Thanks for posting your query.
It is interesting that you had asked some specific question to answer.
Alopecias are basically divided into two. 1. scarring and 2. non scarring.
only non scarring are easy to treat. scarring are difficult to treat. scar is like an injury
on the body after a road traffic accident. Imagine if you develop a scar it is going to be difficult to treat.
There are many reasons for both entities. What you have mentioned is one of those reasons.
CCSA means it spreads from the center to periphery. The reason for this is not known but a disease called lichen planus
may be again instigating this change.
There are no specific treatment for this condition as i said scars
are difficult to show improvement.
Everyone gives the best in their experience.
If you still want to get rid of that only a plastic surgery
