SickScience PowerCycle Exosome Hair Growth Serum 60mL — Lightweight, Minoxidil-Free Scalp Treatment for Fuller-Looking Hair

SickScience PowerCycle is a lightweight leave-in exosome scalp serum formulated to support thicker, fuller-looking hair without minoxidil or heavy oils.

This serum uses the brand's NX35™ exosome technology to deliver a blend of biomimetic actives — including caffeine, niacinamide and targeted peptides — to the scalp surface. Designed for daily, leave-in use, the 60 mL bottle is vegan, fragrance-free and formulated to be gentle on colour-treated and sensitive scalps while adding instant touchable volume and longer-term support for hair diameter and density.

How does PowerCycle help if I notice thinning at the crown?

The formula is designed to sit on the scalp and hair fibres, giving immediate visual lift while supporting structural strength over time. Users report noticeable improvement in diameter and visible density after consistent application.

• Leave-in liquid texture for root lift and non-sticky volume
• Coats strands to create soft, touchable fullness
• Works alongside your styling routine — dries clear, no residue

What is NX35™ exosome technology and why does it matter?

NX35™ is SickScience’s platform that uses high concentrations of exosomes to help deliver scalp-targeted ingredients. It’s engineered to mimic natural signalling and to place key molecules where they can support hair fiber appearance and scalp environment.

• Delivers caffeine, niacinamide and peptides to the scalp surface
• Biomimetic approach intended for scalp compatibility
• Formulated without oils or drug actives for lightweight feel

Is this safe for sensitive or color-treated hair?

PowerCycle is formulated to be hypoallergenic, fragrance-free and dermatologically patch-tested to meet sensitive-skin standards. It avoids silicones, dyes and parabens, making it suitable for most textures and chemically treated hair when used as directed.

• Vegan, silicone-free and dye-free formulation
• Patch-tested by dermatologists for tolerance
• Suitable for daily use on colour-treated and processed hair

How do I add PowerCycle to my routine and what results can I expect?

Apply two to three droppers to a clean, dry or towel-dried scalp, gently massage, then allow to dry before styling. It’s designed to work between washes to support strand thickness and visible density over weeks of consistent use.

• Simple leave-in application, morning or night
• Non-greasy finish—style as usual after drying
• Designed for ongoing use to support fuller-looking hair over time

Who is this for: PowerCycle suits anyone seeking lightweight, non-drug scalp support to improve hair diameter and visible density—people with early thinning, those who want a fuller part or crown, and anyone preferring vegan, fragrance-free formulas. It’s appropriate for both women and men, and for hair that has been coloured or chemically treated. If you have specific scalp or medical concerns, consult a professional before starting a new topical routine.
