See more Review: Glad I made the switch from other dyes - I used to use herbal hair dyes, but once I found out Garnier no longer tests on animals I was happy to give this one ago. And I am in love! It is so gentle on my scalp, any other hair dyes I previously used would leave my scalp itchy. My hair also feels great afterwards, and not bone dry like after other dyes. I use the rose gold hair colour on top of my dyed ginger hair. This doesn't make a big colour difference, BUT it does give the colour much more vibrance and gives it a coppery sheen that I am in love with! There also doesn't seem to be any unnecessary plastic in the box, which I am fond of! The only thing to note is that the colour does take a while to develop, so it's worth just shaking the bottle a bit longer until the colour fully develops. Also I definitely need two boxes for longer hair! Review: will buy again. - lovely colour. ## Features - Please check PAO (Period After Opening) symbol which denotes the product expiry time, post opening the pack ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E4L5S44 | | ASIN | B00E4L5S44 | | Benefits | Hair Coloring | | Best Sellers Rank | 29,903 in Beauty ( See Top 100 in Beauty ) 407 in Permanent Hair Colour | | Brand Name | Garnier | | Colour | 4.0 Dark Brown | | Container Type | Tube | | Customer Reviews | 4.1 4.1 out of 5 stars (29,249) | | Customer reviews | 4.1 4.1 out of 5 stars (29,249) | | Delivery information | We cannot deliver certain products outside mainland UK ( Details ).

I used to use this colour religiously 4/5 years ago and decided I wanted to use it again. There was basically no colour at all in the dye, it was almost like it was all developer. Even when washing out there wasn’t any colour at all in the water. Very confusing and disappointed especially having used this colour so much in the past and loving it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/60687501-olia-permanent-colouring-and-bleaching-4-0-castano-scuro](https://www.desertcart.pt/products/60687501-olia-permanent-colouring-and-bleaching-4-0-castano-scuro) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-09*
