Eyebrow Transplant: How Soon Will Cobblestones Appear? (photo)

Eyebrow transplants involve a technically different style of procedure compared to a typical hair transplant on the scalp. These eyebrow hairs have to be placed in an angle so that there isn't much tissue around the hairs.

When I do eyebrow transplants in my practice, I use a material called extracellular matrix (ECM) made by ACell. This material has been used to reverse or treat male or female pattern hair loss. I also use the same material in an injection form for eyebrow transplantation because it accelerates the healing process. Extracellular matrix reduces the amount of shock loss or hair loss soon after surgery and diminishes collateral hair loss considerably.

Bumps and cobblestones after a hair transplant are usually related to the size of grafts and the size of the slit that was made. This happens when hair is placed in a hole that is a bit smaller or when there is already hair under the skin which was overlapped by the transplanted hair. This is referred to as "stacking" and creates these bumps. In the normal stages of the healing process, the body also generates collagen that contributes to the bumpy appearance. However, these bumps eventually become softer and smoother which is a part of the normal healing process. Proper wound healing would take about 6 months or even up to a year.  I hope that was helpful to you, and thank you for your question.

Strange bumps at the root of the grafted hairs can be a normal part of the healing process with hair and eyebrow transplant. It is from edema of inflammation at the root of the hair and partly from may be skin/hair debris caught beneath the skin, or it may be newly growing hairs trying to push their way through. In any case, this should go away, but it may take time. Even up to several months. If it becomes a serious problem, definitely follow up with your surgeon.

Yes, this is often just part of the process.  However, it is not always the case and they can last a long time.  Overall, its still a good idea to go back in and have them looked at by your hair restoration doctor.
