10 Things to Know Before You Colour Your Hair

There's a moment that happens in every salon, every single week. A client sits down, pulls out her phone, shows us a photo of an impossibly buttery blonde, and says the four words we hear more than any others: "Can we do this?"

Usually the answer is yes. Sometimes it's yes, but not today. And every so often, that photo is a wig.

Look, colouring your hair is one of the fastest ways to feel like a brand new person. It's also a proper chemical process happening on something you can't pop out and replace. The gap between "obsessed with my hair" and "why is it orange" almost always comes down to what you knew walking in.

So here's the honest version. Ten things worth understanding before you book, from a Paddington salon that has fixed a lot of Sunday night decisions.

1. Your hair remembers everything you've ever done to it

This is the big one, and it's the thing that surprises people most.

Your hair isn't a blank page. Every box dye, every henna, every at-home bleach kit, every "just a little toner" from three years ago is still sitting in your lengths. It doesn't wash out. It grows out. Which means if you've got long hair, you could be walking around with four or five years of history attached to your head.

That history decides what's possible. Here's the rule nobody tells you: colour doesn't lift colour. So if you've got dark box dye on your ends, slapping a lighter dye over the top will do roughly nothing. You need lightener to shift it, and how that lightener behaves depends entirely on what's hiding underneath.

So when your stylist asks what you've had done, we're not making small talk. Tell us everything. The box dye from uni counts. Henna definitely counts, because it can react in weird ways with professional lightener, and it's one of the few things that can genuinely stop us mid-appointment. Nobody's judging you. We just need the map.

2. Your inspo photo is a direction, not a contract

Bring the photo. Please bring the photo. It's so much more useful than words, because "ashy blonde" means something completely different to every human alive.

Just know what we're actually reading in it. We're looking at tone, placement, and how much contrast you're drawn to. What we're quietly discounting is the golden hour lighting (which makes everything three shades warmer), the filter, the salon blow dry, the fact that she's got a totally different base colour to you, and yes, the very real possibility of extensions.

Here's the pro move: bring three photos you love and one you hate. Three shows us the pattern. The one you hate tells us where your line is, and honestly that's often the more useful photo. "Too warm", "too stripey", "too much contrast at the root" are the details that save an appointment.

3. Going lighter is a journey, not an afternoon

If you're starting dark and you want to be properly blonde, one appointment usually won't cut it. Not because we're trying to squeeze more out of you. Because hair can only take so much lift in one go before it starts to give up, and any stylist who pushes past that is handing you breakage with a smile.

A sensible lightening plan might be two or three sessions across a few months, landing somewhere lovely each time. You won't be wandering around looking half finished. You'll go through a run of gorgeous colours that get lighter each time.

The alternative? Demanding it all in one day is how people end up with hair that feels like chewing gum and has to be cut off. We'd much rather tell you the truth in the consultation than send you home with damage. Our blonde specialists will map the whole thing out upfront so you know exactly what you're in for.

4. Skin tone matters more than you'd think

That colour that looks unreal on your mate can look a bit off on you, and it's usually not the colour's fault. It's an undertone clash.

Quick test. If gold jewellery suits you and silver makes you look a bit unwell, you've probably got warm undertones, and you'll absolutely glow in honey, caramel, copper and warm brunettes. If silver is more your thing, cooler tones like ash, beige, mushroom and cool brunette will tend to flatter you. Neutral undertones are the lucky ones who can go either way.

There's a practical bit too that nobody mentions. Very cool, very pale blondes are unforgiving. They pick up redness in your skin, and they show every scrap of warmth the second it starts creeping back. Stunning, but a commitment.

Your stylist will look at your undertone, your eye colour, and your natural base all together. This is exactly the chat to have during your colour consultation, before anything gets mixed.

5. You're not booking a colour; you're starting a relationship with one

Colour isn't a one-off purchase. It's a subscription.

The second you walk out the door, your regrowth clock starts ticking. Hair grows around 1 to 1.5cm a month, so a high-contrast colour on dark hair will start making itself known at about four weeks, while a soft blended balayage can look completely intentional for four months.

This is the single most important thing to weigh up, and it has nothing to do with which colour is prettiest. It's about which colour actually fits your life. An all-over blonde on naturally dark hair is a real ongoing thing. A hand-painted balayage is designed from the start to grow out gracefully.

If you're time poor or watching your budget, just say so. There's almost always a version of the look you want that's built for lower upkeep, and we'd far rather make you that than watch you fall out of love with your hair by week six. We've broken the timing down properly in our guide to how often you can safely colour your hair, and if you want a realistic sense of how long each type of colour actually holds, we've covered that too.

6. Budget for the year, not the day

Following on from that, and let's be blunt about it: the price of your first appointment is not the cost of your colour.

The real number is that first appointment, plus your maintenance cycle, plus the home care that keeps it looking like it did when you left. A colour that's cheaper on day one but needs refreshing every four weeks can easily cost you more over a year than a pricier low-maintenance option you visit three times.

Work out the yearly figure before you decide. It genuinely changes what people choose, and almost always for the better. We've laid out realistic numbers, plus what pushes the price up or down, in our guide to professional hair colour costs in Brisbane.

7. Condition comes first. Always.

If your hair is already fragile, dry or quietly breaking, the answer to "can we lighten it" might be "not yet".

Lightener works by opening the hair's cuticle and dissolving the natural pigment inside. On healthy hair, that's a controlled process. On hair that's already been through it, already porous, already over-processed, it's like renovating a house with dodgy foundations. Everything you build on top is going to fail.

Here's how to tell your hair needs a repair phase first. It stretches when wet and doesn't spring back. It feels gummy or mushy with conditioner on. It snaps in the middle rather than at the ends. It won't hold a style no matter what you do.

The fix isn't dramatic, promise. A few weeks of the right in-salon treatments plus a tidy-up of your home routine can take hair from "not a candidate" to "absolutely, let's go". And bond builders used during the colour service protect the internal structure while we work. It's a short delay for a much better result. Worth knowing whether your hair actually needs protein or moisture too, because getting that backwards makes things worse.

8. Patch tests exist for a very good reason

Permanent and demi-permanent colours contain dyes (PPD is the usual suspect) that a small number of people are allergic to. Reactions are rare. They can also be serious, and they can show up out of nowhere in someone who's been colouring happily for years.

A patch test takes two minutes. A dab of product behind the ear or inside your elbow, left for 48 hours. If you're new to colour, coming back after a long break, or you've ever reacted to a temporary tattoo, hair dye or textile dye, flag it when you book so we can slot it in.

Bleach works differently and doesn't carry the same allergy profile, but it can irritate your scalp. So if you're sunburnt, you've scratched your head raw, or anything's flaring up, tell us. We'll change the technique or move the appointment.

Pregnant or breastfeeding? Current thinking is that occasional colouring is low risk, especially after the first trimester and with techniques that keep product off your scalp. That said, it's a personal call, and worth a quick word with your GP or midwife. We're hairdressers, not doctors, and we're very happy to work with whatever they suggest.

9. What you do at home decides how long it lasts

You can have a flawless colour done by a brilliant colourist and undo it in a fortnight. The usual culprits:

• Washing too often, too hot. Hot water swells the cuticle, and your pigment goes straight down the drain. Cooler, less often.

• Sulphates. Harsh detergents strip colour. Swapping to a sulphate-free, colour-safe shampoo is the highest impact change you can make, hands down.

• Heat styling with no protection. A straightener at 230°C is essentially cooking the tone out of your hair.

• The Brisbane sun. Our climate is not kind to coloured hair. UV oxidises pigment and turns cool tones brassy at speed.

• Chlorine and salt water. Pool chlorine is brutal on blondes. Soak your hair in fresh water before you get in, so it absorbs less pool.

Vivid reds and coppers fade fastest, because those molecules are physically bigger and don't hang on as well. Going red? Go in knowing you'll be back sooner. We've gone deep on all of this in our guide to why hair colour fades so fast.

10. The consultation is the best bit

If you take one thing from this whole list, make it this. The fifteen minutes before anyone touches your hair matter more than everything that comes after.

That's where we map your hair history, turn your inspo into an actual plan, set a realistic timeline, agree on the number, and close any gap between what you're picturing and what's achievable. Before it becomes a problem, rather than after.

At Tyco. A standard consultation is $50, and it comes straight off your service cost when you go ahead. It exists so nobody's guessing, and so you can go away and have a think with real information instead of a vague feeling.

Bring your photos, your hair history, your honest budget and your honest appetite for upkeep. Leave with a plan.

Quick answers

Should I wash my hair before a colour appointment? Not right before. Day-old hair is perfect, because your natural scalp oils give you a bit of protection, especially with lightener. Just skip the heavy oils, the dry shampoo build-up, and anything silicone-heavy on the day. More in our guide to preparing for your first colour appointment.

Can I go from black to blonde in one session? Rarely safely. Expect a staged plan over two or more appointments with recovery time in between. Anyone promising it in a single sitting is gambling with your hair.

How long does a colour appointment take? A root touch-up might be 90 minutes. Full foils: three to four hours. A big blonde transformation can run three to five. Ask when you book so you can plan your day.

Is box dye really that bad? For a one-off, all-over darker shade on virgin hair? It's fine. The trouble starts with repetition. Box dye is built to work on any hair type, so it's deliberately aggressive, and it stacks up unevenly on your lengths. That build-up is what makes future lightening slow, patchy, and expensive to sort out.

What are my options for covering greys? More than you'd think. Permanent colour gives you full, even coverage, while highlights or lowlights can blend greys softly so your regrowth is far less obvious. Which suits you depends on how much grey you have and how often you want to be back in the chair. We've compared them properly in our guide to grey coverage options.

Do I need a full colour every time, or just my roots done? Usually just your roots. If your ends still look good, a root touch-up is quicker, gentler, and cheaper than redoing the lot. Our guide to root touch-up vs full colour covers when each one makes sense.

How much does professional colour cost? Depends on the service, your hair length, and the stylist. Full pricing lives on our services and pricing page, and we've explained what drives the numbers in our Brisbane colour cost guide.
