Just for Men Shampoo-In Hair Color — Real Black (H-55), 3-Pack, Ammonia-Free 5-Minute Gray Coverage with Keratin

Just For Men Shampoo-In Color (Real Black, H-55) is a five-minute, ammonia-free hair color that targets gray hairs to restore a natural, darker look and lasts until new gray grows in.

This three-pack of Just For Men Shampoo-In Color uses patented gray-targeting technology to darken only the gray hairs while preserving the natural variations of your original color. Enriched with keratin, olive oil and vitamin E, the formula aims to leave hair looking stronger and healthier without the harsh smell or damage associated with ammonia-based dyes. Designed for easy at-home use, the shampoo-in system mixes in an applicator bottle and works quickly for repeatable, professional-looking results.

How quickly will I see results and how long do they last?

Results appear in as little as five minutes after application and the color binds to gray hairs for durable coverage. The effect is permanent until the treated gray grows out, typically lasting up to about eight weeks depending on your hair growth cycle and washing routine.

• Visible color in approximately five minutes
• Lasts until new gray hair grows back (commonly up to 8 weeks)
• Can be reapplied for maintenance or heavier coverage
• Each box provides up to three applications for touch-ups or larger coverage

Will this product change my natural hair texture or cause damage?

The formula is ammonia-free and includes keratin, olive oil and vitamin E to help maintain hair strength and manageability. While any coloring process alters pigment, this product is designed to minimize harsh effects and preserve the feel and natural variation of your hair.

• Ammonia-free formula reduces aggressive chemical exposure
• Keratin helps support hair strength
• Olive oil and vitamin E add conditioning benefits
• Targets gray strands rather than overcoating all pigment

Application is simple: mix the color base in the provided applicator bottle, shake, apply evenly to dry hair, wait five minutes, then rinse. A skin allergy test 48 hours before first use is recommended, and gloves are included to prevent staining.
