Congratulations and very happy . By month 3, the new hairs begin “popping” through the scalp. By the end of month 3, approximately 30% of the hairs have penetrated through. 40% have come through by month 4, and 50% by month 5. By 6 months, approximately 60% – 70% of the new hairs have fully penetrated through the scalp. By the 9thmonth, approximately 90 – 100% of the hairs have “popped” through the scalp, and most of the changes of a hair transplant from that point forward are due to maturation.
