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???

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!

key active ingredients

We blend proven botanicals with clever science to wake up your scalp, energise your roots, and get your hair back to its bold, bouncy best.

Capixyl™

A patented biomimetic peptide combined with red clover flower extract that is rich in biochanin A. It’s an innovative and powerful cosmetic ingredient providing fuller, thicker and healthier looking hair.

Biotin

Biotin plays a key role in supporting healthy hair. A deficiency can lead to thinning strands and a lacklustre look, so keeping your levels topped up is essential if you’re chasing stronger, healthier-feeling hair.

Yerba Mate

Antioxidant-rich Yerba Maté extract is packed with caffeine energy. This helps protect hair from oxidative damage and supports healthy roots for optimal condition and strength.
