This at‑home color kit offers a rich, natural darkest brown shade designed for full coverage on stubborn grays, root touch‑ups, or all‑over refreshes.

How well does this shade cover stubborn gray hair?

The 4.5NNN Knockout Collection shade is created specifically for difficult grays, using extra pigment strength for maximum coverage. Expect uniform color from roots to ends when application instructions are followed and processing times observed.

• Formulated for 100% gray coverage, even on resistant strands
• Extra pigment concentration in the Knockout shade
• Works for both roots and all‑over color refreshes

What makes the Smart 8‑Free formula different?

Smart 8‑Free means the permanent color avoids eight commonly criticized ingredients, reducing exposure to harsh chemicals found in many box dyes. The kit still provides reliable permanent color performance while aiming for a gentler experience on scalp and hair.

• Free of ammonia, parabens, resorcinol, PPD, phthalates, gluten, SLS, titanium dioxide
• Dermatologist‑tested and cruelty‑free with Leaping Bunny certification
• Designed for long‑lasting color without overly drying the hair

Will this kit keep my hair feeling healthy after coloring?

The formula includes nourishing additives—keratin for strengthening, argan oil for shine and softness, and ginseng root extract for a conditioned finish. These ingredients help minimize the dry, brittle feel that some permanent dyes can leave behind.

• Keratin helps support hair strength and manageability
• Argan oil adds smoothness and visible shine
• Ginseng root extract contributes to a conditioned texture

What comes in the kit and how often should I recolor?

The Madison Reed Radiant kit includes Radiant Cream Color, Conditioning Color Activator, disposable gloves, a plastic cap, barrier cream, and a step‑by‑step instruction booklet. Typical reapplication intervals are every 4–6 weeks depending on growth and desired coverage.

• Complete at‑home kit with tools and clear instructions
• Subscribe & Save available for scheduled deliveries
• Most customers recolor every 4–6 weeks to maintain coverage

Who is this for: This kit is ideal for people with mostly gray or stubborn gray regrowth who want a salon‑quality darkest brown result at home—especially those who prefer formulas without common harsh additives. It's also a strong choice for anyone seeking a conditioning approach to permanent color, and for users wanting the convenience of a complete, dermatologist‑tested kit.
