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.

How to use

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.
