One of its main strengths is the simple application process; mixing the color and developer only takes a few minutes, and the included brush helps ensure an even distribution. The formulation, enriched with Biotin, Aloe, and Coconut Oil, promotes healthy facial hair, making it a more nourishing option compared to many traditional dyes.

It works well on various types of facial hair, including mustaches and goatees, making it versatile for different styles.

However, there are a few considerations to keep in mind. The need for a skin allergy test before use may pose an inconvenience for some. Additionally, the five-minute waiting period might feel a bit long if you’re in a hurry. While the product is designed to be straightforward, not all users will feel confident mixing and applying dye, especially if they are new to it.

However, there are some drawbacks to consider. The product is available only in black, which may not suit all hair colors, limiting its versatility. Additionally, while the temporary nature of the dye is appealing for those looking for a quick fix, it also means that it requires daily reapplication for those needing a long-term solution. Users with sensitive skin should also conduct a patch test to avoid potential irritation. This beard filler is best suited for men needing a quick, easy, and natural-looking way to enhance their facial hair for the day.

Additionally, it can be used with an airbrush for precise application, making it suitable for professional barbers. The absence of harmful ingredients like alcohol adds to its appeal, making it safe for skin application. However, it's important to note that the product requires an additional airbrush device for the best results, which could be a drawback for everyday users who may not have access to such tools.

The ease of application might be less straightforward without this equipment. Furthermore, while it provides a sharp and clean finish, its effectiveness in covering gray hair and improving thinning hair may vary based on individual needs and preferences. Users seeking a more versatile product might need to consider this aspect. The package is relatively small, containing 6 milliliters, which might need frequent repurchases for regular users.
