Tom Cruise's Hair

In the image, Tom's hair is styled in a modified "Ivy League" cut, featuring an elongated fringe and longer lengths on top. This cut suits many men, particularly those with straight hair types and medium to fine textures.
To achieve this look, trim the perimeter of the hair as you would for a traditional men’s cut. Layer the sides and back to approximately 1 to 1-1/2 inches, gradually increasing the length to about 2 inches at the crown and 3 to 4 inches at the fringe. Texturize the hair using point cutting or a razor tool, as desired.

In the photo, the cut is styled with a side part and finished with a simple blow-dry. Apply leave-in conditioner and your preferred styling product to damp hair, then blow dry until mostly dry.
Use a small amount of styling wax between your fingers to slightly muss the hair and add definition to the style.
