Question: Can pet allergies cause hair loss?


 FancyCats2 - Tue Jul 06, 2010 4:37 pm

My significant other is a 25 year-old female who is experiencing hair loss (alopecia) around her temples, her part, and generally thinning hair all over (strands fall out constantly). We live with two cats, and blood tests have shown her to be very allergic to the cats (about an 18% measurement). The question is, could the allergy to the cats be causing her to lose her hair? Thank you!

User avatar Hello,As far as I know there is no connection, as far as allergy goes by.Of couse there are certain zoophilic fungi which can infect hair in humans to cause hairloss.Tinea capitis still would have characterestic features of patchy hair loss with itching and scaling.This would not result in the thinning as in your post.
Here one would rather think of telogen effluvium which is a temorary hairloss related to stress and general weakness.Also iron deficiency,hypothyroidism,and androgenic alopecia need to be considered.
Best wishes.
