Granted, this is a little out of date, but there's an image of George Harrison's first passport widely available on the internet:

In the second photograph, his hair is completely covering his forehead. As you may know, he did visit the US along with the other Beatles, at a time when they all had similar hair styles:

It's pretty clear that standards may have changed somewhat in the last 52 years, but I expect that if your hair covers your forehead naturally, your photograph will not be a problem when you present yourself for immigration inspection.

I'm not sure if you need a US visa or not - most EU nationals do not require one for tourism, however for reference I am using the photo guidelines for US visas which don't state that your forehead has to be visible:
If your country has issued your passport photo - and the passport meets all other requirements (biometric/digital, etc.) then you should have no issues at the border.
Of course, this assumes you look like your picture and there is no significant material change in your appearance (see "taken within the last 6 months to reflect your current appearance")
I have used the same photo - which showed me with a large head of hair and some seriously big aviator specs - for applying to the US. Upon arrival, I had a shaved head and no glasses (was wearing contacts).
I was let in without issues; even though - by my own admission - I looked nothing like my passport photo.
