Eyebrow transplant; is less than 100 grafts possible?

It is up to the doctor.  There is no set rule.  There is no minimal requirement.  Eyebrow surgery may take less than 100 grafts, even less than 50 grafts. Each patient is different.The issue is what the doctor will charge for surgery.  There is usually a minimum fee.

The average number of grafts needed for eyebrow transplantation tends to range from 50-325 grafts. It is certainly possible to undergo this type of surgery with around 80 grafts to achieve your desired outcome and look your very best. Using a very high number of grafts may produce a harsh looking result. 
If you would like a smaller number of grafts, try to find a doctor who can accommodate your needs through a cost structure along these lines.

I have included a link and video with more information below. 

You can put many or as few hairs as needed, however, for many hair clinics, there is a minimum to cover the cost for supplies, time, staffing, equipment and followup.  You may be able to find a clinic willing to do 100 hairs but you will need to call around an inquire. 

Yes, less than 100 grafts is possible for an eyebrow transplant. The number of grafts will depend on the cosmetic outcome you desire.

You should be able to find a surgeon who will do small session for you if that's all you need. Your price per graft will likely by closer to $10-12 a graft because of the fixed costs and time associated with the procedure.

Alot of doctors will do small sessions. Helping patients enhance their appearance and improve the way they feel about themselves (whether 10 grafts of 5000) is our job!

The issue is the cost of set-up for the surgical team and the operating room. When a small procedure is done, such as what you are talking about, I often reduce my fee

yes, less than 100 hair grafts are possible for the eyebrow. It all depends on the number of grafts needed to give you the cosmetic outcome you are seeking. Therefore if you do not want to thicken eyebrow let's grafts can be placed. You need to remember that the graphs come from the back of the scalp and will grow longer than your own eyebrow hairs.therefore you will need to trim the eyebrows more often than you might be used to. Best wishes.
