Care From the Outside In
What It Does Where You Apply It
It works right at the scalp, on the exact spots the comb tip touches. Here is what daily use looks like, week by week.
Day 1 “The First Press”
Straight onto the scalp, not the hair.
Turn the ring to ON and press the comb tips along your parting and temples. A gentle squeeze puts the serum exactly where thinning shows, with a light cooling tingle from menthol and eucalyptus.
Weeks 1–2 “A Calmer Scalp”
Less tightness, less itch.°
Thirty seconds of fingertip massage becomes a daily habit. Panthenol and the botanical extracts leave the scalp feeling fresh and comfortable, and the water-light formula dries clean with nothing to rinse.
Weeks 3–6 “Stronger at the Root”
More lift where the hair starts.°
Aminexil helps keep the skin around each root supple, and caffeine stays on the scalp instead of rinsing away. Many notice more body at the roots when they style and hair that feels better anchored.
Months 2–3 “Right Where You Applied It”
Fine new hairs at the parting and temples.°
Because the serum is targeted, the first short, wispy hairs tend to show up exactly along the parting and temples, the spots the comb tip reaches every morning.
Months 3+ “Longer, Stronger, Fuller”
Hair that grows in fuller and stronger.°
The fine new hairs at the parting and temples keep growing in and filling out. Lengths feel stronger with less breakage when you brush, ends look healthier, and hair holds more volume from root to tip. The parting looks narrower under bright light. One tube lasts about a month; keep it daily to keep the results.
What's Inside
Four Actives, Delivered to the Root.
Biotin, Panthenol & Botanicals
Vitamin B7 · Pro-vitamin B5 · 8 extracts
Biotin and panthenol condition the scalp and hair, while camellia, plum blossom, peach blossom and houttuynia extracts bring the soothing, lightly cooling finish of a Korean scalp ampoule.
Caffeine
Leave-on · Not rinsed off
The same idea as a caffeine shampoo, done properly: at serum strength and left on the scalp instead of rinsed away after thirty seconds.
Aminexil
Diaminopyrimidine Oxide
A scalp-conditioning active with a long history in dermocosmetic hair serums, included to help keep the scalp around the root supple and comfortable.°
Plus camellia, plum blossom, peach blossom, houttuynia, hollyhock, viola and sunflower flower extracts with saccharomyces and lactobacillus ferments.

Before You Ask
Questions? We Have Answers.
How do I use the serum?
Once a day on a clean, dry scalp. Turn the ring to ON, press the comb tips against the parting, temples or crown, squeeze gently and massage in for about 30 seconds. It dries clean; no rinsing. Turn the ring to OFF and cap it when done.
Can I use it with my other hair products?
Yes. Apply it to a dry scalp first and give it under a minute to dry clean, then style as usual. Your regular shampoo, conditioner and styling products are all fine. Just skip washing your hair right after, so the serum can stay on the scalp.
When will I see results?
Because the serum works where you apply it, the first changes are local: a calmer scalp in the first weeks, more lift at the roots, then fine new hairs along the parting and temples over 2–3 months for many people. Individual experiences vary and we do not promise a particular result. If you are concerned about new or persistent hair thinning, speak with a qualified healthcare professional.
Will it make my hair greasy?
No. The formula is water-based and dries clean in under a minute, so you can blow-dry or style right after. The comb applicator places it on the scalp rather than on the hair.
Is it suitable for men and women, and for all hair types?
Yes. It is a scalp product, not a hair product, so hair type, length and colour do not matter. It is used the same way on straight, wavy, curly or coily hair.
Can I use it with a scalp stamp or roller?
Yes, with one rule: stamp in the evening and apply the serum the next morning, not directly after. The formula contains alcohol and menthol, which can sting on freshly needled skin.
What is in it?
Caffeine, diaminopyrimidine oxide (aminexil), copper tripeptide-1, biotin, panthenol and a blend of botanical extracts including camellia, plum blossom, peach blossom and houttuynia. The full ingredient list is printed on the tube and listed on this page. Free of parabens, silicones, mineral oil and sulphates.
