Does eyebrow hair grow back after being scraped off?

I am sorry to hear of your eyebrow trauma. In many cases, the eyebrow hair will regrow; however, there are unfortunate cases where the eyebrow hair does not grow back. Give it about 6 months to see what comes back. If you have gaps or if you do not have regrowth, there is a solution. In the modern era of follicular unit hair transplantation, single hairs can be placed to fill in any gaps in your eyebrows. Best of luck with your recovery.

Eyebrows will usully grow after partial thickness abrasions.  The chances are unpredictable.  Topical agents may hasten regrowth.Please use this information when consulting in person with an experienced Board Certified Plastic Surgeon prior to making treatment decisions.

This is very unpredictable. It may take up to 6 months for regrowth to occur. Sometimes there will be no regrowth or gaps in the brow. 

sometimes the eyebrow hair regrows and if it does, it will take about 8 months for the hair to cycle. Sometimes it does not regrow and transplants become the only options for replacing it. 

If the follicles are damaged during your incident then the hair will not grow back, but if they are not damaged they will grow again.myou need to wait a few months to see what happens.  If they don't grow back, eye. Brow hair restoration is very successful.
