Dear john_ssThank you for writing in with your question. At 3.5 months following a procedure, you should just start to see the first few new follicles sprouting new hair. A certain percentage of the hairs should have just stayed where they were placed, and continued to grow where they were placed. This percentage will vary, depending on whether PRP was used in conjunction with your procedure, how long the grafts were outside your body (a function of the talent, experience, and dedication of your physician and his surgical team of technicians), among other factors. The hairs that shed out in the weeks following your procedure should return asynchronously from about month 3 to about month 8. Most patients experience a large growth phase in months 4-6 or so. However, you may be a late bloomer, and your hairs may experience their growth phase in months 5-9. I hope this information is helpful to you.
