Naturtint Permanent Hair Color 4N Natural Chestnut — Ammonia-Free, Vegan 1-Pack with Up to 100% Gray Coverage

Naturtint 4N Natural Chestnut is an ammonia-free permanent hair dye that delivers a rich chestnut tone with up to 100% gray coverage while conditioning hair with plant-based ingredients.

Designed for at-home use, this permanent color from Naturtint combines botanical actives and gentle chemistry to tint hair evenly without ammonia, parabens or heavy metals. The formula is USDA BioPreferred certified and ISO 16128 compliant, offering a cruelty-free, vegan option for those who want lasting, salon-style color with a softer scent and nourishing feel. Packaging may vary, but each single-pack contains everything needed for an easy application.

How natural-looking is the color and how long will it last?

You can expect a deep, natural chestnut shade that blends gray and natural color for a uniform finish. As a permanent dye, it penetrates the hair shaft for multi-week longevity; results will gradually soften with normal washing and sun exposure.

• Permanent color formulation for longer-lasting results
• Designed to deliver even tone and shine across mixed hairs
• Color retention depends on hair porosity and aftercare routine

Is this safe for sensitive scalps or damaged hair?

While Naturtint eliminates ammonia and other harsh ingredients, any permanent color can irritate sensitive skin. The formula includes plant-based conditioners to help nourish hair during coloring, but perform a patch test 48 hours before full application.

• No ammonia, no parabens, no heavy metals — gentler chemistry
• Infused with botanical ingredients to add moisture and manageability
• Recommended patch test to rule out allergic reactions

How easy is the application for an at-home color refresh?

The kit is designed for straightforward, mess-minimizing use so you can achieve professional-looking results at home. Clear instructions guide you through mixing and timing; using gloves and an application brush helps ensure even coverage, especially for root touch-ups.

• Single-pack contains developer and colorant for one application
• Simple mixing steps and timing directions included
• Suitable for both full-head coloring and root maintenance

What styling and aftercare will preserve color and shine?

To prolong the chestnut tone, use color-safe, sulfate-free shampoos and limit high-heat styling. Conditioning treatments and UV-protective products help maintain vibrancy and reduce fading from sun and chlorine exposure.

• Wash with gentle, color-protecting cleansers and lukewarm water
• Apply regular conditioning masks to replenish moisture
• Minimize frequent heat styling and use heat protectant sprays

Who this is for: Naturtint 4N Natural Chestnut suits anyone seeking a warm, classic chestnut shade without ammonia or animal-derived ingredients. It’s a good choice for people wanting comprehensive gray coverage, a more plant-forward ingredient list, and long-lasting color at home. If you have a known sensitivity to hair color ingredients, perform a patch test before use or consult a stylist.

• No ammonia, no parabens, no heavy metals
