How vitiligo skin can repigment
Color can come back as small dots around single hairs, not as a patch filling in like paint.
Four-frame mechanism illustration
Color can return in dots and islands
This simplified drawing explains a common pattern. It is not a prediction, a treatment result, or a photograph of a person.
1. A patch before change
A simplified patch is shown before visible color returns.
2. Dots near follicles
Small color dots may appear around hair follicles inside the patch.
3. Growing islands
Some dots can widen into small islands while the patch still looks uneven.
4. Islands move together
Some islands may meet. The final pattern and amount vary by patch and person.

What this illustration cannot tell you
It cannot predict whether, where, or how much color will return for you.
A simplified follicle view
Research describes pigment-cell reserves in hair follicles as one source of color that appears around hairs. Other repigmentation patterns can also occur.

Knowing that in advance can make an odd-looking middle stage less surprising.
It is also okay to decide that tracking each change adds stress. Photos, treatment, a pause, and no active treatment are all choices.
Keep the question, not the frame
The four frames are a drawing of a pattern, not a picture of your skin and not a forecast. Nothing on this page is stored or sent anywhere.
The question under the frame is the part worth keeping. Save it and it joins your list on My next conversations, which prints on one page.
The science in plain words
Hair follicles can hold reserves of pigment-making cells.
When repigmentation happens from that reservoir, small areas of color can appear around individual hairs and spread outward.
Where the hairs in a patch have gone white themselves, DermNet describes that reserve as destroyed, and areas with white hair as responding poorly. It also describes a second possible reserve at the border of a patch, so this is a poorer route rather than a closed one.
The illustration is simplified. Skin can show more than one pattern, and a pattern does not promise a final result.
Lived experience - useful, real, and different for everyone
The in-between can look uneven
Dots, islands, and mixed tone can feel different from the clean white patch you knew.
Some people find that hopeful. Some find it harder to look at. Neither response is wrong, and you can decide what amount of change would feel worthwhile to you.
This page does not promise that uneven color will blend later. Ask what the care team has seen in your areas and what remains uncertain.
Ask your care team Keep safety, treatment, and irreversible choices with the team that knows your health, skin, and goals.
What you can do
Choose a way to notice change that does not take over your day.
- Ask what early change might look like in the areas you care about.
- If you use photos, keep the lighting and angle as steady as practical.
- Agree on when the plan will be reviewed without setting a target on this page.
- Pause tracking if it is making you feel worse.
Ask your care team Keep safety, treatment, and irreversible choices with the team that knows your health, skin, and goals.

What this source supports
Supports pigment-cell precursor populations in hair follicles and their observed proliferation, migration, and differentiation in studied NB-UVB-treated human vitiligo skin.
What it does not support
It cannot predict whether a patch will repigment, how much color will return, or how long change will take for one person.

What this source can and cannot tell you
What this source supports
Supports a dermatology reference account of vitiligo. It supports that loss of hair color is called leukotrichia or poliosis. It supports that this may affect the scalp, eyebrows, eyelashes and body hair in 10 to 60 per cent of patients. It supports that it does not correlate with disease activity. It supports that it could be a predictor of poorer response to therapy, because the melanocyte reservoir in hair follicles is destroyed. It supports that treatment is most successful on the face and trunk. It supports that hands, feet, and areas with white hair respond poorly. It supports that new patches are more likely to respond to medical therapy than long-standing ones. It supports that the hair follicle is the main source of pigment restoration. It supports that another potential reservoir can be at the borders of the white patches. It supports that poor prognostic indicators include longstanding disease, leukotrichia, mucosal involvement and the Koebner phenomenon. It supports that segmental vitiligo often has an irregular border with leukotrichia. It supports that leukotrichia and halo naevi are listed as predictors of transformation into the mixed variant. It supports that the Vitiligo European Task Force assesses five sites: head and neck, trunk, arms, legs, and hands and feet. It supports that its grading runs from 0 for normal pigmentation to 4 for complete hair whitening. It supports that its clinical assessment form records sex, age, duration of disease and age of onset. It supports that premature hair greying has been described but that the association is still uncertain.
What it does not support
It is a dermatology reference page, not a trial and not a measurement of any one person. Its 10 to 60 per cent figure is a span, stated on the page without a study behind that span. Its wording on response to therapy is that hair whitening could be a predictor, which is weaker than a finding. Nothing on it predicts whether one patch or one hair will repigment, how much color returns, or how long that takes. It sets no treatment, no dose, no schedule and no product. It does not diagnose white hair on a reader as vitiligo. Its author line is dated August 2022 and the page records a last review of 11 July 2023, so parts of it are older than the date registered here.
