No, a silk press is not exclusive to black hair.
A silk press is a hair straightening technique that uses heat and a styling product to create a smooth, sleek finish. It is popular among people with textured hair, including black hair, but it can be used on any hair type.
While silk presses are often associated with black hair, they can be adapted to achieve different looks on various hair textures. For example, a silk press on straight hair can be used to enhance shine and manage frizz, while on wavy or curly hair, it can create a sleek, straightened style.
Ultimately, the suitability of a silk press depends on individual hair type, desired outcome, and personal preference.
