Type of Color: This is a permanent hair color that comes in a unique powder form. It is activated by adding room-temperature water, rather than a developer.

100% Gray Coverage: A primary selling point of Bigen is its ability to provide long-lasting and effective coverage for gray hair, even stubborn grays.

Ammonia-Free: The formula is free of ammonia and does not require hydrogen peroxide, which makes it a gentler option for the hair. It doesn't lighten the hair; it only deposits color. This "deposit-only" action results in less damage to the hair.

Long-Lasting: The color is designed to be durable and provide a rich, natural-looking hue that lasts.

Simple to Use: The process involves mixing the powder with water to create a paste, applying it to dry hair, and letting it develop for a specified time (typically 20-30 minutes for non-chemically treated hair).
