Make colour last longer
Colour and balayage don't lose their depth in a day, but wash by wash. We show you what protects the tone and how to tell when your roots need attention.
In brief
Longevity in four sentences
What keeps the tone going
- Every hair wash costs colour pigment – washing twice instead of five times a week noticeably extends that fresh look.
- Balayage grows out softly and needs touch-ups less often than a fully coloured root section.
- Heat from hairdryers and straighteners opens the cuticle layer; a heat protectant before styling is the smallest effective step.
- Copper-red and cool ash tones fade faster than natural shades – that's what pigmented at-home care is for.
Causes
Four reasons colour fades
Colour pigment sits within the hair fibre and is washed or bleached out a little every day. Four factors make the biggest difference here.
Washing
Warm water and heavily foaming shampoos cause the cuticle layer to open, letting pigment dissolve away with the lather. So the biggest lever isn't the product, but how often you wash and using lukewarm rather than hot water.
Sun
UV light bleaches out colour pigment and pulls especially cool tones towards brassy. In Hamburg summers this mainly affects the top layer and parting – exactly the section you see first.
Heat
Hairdryers on the highest setting, straighteners and curling irons work at well over 150 degrees. Without heat protection the fibre becomes porous, and a porous fibre holds pigment less well than a closed one.
Care products
Deep-cleansing shampoos, silicone-based treatments and products with a high alcohol content attack the colour. At your appointment we'll tell you which care products suit your tone and which break it down faster.
Everyday care
What protects the colour
None of these points call for a whole new routine – they're small changes that together make the weeks between two colour appointments more pleasant.
- Wait 48 hours after your colour appointment before the first wash – that's how long the cuticle layer needs to close again.
- Wash lukewarm and rinse with cool water instead of showering hot.
- Massage shampoo into the roots only – the ends get cleaned anyway as you rinse.
- Use a colour-preserving, sulphate-free shampoo and avoid deep-cleansing products between appointments.
- Always apply a heat protectant before using a hairdryer, straightener or curling iron.
- Cover your hair in strong sun or use a leave-in with UV filter.
- Before swimming in chlorinated water, saturate the ends with a leave-in or oil, then rinse thoroughly afterwards.
- Top up cool and red tones every two to three washes with a pigmented treatment.
After your appointment
The first two days matter most
During this time the cuticle layer closes again and locks in the fresh pigment. Waiting this long means visibly more depth in the tone later on.
Intervals
When the regrowth is due
Hair grows an average of about one centimetre per month. How quickly this becomes noticeable depends less on speed than on the contrast between your natural hair and your chosen tone.
Colour right to the root
- Covers grey hair completely and gives an even tone from root to tip
- Result is fully predictable from day one
- The regrowth line shows up sooner, because natural hair and colour sit directly against each other
- Needs regular appointments, otherwise the boundary becomes a visible edge
Balayage through the lengths
- Grows out without a hard edge, because the lightening only starts below the root
- Longer intervals between appointments possible
- Does not cover grey hair at the root
- Lightened sections need more moisture care and occasionally a toner against brassiness
How to tell it's time
- A clearly visible line runs along the parting – this section always shows the regrowth first.
- The temples look lighter or greyer than the top layer.
- The tone only looks good under artificial light, but flat in daylight by the window.
- Bleached lengths turn yellowish, cool tones lose their depth.
- When tying your hair back, a visible colour step appears where the hair folds over.

The root touch-up appointment step by step
So you know what to expect: here's how a root touch-up colouring works with us, from the consultation at the window to the aftercare you take home with you.
For a root touch-up colouring, plan on around 90 minutes; for a balayage refresh, two to three hours. It's best to come with dry hair and without freshly applied styling products.
We look at your hair dry and in daylight by the window: how far the regrowth has grown out, how the length compares in tone, how much grey needs covering. This tells us whether a simple regrowth colour is enough or whether the lengths also need a gloss refresh. We note down your formula so the next appointment goes smoothly without having to reassess from scratch.
The colour is mixed fresh, matched to your hair structure and the desired depth. We then part the hair into narrow sections, parting by parting. This careful sectioning is why no dark edges appear later: the colour sits only where regrowth is present.
Using the brush, we apply the colour precisely to the regrowth zone, around one centimetre wide, without overlapping the already coloured length. Overlap is the most common cause of banding, meaning visible darker stripes in the hair. We work on the forehead and temples last, since body heat speeds up development there.
Depending on the product, the colour processes for 20 to 40 minutes. We check a test strand in between to see whether the tone has taken, extending or stopping the process accordingly. For stubborn grey hair at the temples, a short touch-up may be needed, which we discuss with you before doing it.
After emulsifying and rinsing out, a treatment follows that brings the hair's pH back to a slightly acidic level. This closes the cuticle layer, leaving the surface smooth again – the prerequisite for colour pigments staying in the hair and light being reflected evenly.
Finally, we trim the ends if you like, blow-dry into shape, and show you which products suit your colour: a colour-protecting shampoo without sulfates, a mask for the lengths, and for cool tones, a silver rinse as well. We book your follow-up appointment right away so the rhythm isn't broken.
