IGK Permanent Hair Color Kit 4N Original Brown - Salon Results

In this review of the IGK Permanent Hair Color Kit in 4N Original Brown, the bottom line is simple: it is aimed at someone who wants a rich, salon-style dark brown at home with added hair benefits. The reviewer found the formula easy to apply and appreciated that it promises 100% gray coverage while also delivering noticeable shine and softness. This kit is best for clients who prioritize a natural, dimensional brown and want color that conditions hair rather than leaving it dry.

Key Features

• Salon-developed formula: A colorist-developed recipe that aims to give professional-looking, dimensional brown without a steep learning curve.
• 100% gray coverage claim: Formulated to cover gray hair completely so users seeking uniform color can expect thorough coverage when used as directed.
• Ammonia free: The gentler formulation reduces harsh odor and can be less irritating for sensitive scalps while still depositing lasting color.
• Strengthen and shine: Clinically proven ingredients leave hair feeling stronger, shinier, and softer after coloring, according to the brand.
• Easy application: The kit is designed for at-home use and is reported by users to be straightforward to apply with predictable results.

Who It's For

This product is for users who want a true dark chocolate brown with salon-style dimension from an at-home permanent kit. It suits people with natural or previously colored hair looking to refresh their shade, improve hair softness, and address gray strands.

Those who rely on long-term color retention or need dramatic color shifts from very light to dark should consider professional salon services instead, and anyone with very porous or heavily highlighted hair should patch-test since individual fade and gray coverage results vary.

Pros & Cons

Pros

• Produces a luxurious dark brown shade with noticeable shine and softness reported by reviewers.

• Easy to use at home with a colorist-developed formulation for dimensional results.

Cons

• Gray coverage feedback is generally positive but not unanimous, so very stubborn grays may require repeat applications.
