Almost 90% of transplanted hairs are gone in 3 weeks. Is it normal? When I should expect them to grow? (Photo)

Dear Scsahay,Hello.  Shedding of hairs following your hair restoration procedure and is 100% normal.  You should have been informed of this prior to your procedure in a discussion brought up by your treating surgeon.Here's why: hair follicles are like little organs in the skin that do one thing: make hair. They are sort of like your nail beds at the base of each fingernail. However your nail beds produce fingernails continuously and without 'breaks' for the duration of your life. As in, you don't shed your fingernails every few months.Well, that's what's going on with the hair on your head. The hair follicle on the scalp is in the growth phase, or "Anagen" phase for many years (3-8 years) and is the phase most of the follicles on your head are currently in....growth phase. It's a fact that most people have about 100,000 follicles on their head (without hair loss), with each producing an average of about 2 hairs per follicle. Every month, 50 to 100 hairs on a person's head (with no hair loss) enter a regressive phase and then a resting phase, which lasts a total of about 3-7 months. These phases are called Telogen and Catagen phases, respectively. Every day people shed 50-100 hairs, and at the same time 50-100 hairs re-enter the growth, or Anagen phase. If a person has no hair loss, it looks the same all year round.The process of hair restoration involves the surgical transplantation of follicles from the permanent are to the areas of loss in a highly controlled, orchestrated fashion. When you look at the nitty-grit, technically the blood supply to the tiny follicles is being cut off, and the follicles are being stored a storage solution. This is not as good as a direct blood supply, so the chilling of the follicles (if it's done according to the strict Standards of Practice to which I adhere), the immersion of the follicles into a holding solution, and then the re-implantation of the follicle into it's new recipient site places a physiologic stress on the follicle. Like it had to run a marathon it had not trained for.In plastic surgery, hair follicle transplants are technically called "free tissue transfers," in that the tissue being moved about on the body does not remain connected to its blood supply, which is the norm in most every plastic surgical procedure performed today. As such, re-vascularization of the follicles becomes a major issue with hair restoration procedures, and in dedicated Centers, steps are taken to mitigate the many possible injuries to the follicles, including desiccation and perfusion-reperfusion injuries that so often plague organ transplants.In short, the physiologic stress placed upon the hair follicle during transplantation can often prematurely end the follicle's anagen (e.g.: growth) stage, and cause it to enter the regressive and resting stage. So a follicle 2 years into its 7 year growth phase (e.g.: anagen phase) may be sent into the regressive phase where the follicle sheds its hairs and appears to produce no hair. This is not a time to worry however, because if the grafts were well-taken-care of outside your body by competent, full-time technicians in proper biotech organ-preservative solutions, it will produce another strong terminal hair in 3-8 months. The follicles don't know they have been moved from the donor area, and this is what makes hair restoration a permanent solution to an incurable, progressive physiologic phenomenon. It is up to your hair restoration surgeon to replace the hair you've lost. It is up to you, the patient, to try to curb the rate in which your hair loss occurs. It's a team effort.

It is very normal to see shedding of the transplanted hair after your hair surgery in the first month.Up to 85-90 % will probably shredded . On the other hand what I understand you should neither did get any post operative instructions nor meet your doctor after the surgery.Please check with your physician for full detailed post operative instructions.

I am a bit surprised that you would ask these questions after a surgery.  Your doctor should have told you that most of your transplanted hair should fall out in one month.  You should expect to see results in 6 to 12 months.
