High dosage. Incredible results.

It’s all in the DOSETHEORY.

Your hair deserves formulas that actually do what they say, not just flaunt a “hero” ingredient that’s barely there. DoseTheory is here to deliver exactly that.

Proudly developed in New Zealand, our formulas lead with high-impact, transparent doses of on-trend hero ingredients that deliver results you can genuinely see and feel. While some brands love to hero an ingredient that’s sitting at 0.01% (hello, pixie dust), we don’t play that game.

We use science-backed extracts, ceramides, hairceuticals and clinically proven actives in percentages actually worth talking about. Radical transparency, real results and formulas you can trust.

“I started using this product and instantly saw my hair was shiny and not too heavy. I struggle with dry frizzy hair and oily roots. This product made my hair feel clean and hydrated without weighing it down. Will definitely keep using and would recommend.”
