One 'N Only Fast 10 Permanent Hair Color Kit - 4N Medium Brown with Argan Oil

Fast, at-home color with professional results

One 'N Only Fast 10 is a 10-minute permanent color kit designed to deliver full gray coverage and a vibrant, even tone. It supports full color applications or quick root refreshes, offering flexibility for busy schedules, weekend makeovers, or a last-minute update before events.

What makes this kit stand out is how it balances pigment with moisture. The formula blends argan oil, vegetable squalene, and Keraveg-18—a keratin-inspired blend that aims to support hair integrity while color is depositing pigment.

Nourishment and strength as you color

As the color takes, the nourishing trio works to support the hair’s surface. Argan oil softens dry strands, while Keraveg-18 works with the pigments to minimize dulling and maintain a smoother feel after washing.

• Argan oil nourishes and conditions during color
• Keraveg-18 strengthens hair along with pigment deposition
• Vegan, dermatologically tested, cruelty-free, and packaged with care

Clean beauty with a mindful footprint

The product line emphasizes clean, responsible beauty. The formula is vegan and tested for sensitive skin, and the packaging uses sustainable materials to reduce impact without compromising performance. You can color with confidence, knowing standards were considered.

What you get and how to use

• Shade: 4N Medium Brown for natural depth and balanced tones
• Color cream and developer for a reliable, even deposit
• Shampoo, conditioner, and argan oil post-color treatment for shine

How to apply in 10 minutes

1. Mix color and developer according to the included instructions
2. Apply to gray areas or roots, and process for exactly 10 minutes
3. Rinse well, then follow with shampoo, conditioner, and argan oil treatment

In real-life use, you can reach for this kit for a quick root refresh between salon visits, or to achieve a natural, even tone for a full color update. The result is a glossy finish and a smooth feel that stays comfortable through daily wear, with shine that catches the light as you move.
