Dropper serums run down the lengths
Most scalp serums come in dropper bottles. The liquid slides off the hair before it reaches the skin, so the roots feel greasy and the scalp itself stays untreated.
- Comb tip parts the hair and puts the gel on the scalp, not the strands
- Water-based formula — Aqua, Glycerin and Dipropylene Glycol lead the list, with no oils or butters
- Squeeze the tube where you want it instead of counting pipette drops over your head
What it does, and how
Five things that make a daily scalp step quick enough to actually do.
Built-in comb tip
Short, blunt bristles part the hair as you glide, so the serum lands on the scalp instead of coating the lengths.
Water-based texture
The ingredient list opens with Aqua, Glycerin and Dipropylene Glycol. No oils or butters are listed, so fine hair isn't weighed down at the root.
Heartleaf formula
The tube is labeled (V)BioExo-Water (Heartleaf). Heartleaf extract is a soothing botanical widely used in Korean scalp and skin care.
Cooling menthol finish
Menthol is in the formula and leaves a fresh, cool feel on the scalp as you comb the serum through.
3.38 fl oz squeeze tube
A full-size 100 mL tube you squeeze rather than pipette, so you control how much comes out along each part line.
What it doesn't do
This is a cosmetic, not a drug. It contains no minoxidil or other active pharmaceutical ingredient, doesn't treat hair loss or any scalp condition, and doesn't clean, color or change the texture of your hair. For a medical scalp issue, see a doctor.
One step after you towel off
Where the tube actually gets used in a normal week.
Who this serum is for
Great for
- You want a scalp step, not another oil on your lengths
- Your roots get oily fast and heavy serums make it worse
- You find dropper bottles messy and hard to aim
- You'll use a leave-on product after towel-drying
Not the right pick if
- You're after regrowth results — this is a cosmetic
- You want minoxidil or another medicated treatment
- Your scalp is broken, irritated or sunburned right now
A comb tip that parts the hair
The applicator head snaps onto the base of the tube, so the serum comes out between the bristles and goes straight onto the skin.
- About 18–24 short, blunt, straight bristles in rows, the same width as the tube
- Two release tabs on the collar let you pull the head off to rinse it
- The tube stands on the comb head, so it's ready to use upside down

Tips for a clean first use
Three things that make the first few applications go smoothly.
Part the hair first
Make a clear part on dry or damp hair so you can see the scalp before the comb tip touches it.
Squeeze less than you think
A short squeeze covers one part line. Work section by section instead of emptying a lot into one spot.
Expect a cool tingle
Menthol leaves a cooling feel. If your scalp stings or turns red, stop using it and check with a doctor.

What people ask most
Will it work with my hair type or length?
The comb tip is built to part hair and reach the scalp, so it suits most lengths and textures. We don't claim tested performance on specific hair types — it's a scalp-care step, not a styling product.
How much do I use, and how often?
Press the comb tip to the scalp and squeeze gently along each part line, then massage in with your fingertips. Leave it on, no rinsing. Follow the product label for frequency and full instructions.
Is it safe to use?
It's for external use on the scalp only. Don't use it on broken, irritated or sunburned skin, and stop if irritation occurs. It contains menthol, which gives a cooling feel. Not for internal use.
Does it contain minoxidil or regrow hair?
No. There's no minoxidil, finasteride or any other active pharmaceutical ingredient in the formula. It's a cosmetic scalp serum and makes no regrowth, shedding or timeline claims. For hair loss, speak with a doctor.
How do I clean the comb tip?
Rinse the tip under warm water and wipe it dry if product builds up between the bristles. Store the tube upright, away from direct sunlight and heat, and don't share the applicator.
