    A Miracle in a Dropper Bottle for Fine, Oily Hair

    I have fine hair and an oily scalp, and NOTHING has worked for me like this serum. First use and my hair was softer, shinier, less greasy, and somehow had MORE volume at the roots instead of less. It genuinely feels like skincare for the scalp, not just another hair product.

    What shocked me most is that it’s literally replacing dry shampoo for me, which I NEVER expected. My roots stay fresher, lighter, and more balanced without feeling coated or heavy. This serum is a miracle in a dropper bottle.

    I’m never stopping this product. Please NEVER discontinue it.

    Also… why is nobody talking about this???

    It is a great product for your hair. It has no side affects, it smells really nice and I can already feel it working.

    Genuinely impressed with the new hair growth!

    This patch on my scalp used to be super sparse and thinning, and now it’s so full. My hair also feels so much softer and healthier. I got my mum to try it too for her thinning hair, and she loves it. So worth it!

    More volume…

    I have been using this serum daily since I received it, placing one pipette worth of drops at random spots over my scalp. I massage in for two minutes with my fingertips mainly, sometimes with the scalp brush. After just three weeks, my hair is looking and feeling much more voluminous. I’m very very happy with these results.

What is the Peptide Booster Serum?

It's our most concentrated targeted serum. It's a leave-in treatment you apply exactly where you need it. Capixyl™ Peptide supports the look of fuller, denser hair. Concentrated, targeted, leave it in.

How do I use it?

Apply a full pipette to areas of concern on your scalp. Massage in with your fingertips or the Growth Bomb Silicone Scalp Brush. No rinsing needed. For best results, use it daily.

Who is it for?

All hair types. The precision pipette puts you in control. Drop it along your part and hairline, or wherever your hair looks less full. It's a daily step for anyone building a scalp routine.

What's in it?

Capixyl™ (Acetyl Tetrapeptide-3 and Red Clover) supports the look of fuller, denser hair. Yerba Maté Extract charges up the scalp environment. White Cypress and native Australian Aniseed Myrtle support scalp comfort and the appearance of stronger, thicker strands. It's a targeted hit of actives.

Can I use it with the Scalp Brush or Derma Roller?

Yes to the Silicone Scalp Brush. Use it to massage the serum in. The Derma Roller is made to be used before your topical treatments, 1-2 times per week. Always roll first, then apply. Check the Derma Roller page for the full routine.

How long until I can expect to see results?

Everyone's hair is different, so results vary. We ran a 5-week consumer study with 47 participants using Peptide Booster Serum. 98% of participants said they noticed a positive benefit. 96% said their scalp felt more nourished and healthier, and 93% said their hair felt healthier overall. 84% said their hair felt stronger.
