I dyed my hair the same colour as my friend — why did it turn out different?

Because your base colour, hair condition, and porosity aren't the same. The identical formula lands on a different canvas, so a different result is completely normal.

My hair is black and I want it much lighter — can it be done in one session?

Usually not. Dark hair with heavy melanin has to be lifted in stages. Rushing it in one go risks breakage and off-tones; building it over a few visits is safer and gives a nicer colour.

My fresh colour faded really fast — why?

Usually because the hair is very porous and can't hold pigment, combined with aftercare like very hot water or harsh shampoo. Use colour-safe products and strengthen the hair alongside.

Should I wash my hair before colouring?

You don't need it squeaky clean the same day, but avoid heavy wax or spray beforehand — residue makes colour take unevenly.

Why Your Hair Colour Doesn't Match the Photo (and How to Avoid It)

Hair colour came out different from the photo? The 5 real reasons — hair condition, product build-up, lighting, timing — and how to get closest to your target.

When your hair colour comes out “nothing like the photo,” it’s rarely because the stylist grabbed the wrong tube. It’s because everyone’s starting point is different: your existing colour, your natural melanin, your hair’s condition, and whatever is built up on the strands all shape the final result. Add the stylist’s skill in reading hair and mixing the formula, plus the conditions on the day, and the same recipe can land differently on every head. The good news is that almost every cause is preventable once you understand it before the colour goes on.

A reference photo is a “target,” not a “guarantee”

The photo you bring in is a colour that happened on someone else’s hair — with their base shade, their hair condition, even their lighting. A good colourist treats it as a direction, then judges how far your hair can travel toward it in a single visit. Some looks are a one-session job, some have to be built over several visits, and some simply aren’t right for your hair as it is today. Understanding this upfront is what saves the most disappointment.

The 5 main reasons colour misses the mark

1. How the stylist reads hair and chooses the formula

Colouring is colour theory meeting chemistry. An experienced colourist can see whether your hair hides warm or cool undertones, how much of an opposing tone is needed to cancel unwanted orange or yellow, and where to set the base level before the target shade goes on. Misjudge any of that — or pick the wrong developer strength — and the result drifts from the plan immediately.

2. Every person’s hair is different

Before an ambitious colour, a stylist should run a strand test to see whether your hair truly lifts and holds pigment the way the goal requires. Fine or weakened hair often grips colour poorly, so it takes unevenly or fades fast. A proper strand analysis is what decides how realistic your target really is for your hair right now.

3. Residue and build-up on the hair

Silicones from conditioners, wax, spray, and even mineral deposits from water can coat the hair so colour can’t absorb evenly. The result is patchy — darker in one spot, lighter in another — from a single formula. Prepping the hair clean matters as much as the colour itself.

4. Severely damaged, porous hair

Hair that has been heavily bleached or chemically processed becomes highly porous: the cuticle stays open and can’t hold pigment, so the colour rinses straight out and leaves a pale or off shade. This usually calls for rebuilding and rebalancing the hair first, then choosing a formula that helps lock pigment in longer.

5. Conditions and timing during the service

These three matter more than people expect.

Lighting should be neutral white or natural daylight. A room that’s too yellow or too blue makes the stylist read the colour wrong and adjust the formula in the wrong direction.
Temperature — heat speeds development, cold slows it — so processing time has to flex with the real conditions on the day.
Processing time and lifting — dark hair with heavy melanin has to be lifted to a light enough base first. If the base isn’t at the right level, whatever goes over it turns muddy or shifts off-tone.

Your own choices matter too

Colour often goes wrong because a client changes their mind mid-service — switching tone after the formula is already mixed — or starts from a place that fights the goal, like box-dyed black hair asking for platinum in a single visit, which is nearly impossible and risks breakage. Skipping aftercare also lets a colour that looked perfect on day one fade or shift far sooner than it should.

How to get as close as possible

Choose an experienced colourist and give the consultation real time before anything begins.
Bring photos from several angles and lighting, and name both the colour you want and the ones you don’t.
Listen to your stylist about your hair’s limits; if it needs several sessions, plan it in steps rather than forcing it in one.
Care for it afterward with colour-safe products (see how to keep your colour vibrant for longer). Bond-building systems like Olaplex and salon treatments such as Milbon and Schwarzkopf help pigment last and keep hair healthy between colour changes.

At FMG, every colour service starts by reading your hair’s real condition first — because a shade that lasts and suits your hair matters more than one that only looks good on day one. See the colour menu & prices and drop by either branch for a consultation.
