See it in action

    Most serums sit on the strands. Klaré is brushed onto the scalp, and its water light formula reaches the root. 

    The Korean formulated actives run in an order to calm, heal, wake, support and grow your hair follicle. 

    It's the at-home version of the Korean scalp clinics’ 12 step treatments. 

    We can't tell you that, and no ad should. What we can tell you: a follicle that's gone quiet isn't the same as one that's gone. Take a Day 1 photo and give it 12 weeks. You'll know within 30 days whether your scalp is responding, and the first 30 days are guaranteed.

    Part your hair, glide the brush tip along the part, then massage for a few seconds. Twice a day, morning and night. It dries before you've picked an outfit.

    🌿 Heartleaf — calms a reactive scalp

    💧 Plant-Derived Exosomes — precision scalp delivery used in scalp clinics

    ☕ Caffeine — supports circulation at the root

    🌸 Korean Botanical Complex — soothes and nourishes

    ❄️ Menthol + Eucalyptus — cooling you can feel

    Ships in 24 hrs. 5-8 Business Days Delivery. 30-day money-back guarantee. 

    In Seoul, this is a clinic appointment.

    Exosome scalp therapy there can involve microneedling, 3–5 sessions, and $600+ per visit. Klaré delivers Korean blend of plant-derived exosomes and actives directly to your scalp with a built-in brush, at home.

     Made For The Scalp, Not Just Hair 

    Klaré is a water-light serum with a built-in brush tip. You press it right onto the scalp, where thinning actually starts. Caffeine and heartleaf go straight to the root, while Nano Exosome Technology helps deliver the actives more effectively into the scalp as the brush massages it in. No rinse. No grease. About 30 seconds, twice a day.

    3 Simple Steps Towards Fuller-looking Hair

    • 1.Twist

      Twist the brush head to unlock. You’re ready to go.

    • 2. Press

      Press the serum directly onto your scalp—hairline, part, crown, or temples.

    • 3.Brush

      Gently brush it into your scalp. No rinsing needed. Use morning and night.

       What's Inside The Serum? 

      Five clinically-studied actives doing different jobs

      • Heartleaf (Houttuynia cordata)

        A stressed, inflamed follicle cycles out early. Heartleaf, long used in Korean scalp care for irritation, settles the scalp first so the root can respond.

      • Plant-Derived Exosomes

        Exosomes are used in Korean scalp clinics, as tiny messengers that carry a "wake up" signal to a resting follicle. Same approach in a water light formula to reach the root without needle.

      • Caffiene

        Clinically studied caffeine supports circulation right at the root.  So the scalp stays active rather than dormant.

      • Korean Botanical Complex

        A blend led by Camellia, plum & peach blossom, hollyhock and sunflower extracts that conditions the scalp so the follicle can hold its phase instead of shedding early.

      • Menthol + Eucalyptus

        The effect you notice on the first use: a clean, cooling sensation- proof it reached the scalp, not the strands.

        Common Questions We Hear From Our Customers

        Fair question — most of what you've tried was a hair product. Oils, masks, thickening shampoos: they all sit on the lengths, and the lengths are already dead tissue. This is a water-thin serum with a comb built into the cap, so it goes onto the part line where the follicle actually is. Different place, not just a different bottle.

        Hair grows on a cycle you can't rush — roughly [1cm] a month. Most women notice the scalp changing first: less itch, less tightness, usually inside [2–3] weeks. Visible baby hairs at the hairline take longer, typically month [2–3]. Anyone promising a difference in 7 days is selling you a photo angle.

        Then you send it back. [60] days, opened tube, no questions. We'd rather refund you than have you leave a review saying it did nothing — that costs us more than the bottle does.

        No — it's water-light, not an oil. It absorbs in under a minute and there's nothing to rinse out. You can do your scalp in the morning and leave the house with clean hair.

        Yes. It goes on the scalp, not the strands, so it won't strip color or interfere with a relaxer. Best on a clean, dry scalp — before you style, not after.

        No. This isn't minoxidil, so there's no shedding rebound when you quit. Your scalp just goes back to whatever it was doing before. That said, it's supporting an ongoing cycle, so results hold as long as you keep going.

        Same scalp, same follicles, same product. We built the brand around women because that's who was being ignored, but nothing in the formula is sex-specific.

        Four actives in sequence: heartleaf-derived exosome water to signal, heartleaf to calm, caffeine to support circulation at the root, and a Korean botanical complex for antioxidant cover. No minoxidil, no fragrance, no silicones. Full INCI is on the tube and on this page — read it, we'd rather you did.

        Twist the cap to unlock. Part your hair, press the brush to your scalp, squeeze gently, and comb it through the part. Move to the next section. About sixty seconds, once a day, on a dry scalp. No rinsing.

        • "My hair had been shedding so much in menopause and wash days were worse. 
          After using this daily, I’m seeing way less shedding and my ugly crown patch is filling in. It doesn’t leave my scalp oily either so love it <3"

           Monique D. 

        • "I usually hate scalp serums because they make my curls feel greasy, but this one doesn’t. Its super light plus my scalp feels so calm. I also noticed less breakage and now my curls feel more fuller than before."
