Any way to treat alopecia?

Depends. Causes include, but not limited to : vitamin deficiencies, poor diet, thyroid issues, anemia, hormonal imbalances/changes, medications, genetics, tension of hair (pulling back), damage from chemical treatments/dyes, obsessive pulling (trichotillomania) - the solution is find the cause, as each cuase has different treatment. Would talk to your physician and consider labwork.
