How quickly will I see results with this beard dye?

Color develops in about five minutes after application, offering an immediate change in the appearance of gray facial hair. Because the formula is a brush-in gel, it spreads evenly for consistent coverage across mustaches, beards, goatees and sideburns.

• Full gray coverage in 5 minutes for fast touch-ups
• Brush applicator targets coarse facial hair precisely
• Up to three applications per box for multiple uses
• Simple rinse-and-shampoo finish for quick cleanup

Will this product damage my facial hair or skin?

The formula is ammonia-free and includes conditioning ingredients such as keratin, biotin, aloe and coconut oil to help maintain hair texture and softness while coloring. However, as with any color product, perform the enclosed allergy test 48 hours before first use and follow safety instructions to reduce staining and irritation risk.

• Ammonia-free to avoid harsh chemical exposure
• Keratin and biotin help support hair strength during coloring
• Includes aloe and coconut oil for added conditioning
• Use provided gloves and patch test as directed

How do I choose and apply the right shade for my beard?

Select from the available shade range; if you’re unsure, pick the lighter shade first since you can always darken later. Mix the color base and developer, apply with the included brush for targeted precision, wait five minutes, then rinse and shampoo for best results.

• Medium-dark brown (M-40) matches natural darker tones without looking artificial
• Brush-in gel lets you target specific gray strands and edges
• Step-by-step instructions included for consistent outcomes
• Ideal for mustaches, beards, goatees, sideburns and touch-ups

How often should I reapply to keep a consistent look?

Frequency depends on how quickly your facial hair grows and how much gray returns; many users touch up every few weeks. Each box provides up to three applications, and the three-pack gives multiple cycles or one for each grooming station you use.

• Reapply when new gray hair becomes noticeable
• Each box covers up to three applications; pack of three extends coverage
• Great for periodic touch-ups without salon trips
• Follow package timing and safety recommendations for repeat use
