First... whatever un-natural (shampoos, conditioners, make up) anything that you might be applying to this area...stop using it completely. Some people have very noticeable reactions to any kind of chemicals and this may be one of those situations.
By not using them you can find out if this is the cause.
Second...I have been doing some more research recently and discover that cow colostrum (while used as a natural supplement to restore natural health and beauty) it can also be applied as a paste externally to heal skin and hair conditions.
A tablespoon of
cow colostrum powder mixed with a small amount of spring water to make a paste and applied to your hair line might work. (wash off after 30 minutes or so).
I would recommend doing this for a week or 2 to see if there is any noticeable difference.
Cow colostrum has been used by ancient Ayurveda practitioners for thousands of years and has had huge benefits in fighting disease, skin and other conditions.
I wish you the best.
