Discovery is Inochroma’s learning hub for people exploring grey hair care with sensitive scalps. If you’ve experienced irritation from traditional dyes, feel unsure about labels like PPD-free or ammonia-free, or want natural-looking results without harsh regrowth lines, this is where clarity starts.
Our guides explain how grey hair behaves differently, why some colour systems cause discomfort, and how approaches like grey blending, no-mix colour, and low-maintenance routines can reduce stress on the scalp. Each article is written to help you decide what works for you — before you commit to any routine.
Explore dermatologist-style patch tests, PPD-free and ammonia-free routines, and no-mix grey blending.
Is PPD-free right for me? Start with a 24-hour patch test; if you’ve reacted to oxidative dyes before, PPD-free/no-mix systems can reduce irritation risk.
How often? Weekly touch-ups keep tone even while fade stays soft with no harsh demarcation lines.
