Hollow comb tips deliver the serum straight onto the scalp along the part line and temples, where thinning shows, instead of onto the hair. It is a leave-on formula, so caffeine, aminexil and copper tripeptide-1 stay on the scalp all day rather than rinsing away like a shampoo. Panthenol and botanical extracts keep the scalp comfortable, and it dries clean in under a minute.°

Most scalp serums come in a dropper bottle, and most of the serum ends up on the hair. GROW:TURN is a squeeze tube with a comb-tip applicator: hollow tips place the serum on the scalp along the part line and temples, and an ON/OFF twist ring seals it between uses. Inside: caffeine at leave-on strength instead of a rinse-off shampoo, aminexil, copper tripeptide-1, biotin, panthenol and eight botanical extracts.

Because the serum works where you apply it, the first changes are local: a calmer-feeling scalp in the first weeks, then more lift at the roots, and over 2–3 months many notice fine new hairs along the part and temples. It is a daily routine, so give it at least three tubes.°

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.

Remove the cap, turn the ring to ON, press the comb tips against your part line, temples or any area you want to target, and squeeze gently. Massage in for about 30 seconds. Use once daily on a clean, dry scalp; it dries clean, no rinsing needed. Turn the ring to OFF and cap it when done.

For external use only. Avoid contact with eyes. If you use a scalp microneedling stamp, apply the serum the following morning, not directly after stamping.

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 part line 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 part and temples.°

Because the serum is targeted, the first short, wispy hairs tend to show up exactly along the part line 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 part 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 part 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.

Copper Tripeptide-1

GHK-Cu · Conditions the Root Zone

A copper complex skincare brands use on the face, here placed right where hair starts. The comb tips put it on the scalp at the part line, not on the lengths, to support the skin around each 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 part line, 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 part 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 color 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 sulfates.
