I picked this area, will my hair grow back?

There is a condition called Trichotillomania which is a good possible diagnosis. See a dermatologist who will look at it with a hand microscope called trichoscope and make the diagnosis for you.  If it is chronic picking that you did that caused it, it may not return.  You will know if you can stop picking it, give it 4-6 months and you will know if it is permanent of not.

People who have trichotillomania are not candidates for a hair transplant because they just will pick off the new hair, so many hair transplant surgeons don’t treat this condition surgically unless the underlying problem of picking is solved
