I am Asian and noticed a balding spot in my crown from a photo taken. Is this balding ? (photo)

In people with dark straight hair and light skin, the swirl on the crown may highlight a light scalp. To find out if this is balding, a doctor can look at it with a hand microscope and if there is miniaturization present in excess of 20% of the hairs in view, then you can consider this the early part of the balding process in the crown.  If not, it may just be the characteristics of your hair.
