Does Hair Growth Happen All at Once or in Stages after Hair Transplant Surgery?

This below question was asked by a member of our Hair Loss Social Community and Discussion Forums and answered by recommended hair restoration surgeon Dr. Ali Emre Karadeniz.

After a hair transplant, when the hair starts to sprout at 3 months, will the hair come out of the skin all at once? Like all the grafts that were planted? Or, will they come out little by little and not at once.

I had read somewhere that all the follicular units that are viable and can grow hair, sprout at once between 3 and 4 months post-op and after that, it’s basically thickening and maturing.

It is basic information, but there is no harm in repeating that follicles are in asynchrony at the time of extraction, thus starting to grow at different times after hair transplantation.

They do not grow all at once at 3-4 months although there is a dominance of hair growth either at 5-7 or 8-10 months. Depending on the biology of each patient, totally new hairs may sprout after 12 months.
