Tea Tree is a Must-Have for Monsoon Haircare: Here’s Why?

Almost 75% of the people around the world face increased hair loss during the monsoons! Increased moisture in the air, sweat production and air pollution often lead to problems like dandruff, irritation of the scalp, excessive production of oil, frizz and finally hair loss. 

As the world is making a transition to natural and safe formulations for addressing beauty and wellbeing concerns, tea tree oil emerged as an immediate care option for safeguarding the strands. This natural oil offers a wide range of care ranging from fighting dandruff to controlling the excess oil while balancing the scalp pH for enabling a healthy scalp environment. 

So, without any further delay, let’s understand how tea tree is an essential element of monsoon haircare!

Tea Tree oil is a natural botanical that is derived from the leaves of the tea tree plant, which is commonly known as Melaleuca alternifolia, which are mostly found in the wetlands of New South Wales and Queensland, Australia (Carson, Hammer and Riley, 2006). It is an essential oil that is widely used in the holistic aromatherapy practices for common wellbeing of the skin and hair. The oil is produced through a process called the steam distillation, where steam is passed through the leaves of the plant and the aromatic compounds are thereby collected and condensed to form the liquid, oil-like texture.

• Australian Indigenous Aboriginal:

Tea tree has been used for over thousands of years and is used by Indigenous Australian Aboriginal as a remedy for treating coughs, colds, minor skin ailments and infected wounds (Ebrahimi et al., 2026). Later in the 1770s Captain James Cook observed the scent produced from boiling the leaves by the Indigenous people and found a strange resemblance of the aroma to nutmeg (Olsen, 2003). This discovery led the explorer to coin the term “tea tree” while his crew brewed the leaves as a tea substitute. 

• Early 20^th Century:

The famous Australian chemist Arthur Penfold officially documented tea tree oil’s germicidal properties in the year 1920s (Britannica, 2026). Later, inspired by the oil’s germicidal and antiseptic properties the Australian government introduced it as a standard component in the first aid kits of Australian soldiers during World War II. The move helped in improving the scope of topical wound treatment (Kalaraoil, 2026). 

• Modern Day Adaptations:

As the global interest for plant-based and natural ingredients attained peak demand in the 1960s and 1970s the tea tree oil was first introduced as over-the-counter remedy for its natural anti-inflammatory and germicidal properties (Lahkar, Das and Bora, 2013). Today, the essential oil is mostly used as a health and wellbeing remedy in various formulations like soaps, lotions, hair and skin care solutions etc.  

Tea tree oil contains a combination of over 100 active components, but some of the major components that helps with appropriate hair care are terpinen-4-ol, γ-terpinene, α-terpinene and 1,8-cineole. The inclusion of these powerful components has largely contributed to the oil’s antibacterial, antifungal and anti-inflammatory properties. 

Here’s how the components work:  

• Terpinen-4-ol: 

This particular component makes up almost about 35% to 48% of the tea tree oil and is thereby the primary active ingredient. With antiseptic, antibacterial, and anti-inflammatory properties the component fights the causes of root causes of dandruff directly by inhibiting the growth of the fungus Malassezia, keeping the scalp clean and healthy (Mondello et al., 2022). 

• γ-Terpinene (Gamma-terpinene): 

It comprises of 10% to 28% of the oil, and acts as a potential antioxidant that protects the scalp against radical attacks while its skin soothing properties calms scalp irritation (Hammer, Carson and Riley, 2003). So, this component helps in reducing inflammation in the scalp while reducing irritation, itchiness and subtle discomfort. 

• α-Terpinene (Alpha-terpinene): 

The component makes up almost 5% to 13% of the oil and is well-known to boost hair growth. The component provides effective antioxidant support while stimulating the pathways for healthy hair growth, thereby promoting fuller appearance on the scalp (Astani, Reichling and Schnitzler, 2010). 

• 1,8-Cineole (Eucalyptol): 

This component is present in the oil in traceable amounts up to 15%. The calming and soothing properties of this component contributes to tea tree oils soothing and cooling effects on the scalp (Hoch et al., 2023). Also with insecticidal properties, the component reinforces the capability of the oil in naturally paralyzing and killing lice, promoting clear and healthy scalp environment for consistent hair growth.  

• Fungal and Bacterial Overgrowth: 

In the rainy season, the scalp is usually warm, moist, and humid, which provides a perfect environment for the development of fungi and bacteria. It leads to the formation of microorganisms such as Malassezia, which may upset the balance of the scalp and cause conditions such as dandruff, scalp itching, folliculitis, seborrheic dermatitis, and inflammation (Martínez-Ortega, Quej and González, 2024).

• Excess Oil and Clogged Follicles: 

Humid air causes an increase in sebum (oil) production from the glands in the scalp. When this excess oil mixes with sweat and environmental contaminants, a sticky and greasy substance is created which blocks the hair follicles and deprive the scalp of oxygen (Pedroja, 2023). Over a period of time, the scalp grows weak while it starts affecting normal hair growth. 

• Swelling and Breakage: 

During humid conditions, the hair strands tend to soak up moisture, resulting in the expansion of the hair shaft. The constant expansion weakens the hair strands, which leads to hair becoming brittle, weak and vulnerable to damage, including breaking and splitting (Cherney, 2026).

• Extreme Frizz and Loss of Definition: 

With a subtle increase in moisture content, the hair shaft puffs up and makes the cuticle surface irregular. Hair loses its smoothness and original shape due to the presence of moisture. This results in frizzy and unmanageable hair (Marie, 2021).

• Acid Rain and Pollution Damage: 

The rainwater in urban settings usually carries pollutants, dust particles, and chemicals from the air. This has the ability to strip away the moisture content from hair while affecting the hair barrier. The complete phenomenon leaves the hair dry, rough and lifeless.

• Damage from Constant Dampness: 

The hair becomes weak when wet due to elasticity and the vulnerability of the strands to stress. The extended period that hair remains wet starts weakening the roots, tangles the hair and increases hair fragility that leads to perpetual loss (ABP, 2026).  

• Fights Monsoon Dandruff and Fungal Infections:

Humidity during the monsoons traps moisture content to the scalp, resulting in a moist and warm environment where fungus and yeast (Malassezia yeast) flourish quickly. This is one of the reasons for flaky dandruff and infection, as well as continuous itching during the rainy season. Being rich in terpinen-4-ol and the antifungal and antimicrobial properties, Tea tree oil acts on the microbes causing the infection, thereby clearing the infection causing agents from the roots (Mahizan et al., 2019). 

• Soothes Itchy, Inflamed Scalps:

Exposure to dampness or humidity for a longer span of time and excessive sweating causes irritation to the scalp skin surface. This irritation in the scalp is often accompanied by redness and inflammation, followed by itching sensations that increase with scratching (Bin Saif, Ericson and Yosipovitch, 2011). However, the anti-inflammatory and anti-septic nature of the tea tree oil is used in combination to help soothe this irritation, resulting in a cool feeling that helps reduce redness and irritation while preventing any future microbial irritation.

• Controls Excess Sebum (Oil): 

Humid and hot weather during the rainy seasons might often overstimulate the oil producing glands on the scalp, making them produce excessive oil that makes the hair look greasy and lifeless soon after a wash (Mahizan et al., 2019). The natural astringent and scalp balancing properties of Tea tree oil regulates sebum production and cleanses the pores as well as the hair follicles deeply as a measure of controlling the sebum production and preventing the greasy feel on the scalp (Jewell, 2019). 

• Unclogs Hair Follicles: 

The combination of excessive sweating along with high monsoon humidity means that there is an accumulation of particulate matter, dead skin cells and even residues from hair products at the roots, leading to follicle clogging and lack of oxygen and nutrition reaching the hair follicles. In the long run, such follicle clogging results in weakening of the hair at its root and faster loss of hair and reduced hair growth. Tea tree oil helps in clearing the pores while improving scalp circulation, thereby boosting hair growth.  

• Tea Tree Essential Oil: 

A multipurpose-purpose pure essential oil that is derived from the healing power of Tea Tree. It is meant to cleanse, protect and rejuvenate the scalp and the hair. The cleansing and scalp soothing qualities allow it to help promote healthy hair by improving blood flow, balancing scalp pH and cleansing the scalp of dandruff while cleansing the pores. 

• Rosemary, Teatree and Coconut Hair Care Kit: 

An advanced hair care treatment that includes the strength of Rosemary along with the purifying effect of Tea Tree for the entire hair care process. This is designed to reduce hair fall, relieve irritation of the scalp, remove flakes and provide deep conditioning to dry hair. 

• Scalp Care- Shampoo and Solution: 

Combat stubborn dandruff and scalp irritation with advanced Tea Tree-based shampoo and solution combo. This complete solution kit helps cleanse the scalp, prevent flakes, stop itching and maintain scalp health for healthy hair growth. 

• Coconut-Teatree Oil: 

A potent combination of Tea Tree and Cold Pressed Coconut Oil that is ideal for taking care of the scalp and hair. With 1% tea tree and 99% virgin coconut extracts this advanced hair oil keeps the scalp clean and soothed, while moisturizing and strengthening the strands from root to tip.  

The rainy season can be particularly challenging as quite often it requires people to deal with concerns like dandruff, excess oil, itchiness, frizz and hair fall. Although the season can be quite refreshing for some, but for others the season puts an end to haircare and calls for some extra attention. The humid weather and the increased moisture content in the atmosphere catastrophically affects the hair and skin. 

This is where Tea Tree Oil comes into play as an extremely effective natural remedy. Thanks to its strong antifungal, antibacterial, and anti-inflammatory properties, Tea Tree oil helps in rebalancing the scalp pH, managing excessive sebum production and promote healthy hair growth. So, understanding the science and embracing the benefits of tea tree formulations helps in bringing home the ultimate haircare for the monsoons.
