Best Places to Buy Hair Color in the UK: Your Ultimate Guide to Stores, Shades and Savings

Why the right store makes a difference when buying hair colour

Choosing a hair colour isn’t just about the shade on the box — it’s about the whole experience. Do you want expert advice, a massive brand selection, or the cheapest price for a one-off root touch-up? Different stores in the UK cater to different needs. Picking the right retailer can save you time, money, and a lot of hair drama. Think of it like choosing a kitchen: one shop gives you all the gizmos and gourmet ingredients, another gives you the quick ready-meal. Both can work, depending on what you’re after.

High-street winners for home hair dye

If you prefer hands-on shopping or grabbing a last-minute kit, high-street shops remain unbeatable. Boots and Superdrug lead the pack with extensive ranges and frequent promotions. Wilko and large supermarkets such as Tesco and Asda also stock reliable, affordable home dyes. These stores are great when you need a familiar brand, quick advice from staff, or a bargain under the lights.

Boots: one-stop shop for brands and expert advice

Boots typically carries leading brands like L’Oreal, Garnier, Schwarzkopf, and salon-inspired ranges. You’ll find boxed dyes, root touch-up sticks, toners, and aftercare treatments. If you like trying before committing, Boots’ in-store beauty advisors can give pointers — plus larger stores often hold promotional offers or loyalty points that help you stretch your budget.

Superdrug: value and a wide cruelty-free selection

Superdrug is known for strong value lines and an expanding cruelty-free selection. They often run multi-buy deals and have competitive prices on developer kits and styling products. If you’re hunting vegan or ammonia-free options, Superdrug is a smart high-street stop.

Wilko and supermarkets: budget-friendly basics

Wilko and supermarkets like Tesco or Asda tend to stock the staples: tried-and-tested permanent dyes and semi-permanent colours for an everyday refresh. These places are ideal for shoppers who want a straightforward, low-cost solution — think of them as the jeans and tee-shirt of hair colour shopping: practical and familiar.

Top online retailers for hair colour in the UK

Online shopping opens up specialist brands, hard-to-find shades, and door-to-door convenience. If you enjoy comparing ingredients and reading reviews, sites like Lookfantastic, Feelunique, Amazon.co.uk, and Beauty Bay offer huge selections, customer feedback, and often exclusive lines. Online retailers are perfect when you want to explore bold or professional ranges without hopping between shops.

Lookfantastic: professional brands and exclusive deals

Lookfantastic leans toward professional and salon-quality lines — perfect if you’re after pigment-rich, fashion-forward shades. They stock brands that aren’t always available on the high street, and often bundle gift sets or sample sizes in ounces for you to try before committing to a full bottle.

Amazon and wide-market platforms: convenience and variety

Amazon.co.uk offers near-everything, from indie semi-permanent colours to bulk developer bottles. The benefit? Fast search, customer reviews, and often speedy delivery. Just double-check seller ratings to avoid counterfeit products — real hair colour deserves real quality.

Professional suppliers and salon-only purchases

If you want salon-grade pigment or big sizes for long hair, professional suppliers such as Salon Services supply beauty professionals with large-volume products. These outlets sell mixing developers in 8 oz or 16 oz bottles, 3 oz to 8 oz colour tubes, and specialist chemistry you won’t find in average drugstores. Visiting a pro supplier or booking a salon appointment often gives you access to customised formulas and bespoke shade mixing.

Salon Services: bulk sizes and salon formulas

Salon Services stocks larger format bottles and professional developer strengths, usually measured in ounces — think 8 oz or 16 oz developers — which are cost-effective if you dye frequently or have very long hair. Professionals can tailor-strength developers, toners, and colour glosses to your hair’s porosity and desired lift.

Independent salon distributors and pro-only brands

Many salons work with independent distributors to access niche brands and specialist toners. These outlets are where you’ll find custom mixes, high-lift blondes, and demi-permanent formulations designed to minimise damage. If you’re aiming for a dramatic colour change, a salon or pro supplier is the safest bet.

Drugstore dye vs. professional colour: what’s the difference?

In short: formulation, pigment concentration, and application control. Drugstore dyes are designed for simplicity — a box with developer and instructions; they’re consistent and generally good for small changes. Professional colour offers more precise mixing, a broader developer strength range, and formulas tailored to specific hair conditions. If your hair is heavily coloured, damaged, or you aim for a dramatic lift, a pro formula is like switching from a paint-by-numbers kit to a custom-mixed canvas.

How to pick the right shade online or in-store

Shade selection is where many people get stuck. Start by identifying your hair’s underlying tone: warm, cool, or neutral. Use swatches and watch virtual try-on tools on retailer sites. When in doubt, pick a shade one level lighter or darker than your natural colour to avoid surprises. For accurate purchases, many stores show product size in ounces — a single-use boxed dye is often around 2.5 oz, while professional tubes or bottles may be 3 oz or bigger.

Using reviews and virtual try-ons

Customer photos and reviews are invaluable. Online platforms and retailer apps often provide virtual try-on features that simulate colours under different lighting — a helpful guide, but not foolproof. If you’re nervous, buy a 1 oz or travel-size shade first to patch-test colour and compatibility.

Ordering swatches and samples

Some online retailers sell swatch cards or small tester pots in ounce measurements so you can check undertone and fade. Spending a bit on samples can prevent expensive mistakes — think of it as a rehearsal before opening night.

Tools and accessories to buy with your dye

Good hair colour results depend as much on accessories as on the dye itself. Pick up a mixing bowl (6 oz to 8 oz capacity is handy), a tint brush, disposable gloves, sectioning clips, and a mechanical tint bottle if you’re doing roots. Bands of foil and a timer make a big difference with balayage or highlighted looks. Buying a developer in the right ounce size (for example, 8 oz for multiple uses) will also save money on repeats.

Specialist stores for bright, pastel and alternative colours

Want cotton-candy pastels, electric blue, or unicorn hues? Brands like Manic Panic, Arctic Fox, and Bleach London feature heavily at specialist retailers. Beauty Bay and some online indie shops focus on vibrant pigments and post-bleach care kits. These stores understand that vivid colours need special prep, so they also stock high-strength clarifying shampoos and conditioners to help maintain colour between 1 to 12 washes — depending on pigment and base.

Sustainable and cruelty-free hair colour choices

More customers ask for vegan, cruelty-free, or low-impact formulas. Many high-street and online stores now carry eco-conscious lines without sacrificing performance. Look for products that advertise reduced harsh chemicals, recycled packaging in ounce-friendly formats, and transparent ingredient lists. Stores such as Superdrug and specialist online retailers are expanding their clean-beauty sections, so you can feel good about your colour and your footprint.

How to save money on hair dye without compromising quality

Want to save? Sign up for loyalty schemes at Boots or Superdrug, look out for seasonal sales at Lookfantastic, and compare prices across Tesco, ASDA and online marketplaces. Buying developer bottles in larger ounce sizes, or purchasing multi-packs of semi-permanent dyes, often reduces the per-use cost. Subscribe & save options on some platforms will also keep your favours on repeat without multiple visits to the store.

Choosing the right amount of product for your hair length

One of the most practical questions: how much dye to buy. For short hair, a single 2.5 oz box kit usually does the job. Shoulder-length hair typically needs around 3 oz, while very long or thick hair may require 4 oz or more. When using professional formulas, consider buying extra in 3 oz or 8 oz sizes so you don’t run short mid-application. A little too much dye beats a mid-process panic run to the shop.

Practical shopping checklist before you buy

Before clicking “buy” or heading to checkout, run through a quick checklist: Do you have a strand test planned? Is the developer strength right for your target lift? Have you checked customer photos and ingredient lists? Is the shade slightly adjusted for your natural undertone? Confirm the ounce sizes — both for the dye and developer — and make sure you have the right accessories in your basket. This checklist will save time and regret.

Final tips for first-time at-home colouring

If it’s your first time, choose a gentle, semi-permanent formula and practice on an inconspicuous strand first. Keep towels and an old shirt ready, use gloves, and set a kitchen timer — not your phone — to avoid over-processing. For dramatic changes, booking a salon consultation or buying a professional brand from a pro supplier is worth the extra ounce of care.

Whether you shop high-street or online, budget or pro, the UK offers plenty of places to buy hair colour. Match the store to your needs: convenience, cost, colour range, or professional quality. Take your time, read real customer photos, and pick the right accessories. With a little planning and the right retailer, you’ll walk away with a shade you love and the confidence to rock it.
