What it is
A leave-in serum for the scalp, not the lengths. It is formulated to absorb quickly and leave no film, so it sits under styling rather than replacing it.
It is not a treatment for hair loss. It is a daily scalp serum with three actives at stated percentages — saw palmetto, rosemary and caffeine — plus niacinamide and hyaluronic acid.
How to use
Apply two to three droppers to dry or damp scalp along the parting and hairline. Massage in with the fingertips and leave on. Use once daily.
If your scalp is irritated or broken, wait until it has settled before starting.

What people notice
“The dropper is the good kind — one squeeze, one line along the part. I do it while the kettle boils.”

“No scent, which is what I wanted. Two months in and the bottle is still going, so the price works out.”

How often should I use it?
Once a day. Two to three droppers along the parting and hairline is enough for the whole scalp. Use it on dry or damp hair — it makes no difference to how it absorbs.
Will it make my hair look greasy?
It is a water-light serum, not an oil. Apply it to the scalp rather than the lengths, and give it a minute before you style. Most people find it disappears entirely.
How long does one bottle last?
About eight weeks at once a day, which is why the two-bottle option exists. The serum is stable for 24 months unopened and 12 months after opening.
Can I use it alongside other products?
Yes. Apply it first, on the scalp, then use your usual styling products. If you use a medicated scalp treatment, alternate mornings rather than layering them.
Is it suitable for colour-treated or relaxed hair?
The formula is fragrance-free and free of drying alcohols, so it is designed to sit comfortably on colour-treated and chemically relaxed hair. If your scalp is currently irritated or broken, wait until it has settled.
