      The Technology

      Powered by Vegan PDRN

      Vegan PDRN is one of Korean skincare's most talked-about ingredients, known for supporting skin renewal. Paired with caffeine and applied directly to the root via the built-in brush, it works at the scalp — not just the surface — to help support the look of fuller, healthier-looking hair.

      The Applicator

      Built to Reach the Root

      The built-in massage brush parts hair and delivers serum straight to the scalp, so every drop reaches skin instead of getting caught in strands. Glide, don't guess.

       
       

      FAQs

      check_box

      Will this work on all hair types?

      Yes. The lightweight, fast-absorbing formula is designed to work across hair types and textures without weighing hair down or leaving residue.

      check_box

      How often should I use it, and when will I see results?

      Use daily for best results. Most people notice an instantly cooler, more refreshed scalp from the first use, less visible buildup within 2–4 weeks, and fuller-looking hair with consistent use over 4–8 weeks.

      check_box

      Is it suitable for everyday use as well as sensitive scalps?

      Yes, it's formulated for daily use and designed to feel gentle and cooling on the scalp. As with any new scalp product, we recommend a patch test first if you have a history of sensitivity.

      check_box

      How do I use the built-in brush applicator?

      Part your hair into sections and glide the brush directly along the scalp, hairline, and roots. The bristles help massage the serum in while gently exfoliating buildup as you go.

        Obsessed

        I use the brush serum first and then the ampoule on the thinner spots. Been almost 2 months now and I honestly see a difference. Hair feels thicker and I notice much less shedding in the shower.

        It works!

        I almost didnt buy it because I thought it was another hyped product. Glad I did. My scalp feels refreshed after every use and I've started seeing little baby hairs near my forehead. Worth every penny.
