Still Standing At The BackWash Wondering Why Your Colour Didn’t Do What You Planned!
CSI: Colour Science Investigation is for hairdressers who love colour and are ready to replace the guesswork with a system that actually makes sense.
You’re Probably Feeling…
No matter how many formulas you’ve memorised, you still get to the basin with that little knot in your stomach… is this actually going to do what I think it will?
You’ve done the education, watched the tutorials, asked everyone you can—and it helps… until the next tricky client sits down, and you’re back to guessing and tweaking.
Because the problem is, deep down, you’re questioning yourself—wondering if you can trust what you see. Every doubt chips away at your confidence bit by bit.

I Know Exactly What That Feels Like…
Standing at the basin, looking at the hair… and feeling that doubt creep in.
Over 30 years behind the chair — and I still had moments where it looked right… but I knew I’d chased it.
Lifted it. Toned it. Tweaked it. Saved it.…but I wasn’t in control and that started to bother me.
I knew formulas. I knew technique. So why was I still guessing? Because I didn’t fully understand what the hair was about to do.
Once I did everything changed. No more chasing. No more panic toning.I knew what was coming before I even picked up a bowl.
That’s CSI.
Not more doing… just knowing enough to stop guessing.

Picture A Normal Saturday…
Full column. Client wants lighter. Cool. Ashy. Two years of box dye.
Before? Please don’t go orange. Now? You’re already ahead.
You read the hair. You know what it’s going to do. You know how to handle it.
So you mix with a reason not a hope and you get what you planned. Not luck. No second-guessing. No panic toning.
Big colour jobs stop feeling risky. You’ve got a process not a guess and you can actually explain what you’re doing.

CSI Is…
30+ years behind the chair. Thousands of colour services.
Not product systems. Not guesswork.
Actual understanding of how pigment behaves.
You’ll learn to think the way I do behind the chair.
.
The CSI Framework…

The CSI framework isn’t a collection of colour theory slides or formulas. It’s a way of thinking you’ll use every time you’re at the basin.
Here’s how C.R.I.M.E works
C — Canvas
What you’re starting with.
Level, history, porosity, previous colour.
You’ll learn to properly read the hair before you mix — no more assumptions.
R — Residue
How the hair will behave when colour or lightener hits it.
What will lift. What warmth will show. Why toner behaves differently.
I — Investigation
The target.
Not a screenshot. Not a guess.
A clear understanding of what the hair is actually going to do.
M — Method
Your approach.
Placement, formulation, process — decisions based on logic, not habit.
E — Execution
How it’s applied, timed, and controlled.
Work through all five and you stop reacting to results…and start predicting them. That’s the shift from
“let’s see how this goes” to “I already know where this is going.”.

Is CSI Right For You?…
It is If...
- You still have that “hope this works” moment at the basin.
- Your results aren’t as consistent as they should be.
- You want to understand colour — not just follow formulas.
- You’ve ever thought, I reacted to that… I didn’t predict it.
- You’re done guessing and want a process you can trust.
It’s not for you if:
You’re happy winging it — and the odd unpredictable result doesn’t bother you.
You want formulas, recipes, or brand-specific training.

Frequently Asked Questions
How much time do I need each week?
The modules are short and practical — most students find they can work through a lesson and apply it with a client the same day. You set the pace.
How is the course delivered?
Pre-recorded lessons you can access anytime, plus CSI worksheets and analysis tools to use in the salon. There’s also a student space to ask questions and talk through real colour situations.
