10 days post-op. Looking for hair concealer/fibre recommendations. (Photos)

It is best to ask your surgeon about post operative care as each doctor has their unique regimen.   Toppik and Dermatch are widely used concealers. 

If you still have 19 days to go, I would hold off and just follow your routine follow up instructions.  By 19 days from now you should look and feel a whole lot better about yourself.  If you still need some concealer at that time, you can try something like Toppik fibers.  

I would say that you will be fine to use any concealer product after 19 days without causing any harm to the grafts. The most common is the Toppik fibers. Revivogen also have a line of this product that works very well. The link that I have attached also has some great information

The most popular concealer is the powdered Toppik which seems to be use by many of our patients
