"Popping" Timeline*:
-Month 3-5: Hairs begin popping through surface
-Month 5: 50% of hairs popped or penetrated surface
-Month 6: 60% popped
-Month 7: 70%
-Month 8: 80%
-Month 9: 90% - 100%; biggest changes in overall appearance from this point forward are usually do to maturation and not new popping.
*As with the maturation timeline, this is a rough estimate and no two patients will be the same. Being advanced or slow on this timeline also has no bearing on the final result and a hair transplant really shouldn't be evaluated in full until at LEAST the 12 month mark.
