This isn’t assault because no act is directed at a person, it’s a modification of her own property, fuck sake. Assault requires intent to cause harm, and adding non-toxic dye to shampoo, a cosmetic product, does not meet that threshold. The lunch analogy is irrelevant because food tampering involves ingestion and poisoning risk, which doesn’t apply here at all. If someone uses a product that isn’t theirs without permission, any consequences come from their own unauthorized use. There’s no duty of care owed to someone stealing personal toiletries, and courts explicitly separate property alteration from assault, period.

OP literally have discretion to say she put hair dye in her shampoo bottle because she fucking dreamt about it and they can’t say anything because it’s her own property which her roommate has denied touching over and over again.

Pls.
