BOJICA 3-in-1 Black Hair Dye Shampoo for Gray Hair — 16.9 fl oz, Instant Full Coverage & Conditioning

BOJICA 3-in-1 Black Hair Dye Shampoo is a ready-to-use, vegan black color shampoo that covers gray roots in 15–20 minutes and doubles as a conditioner for up to 3–4 weeks of color retention.

This easy, at-home hair color solution is formulated to restore a uniform jet-black tone without the bowls, brushes, or lengthy salon visits. Packaged in a 500 ml (16.9 fl oz) bottle, the formula is designed for use on dry hair and aims to combine coloring, cleansing, and conditioning in one step. Each bottle typically provides about ten applications depending on hair length and amount used.

How quickly will BOJICA cover my gray hair?

Most users see visible gray coverage in 15–20 minutes when applied to dry hair; for denser gray patches, allow 20–35 minutes for fuller saturation. Timing affects intensity: shorter times give subtle darkening; longer times produce deeper, more consistent coverage.

• Apply to dry hair only for best uptake.
• 15–20 minutes for general gray blending.
• 20–35 minutes for heavier or stubborn gray coverage.
• Rinse and shampoo gently after processing time.

What does "3-in-1" mean and how does it treat my hair?

"3-in-1" refers to combined coloring, cleansing, and conditioning functions in a single product. The formula deposits pigment while providing moisture and fortifying strands so hair looks smoother and less dry after coloring.

• Coloring: pigments lay down black tones to mask gray.
• Cleansing: works like a shampoo to remove surface buildup during application.
• Conditioning: leaves hair softer and easier to manage post-rinse.
• Vegan formula designed to avoid the harshness of traditional dyes.

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

The deposited black color keeps its appearance typically up to 3–4 weeks, depending on hair-washing frequency, sun exposure, and styling. A single 500 ml (16.9 fl oz) bottle generally covers about ten full applications for average hair length; short hair requires less product and more uses per bottle.

• Color persistence: approximately 3–4 weeks under normal conditions.
• Use estimate: about 10 applications per 500 ml bottle.
• Factors affecting longevity: shampoos used, heat styling, and sun exposure.
• Refresh as needed to maintain uniform color between applications.

What comes in the package and are there special precautions?

The kit arrives with the BOJICA 3-in-1 Black Hair Dye Shampoo, a disposable cape, gloves, and a protective hat to contain any drips and make application cleaner. A patch test on a small area of skin before the first full use is recommended to check for sensitivities.

• Included: 500 ml (16.9 fl oz) bottle, disposable cape, gloves, and hat.
• Application: no bowl or brush required—use like regular shampoo on dry hair.
• Safety: perform a skin sensitivity test prior to first use.
• Cleanup: designed to minimize staining when used as directed.
