Blonde girls I have found
Hide their roots when they go to town
No maybe
They're not nat'ral blondes

I know that some would dye
To conceal the proof
Their hairdresser knows
The whole sad truth
If they've got some smarts
You know they're not nat'ral blondes

If their flaxen head
Is filled with air
Then they might not be phony
So of course that means
It still all depends
The roots are still the key

Here is the main way
To tell if they're fake
They're dizzy 24 hours a day
And got no dark roots
You know they're a nat'ral blonde

Dumb'a, dumb'a, dumb'a, dumb'a, dumb, dumb
Oh, dense, dense, dense
Dumb'a, dumb'a, dumb'a, dumb'a, dumb, dumb
Oh, the roots are still the key

Here is the main way
To prove I'm no fake
I'm dizzy 24 hours a day
And got no dark roots
You know I'm a nat'ral blonde

Dumb'a, dumb'a, dumb'a, dumb'a, dumb, dumb
Oh, dense, dense, dense
Dumb'a, dumb'a, dumb'a, dumb'a, dumb, dumb
Oh, dense, dense, dense

The key
Dumb'a, dumb'a, dumb'a, dumb'a, dumb, dumb
To the nat'ral blonde
Dense, dense, dense

That's me
Dumb'a, dumb'a, dumb'a, dumb'a, dumb, dumb
I'm a nat'ral blonde
Dense, dense, dense
