TWO WAYS TO USE ROSEMARY
Oil or serum?
There’s room for either, or both.
Original Rosemary Oil is a pre-wash treatment: massage it in, leave it to work, then wash out. Rosemary Scalp Serum is a lightweight leave-in treatment for use between oil-treatment days, or on its own.
| Your routine | Original Rosemary Oil | Rosemary Scalp Serum |
|---|---|---|
| The format | Botanical oil blend | Lightweight, water-based serum |
| When to use | Before washing your hair | Daily on its own, or between oil-treatment days |
| After applying | Massage in, leave to work, then wash out | Massage in and leave in |

Will this serum help me?
We often get asked whether our Rosemary based products will help with certain conditions, so here are some of the common conditions they can help with:
- Androgenetic alopecia (male and female pattern baldness)
- Telogen effluvium (stress-related hair loss)
- Hormone related hair loss (pregnancy, post-partum, menopause, thyroid)
- Medication related hair loss (eg. chemotherapy)
- Autoimmune related hair loss (eg. alopecia areata)
- Traction alopecia (from tight hairstyles)
- Scalp infections (eg ringworm)
- Polycystic ovary syndrome (PCOS)
Is the serum an oil?
No. Our Rosemary Scalp Serum is a lightweight, water-based, leave-in treatment. It contains rosemary ingredients, including rosemary oil, alongside caffeine, niacinamide and peptides.
Its formula and use are different from our Original Rosemary Oil, which is an oil-based pre-wash treatment that you wash out.
How often should I use it, and do I wash it out?
Use the serum once a day. Apply 1–2 pipettes directly to your scalp, parting your hair to reach the skin, and gently massage in for up to five minutes.
Leave it in. There’s no need to rinse or wash your hair afterwards. If you also use our Original Rosemary Oil, use the serum between your oil-treatment days.
Do I need to use the oil as well?
No. The serum can be used on its own as your daily leave-in scalp treatment.
If you already use our Original Rosemary Oil, you can keep it as your pre-wash treatment and add the serum between oil-treatment days. This lets you keep your oil routine while adding a lightweight leave-in step without extra hair washes.
If you’d like both products, The Rosemary Duo includes a 60ml bottle of each.
How soon will I see a difference?
Changes in the look and feel of your hair take time, and results vary from person to person. We encourage you to make the serum part of a consistent routine and give it several months rather than judging it after a few applications.
Think of it as a long-term commitment to caring for your scalp and hair. There isn’t one guaranteed timeline for everyone, and you shouldn’t expect a transformation within a few days.
Our six-month results promise gives you time to assess your routine, subject to the guarantee conditions.
Which size should I choose?
We generally recommend the 60ml bottle. It offers better value per ml and is estimated to last around two months, helping you keep your routine going without needing to reorder as soon.
The 30ml bottle is an option if you prefer to start with a smaller size. Both contain the same formula.
How long will a bottle last?
As a general guide, a 30ml bottle is estimated to last around one month and a 60ml bottle around two months. This will depend on how often you use the serum and how much you apply.
If you use the serum between oil-treatment days rather than every day, your bottle may last longer.
Do you offer a guarantee?
Yes. If it’s not for you within the first 30 days, we’ll refund you in full, even if you’ve opened and used the product.
Our six-month results promise also covers the serum: if you use it consistently for six months and don’t see a visible difference in how your hair looks and feels, you can request a refund. Your order history must show enough product for consistent use, and claims must be made within 30 days after the six-month period. See our full guarantee details.
