Do I say something?

My MIL cut my toddlers hair recently. She’s a professional hairdresser but does it only for family now. One of my LOs had a comb in hand and I took it away. I saw the comb was with lots of buildup 😬. I went to put it back on her set and saw the other stuff dirty, brushes with hair on it still!! I was grossed out. Didn’t say anything though. Aren’t they supposed to disinfect and clean that all up? Does it matter? Do I tell hubby do he can talk to her?

She will definitely offer to cut hair again.
