Suggest Treatment For Eye Injury In A Child

Hello Doctor....My 1.8 years son fell from my arms onto the road and the fall took off a portion of his right eyebrow (40%). The skin got peeled off(along with that portion of his eyebrow) after washing with an anti-septic. Now, my worry is will his eyebrow grow back after his wound heals and his skin re-grows. I m totally worried..Please advise.
