How should I manage eyebrow and eyelash loss?

I've been worried about scalp hair loss lately, and it seems my eyebrows and eyelashes are falling out too, as if I'm experiencing hair loss. My eyebrows are getting thinner, and as my eyelashes fall out, they get into my eyes, so I have to pull them out with a cotton swab.

How should I manage hair loss in my eyebrows or eyelashes? Please recommend effective methods for hair loss management, such as where to receive professional care and what home care methods are available.
