Quoted as “renowned texture expert, Zoltan” in Vogue India and Vogue Italy (2018), discussing the science of pH-neutral straightening treatments.

“They’re pH neutral and made without ammonium thioglycolate (the thing that strips it dry). Check with your salon and if the product is pH 7, then go for it — they can even be used on bleach and create silky, shiny locks.” — Vogue India & Vogue Italy
