According to Pattern

Repigmentation is evaluated according to peculiar pattern of pigmentation onset after the particular treatment  

Perifollicular: Usually seen after medical management over the the patch with black hairs. Small dots of pigments appear at the root of hairs, gradually increase in size and join together to become bigger patch of pigmentation. Speed of pigmentation is faster. Sometimes seen after cell transplantation and micro needling techniques.
Diffuse: This is also seen mostly seen in hairy area or in the patch after cell transplantation. Can also be outcome of medical management and microneedling techiniques. Suddenly a bigger area of pigmentation starts visible. This is also faster version of pigmentation
Marginal: The pigmentation starts from the border. The size of the patch reduces but shape sometimes remain stagnant. Slowest version of pigmentation but very stable version of pigmentation. Can be possible due to all types of treatments. Observed over the joints and acral area with no reservoirs.
Combined: Combination of 2 or 3 of above mention patterns can occur. Usually observed over larger patches.
Refractory: In this variety one can see darker borders of the vitiligo patches, along with darker islands of pigmentations which don’t increase in size despite of continued medical treatment. The resistant white area remains white or reddish pink. This occurs in a patch with limited reservoir which cannot contribute required pigment cells to replenish the lost ones.
