OneLength

Onelength is a term most commonly used in hairstyling to describe a haircut where all hair is cut to the same length, creating a blunt, uniform edge with minimal or no layering. The phrase is often written as one-length or one length, and it can refer to both short and long styles.

In practice, a one-length cut aims for consistent weight and a clean silhouette, making it distinct from layered or graduated cuts that vary in length along the head. It is frequently associated with blunt bobs and straight, smooth-looking hair, though it can be adapted to longer looks. The technique emphasizes precise cutting, typically with blunt-edged scissors to produce a sharp endpoint. Hair texture and growth patterns influence the result, and very curly or highly textured hair may require texturizing or alternative styling to achieve a similarly even line.

Maintenance for a one-length cut emphasizes regular trims to preserve the even length and edge, typically every four to eight weeks depending on growth and desired shape. Styling considerations may include smoothing products, blow-drying, and flat ironing to enhance the crisp line.

Other uses: The term is also adopted as a brand name or product line in cosmetics, haircare, or fashion contexts, sometimes stylized as OneLength or onelength. In these cases, it functions as branding rather than a technical haircut specification.
