In todays show we’ll be talking about something there’s no great controversy about – screening for allergy.

It’s not controversial as we all need to do it, and the good businesses do. It’s also not controversial to say it’s one of the least popular parts of a salon’s operation. It’s not controversial either to say not enough people understand the issue well enough to make informed choices. So I’ve invited two amazing guest onto the show to talk about it.

This is the first time we’ve have two world renowned guests from completely different industries in one show. Legendary colourist Sophia Hilton is joined by Dr David Basketter, expert in hair colour toxicology, to talk allergy screening.

Far from being complicated, Sophia’s transformed the way Not Another Salon screens for allergy into an easily recognisable badge of quality for her thriving business. While supercharging colour convenience and unlocking creative freedom. This always brings up a scientific debate, but we knew that already, so David’s with us to get the facts straight on the science supporting Sophia’s approach. Visionary as always, Sophia’s cracked it in her business.

I don’t know any colourists with more followers than Sophia or scientists with more literature citations on hair colour than David! Thats why this conversation is the most informative and engaging listen you can get on why we need to screen for allergy using the highest standards possible. Let’s dive in!
