Hair Shedding After A Hair Transplant

Also known as “shock loss”, it is normal to shed your transplanted hair following an FUE hair transplant. This process starts at 1-2 weeks after surgery and is completely normal. Your new hairs will grow in their place in the next 8-12 months.

There are 3 instances of hair shedding that patients need to know about:

  1. Hair shedding of transplanted hair
  2. Hair shedding of non-transplanted hair
  3. Hair shedding in the donor area

Why does hair shed after surgery?

Hairs have a growth cycle, split into 3 stages- growth, transition and resting phases. The resting phase is the time when the roots shed their hairs. Hairs can move into the resting phase following the trauma of surgery. The main traumatic events the hairs goes through during the course of hair transplant surgery are:

  • The hair follicle being cut away and disconnected from blood supply
  • The hair follicle being re-implanted back into the scalp
  • Surrounding hairs being affected by incisions and anaesthetic

Hair shedding of transplanted hair

After a hair transplant, the implanted follicles and the attached hairs will stay in their new place for 1- 2 weeks. The follicles in this period will start to switch into a resting phase and will then begin to shed their hair. This shock loss can start as early as 10 days following transplantation. It can last up to 12 weeks.

hair shedding 2 weeks post hair transplant
At 2 weeks you can see some hair starting to shed in the transplanted hairline.
hair shedding 1 month post hair transplant
At 1 month following surgery most of the transplanted hair has been shed. There is minimal redness present in the operated area.

This process of hair shedding is expected and does not represent the scalp “rejecting” the implanted hairs.

hair shedding 3 months post hair transplant
At 3 months post hair transplantation, the hairs that have been shed are now starting to regrow. Over the coming months, this gentleman can expect good growth, with the final result evident at 8-12 months after surgery.

Hair shedding of non-transplanted hair

Some patients may notice that hairs that haven’t been transplanted can shed after a hair transplant. The risk of shedding non-transplanted hairs is increased if someone has a large number of thin or miniaturised hairs that sit in-between newly implanted hairs. Like transplanted hairs, these native non-transplanted hairs shed because their follicles also move into a resting phase following the trauma of surgery.

Shock loss of non-transplanted hair can occur from 2 weeks following surgery but can also occur months later. This process, although rare, self-resolves. And all hair that has shed should regrow.

Hair shedding in the donor area

Rarely, patients can notice shock loss in the donor area. This phenomenon is rare especially when a patient has been operated on by an experienced hair transplant surgeon. Donor hair shedding is temporary and the hair should grow back.

When will hair grow back after shock loss?

Hair grafts tend to shed between 2-12 weeks following surgery. After they have shed, the hairs should start to grow back over the next 4-12 months.

From 12-18 months following surgery the hairs should start to thicken, making the end result even better.

Can you reduce the risk of hair shedding after surgery?

Unfortunately, there is no proven way to reduce the risk of shock loss following surgery.

However, patients can safeguard against future loss by taking either Finasteride (men only) or Minoxidil (men and women).

Finasteride

Finasteride reduces the level of dihydrotestosterone in the scalp. This prevents hair loss and thickens hair in many men. Finasteride is a tablet you can take everyday or as advised by our Surgeons. You can read more about this medication here: Finasteride and Hair Transplant Surgery

Minoxidil

Minoxidil is a solution or a foam you can apply to thicken areas of thin hair. It also helps to prevent hair loss and can be used to help quicken the growth of hairs that have shed during shock loss. You can read more about this medication here: Minoxidil and Hair Transplant Surgery
