L'Oreal Paris Magic Root Touch-Up Kit — 4A Dark Ash Brown (2 Count), 10-Minute Permanent Gray Coverage with Precision Brush

L'Oreal Paris Magic Root Permanent Hair Color Kit is a ready-to-apply root touch-up that covers 100% of gray regrowth in just 10 minutes using a low-ammonia permanent formula and a precision brush applicator.

When you need a fast, dependable solution between salon visits, this targeted root kit simplifies the process: no separate mixing bowls, a soft precision brush for accurate placement at the hairline and part, and a conditioning color gel designed to blend with existing salon color. Each kit is intended for spot application to roots and regrowth, delivering salon-like permanence that lasts until new hair grows in—typically up to four weeks. The low-ammonia formula helps reduce odor and dryness while leaving hair manageable after rinsing.

How quickly will I see results with the Magic Root kit?

You’ll achieve full gray coverage in as little as 10 minutes from application to rinse, making it ideal for last-minute touch-ups before events. The permanent formula bonds to the root shaft for even coverage and blends into your surrounding hair for a natural finish.

• Process time: 10 minutes from application to rinse
• Coverage: Designed to cover 100% of gray regrowth
• Longevity: Color holds until new growth appears—up to about 4 weeks
• Finish: Blends with existing color for a seamless look

What makes the application easier than traditional box dyes?

The kit is preassembled for root touch-ups so you don’t need to mix product in a bowl. A soft precision brush applicator and a built-in conditioning developer bottle allow accurate, low-mess application at the hairline, part, and temples—areas where gray typically appears first.

• Ready-to-apply design eliminates separate mixing steps
• Precision brush targets roots, hairline, part, and temples
• Includes gloves and applicator tip for neat control
• Small, single-purpose kit size suited for targeted use

Is this gentle on hair and suitable for repeat use?

The low-ammonia formula contains an integrated conditioning agent that helps leave the treated area feeling smoother and less dry than traditional permanent dyes. It’s intended for periodic root touch-ups; follow the instructions and wait times between applications to maintain hair health.

• Low ammonia for reduced odor and gentler processing
• Built-in conditioner to soften and detangle after treatment
• Designed for repeat touch-ups when regrowth appears
• Compatible with L'Oreal Elvive color-protecting shampoo and conditioner for extended vibrancy

Which shade is 4A Dark Ash Brown best for matching?

Shade 4A Dark Ash Brown suits medium-to-dark brown base colors that need a cool, neutral ash tone at the roots. It blends well with professionally colored hair as well as most at-home brown shades, especially when root regrowth is under one inch.

• Designed to match dark brown or cool-toned brown bases
• Works well when root regrowth is less than one inch
• Available across a shade range from black to light blonde for broader matching
• Helps create a subtle, natural transition between dyed lengths and new growth

Who is this for: The L'Oreal Paris Magic Root Permanent Hair Color Kit is ideal for people who regularly maintain colored hair and need a fast, precise solution for gray roots—busy professionals, frequent travelers, or anyone who prefers quick at-home touch-ups over salon visits. It’s suitable for first-time touch-up users and experienced at-home dyers who want a repeatable, low-mess routine. Use this kit for targeted root coverage rather than full-head color; for full-color changes, choose a full-coverage hair dye product and follow professional guidance when needed.
