Suspicious hair

I was brushing my hair and looking at the hairs in my hair brush and I found a piece that doesn’t look like mine, the hair on the left is the other woman I suspect and the hair on the right is mine what do you think is he cheating on me and if so why is she using my hair brush. I never had suspicions until I found this hair will get it DNA tested

Edit- someone mentioned she uses my toilet paper too. Very good point, didnt it think of that. I will be counting each square before and after I leave my house. I will also send the remaining roll for finger print testing as well. My rolls have been looking much smaller now that I think of it.

Also someone mentioned my douches- my massive douche collection is locked up those haven’t been touched
