SickScience PowerCycle Exosome Hair Growth Serum 60mL — Lightweight, Vegan Scalp Treatment

PowerCycle blends biomimetic exosome delivery with targeted actives like caffeine, niacinamide and peptides to nourish the scalp surface and encourage stronger, thicker hair appearance. The formula is vegan, fragrance-free, hypoallergenic and silicone-free, so it fits into sensitive-skin and colour-treated routines while remaining lightweight and non-greasy.

How quickly will I notice reduced shedding or more volume?

Clinical testing reported measurable changes within weeks for many users: reduced visible shedding and improved density were observed faster than typical topical approaches. Individual results vary, but the serum is formulated for daily, ongoing use to build visible improvement over a short-term period.

• Reported density and diameter improvements in clinical trials within 4–8 weeks.
• Designed for twice-daily or once-daily leave-in application for consistent exposure.
• Non-sticky texture gives immediate soft lift at the crown while working long term.

What makes NX35™ exosome technology different from other serums?

NX35™ uses high-concentration exosome delivery to place supportive molecules—like caffeine and peptides—at the scalp surface, mimicking natural cell communication without using oil-based carriers or drug actives. The approach is intended to improve how actives reach the hair-root environment while keeping the serum lightweight.

• Billions of exosomes in a biomimetic carrier for targeted scalp delivery.
• Combines stabilised caffeine, niacinamide and peptide complexes for multi-target support.
• No silicones or heavy oils, so it absorbs quickly and won’t weigh hair down.

Is this safe for colour-treated or sensitive scalps?

PowerCycle is formulated without dyes, parabens or common irritants and has been patch-tested by dermatologists for sensitive skin. Its hypoallergenic, fragrance-free profile makes it suitable for colour-treated, chemically processed, and delicate scalps when used as directed.

• Dermatologist-tested and hypoallergenic for everyday use.
• Vegan, cruelty-free, and free from dyes and parabens.
• Gentle on colour-treated hair and suitable across textures.

How do I use the serum in my routine?

Application is simple: shake, apply two to three droppers directly to a clean, dry scalp, gently massage and allow to dry. Use in the morning or evening before styling; the formula remains active between washes so you can continue normal hair care without buildup.

• Apply to the scalp 1–2 times daily, focusing on thinning areas or crown.
• Massage until absorbed; leave in—no rinsing required.
• Compatible with other styling products and colour treatments.

Who is this for? SickScience PowerCycle suits men and women wanting a clinical-strength, non-drug option to support thicker-looking hair and reduced shedding. It is aimed at people seeking a lightweight, sensitive-safe serum that provides immediate cosmetic lift plus ongoing support for improved hair diameter and density when used consistently.
