Just a few ideas. Helmet or not.

For Men:

1. Keep it short or shave it off.

2. Join a gym close to work. Shower and style there.

3. Get a job where no one cares.

For Women:

1. Style it really short or grow it really long. Cute "in between" styles and spiked doos are out unless...

2. Join a gym close to work and style there.

3. Don't look good in a crew cut? Grow it long, pull it into a pony tail. Helmet hair is impossible. For professionals, when you get to work, twist the pony tail into a bun and pin it up in on minute (with practice).

4. Get a job where no one cares.

HINT: If you are trying to land a rich law partner or doctor, get the cutest hair style possible, make the investment in a cheap car and pay for parking until the whale is landed. After the honeymoon see 1-4 above.
