When you use a girl's bathroom

Here's a lighthearted and funny description in English for your idea:

"Once upon a time, there was a guy who thought he was just getting clean, but little did he know... as he stepped into the bath, the soap had other plans! Scrub after scrub, layer by layer, he started to see a whole new side of himself. His skin wasn't just clean – it was transformed! He looked in the mirror, shocked, like he’d just unlocked a hidden superpower. Turns out, some baths don’t just wash you... they change you! Next time, he might read the label before jumping in!"
