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.

Ingredients

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.

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.

RESULTS AFTER 3 MONTHS

I thought most hair growth products are kinda a scam.. but I'm pleasantly surprised. I naturally have pretty thin hair and my scalp is a bit sparse, so happy I switched to this shampoo and conditioner and started using the booster serum every night. Never thought my hair would actually grow thicker and healthier but here we are!

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!
