Hairs grow in all directions after eyebrow transplant.

Hair direction is controlled directly by the surgeon who need to precisely angle and direct the hairs when making the recipient sites. 

I couldn't agree more with what was previously stated.  It is of utmost importance that the sites are made at the correct angles and the grafts are placed at the correct angles as well.  This is why you need to ensure that you are going to someone experienced in transplants and is comfortable with the amount of single grafts being used, as well as with the angle of placement.  Your best bet right now is to contact your doc and have them examine you.  An in person evaluation is necessary to determine a possible solution as you may need some minor tweaking.  Best of luck. 

Unfortunately it sounds like the practice you went to may not have placed the new hairs in the correct fashion.  Eyebrow restoration takes considerable skill, and graft placement with proper angles is crucial.  If it is really unacceptable you may need to consider laser hair removal and revision.  Best, Dr. rome

I have taught a course in hair transplant now for 9 years and teach on eyebrow hair transplant and will be giving this talk next week.  I always advocate to my students that it is the most difficult procedure to master and they should not even start thinking about doing it for at least many years after starting a hair practice.  Even though I make my recipient sites very flat and my staff work to make sure every hair curl (the natural curvature of the graft) aims downward, my grafts can still be upward displaced even by a few degrees.  What I do is I have all my patients at a week to wear a gentle ACE wrap at night for a month and then I have them do this again for several weeks when the hairs start to grow in.  There is a chance that this technique can help you if you catch it early enough.  During the day you may also try mustache wax to control them.  If they really look bad, they should all be removed by plucking or electrolysis and the procedure redone.  Unfortunately, I have had to fix too many of these cases.

You should go back and see your surgeon and show him that you are unhappy with the growth direction of the eyebrows as the direction was contolled by the surgeon who placed them

Eyebrow hairs grow in different directions you move down the eyebrown.  Typically the hairs in the middle are more up and down, and then the direction tends to angle outward as you move across the brow towards the sides of the head.  The graft punctures need to be angled accordingly so that the hairs fall in a natural looking pattern.
Hair transplant, whether to the head, eyebrows, or other areas of the body, is a unique specialty.  It is incredibly important that the implanting provider be familiar with the natural angles of the hair so that they are implanted appropriately. I would schedule a consultation with a provider who is very familiar with this procedure and performs it often.  Best of luck!

This is why it is so important that hairs are planted at the correct angles during a hair transplant of any kind. You can try and use a hair gel or wax to groom the  eyebrows, but your best option may have to be a revision of some kind to fix those hairs that are sticking straight out instead of the angle of the natural flow.
