L’Oréal Paris New & Improved Excellence Cool Creme permanent hair dye 4.11 Ultra Ash Brown

Loreal Paris New Improved Excellence Cool Creme Permanent Hair Dye 4 11 Ultra Ash Brown is a permanent hair colour cream from France that delivers cool-toned brown coverage with conditioning care — designed for anyone wanting a salon-quality ash brown result without the brassiness that often develops under strong sunlight and humidity. The cool creme formula helps counteract the warm undertones that Bangladesh's climate can bring out in coloured hair, while the built-in conditioning agents work to protect strands during the colouring process.

What makes Loreal Paris New Improved Excellence Cool Creme Permanent Hair Dye 4 11 Ultra Ash Brown different

This permanent hair dye uses an oxidative colour system combining ammonia, hydrogen peroxide, and direct dyes to penetrate the hair shaft and deposit lasting colour. The cool ash brown tone sits at level 4 with an 11 ash intensity, meaning it provides a medium-dark base with strong cool undertones to neutralise unwanted warmth. What sets this formula apart is the conditioning cream base that coats each strand during colour development, helping to minimise the typical dryness associated with permanent dyes. The cool pigment blend works to maintain the ash tone longer, which is particularly valuable in climates where UV exposure and humidity can accelerate colour fading and brassiness.

Best for

• Unprocessed or previously coloured hair wanting a cool ash brown result
• Those dealing with unwanted warm or brassy tones in their current colour
• Normal to oily hair types that want permanent coverage without heavy residue
• Chemically-treated hair needing a conditioning colour formula
• Covering grey hair up to 100% for a natural-looking ash brown blend
• Anyone wanting salon-quality permanent colour at home

A patch test behind the ear is essential 48 hours before full application, especially for those with sensitive scalps or history of allergic reactions to hair colour.

How to apply Loreal Paris New Improved Excellence Cool Creme Permanent Hair Dye 4 11 Ultra Ash Brown

1. Mix one part developer (included) with one part colour cream in the provided bowl until smooth
2. Apply immediately to dry, unwashed hair starting at the roots and working through to ends
3. Leave on for 35-45 minutes depending on desired intensity and hair condition
4. Rinse thoroughly with lukewarm water until water runs clear, then shampoo and condition
5. Protect your colour investment with UV-protectant hair products when styling outdoors

What to expect over time

Permanent colour means the result grows out rather than washing out, with the cool ash tone typically lasting 4-6 weeks before root touch-ups become necessary. The conditioning elements help hair feel softer immediately after rinsing, though regular deep conditioning treatments support long-term hair health. Like all permanent dyes, the colour may appear slightly darker in the first few days before settling into its true shade. Consistent use of colour-protect shampoo and conditioner helps maintain the ash tone against Bangladesh's challenging humidity and UV conditions. Results depend on your starting hair colour and condition, with lighter bases showing more dramatic transformation.
