When Does Root Regrowth Become Noticeable After Coloring?
Root regrowth is one of the most common frustrations after colouring, especially in hot climates, where sun exposure, humidity, pool days, and frequent hair washing can make your colour look “older” faster. Even if your hair colour looks perfect on day one, your natural roots will still grow in and eventually become visible.
At It's Beauty, professional colour services often include recommendations on techniques and aftercare so regrowth blends more naturally and doesn’t force you into constant salon appointments.
How root regrowth works (and why it feels so fast)
Hair grows from follicles at the scalp, and the new hair that appears will always be your natural shade unless you colour it again. For most people, average growth is around 1.25 cm per month, but it can be faster depending on genetics, age, hormones, health, and even season.
What makes it feel fast is contrast. If you dye your hair blonde and your natural hair is dark brown, even 0.5–1 cm of growth can look obvious in photos. The same goes for vivid shades like red, copper, pink, or silver; these colours create a strong visual difference at the root line.
Grey coverage is another category. Grey hairs reflect light differently and often look more noticeable even when the regrowth is minimal. That’s why clients covering greys tend to notice roots earlier than clients colouring close to their natural shade.
When does regrowth become noticeable: a realistic timeline
Most people begin to notice a change around 2–3 weeks after colouring. At that stage the regrowth line may be subtle, but it becomes visible around the parting and hairline in bright lighting, close-up photos, or mirror checks.
By 4 weeks, roots are usually noticeable in daily life, especially for high-contrast colour (dark base + light lengths), straight hairstyles, and clients with fast-growing hair. By 5–6 weeks, regrowth becomes obvious for most people and often starts affecting the overall “freshness” of the colour.
For grey coverage, the timeline often shifts earlier. Many clients need a touch-up every 2–4 weeks, depending on how dense the greys are and where they appear (temples and front hairline usually show first). For low-contrast colouring (for example, a shade close to your natural colour), you can often go longer without it looking messy.
