COSMTEK Chestnut Brown Color-Depositing Shampoo 16.9 oz — Sulfate & Ammonia Free, Argan Oil Conditioning

COSMTEK Chestnut Brown Hair Dye Shampoo is an easy-to-use, color-depositing shampoo that refreshes light brown tones and adds warm chestnut hues with conditioning oils.

If you want a quick way to add chestnut warmth without a multi-step salon process, this 16.9 oz color shampoo delivers gradual, buildable pigment while helping hair feel smoother. The formula is free of sulfates, ammonia, and preservatives, and includes argan oil, olive oil and turmeric to reduce frizz and maintain moisture during color-depositing. It’s designed for at-home use on natural or previously colored hair; results depend on your starting color and hair porosity.

How do I use this shampoo for best color results?

Apply to dry hair for the most noticeable deposit: lather, leave on 15–20 minutes, then rinse thoroughly. Repeating every few washes builds intensity; single-use gives a subtler tone. Always patch-test for allergies before contact with scalp.

• Use on dry hair for 15–20 minutes for best pigment uptake.
• Rinse thoroughly and follow with a conditioner as needed.
• Repeat applications over several washes to deepen color gradually.

Will this cover gray hair or fully change very dark bases?

This chestnut shade is formulated primarily to deposit color and enhance brown tones; it is not intended as a guaranteed gray coverage treatment. On light to medium brown bases it adds chestnut warmth; on very dark or resistant gray hair, results may be minimal and uneven.

• Best for enhancing or refreshing light–medium brown hair.
• Not designed as a reliable solution for complete gray coverage.
• Very dark hair may show only subtle change unless pre-lightened.

Does the formula protect hair from drying or frizz?

The shampoo contains argan oil and olive oil to help smooth hair cuticles and maintain softness while depositing color. Turmeric and conditioning agents help reduce frizz so hair looks conditioned after rinsing. It’s free of sulfates and ammonia, which helps prevent additional stripping of natural oils.

• Argan oil and olive oil add moisture and shine.
• Sulfate- and ammonia-free formula reduces aggressive stripping.
• Leaves hair smoother and more manageable compared with harsh dyes.

Is this safe and what precautions should I take?

Ingredients are disclosed and the formula avoids common harsh chemicals, but an allergy test is recommended before first use. Avoid contact with eyes, mouth, and open wounds; discontinue if irritation occurs. Follow the included directions for timing and frequency to minimize unexpected results.

• Perform a skin sensitivity patch test before full application.
• Keep away from eyes and mucous membranes and rinse if contact occurs.
• Follow usage instructions; individual results vary by hair type.

Who is this for: COSMTEK Chestnut Brown Hair Dye Shampoo suits people who want a convenient, conditioning way to add warm brown tone or refresh existing chestnut shades without peroxide or ammonia-based dyes. It’s ideal for those looking to maintain or enhance brown color between salon visits, users wanting gentler color-depositing options, and anyone seeking a low-effort at-home tint that improves manageability as it colors. If you need full gray coverage or dramatic lightening, consider alternative products made specifically for those needs.
