When hair starts to thin or lose strength, the answer lies at the root. The Booster Serum – Strength & Volume delivers a concentrated hit of caffeine and peptides that reactivates follicles, extends the growth phase, and improves hair density from the scalp up.

Powered by Capixyl™, a biomimetic peptide complex and plant-based alternative to Minoxidil, it helps reduce shedding and fortify follicle anchorage for long-term resilience. Yerba Maté caffeine, White Cypress, and Ginkgo Biloba energise the scalp and support healthy circulation, while antioxidant Kaempferol protects follicles from oxidative stress.

Lightweight and fast-absorbing, it leaves no residue — just stronger, thicker-feeling hair with visible lift and vitality. Clinically proven to improve density and strength in as little as five weeks, this serum takes Growth Bomb’s scalp-first philosophy to its highest potency.

Water (Aqua), Butylene Glycol, Propanediol, Glycerin, 1,2-Hexanediol, Hydroxyacetophenone, Xanthan Gum, Ilex Paraguariensis Leaf Extract, Backhousia Anisata Leaf Extract, Callitris Glaucophylla Leaf Extract, Citric Acid, Sodium Benzoate, Dextran, Acetyl Tetrapeptide-3, Potassium Sorbate, Trifolium Pratense (Clover) Flower Extract.

Apply 2–3 drops to targeted scalp areas (part line, temples, crown). Massage in—don’t rinse. Use once or twice daily.

For best results, pair with Supercharge Shampoo/Conditioner to keep the scalp clear and receptive.

    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.
