The Revlon ColorSilk Hair Color Shampoo Sachet in 20 Brown Black (often referred to as B.Black) is a quick-action, single-use coloring solution. It is designed for those who want the depth of black hair but with a softer, more natural-looking dark brown undertone. This sachet format is a staple in Pakistan for individuals looking for affordable, salon-quality gray coverage that can be done at home in minutes.

Key Features & Benefits

Natural "Soft Black" Finish: Unlike Shade 10 (Jet Black), Shade 20 provides a very dark brown-black hue that looks more natural against warmer skin tones and prevents a "harsh" look.

Rapid 5-Minute Formula: Deposits rich pigment in just 5 to 10 minutes, making it much faster than traditional permanent cream colors.

Ammonia-Free & Gentle: Formulated to minimize hair damage and scalp irritation, ensuring the hair remains soft and manageable after use.

Infused with Botanicals: Often contains nourishing ingredients like Noni Fruit, Olive Oil, or Aloe Vera to add a healthy gloss and prevent the dryness typically associated with quick dyes.

Ease of Use: No mixing bowls or professional tools required. The shampoo-in application allows for even distribution using just your gloved hands.

100% Gray Coverage: Specifically engineered to grip onto resistant grays, providing a uniform color from root to tip.

Shade Comparison: 10 vs. 20

10 Black: A true, deep Jet Black with cool/blue undertones.

20 Brown Black: A "Soft Black." It has a warm, dark chocolate/brown base that looks less intense and more like naturally very dark hair.

How to Apply

Preparation: Wear gloves to avoid staining your hands and nails.

Application: Apply the contents of the sachet to damp hair. Massage it in thoroughly, ensuring you cover the roots and temples where grays are most prominent.

Timing: Leave it on for 5–10 minutes. For very stubborn gray hair, you can leave it for the full 10 minutes.

Rinsing: Rinse with lukewarm water until it runs completely clear. Since it is a shampoo-based formula, you do not need to wash with regular shampoo afterward.
