01
It gets blood moving
Massaging the oil in brings circulation to your scalp, which is how follicles get oxygen and nutrients.
Rosemary Hair Oil · 4 oz
Slow-infused with fresh organic rosemary and a blend of plant oils. No harsh chemicals, no artificial additives. Massage it into your scalp a few times a week.
Why rosemary
We're not going to promise you a miracle.
Here's what we can tell you. Rosemary has been used on hair for a very long time, there's some early research behind it, and a regular scalp massage is good for your hair either way. This oil makes that routine easy to stick with.
02
There's some real research
Small studies suggest rosemary oil may help with thinning when it's used steadily for months. Promising, not proven.
03
Your scalp gets looked after
Jojoba, hemp seed and shea keep it from drying out. Peppermint and tea tree leave it feeling clean.
Made for you if
You've noticed thinning or a hairline that's creeping back.
You want to give your natural growth some support.
Your scalp is dry and your hair has lost some life.
What's inside
Everything in the bottle is on the label.
Plant oils, botanical extracts and vitamin E. That's the full story. Here are four doing most of the work.
Rosemary
The reason you're here. Slow-infused so more of the plant ends up in the oil.
Saw palmetto
A botanical extract that shows up in a lot of thinning-hair routines.
Jojoba & hemp seed
Light oils that moisturize without sitting heavy on your scalp.
Peppermint & tea tree
That cool, clean tingle when you massage it in.

How to use it
Five minutes, a few times a week.
Two or three times a week works best. Consistency matters more than quantity.
- 1
Drop
Put 3 to 5 drops on your fingertips. A little goes further than you'd think.
- 2
Massage
Work it into your scalp, then run what's left through your lengths and ends.
- 3
Leave or wash
For a deeper treatment, leave it on 30 minutes before washing. Or use a drop or two on damp or dry hair day to day.
What to expect
Hair is slow. Plan on months, not days.
Everyone's hair is different and we can't promise yours will respond. This is roughly how it tends to go.
Weeks 1–4
Softer hair and a scalp that feels less dry. This is the part most people notice first.
Months 2–3
Keep going. Hair only grows about half an inch a month, so there isn't much to see yet.
Months 3–6
If rosemary is going to make a difference for you, this is usually when it shows.
I've tried so many products before, but nothing worked like this.

How long until I see a difference?
Softness and a calmer scalp usually come first, within a few weeks. Thickness takes longer. Give it three to six months of regular use before you decide whether it's working for you.
How often should I use it?
Two to three times a week. Use 3 to 5 drops, massage into your scalp, and either leave it in or wash it out after 30 minutes.
Will it leave my hair greasy?
It's an oil, so too much will. Stick to a few drops. If your hair is fine or gets oily fast, use it as a pre-wash treatment and shampoo it out.
Is it OK for sensitive skin?
The formula has essential oils like peppermint and tea tree, plus coconut and other seed oils. Try a drop on your inner arm first, and check the full ingredient list if you have allergies.
What if it doesn't work for me?
