EP394: Hair Colour Ingredient Truths with Ursus Schweitzer

Are ‘no-smell’ colours safer? Is ammonia the villain—or the workhorse no one wants to admit they need? If headlines are steering your decisions, this myth-busting chat could save your results and your reputation.

Brought to you by Wella Professionals UKI, we’re joined by Ursus Schweitzer—an R&D product developer who bridges the lab and the salon floor. He observes how products are really used, then translates complex chemistry into clear, salon-ready truths.

We dig into true ingredient awareness: what to actually pay attention to, where misconceptions begin, and how to talk about them with clients. Expect a straight-talking dive into ammonia vs MEA (function, performance, purpose), the reality of silicones, parabens and sulfates, and how to handle concerns with confidence. Plus, a future-facing tease on how ingredient innovation is evolving—without giving the game away.

Why you need to listen:
