Welcome to HealthcareMagic forum,
Cindy,few of your symptoms goes towards a conditions called alopecia areata
.In this patient looses hair in small circular patches (even from eyebrows) and is associated with stress

In allergic condition if you have applied some thing which you are allergic to,then it can cause a irritant reaction where you can lose hair.
