Tea Tree Oil Benefits for Hair Growth
Scalp Health Improvement
Tea tree oil's antimicrobial and anti-inflammatory properties make it a powerful tool for maintaining a healthy scalp. By keeping the scalp free of infections and inflammation, tea tree oil creates an optimal environment for hair to thrive. This is important because an unhealthy scalp can lead to hair thinning and loss.
Yeast and Dandruff Control

One of the most common scalp issues is dandruff, which is often caused by an overgrowth of yeast.
Tea tree oil’s antifungal properties can help control the growth of yeast on the scalp, particularly Pityrosporum ovale (now known as Malassezia). This reduces dandruff and the itching associated with it. A dandruff-free scalp means fewer chances of hair loss due to constant scratching and irritation.
Oil Regulation on Scalp
Balancing oil production is another way tea tree oil benefits the scalp. Overproduction of oil can lead to greasy hair and clogged hair follicles, which can impede hair growth. Tea tree oil has natural astringent properties that help regulate the scalp's oil production so that hair follicles remain unclogged and healthy.

I started using this twice a day because I noticed my hairline receding. Didn’t pay attention to track results, now my stylist told me my hair has grown a lot since my last root touch up. I'm impressed! - Bailey

Effective Usage of Tea Tree Oil
Mixing with Carrier Oils
Tea tree oil is potent and should never be applied directly to the skin or scalp. Instead, mix it with a carrier oil such as coconut oil, olive oil, or almond oil. These oils each have their unique benefits.
Carrier Oil | Benefits |
---|---|
Coconut Oil | Moisturizing, antifungal properties, penetrates hair shafts. |
Jojoba Oil | Similar to scalp's natural sebum, non-greasy, absorbs easily. |
Olive Oil | Rich in antioxidants, it strengthens hair and adds shine. |
Almond Oil | Lightweight, nourishes hair, and reduces hair breakage. |
When using any tea tree oil mixture, massage it gently onto your scalp. This helps improve blood circulation, further promoting hair growth. Leave it on for at least 30 minutes before washing it out with a gentle shampoo.
Tea Tree Oil in Shampoo
Another effective way to use tea tree oil is by adding a few drops to your regular shampoo. This allows you to incorporate tea tree oil into your hair care routine effortlessly. Make sure to mix the oil thoroughly with the shampoo before applying it to your scalp. Use this mixture consistently to see improvements in your scalp health and hair growth.
Pre-Treatment Application
For those dealing with severe scalp issues, a pre-treatment with tea tree oil can be beneficial. Before washing your hair, apply the diluted tea tree oil mixture directly to problem areas on the scalp. Let it sit for a few minutes to allow the oil to penetrate and work its magic. This pre-treatment can help address specific scalp concerns more directly and effectively.
Scientific Insights on Tea Tree Oil
Research on Hair Growth
While tea tree oil is often praised for its benefits to hair health, its direct impact on hair growth is less documented in scientific literature. However, maintaining a healthy scalp environment is key to promoting hair growth.
A study highlighted that tea tree oil could effectively reduce dandruff, a common scalp issue that can indirectly impact hair growth. This suggests that by creating a healthier scalp environment, tea tree oil may support hair growth indirectly.
Antifungal and Antimicrobial Properties
Tea tree oil is well-known for its antifungal and antimicrobial properties, which helps in maintaining a clean and healthy scalp. The presence of fungi and bacteria on the scalp can lead to conditions such as dandruff and folliculitis, both of which can hinder hair growth.
By applying tea tree oil, you can help eliminate these unwanted microorganisms, thereby preventing infections and promoting a healthier scalp.
Overall Hair Health Benefits
Beyond its ability to improve scalp health, tea tree oil also offers a range of benefits for the hair itself. For example, its cleansing properties help remove buildup from hair products and environmental pollutants. This ensures that hair follicles remain unclogged, allowing hair to grow freely and healthily.
Additionally, tea tree oil can help balance the natural oil production of the scalp. This is particularly beneficial for those with oily scalps, as excessive oil can weigh down hair and make it appear greasy. By regulating oil production, tea tree oil ensures that hair remains light and voluminous.
Potential Risks and Safety Measures
Proper Dilution and Application
Always dilute tea tree oil with a carrier oil such as coconut or jojoba oil. A safe dilution ratio is typically 2–3 drops of tea tree oil per tablespoon of carrier oil. This ensures that the oil is gentle enough for the skin while still retaining its beneficial properties.
Allergic Reactions and Sensitivities

Before using tea tree oil, perform a patch test to check for any allergic reactions.
Apply a small amount of the diluted oil to a small area of skin and wait for 24 hours. If you experience any redness, itching, or irritation, avoid using tea tree oil on your scalp.
Avoiding Internal Use
Tea tree oil is meant for external use only. Ingesting tea tree oil can be toxic and should be strictly avoided. Keep it out of the reach of children and pets to prevent accidental ingestion. If ingested, seek medical attention immediately.
Trybello's Advanced Solution for Tea Tree Oil Enthusiasts
While tea tree oil doesn't directly stimulate hair follicles, its ability to establish a clean, balanced scalp foundation is invaluable in any hair care regimen.
At Trybello, we've created our Hair Helper Spray as a perfect complement to those who appreciate the natural approach of ingredients like tea tree oil. Our innovative formula delivers a precise blend of botanical extracts in a convenient, ready-to-use spray without any measuring, mixing, or diluting—common challenges when working with essential oils.
Each spritz delivers our proprietary "triple-action" growth complex: Castor Oil improves microcirculation, similar to the massaging effect when applying tea tree oil treatments; Biotin strengthens hair structure from within; and Caffeine awakens follicles at the root level.
We've also incorporated Zingiber Officinale (Ginger) Extract and Sophora Flavescens Extract, which provide antimicrobial and anti-inflammatory benefits comparable to tea tree oil but in a perfectly balanced, dermatologist-approved concentration.
Simply apply 4–6 sprays directly to your scalp once daily, gently massage for 30–60 seconds to stimulate circulation, and style as usual. No rinsing required, unlike tea tree oil treatments that can be messy and time-consuming.

Every person’s hair is unique, but we believe in Trybello Hair Helper Spray so much that we back it with a 120-day risk-free trial!
While tea tree oil remains a valuable natural remedy, our Hair Helper Spray represents the evolution of natural hair care: combining traditional botanical wisdom with modern science for superior results without the guesswork.
