NO BRANDS. NO BULLSHIT. NO LIMITATIONS
HAIR COLOUR EDUCATION
Helping hairdressers understand the why behind colour. Through brand-neutral education, I simplify hair science, colour chemistry, and colour theory so you can make better decisions with confidence, not guesswork.
About Chaulk
WHAT WE DO
Simplify hair science, colour chemistry, and colour theory so hairdressers can make confident decisions based on understanding, not guesswork. Through brand-neutral education, I teach the knowledge that’s often overlooked in traditional brand training—helping you understand not just what works, but why it works.

HAIR COLOUR NERD, EDUCATOR & RULE BREAKER
SARAH SPIERS
With 30+ years behind the chair at top London salons like Trevor Sorbie and Brooks & Brooks, I bring serious experience – and an even deeper curiosity. A lifelong questioner, I’m obsessed with the “why” behind hair colour, blending science, chemistry, and real-world practice to elevate the craft.
Frustrated by the surface-level education in most salons, I carved my own path – studying outside the industry and building a unique, science-driven approach to colour.
Now based by the sea with my trusty dog Seymour, I run Chaulk Education – a no-fluff, brand-neutral platform that simplifies colour theory and helps hairdressers level up with confidence and clarity.
