Scalp Serum with Built-In Brush Head — Heartleaf Exosome Scalp Treatment for Fuller-Looking Hair, 3.38 fl oz (100 ml)

Scalp care fails on delivery, not on formula. This one solves the delivery.

A dropper puts serum on your hair. A roller drags it around. This bottle has 38 precision bristles built into the cap, so the serum goes through the hair and lands on the scalp, where it was always meant to be — and you massage it in with the same motion.

The experience

Tip, part, glide. The bristles separate hair as they move so the liquid reaches skin rather than pooling on the lengths, and the massage happens as a by-product of applying it. The serum itself is light and fast-absorbing with no greasy residue, so roots don't look like you skipped a wash. Lightly scented with a plant-derived aroma rather than added fragrance.

What's inside

• Heartleaf-derived exosome complex — the brand's Hair Revitalize Complex, for scalp comfort and condition
• Scalp-Clera — the soothing base of the formula
• Cistus flower and white edelweiss extracts — calming botanicals aimed at dry, itchy scalps
• No artificial fragrance — a light plant aroma instead, which matters on a sensitive scalp

How to use it

Once a day, on wet or dry hair. Part the hair, hold the bottle upright against the scalp and squeeze gently as you glide the brush along the parting. Work in sections — front hairline, crown, temples, then the back — rather than emptying it into one place. Massage for thirty seconds or so with the bristles, and don't rinse. Rinse the brush head itself under the tap every so often.

What it is, and what it isn't

A cosmetic scalp serum for scalp condition, comfort and the look of fuller hair. It is not a medicine and not a hair-loss treatment. Products that make genuine hair-growth claims are regulated as drugs, and this isn't one — you'll see this category advertised with clinical-sounding language and user numbers, and we've left all of that off the page. If shedding is your concern, a dermatologist is the right first step.

Before you start

Patch test behind the ear before first use. Not for use on a broken, sunburnt, freshly bleached or inflamed scalp, and not alongside strong exfoliants or medicated scalp products without checking with your pharmacist first. Avoid contact with eyes — rinse with clean water if it happens. Stop if you get persistent itching or redness. External scalp use only.

Questions people ask

What are exosomes?
Extremely small vesicles that cells use to carry signals. In cosmetics they're used as a conditioning ingredient — here, derived from heartleaf.

Will it make my hair grow?
We won't claim that. It's formulated for scalp comfort and condition, and for hair that looks fuller. Anything advertising guaranteed regrowth is making a drug claim.

Wet hair or dry hair?
Either works. Towel-dried is the easiest for parting into sections.

Will it make my roots greasy?
No — it's a light formula that absorbs quickly. Greasiness almost always comes from applying it to the lengths instead of the scalp.

Do I rinse it out?
No. Leave it in.

How long does the bottle last?
At once daily, around two months.

Is it safe with colour-treated hair?
Yes, once the scalp has settled after colouring. Wait a few days after bleaching.

Can I use it with the Red Light Therapy Cap?
Yes — apply the serum, let it absorb, then wear the cap.
