More Info

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.

Amazing product
I decided to use Growth Bomb as it gets a good rap from my product app, Yuca. Yuca tells me if there are any nasty chemicals in food and cosmetics. There are none in Growth Bomb. My hair feels thicker, heavier and looks fuller. Thank you for keeping it healthy and functional.
