From dark to light in one appointment- the honest truth - Hair To Go With Derry's Margaret Doherty

Sometimes the answer is yes. Sometimes the answer is… not exactly. And that’s where honesty and experience matter.

Going from dark to light isn’t just about putting a lighter colour on top. Hair doesn’t work like paint. You can’t simply cover dark with blonde and expect magic. Lifting colour means removing what’s already there — and that process depends entirely on what your hair has been through before you sit in the salon chair.

If your hair is natural and untouched, the journey is usually smoother. Virgin hair lifts more predictably because there’s no artificial pigment sitting inside it. But if there are years of box dye, dark glosses, build-up from home colouring, or even repeated salon colours layered over each other, that’s a completely different starting point.

Every layer of colour leaves something behind.

Dark dyes, especially box dyes — are the most stubborn. They build up on the mid-lengths and ends over time. So when we begin to lift, the roots might move quickly while the ends need a lot of work. That’s when people start to understand why it isn’t always a one-appointment transformation.

As a hairdresser, I can only take the hair to a certain level in one day, safely.

Yes, technically we can push hair further. But at what cost? Dryness, breakage, snapping? A healthy blonde always looks better than a damaged blonde. My job isn’t just to lighten your hair — it’s to protect it.

That’s why consultation is everything.

When someone shows me a bright, creamy blonde photo and their hair is currently dark brown with years of colour on it, I have to be realistic. I will always explain that I don’t fully know how your hair will react until we begin lifting. Hair can surprise you, sometimes in a good way, sometimes not.

No hairdresser should promise an exact shade before seeing how the lift behaves.

I can estimate. I can give you a professional expectation. But until the colour starts to break down, I don’t know whether we’re dealing with warm undertones, red build-up, uneven saturation or previous overlapping.

Sometimes we get further than expected and everyone leaves with a smile on their face.

Sometimes the first appointment is about removing darkness safely, improving tone, and setting up the second session. And that’s not failure — that’s a process.

Good colour work is often a journey, not a jump. The healthiest transformations happen when there’s trust between client and stylist. Trust that I’m not holding back, I’m protecting your hair. Trust that I want the best result long term, not just for one Instagram photo.

So can we go from dark to light in one appointment?

Sometimes, yes. But the real goal isn’t just lighter hair. It’s hair that’s still strong, shiny and healthy when we get there. And that’s always worth doing properly.

We’re based at Margaret Doherty and Co, Unit 2 Springtown Industrial Estate BT480LY, Derry
