Product description
- 2025 Men’s Health Grooming Award Winner — Clinically proven exosome scalp serum reduces visible shedding and boosts density in as little as 4 weeks, earning trust as a leading hair regrowth treatment, without side effects, in Dermatologists, women and men.
- Powered by Advanced NX35 Technology — Billions of exosomes for hair deliver caffeine, niacinamide and peptides to the scalp surface, using biomimetic science, creating a lightweight hair growth serum that works without oils or drug actives.
- Clean, Vegan & Sensitive-Safe — Silicone-free, dye-free, paraben-free and cruelty-free; gentle on colour-treated hair and suitable for every texture, making it easy to add to any daily routine.
- Naturally Fuller-Looking Hair — Acts as a non-sticky hair thickening serum, coating fibres for instant, soft volume while supporting long-term strength—no crunch or residue, just touchable lift at crown and part.
- Simple Leave-In Application — Shake, apply two to three droppers to clean scalp, massage and let dry; use morning or night and style as usual—PowerCycle keeps working quietly between washes.
- Hypoallergenic & Dermatologist Tested — Formulated to meet sensitive-skin standards; this vegan scalp serum is patch-tested by dermatologists and safe for daily use on colour-treated or chemically processed hair. Gentle enough for sensitive scalps, powerful enough for advanced hair loss.
- Clinically Proven Results in Weeks — 100% of users experienced thicker hair diameter (+29% average increase). 89% saw improved density with 16% noticing longer, stronger hair. Visible volume and crown lift in 4-8 weeks vs. months with other treatments.
