What Is Tea Tree Shampoo?

Tea tree shampoo is any cleansing shampoo formula that contains scalp-purifying tea tree oil (Melaleuca alternifolia).

Tea tree shampoos became popular across the globe in the 90s thanks to the cool, tingling sensation and signature clean scent this natural essential oil is known for. Tea tree shampoos turn regular cleansing into an entire experience that pleases the senses.

But the benefits reach far beyond the cool, tingly feeling and deliciously natural scent tea tree shampoos leave behind! Let’s take a look at what tea tree oil actually does for a shampoo and how it works.

Tea Tree Shampoo: What It Does

Tea tree oil is an essential oil distilled from the leaves of the tea tree plant (Melaleuca alternifolia) that is native to Australia. When it’s added to a shampoo formula, it acts as a soothing, purifying, and detoxifying agent. 

Tea tree shampoo can refresh the hair and scalp, cleanse away oil, dirt, bacteria, and fungus, and gives the scalp an addictive, tingly sensation when you use it.

It’s also known for its potent scent – described as similar to eucalyptus and camphor, the main ingredient in Vicks VapoRub. For centuries, native Aborigine tribes have been using this potent plant and its oils as an antiseptic and wound treatment.

But modern scientific discoveries about this miraculous plant and essential oil have made tea tree oil a staple in purifying and cleansing hair, body, and beauty products – especially shampoo.   

Tea Tree Shampoo: How It Works

Tea tree oil works in shampoos, conditioners, masks, and similar hair care products through antibacterial, antimicrobial, and antifungal action.

It kills and inhibits the growth of bacteria, fungus, and other microbes that lead to infection, itchiness, flakes, and irritation. Tea tree oil is effective in soothing and purifying/detoxifying shampoos because it minimizes scalp irritation and removes product buildup with ease.

When you feel your scalp needs a deep cleanse that won’t leave it dry and stripped of all natural oils, reach for a good tea tree shampoo. 

The unique thing about tea tree shampoos is that high-quality options work both during use (thanks to the tingly, soothing sensation it creates on the scalp when you lather) and continue soothing and preventing microbial irritation after use for longer-lasting results. 

Scientist Arthur Penfold first found out about the antibacterial, antimicrobial, and antifungal properties of the tea tree plant (and tea tree oil) back in 1922.

He knew that Aborigine tribes used the plant and its essential oils to treat infections and clean wounds, but wasn’t sure why it was effective. Penfold studied the tea tree plant for years and discovered what the tribespeople had known for centuries.

His studies led him to conclude that tea tree oil is 13 times stronger than phenol – carbolic acid, the main antiseptic and disinfectant used at the time. No wonder this has become a staple ingredient in detoxifying, purifying, anti-dandruff, and soothing shampoos!

Benefits of Using Tea Tree Shampoo

Tea tree shampoo is good for more than just leaving your scalp feeling tingly and refreshed. Here’s a list of the main benefits users get from using a good quality tea tree shampoo. Could any of these benefits help solve your current hair care woes?

Cleanses Away Impurities and Buildup

Tea tree oil as a shampoo ingredient indicates the formula will bust buildup and wash away impurities from the scalp for a refreshed, truly clean feeling. 

If you’ve been a little heavy-handed with the dry shampoo lately or can’t seem to get every trace of a heavy product out, a tea tree shampoo is the solution.

Formulas that contain tea tree oil can also help cleanse away dead skin cells from the scalp and keep your follicles unclogged and free from all types of buildup. 

Soothes and Minimizes Scalp Irritation

Tea tree shampoos can help soothe and minimize scalp irritation. If you’re dealing with redness, soreness, bumps or breakouts on your scalp, or frustrating dandruff, treating the scalp and hair with tea tree essential oil in your shampoo is a great idea.

The tingly feeling instantly calms an angry scalp to leave your hair and follicles feeling clean, soothed, and refreshed. 

Treats and Reduces Dandruff 

Research shows that shampoo containing potent tea tree oil can be used to treat and eliminate dandruff from the scalp. Dandruff is often caused by a specific type of yeast fungus – Malassezia furfur.

And it just so happens that tea tree oil is a powerful antifungal. Regularly using a good tea tree shampoo can help you say bye-bye to flakes, scales, and itchiness from dandruff.  

Enhances Healthy Hair Growth

Using tea tree shampoo can help pave the way for healthier hair growth due to its purifying and buildup-removing properties. It’s also been proven to make hair growth medications and supplements more effective. 

Tea tree oil helps clear away dirt, oil, and dead skin cells that can hamper your follicles’ growth abilities and reduce the rate and quality of your hair growth.

With a cleansed, balanced, and healthy scalp, your body’s natural hair growth process can get back on track with no flakes, irritation, or itching to stand in the way! 

Kills Head Lice and Lice Eggs

Another little-known benefit of tea tree shampoo is that it can actually kill and eliminate head lice in all stages of the life cycle.

If you or your child is dealing with a lice infestation, studies show that using a tea tree shampoo with at least 1% tea tree oil can kill 100% of existing head lice. Using a stronger concentration (at least 2% tea tree oil) can prevent lice eggs from hatching. 

Tea tree oil shampoo is a great thing to have on hand just in case the little buggies show up in a scalp near you, but an even better option is to use tea tree shampoo as a way to prevent a head lice infestation in the first place.

Women who are struggling to grow their hair to new lengths or experiencing hair loss should look at Billy Jealousy Monsoon Mist Energizing Tea Tree Shampoo.

This is the best growth-enhancing tea tree shampoo on our list. It promotes healthy new hair growth and might be just the product to take you over the hump if you’ve been struggling to grow your hair. 

Tea tree and peppermint oils are the key ingredients in this growth-boosting formula. The company says this tag-team duo effectively unclogs scalp pores and follicles to clear out debris and dead skin cells, paving the way for new growth.

The formula stimulates blood flow to your scalp as well, further increasing growth and strengthening hair.

If you’re dealing with the dreaded flakes, this shampoo can correct the problem and reduce dandruff-related thinning. Don’t just believe the company’s claims, though.

The science shows that tea tree oil really is effective for boosting hair growth. One study compared the effects of minoxidil, the main ingredient in Rogaine, alone and when used in combination with tea tree oil.

When tea tree oil was added to the mix, participants had a “significantly superior” hair growth response compared to when they used minoxidil alone.

If your hair seems hopelessly and chronically dry, Melaleuca Original Tea Tree Shampoo is just what your scalp has been begging for. This moisture-rich formula can hydrate and restore even the driest hair to give you lasting moisture that nourishes, protects, and soothes your scalp.

Chronic dryness leads to a litany of hair issues: Frizz, dullness, breakage, tangles, and even hair loss are among the most common dry-hair woes.

If you’re mentally checking off these boxes, the original Melaleuca tea tree formulated shampoo is the answer.

The formula is gentle but potent, eliminating dryness while leaving your scalp’s therapeutic natural oils in place. It introduces moisture deep into strands to leave you with lasting moisture that protects your hair while leaving it glossy, detangled, and soft. 

And if dryness is causing your scalp to flake, this heavily-hydrating shampoo can soften and remove existing flakes while preventing more flakes from forming. 

Customers give it a solid rating of 4.5 stars overall, and the few negative reviews we found indicated the formula was a little heavy for fine or thin hair.

As long as you use a small amount or have very dry, coarse hair, you shouldn’t have any problems with this intensely moisturizing tea tree-spiked shampoo.

Things to Consider

Tea tree shampoo is a no-brainer for most – it has the power to cleanse, purify, and refresh your scalp to leave your hair clean, bouncy, and soft with a refreshing scent. But before you start lathering up with a tea tree-infused shampoo, there are a few important things to know about:

  • Use tea tree shampoo, not pure tea tree oil. If you’re of the “more is better” mindset, you might think skipping tea tree shampoo in favor of the more-potent pure tea tree oil is a good idea. But pure tea tree oil is harsh and irritating when used directly on the scalp. It can lead to redness, stinging, irritation, and itching. Stick to tea tree-infused shampoo instead, which can contain up to 5% of this potent oil and won’t cause irritation. 
  • Use your tea tree shampoo 2-3 times per week. Shampooing daily with potent tea tree oil in the mix isn’t a great idea because prolonged contact with your scalp can lead to irritation – the opposite of the soothing, refreshing effects you want! Shampoo 2-3 times a week with your tea tree formula and use a gentle, sulfate-free shampoo in between if you need to wash your hair daily. 
  • Check with your doctor before using. If you have a history of allergies, it’s wise to check with your doctor or allergist before you start using tea tree shampoo. A small percentage of people are allergic to compounds in tea tree oil, and your doctor can explain how to patch test a new product to avoid a potentially bad allergic reaction. 
  • Preteen boys shouldn’t use tea tree + lavender shampoo. Research is still early, but studies indicate that young boys shouldn’t use products containing tea tree in combination with lavender oil due to the effect they have on male sex hormones. One study found that pre-pubescent boys were more likely to develop breast tissue when they used this combination of essential oils. So keep this one for yourself and don’t share it with your preteen son!
