Farndu Black Hair Dye Shampoo — 3-in-1 Gray Coverage Shampoo, Ammonia-Free Conditioning

Farndu Black Hair Dye Shampoo is a 3-in-1 herbal color shampoo that quickly covers gray hair while cleansing and conditioning in one step.

Designed for people who want natural-looking black color without salon trips, this product blends botanical oils and plant extracts into an ammonia-free formula. It aims to cover gray hairs in as little as 10–15 minutes, leaving hair softer and more manageable. The shampoo doubles as a cleanser and conditioner, so you can color and care for hair during the same wash.

How quickly will Farndu cover my gray roots?

You can expect visible gray coverage after a single 10–15 minute application, though results vary by hair texture and the amount of gray. For full, even coverage, follow the instructions and repeat as needed across sessions.

• Application time: approximately 10–15 minutes per wash
• First-use visibility: noticeable coverage after one session for most users
• Maintenance: touch up with repeat washes to maintain depth

Will this shampoo damage or dry out my hair?

Farndu's formula is free from ammonia and parabens and includes nurturing ingredients like argan and olive oil to help retain moisture. It’s formulated to minimize harsh chemical damage and leave hair feeling softer than many permanent dyes.

• Herbal active ingredients help lock in moisture
• Argan and olive oils provide conditioning benefits
• No ammonia or strong chemical smell

How do I use this 3-in-1 black hair dye shampoo at home?

No bowl or brush is required — the product works like a regular shampoo. Wet hair, lather the product through the gray areas, leave it for the recommended 10–15 minutes, then rinse thoroughly for colored, conditioned hair.

• Use on damp hair as you would a normal shampoo
• Massage evenly into gray-prone areas and wait 10–15 minutes
• Rinse fully and style as usual; repeat for maintenance

How long does the color last and how many uses will one bottle provide?

Color longevity depends on hair-wash frequency and hair porosity. The manufacturer estimates the bottle provides approximately ten applications, making it a cost-effective alternative to frequent salon coloring.

• Estimated uses: around 10 applications per bottle
• Longevity depends on individual hair care routines
• Periodic reapplication keeps color fresh between treatments

Who is this for: Farndu Black Hair Dye Shampoo is suitable for adults of any gender seeking an easy at-home method to reduce or hide gray hairs while cleansing and conditioning their hair. It’s ideal for those who prefer ammonia-free, plant-enriched formulas and want a quicker, lower-cost routine than salon coloring. If you have sensitive skin, perform a patch test before first use and consult product guidance for allergy questions.
