Naturtint Permanent Hair Color 4N Natural Chestnut Brown 2-Pack

Naturtint permanent hair color: a gentler formula built with real botanicals

Shade 4N Natural Chestnut Brown blends organic corn and oat protein extracts with meadowfoam seed oil. These help protect strands during processing instead of stripping them.

Organic sunflower extract adds a layer of protection against sun and pollution exposure. For over 20 years, NATURTINT has worked to reduce harsh chemicals in permanent dye without losing depth of tone.

What's in the box

• 2 x colorant tubes and 2 x developers, for two full applications
• 2 x conditioning aftercare treatments to seal in tone and add shine
• Full application instructions

This 2-Pack of 165 ml kits suits shoppers who dye regularly at home. Keep one on hand for root touch-ups, or share the second kit with someone who wears the same shade.

How to use

1. Do a patch test at least 48 hours before every application, even if you've used this shade before.
2. Mix the colorant and developer, following the instructions inside the box.
3. Apply evenly to dry, unwashed strands. Leave on for the developing time stated on the pack.
4. Rinse thoroughly. Use the included aftercare treatment to help lock in tone and shine.

Certifications and standards

This formula is USDA BioPreferred Certified and ISO 16128 compliant, standards that verify the proportion of naturally derived ingredients in the mix. NATURTINT states the formula is up to 90% naturally derived.

The line is also vegan-friendly and not tested on animals, so it suits shoppers who want a more considered choice.

Who it's for

This 2-Pack suits anyone who dyes their own hair regularly rather than visiting a salon each time. Thicker or longer hair often needs a full box per application, so the second kit means you're covered without an extra shopping trip.

It also works well for two people who wear a similar shade, or for keeping a spare on hand between touch-ups.

Storage

Store both kits in a cool, dry place away from sunlight until ready to use. Once mixed, use the colorant and developer right away.

Safety information

Like most permanent dyes, this formula contains p-Phenylenediamine (PPD), an ingredient that can trigger allergic reactions in some people. Always run a patch test before your first use, even if you've used this shade before.

Stop immediately if you notice itching, redness, or swelling. Avoid use if you have a known dye sensitivity or a scalp condition. If you're unsure, check with a doctor first.
