Choosing a new hair colour can feel exciting and a little scary at the same time. With so many brands on the shelf, it is hard to know which one will deliver rich, even and long-lasting results. L’Oreal hair colour is one of the most trusted names in the world of hair dye, and for good reason.
The brand has spent over a century researching hair science, and its range covers everything from natural browns to bold fashion shades.
In this guide, you will learn about the main L’Oreal hair colour ranges, how to read shade numbers, how to pick the right tone for your skin, how to apply colour at home, and how to keep your hair healthy afterwards. Whether you want to cover grey, go lighter or try a vivid new look, this article will help you decide with confidence.
Why L’Oreal Hair Colour Is So Popular
L’Oreal Paris is one of the largest beauty companies in the world, and its hair colour products are sold in almost every country. People choose L’Oreal hair colour for several reasons.
First, the shade variety is huge. You can find hundreds of options, from deep black and chestnut brown to ash blonde, copper red and even pastel fashion tones. Second, the formulas are designed for strong colour payoff and good grey coverage.
Third, many ranges include conditioning ingredients and a post-colour care treatment in the box, which helps reduce dryness.
Another big advantage is accessibility. L’Oreal hair colour is available in pharmacies, supermarkets, beauty stores and online shops, usually at a fair price compared with salon visits. The instructions are clear, the kits include gloves and developer, and the results are generally predictable when you follow the steps properly. For beginners, that combination of reliability and ease makes L’Oreal an obvious first choice.

Popular L’Oreal Hair Colour Ranges
L’Oreal offers several product lines, and each one suits a different goal. Here are the most well-known ones.
Excellence Creme: This is the brand’s classic permanent colour, popular for its strong grey coverage. It uses a triple-care approach with a conditioner included, and it suits people who want reliable, long-lasting results.
Superior Preference: Known for rich, shiny, multi-dimensional colour, Preference is often chosen by people who care about glossy finish. It is a permanent colour with a wide selection of blondes, browns and reds.
Casting Creme Gloss: This is an ammonia-free formula that gives a gentle, shiny result with a pleasant scent. It is a popular pick for people with sensitive scalps or those who want a softer colouring experience.
Féria: Féria is the brand’s fashion-forward line, offering vibrant, high-shine and multi-faceted shades. It is perfect if you want a statement colour like deep burgundy, bright copper or cool metallic tones.
Colorista: Colorista is a range for bold, creative colour. It includes semi-permanent and temporary options, such as pastel and neon shades, which wash out over time and are ideal for experimenting.
Magic Retouch and root products: These sprays and quick-fix products cover grey roots between full colouring sessions.
L’Oreal Professionnel: For salon use, lines like Majirel and INOA are widely used by stylists who need precision and consistent results.
Understanding L’Oreal Hair Colour Shade Numbers
The shade numbers on a L’Oreal hair colour box are not random. They follow a system that tells you how light or dark the colour is and what tone it carries.
The first number shows the level of depth, usually from 1 to 10. Level 1 is black, levels 3 and 4 are dark to medium brown, level 5 and 6 are light brown to dark blonde, level 7 and 8 are medium to light blonde, and levels 9 and 10 are very light and platinum blondes.
The number after the dot or slash shows the tone or reflect. Common tone indicators include:
- Ash or cool tones: reduce unwanted warmth and brassiness
- Golden tones: add warmth and a sunny shine
- Copper tones: bring orange-red warmth
- Red and mahogany tones: deliver rich red or burgundy depth
- Natural tones: keep the colour close to a true, balanced shade
For example, a medium ash brown will look cooler and less warm than a medium golden brown, even if both are the same level. Understanding this system helps you avoid surprises and pick a shade that actually matches the colour you imagine.
How to Choose the Right L’Oreal Hair Colour for Your Skin Tone
The most flattering hair colour usually works with your skin undertone rather than against it. Undertones are generally described as warm, cool or neutral.
Warm undertones: If your skin has a golden, peachy or olive glow and gold jewellery suits you, warm shades like golden brown, honey blonde, copper and caramel often look beautiful.
Cool undertones: If your skin has pink, red or bluish hints and silver jewellery looks better on you, cool shades like ash brown, ash blonde, burgundy and cool black usually suit you best.
Neutral undertones: If you can wear both gold and silver, you have more freedom. Natural tones and balanced browns are very flattering, and you can experiment with both warm and cool options.
A simple rule is to stay within two shades of your natural colour if you are colouring for the first time. This gives a natural look and makes regrowth less obvious. If you want a dramatic change, consider testing a semi-permanent shade first, or visiting a stylist for advice.
Permanent vs Semi-Permanent vs Temporary Hair Colour
Before buying any L’Oreal hair colour, you should know what type fits your needs.
Permanent colour uses a developer and an alkaline agent to open the hair cuticle and deposit colour deep inside. It can lighten or darken hair and cover grey effectively. It does not wash out, but you will need to touch up regrowth every four to six weeks.
Demi or semi-permanent colour deposits colour without lifting natural pigment much. It fades gradually over several washes. It is a gentler option and works well for enhancing tone, adding gloss or blending a small amount of grey.
Temporary colour coats the surface of the hair and washes out in one or a few shampoos. It is best for parties, festivals or testing a bold shade without commitment.
If you have never coloured your hair, a semi-permanent option is a safe place to begin. If you want guaranteed grey coverage or a lighter result, permanent colour is the better choice.
Step-by-Step: How to Apply L’Oreal Hair Colour at Home
Applying hair colour at home is straightforward if you prepare well and follow the instructions carefully.
1. Do a patch test. At least 48 hours before colouring, apply a small amount of the mixed colour behind your ear or on your inner elbow. If you notice redness, itching or swelling, do not use the product.
2. Prepare your tools and space. Wear old clothes, put a towel around your shoulders and apply a barrier cream along your hairline to prevent staining. Use the gloves provided.
3. Mix the colour. Combine the colour cream and developer in the bottle exactly as the instructions say, then shake well.
4. Section your hair. Divide your hair into four sections for even coverage. Work on dry, unwashed hair unless the box says otherwise.
5. Apply to roots first. Roots process faster than lengths because of scalp heat, but for darker or grey hair you often start at the roots. For a lighter shade, many people apply to the lengths first and the roots last. Follow the leaflet for your specific kit.
6. Process. Leave the colour for the recommended time, usually between 25 and 35 minutes. Do not exceed the time stated.
7. Rinse and condition. Rinse with lukewarm water until it runs clear, then use the conditioner or care treatment included in the box.
Tips for Better Grey Coverage
Grey hair can be more resistant to colour because it lacks natural pigment and often has a tougher cuticle. A few simple habits can improve results.
Choose a shade that is close to your natural level, since going too light or too bright can make grey harder to cover. If you have a lot of grey, pick a natural tone, because very ash or very bright fashion tones may not cover as well. Make sure to saturate the roots fully and avoid applying too thinly.
You can also consider a root touch-up product between full colour sessions. Sprays and powders are useful for quick fixes before an event. If you need to cover stubborn white strands, you can apply colour to those areas first and leave it a few extra minutes within the recommended time window.
How to Make L’Oreal Hair Colour Last Longer
A good colour job deserves proper care. Fading and dullness are common complaints, but they are often avoidable.
Wait at least 48 hours before the first wash after colouring so the pigment can settle. Use a sulphate-free, colour-protect shampoo and a conditioner designed for coloured hair. Wash with lukewarm water instead of hot, because heat opens the cuticle and lets pigment escape.
Limit heat styling, and always apply a heat protectant before using a straightener or curling tool. Protect your hair from strong sun and chlorine with a leave-in product or a hat. Finally, use a deep conditioning mask once a week to keep strands soft, shiny and resilient. These small habits can extend your colour and reduce the need for frequent touch-ups.
Common Hair Colouring Mistakes to Avoid
Even the best L’Oreal hair colour can give disappointing results if used incorrectly. Here are the most frequent mistakes.
Skipping the patch test. Allergic reactions to hair dye can be serious, so never skip this step.
Choosing the wrong shade from the box photo. The model’s hair in the picture is not a guarantee. Your starting colour, previous dye and porosity all affect the result. Always read the chart on the back of the box.
Colouring over previously dyed hair without care. Dark dye does not lift lighter dye. If your hair is already coloured, you may need a different approach or professional help.
Not using enough product. Thin application leads to patchy, uneven colour. If you have long or thick hair, buy two boxes.
Leaving it on too long. More time does not always mean better colour and can cause damage or an unwanted tone.
Washing too soon or too often. This is one of the quickest ways to make colour fade.
Guide to Shades
L’Oreal Hair Colour Price and Where to Buy
The price of L’Oreal hair colour depends on the range, your country and the retailer. Standard box dyes such as Excellence and Casting Creme Gloss generally sit in the affordable to mid-range bracket, while specialty lines and professional products cost more. Compared with a salon colouring session, home kits are usually far cheaper, which is a big reason for their popularity.
To avoid counterfeit or expired products, buy from authorised retailers, trusted pharmacies, well-known stores or the official brand pages. Check the expiry date, make sure the packaging is sealed and compare prices across shops. Because shade availability and prices can change, always check the current listing before you purchase.
Frequently Asked Questions
Is L’Oreal hair colour good for your hair?
L’Oreal hair colour is formulated with conditioning agents and is generally safe when used as directed. However, all permanent hair colours involve chemical processes, so proper aftercare and following the instructions are important to keep hair healthy.
How long does L’Oreal hair colour last?
Permanent colour lasts until the hair grows out, though tone can fade over several weeks. Semi-permanent shades usually last around four to eight washes, and temporary colours wash out within one to a few shampoos.
Can I use L’Oreal hair colour on wet hair?
Most box colours are designed for dry hair, since water dilutes the formula. Always check the instructions on your specific product before applying.
Does L’Oreal hair colour cover grey hair?
Yes, many permanent ranges, especially Excellence, are designed for strong grey coverage. For best results, choose a natural shade close to your base colour.
How often can I colour my hair with L’Oreal?
Roots can be touched up every four to six weeks. Avoid recolouring the full length too often, as repeated chemical exposure can lead to dryness and breakage.
Can I go from dark hair to blonde with a box dye?
Lightening dark hair significantly often requires bleach or a multi-step process. A box colour may not lift enough on its own, so for a major change a professional stylist is a safer choice.
Is L’Oreal hair colour ammonia-free?
Some ranges, like Casting Creme Gloss, are ammonia-free, while others contain ammonia. Check the packaging for the exact formula.
What should I do if I get an allergic reaction?
Rinse the colour off immediately with plenty of water and stop using the product. Seek medical advice if you experience swelling, severe itching, breathing difficulty or any serious symptoms.
