Ever since fifth grade, when Mom took you to the hairdresser for a “little trim” and you walked out bawling, you’ve been a bit skittish about dramatic hair changes.

On the other hand, it’s been years since that fiasco; the scars on your psyche have to heal sometime. So take a deep breath, swallow hard, march yourself over to Shag, and sign up for their dramatic new asymmetrical shag cut.

You’ll immediately be reassured by the trappings of the chic salon — high ceilings, hardwood floors, and a reception area that’s more club lounge than waiting room. The hip but friendly stylists  further boost your confidence. And, of course, there’s the  haircut itself. Owner Sandy Poirier’s inspired coif is a softer shag: Relaxed, modified, and updated for summer, it’ll have you looking a little like an early Jane Fonda, but with minimal maintenance and prep.

You leave lighter and freer than you’ve felt in years.

And by years, we mean all of those since the carefree, pretrauma days.

Shag, 840 Summer Street, at East 1st Street (617-268-2500 or shagboston.com).
