cosmpro Dark Brown Hair Dye Shampoo 3-in-1 16.9 fl oz — Semi-Permanent Gray Coverage, Conditioning Formula

Cosmpro Dark Brown Natural Hair Dye Shampoo is a 3-in-1 semi-permanent color shampoo that conceals gray hairs while cleansing and conditioning for a refreshed, natural-looking dark brown tone.

This 16.9 fl oz (500 ml) bottle from Cosmpro combines gentle cleansing with color-depositing pigments and conditioning agents so you can refresh your natural dark brown shade at home without mixing kits or harsh treatments. Formulated for unisex use and designed to be simple to apply, the shampoo fits into a regular shower routine: apply to damp hair, work into a lather, wait 20–25 minutes, then rinse. The formula uses natural-derived ingredients where possible to soften and smooth strands while reducing the visual appearance of gray hairs.

How quickly will I see coverage of gray hair?

Most users notice a visible reduction in gray within a single application, especially on lightly gray or recently grown grays. Heavier or long-standing gray may need a few repeats to blend fully. Because this is a semi-permanent deposit, color gradually fades over several washes rather than providing lifelong coverage.

• Visible results often after one use on light grays
• Repeat applications over a week give deeper blending
• Color fades naturally over multiple washes
• Gentle formula avoids harsh chemical processing

Is the application process easy for home use?

Yes — the shampoo is made for straightforward at-home use without special tools. You only need gloves, damp hair, and 20–25 minutes of processing time while it lathers. No pre-mixing, brushes, or timing boards are required, making it a low-effort way to refresh color between salon visits.

• Apply to damp hair and create a lather for even pigment distribution
• Leave on for 20–25 minutes for optimal color deposit
• Rinse thoroughly and style as usual
• Suitable for weekend or evening touch-ups

What additional hair benefits does this shampoo provide?

Beyond color deposition, the formulation includes conditioning agents to help improve combability and surface smoothness. The product is positioned to cleanse while adding pigment and moisture, so hair looks refreshed and feels softer immediately after use. It’s not a permanent dye, so it avoids intensive oxidative processing.

• Combines cleanser, color-deposit, and conditioner in one bottle
• Leaves hair smoother and easier to manage
• Reduces visual contrast between gray and natural color
• Designed to be gentle compared with permanent dyes

How long will a 500 ml bottle last and how often should I use it?

Longevity depends on hair length and frequency. For short to medium hair, a 500 ml bottle typically lasts several weeks to a few months when used periodically for touch-ups. For daily maintenance or long hair, expect shorter lifespan; adjust usage to how quickly pigment fades and how much gray coverage you want.

• 500 ml (16.9 fl oz) size suits repeated touch-ups
• Short hair: longer bottle life; long hair: more frequent replenishment
• Use frequency: single-use coverage or repeated weekly applications
• Monitor fade and reapply as needed for consistent tone
