier oil.


Eucalyptus oil can improve the scalp's blood circulation. This promotes greater oxygenation and ensures hair follicles get the nutrients they need to flourish. Eucalyptus oil also helps regulate oil production on the scalp, minimizing the risk of conditions that arise from an oily scalp and hair.


This ingredient in our Scalp Serum can boost hair cortex growth and increase the beta-sheets in the hair growth cycle. All of this together has the potential to protect the scalp and hair from damaging oils, promote hair follicle health, and improve hair strength.


Which Conditions Can Eucalyptus Oil Help?

Eucalyptus oil can help a few hair and scalp conditions. We’ve listed the most common ones below:

  • Itching scalp – Eucalyptus oil is recognized for having properties that cool the skin and relieve itching. An itchy scalp is often the result of other conditions, and eucalyptus oil provides an excellent way to stimulate the scalp and improve its health.
  • Dry scalp – Eucalyptus oil is an excellent way to stop scalp dryness. Studies show that applying eucalyptus extract to the scalp can increase ceramide levels in human keratinocytes. This can improve the stratum corneum's water-holding abilities and help trap moisture in your hair strands.
  • Dandruff – Eucalyptus oil is a great way to treat dandruff thanks to its antifungal properties. One of the leading causes of dandruff is Malassezia, a fungus that feeds on scalp oils. Eucalyptus has been tested against fungi and is a successful antimicrobial against them.
  • Seborrheic dermatitis – Seborrheic dermatitis is a skin condition typically affecting the scalp and causing redness, scaly patches and dandruff. This skin condition occurs when the body's immune system reacts strongly to the overgrowth of yeast. Eucalyptus oil's antifungal properties help to remove Malassezia, minimizing the risk of the immune system overreacting, resulting in seborrheic dermatitis.
  • Folliculitis (non-bacterial) – There are many different types of folliculitis, and viral or fungal sources or parasitic microorganisms could cause non-bacterial versions. It appears as raised bumps around hair follicles that look similar to acne. The antifungal properties of eucalyptus can be a successful way to clear this condition.
  • Scalp psoriasis – Psoriasis is a skin condition that can appear like dandruff or leave scaly patches. Scalp psoriasis only applies to the scalp and is caused by allergens or immune dysfunction. Eucalyptus oil can help to cool and soothe itchy or uncomfortable cases, and studies show it produces anti-inflammatory and antiseptic benefits.
  • Scalp eczema – Scalp eczema is a form of atopic dermatitis that causes sore, cracked and itchy patches on the head. This condition can be triggered by drastic temperature changes, medication, external irritants, hormonal changes and stress. Moisturizing treatments are successful in the treatment of scalp eczema. Eucalyptus contains properties that can increase ceramides and help to trap moisture in your hair, which also helps stop the scalp from drying.
  • Allergic dermatitis - Allergic dermatitis affects people who come into contact with external stimuli to which they are allergic. Eucalyptus oil's anti-inflammatory properties will help reduce the redness or itchiness that can often come with a rash or allergic reaction.
  • Sensitive scalp – A hypersensitive scalp can be uncomfortable and painful. Causes include psoriasis, other conditions, migraines, sunburn, rashes and more. Massaging the scalp has been shown to reduce symptoms, and finding a way to cool the scalp can also help. Eucalyptus oil’s anti-inflammatory properties can soothe a sensitive scalp and help to reduce the burning or tingling sensation.
  • Male-pattern baldness - While Divi's Scalp Serum won't stop male-pattern hair loss, the ingredients can help create the best conditions to promote hair growth and slow or minimize its impact. Eucalyptus has been shown to improve the scalp's blood circulation. This allows oxygenation and provides the hair follicles with the nutrients for healthy hair growth promotion. Divi’s lineup of products contains several other essential oils that promote growth and improves hair, scalp and follicle health.
  • Thinning hair – Divi's Scalp Serum makes use of several ingredients shown to stimulate hair growth. Plant essential oils like eucalyptus often provide an excellent way to care for hair follicles, the scalp and hair. Eucalyptus can improve circulation, which can improve hair growth by allowing hair shafts and follicles to get the nutrients required for the anagen stage of the hair growth cycle.
  • Female-pattern hair loss – Female-pattern hair loss is surprisingly common. While hair loss is more associated with men, many women suffer from thinning hair at different stages of their life. As with male-pattern hair loss, using the correct ingredients in scalp care products can help stimulate hair growth and improve the health of hair follicles. Eucalyptus is a crucial ingredient in Divi's Scalp Serum. It works with other ingredients to provide a high-quality hair care routine that can prolong the anagen stage of the hair cycle and improve hair thickness for women.
  • Lichen planopilaris – Lichen planopilaris is an inflammatory autoimmune disease that can result in follicular hyperkeratosis and, in some cases, permanent hair loss. Applying eucalyptus to the affected areas can help to soothe it, thanks to its anti-inflammatory properties.
  • Trichotillomania – Trichotillomania is the process of pulling hair from your head. This can be a result of anxiety or stress. While eucalyptus won't stop someone from pulling hair from their head, it can help to soothe the area.

Can Too Much Eucalyptus Affect Hair Follicle Growth?

Too much eucalyptus oil can irritate your scalp. However, there's no need to worry about this when using Divi's Scalp Serum, as we blend the perfect dosages of clean ingredients to make it a safe product.

Possible Side Effects of Eucalyptus Oil

Our Scalp Serum is dermatologically tested to ensure it carries none of the risks associated with undiluted or ingested eucalyptus oil. In other words, put our Scalp Serum on your head, not in your mouth!


Final Thoughts

Many essential oils can benefit hair health. Taking the time to explore products containing them and their benefits can help improve hair health and minimize the risk of hair loss.


While hair loss may be avoidable in some cases, using ingredients like eucalyptus oil can help provide the hair health needed to delay thinning. Divi's Scalp Serum contains a range of high-quality, clean ingredients, and eucalyptus oil is an excellent example of one with the potential to improve your hair, scalp and follicle health.
