How Does 24K Gold Micro-Infusion Work?
Ultra-fine 24K gold needles are loaded with serum, then stamped into the scalp to open thousands of invisible micro-channels. Your regrowth serum travels through them and reaches the follicle directly — instead of sitting on the surface like foams and sprays.
How A Session Works
Five steps, 2–3 nights a week. No clinic, no prescription, no mess.
Wash your scalp and dry it fully before you begin.
Twist open the system, fill it with serum, then close it tightly again.
Leave the device upside down for 2 minutes so the gold needles fully absorb the serum.
Gently stamp across the hairline, crown and temples with 50% overlap — 2–3 passes per area.
Apply any remaining serum to thinning areas and leave overnight. Don’t wash your hair for at least 6–8 hours.

The Micro-Infusion Science, Without the Jargon.
Follicles sit millimetres below the skin. Anything that stays on top of the scalp never reaches them. Micro-infusion opens a temporary path — the serum goes in, the channels close, the follicle gets fed.

Questions, Answered
The 24K gold micro-needles create thousands of tiny channels in the scalp, letting the regrowth serum reach the follicle directly rather than sitting on the surface.
Many customers notice less shedding within a few weeks and fuller-looking density around the 8–12 week mark. Hair grows on its own cycle, so consistency matters.
No. The needles are ultra-fine and used at home with light pressure. Most people describe it as a gentle tingle.
TREVO is designed for all hair types and textures. It targets the follicle environment, which is the same regardless of hair type.
Two to three 2-minute sessions per week for three weeks, then a full week off so your scalp recovers. You use one serum vial per week, and each kit is built around that cycle.
A full 90-day money-back guarantee. If you don’t love your results, send it back for a complete refund — no questions asked.
