Singer Katy Perry says she prefers men who take care of themselves which includes nails, teeth.

The `Dark Horse` hitmaker shared that she likes men with trimmed hair rather than completely waxed, reports femalefirst.co.uk.

"If your teeth and nails are good, you're a candidate. If you can't clean under your nails and you want to touch me, forget it. Personally, lesser the hair, the better. I like a trimmed man but not completely waxed. I'm not into that f***boy look,` Glamour magazine quoted Perry as saying.

The 30-year-old also shared that there is a certain fragrance which always takes her back to memories of her first boyfriend.

"If I meet a guy in the elevator who's wearing 'Acqua di Gio', I think of my first boyfriend. One of my favourite things about fragrance is the powerful memories associated with it,` Perry said.

"My signature scent now is, and always has been, a blend of vanillas. And I never spray it on my skin. I spritz and walk through--or levitate through. I like to spray it on my hair too. With 'Mad Potion', the two main ingredients are exotic vanilla and androgynous musk. It's definitely a sweeter perfume. I like to be edible. I want somebody to ... eat me,` she added.
