If the crown of your head is kind of square rather than round, layering on top is an option not to make your head look too big.
My client who has very thick unruly hair with flat back of the head and crown of his head squared, have been struggled finding the way to get a haircut that he likes until we first tried short sides long top hairstyle.
We decided to go as short as possible at the sides and back to create rounded silhouette at the crown by tapering up to the crown area.
We are trimming the top and texturize so that he can be refreshed with cutting the length and he will be able to play with the length on top and style his unruly hair nice and easy as he wishes.
By shortening the sides up to where about the temple, his head will stay look small until it gets long.
His hair on top is layered and texturized.
Balance of the weight is great after top has thinned and texturized especially like him wants the style subtle.
This is a slight change but makes difference.
Length is even and all the baby hairs are removed.
