My partner kept using my expensive hair products without asking, which drove me nuts! I told them to stop, but they just laughed it off and said, ‘It’s just shampoo, babe!’ So, I hatched a plan.

I bought a small, colorless hair dye that was a few shades darker than their natural color. I mixed just a tiny bit into my shampoo bottle. Not enough to be obvious, but enough to see some results over time. Every day, they washed their hair, and every day it got slightly darker.

After about a week, they finally noticed. They came to me in a panic, asking if I thought their hair looked different. I played dumb, saying, ‘Huh, weird. Maybe it’s the new shampoo you’re using?’

They freaked out, thinking they were losing their natural hair color and started frantically Googling ‘premature graying.’ Eventually, I fessed up, laughing so hard I nearly cried. Now, they always ask before touching my products. Petty? Maybe. Worth it? Absolutely.
