Short answer: For hair, most people should buy a ready-to-use tea tree hair oil, not a bottle of pure essential oil. Our pick is Plant of Life Tea Tree Hair Oil: $19.99 for 120 mL ($0.17 per mL), tea tree and peppermint in a light MCT and jojoba base, with the USDA Organic seal on the label.
Prefer to mix your own? Buy a pure tea tree essential oil and dilute it. Our organic 120 mL bottle is $0.27 per mL. Handcraft Blends is the lowest in our table at $0.17 per mL on Amazon.ca.

How we compared
We compared label facts and prices: what type of product it is, size, CAD price, price per mL, organic claims, the bottle, and where Canadians can buy it. Prices were checked October 28, 2026 on each brand's own site, Amazon.ca and Well.ca. Where a listing does not state something, we say "not listed". Prices move often, so check before you buy.
Hair oil or essential oil? Decide this first
Pure tea tree essential oil is concentrated oil steam distilled from the leaves of Melaleuca alternifolia. It is not meant to go on your scalp straight from the bottle. Our own essential oil page tells you to dilute it with a carrier oil before any use outside aromatherapy. It suits people who like to mix their own blend or add a little to shampoo.
A ready-to-use tea tree hair oil already has the tea tree diluted in carrier oils. You section your hair, apply to the scalp, massage and you are done. It suits anyone who wants a scalp routine with no measuring.
So price per mL is not apples to apples. A cheap essential oil still needs a carrier oil before you can use it. A blend is the finished product.

Best overall: Plant of Life Tea Tree Hair Oil
This is the one to buy if you want tea tree in your scalp routine without mixing anything. Tea tree brings the clean, fresh feel. Peppermint adds a cool tingle. MCT and jojoba keep it light, so it does not weigh hair down. Five ingredients, all listed on the product page.
Two ways to use it. As a scalp treatment: section your hair, apply a small amount to the scalp, massage, then leave it in or rinse after 15 to 30 minutes. As a pre-wash: apply through scalp and roots, sit 10 to 15 minutes under a shower cap, then shampoo. Use it 2 to 3 times a week. On a sensitive scalp, start with shorter contact time.
Best budget blend: Majestic Pure Tea Tree Oil for Hair
Straight talk: per mL, this is the cheapest ready-to-use blend we found, at $17.99 for 198 mL on Amazon.ca ($0.09 per mL). It mixes tea tree with argan, jojoba and grapeseed oils. If the biggest bottle for the least money is your goal, buy it.
Why people still pick ours: the Majestic Pure listing does not show a full ingredient list or an organic claim. Ours lists all five ingredients, carries the USDA Organic seal, and adds peppermint for that cooling feel.
Best organic essential oil for DIY: Plant of Life Tea Tree Essential Oil
If you like to build your own blend, this is 100% organic tea tree oil (Melaleuca alternifolia), steam distilled, in three sizes. The 120 mL bottle works out to $0.27 per mL. It is rated 4.89 out of 5 from 19 reviews on our store. Pair a small amount with your shampoo, or dilute it in a carrier oil such as jojoba before it touches your scalp.
Best budget essential oil: Handcraft Blends
At $19.99 for 118 mL on Amazon.ca ($0.17 per mL), Handcraft Blends is the cheapest pure tea tree oil per mL in our table. It comes in amber glass with a glass dropper. The listing makes no organic claim, so if organic matters, our 120 mL bottle costs $0.10 more per mL.
Best known pharmacy name: Thursday Plantation
Thursday Plantation is the big name here, with 2,096 ratings on Amazon.ca. Well.ca lists it as sourced and made in Australia, with a minimum of 40% terpinen-4-ol. It is $11.19 for 25 mL on Amazon.ca and $29.99 for 100 mL on Well.ca. Its own directions focus on minor cuts, pimples, bites and stings, so for hair you still need to dilute it yourself.
Paul Mitchell: a styling oil, not a scalp oil
Paul Mitchell Tea Tree Lavender Mint Nourishing Oil is sold as an oil, but it is built for lengths. Its ingredient list starts with caprylic/capric triglyceride, C12-15 alkyl benzoate and isododecane, and includes fragrance. Paul Mitchell says to apply it to damp or dry hair for smoothing. It is $36.50 for 50 mL on Amazon.ca ($0.73 per mL). Great for frizz, not what you want for a tea tree scalp routine.
Also on the shelf: NOW, Desert Essence and Saje
NOW Tea Tree Oil is steam distilled from leaves, $19.99 for 30 mL on Well.ca. Desert Essence 100% Australian Tea Tree Oil is $13.99 for 15 mL or $33.99 for 60 mL on Well.ca. Saje sells a 10 mL bottle for $28.00, which is easy to pick up in store but works out to $2.80 per mL.
What to look for when buying tea tree oil for hair
- Decide blend or essential oil. A blend is ready to use. An essential oil must be diluted first.
- A light base. MCT, jojoba and grapeseed feel lighter on the scalp than heavy oils.
- A full ingredient list. If the listing will not tell you what is in it, skip it.
- Melaleuca alternifolia on the label. That is true tea tree.
- Price per mL, plus the cost of a carrier oil if you are buying an essential oil.
FAQ
Can I put tea tree oil directly on my scalp?
Not pure tea tree essential oil. It is highly concentrated, so mix a small amount into a carrier oil like jojoba first, or add a little to your shampoo. If you do not want to mix, use a ready-to-use blend such as Plant of Life Tea Tree Hair Oil, which is already diluted. Need a carrier? See our best carrier oils for skin and hair guide.
How do I use tea tree oil for my hair?
The simplest routine is a pre-wash: part your hair, apply a ready-to-use tea tree hair oil to the scalp, massage, wait 10 to 15 minutes, then shampoo. You can also leave a small amount in. People use tea tree in their scalp routine for a clean, fresh, balanced feel, especially when the scalp feels oily or itchy.
How often should I use tea tree oil on my scalp?
Our directions for Tea Tree Hair Oil: 2 to 3 times a week. If your scalp is sensitive, start with shorter contact time and build up. Consistency matters more than using a lot at once.
Can I add tea tree oil to my shampoo?
Yes. Add a small amount of tea tree essential oil to the shampoo in your palm, not the whole bottle, so you control how much you use each wash. It is the easiest way to use a pure essential oil without making a separate blend.
Tea tree or rosemary oil: which is better for hair?
They do different jobs. People reach for tea tree for a clean, fresh-feeling scalp and rosemary for thicker-looking hair. Many use both on different days. If rosemary is on your list too, compare options in our best rosemary oil for hair in Canada guide.
