This long jet black hairstyle is sleek and straight with flat volume, creating a minimalist look that accentuates an oval face’s natural symmetry. Heat tools are necessary to achieve the mirror-like finish, making it a high-maintenance style perfect for formal occasions or a chic everyday aesthetic. Its simplicity is its strength.

Stylist's Tip

Finish with a shine-enhancing spray post flat-ironing to elevate the sleekness without weighing down the hair.
