This sleek, long jet black cut epitomizes minimalism with its flat volume and straight texture, perfectly complementing oval faces. The ultra-smooth strands create a mirror-like effect, emphasizing hair health and depth of color. This style suits formal occasions and those who prefer a refined, polished presence. Heat styling tools are essential to maintain the razor-sharp edges and sleekness.

Stylist's Tip

Use a flat iron and a heat protectant spray to achieve that impeccable sleekness and prevent damage.
