How many weeks before the wedding should you dye your hair?

Short answer

Dye your hair two to three weeks before the wedding. This gives colour time to settle and look natural, and allows for any fixes if needed. Avoid dyeing in the final week, as results can be unpredictable and stress can affect the outcome.

Plan to dye your hair two to three weeks before the wedding. This timing lets the colour soften and blend, so it looks more natural in photos and under different lighting. It also gives you a buffer if the shade is too strong or you want a small adjustment.

If you are trying a new colour or a dramatic change, do a patch test and a trial strand at least six weeks ahead. That way you know how your hair reacts and how the colour fades. For root touch-ups on an existing colour, one week before is usually fine, but keep the formula the same as before.

Avoid dyeing in the final few days. Your scalp can be sensitive from stress, and any mishap will be hard to correct in time. Also, freshly dyed hair can look flat or too shiny in photos. If you need a last-minute fix, use a colour-depositing conditioner or a temporary root spray instead of a full dye.

Remember that your hairdresser’s advice matters most, especially if you have previously coloured, bleached or permed hair. Book your appointment in the morning so you have the rest of the day to see the result in natural light. And always tell your stylist about any new products or treatments you have used recently.
