7 Best Vegan Semi Permanent Hair Dyes In The UK (2026)
Switching to a best vegan semi permanent hair dye doesn't mean settling for dull colour or a product that washes out after one shower. The formulas available in 2026 deliver rich, vibrant results without animal-derived ingredients, harsh chemicals, or long-term commitment, and they've come a seriously long way.
But with dozens of brands claiming to be vegan, cruelty-free, and gentle on your hair, figuring out which ones actually perform well can eat up hours of research. You want colour that lasts, ingredients you can trust, and a shade range that doesn't leave you compromising. That's exactly what this guide is here to help with.
We've rounded up seven of the top-rated vegan semi-permanent hair dyes available in the UK right now, comparing them on colour payoff, ingredient quality, longevity, and ethical credentials. As the team behind Smart Beauty, a UK-based brand built on vegan, cruelty-free, PPD-free hair colour, we know what separates a genuinely good dye from a disappointing one. Whether you're after a bold creative shade or something more subtle, this list will help you find the right match for your hair, your values, and your budget.
1. Smart Beauty Bold Colours
Smart Beauty's Bold Colours range is a strong starting point if you want vivid, direct-application colour without animal-derived ingredients or harsh chemicals. Made in the UK, these semi-permanent dyes are fully vegan, cruelty-free, and free from PPD, ammonia, and resorcinol, making them one of the most allergy-conscious options on this list.

Vegan formula and allergy notes
Every shade in the Bold Colours range skips the ingredients that most commonly trigger scalp reactions. The formula contains no PPD, no ammonia, and no resorcinol, which means you won't need to worry about PPD sensitivity (though a general skin sensitivity test is always worth doing before using any new dye). It's also certified vegan and cruelty-free, with no animal-derived ingredients or animal testing at any stage of production.
If you have a known PPD allergy, Smart Beauty's formula makes it one of the safer semi-permanent choices available in the UK right now.
Shade range and colour payoff
The Bold Colours collection covers a wide spectrum of vivid shades, including deep reds, electric blues, rich purples, and pastel pinks. For anyone searching for the best vegan semi-permanent hair dye across bold tones, the range is competitive on both variety and intensity of colour deposit. Results are strongest on pre-lightened or naturally light hair, where a single application delivers saturated, even colour. On darker hair, results will be more subtle, so bleaching beforehand gives you the most accurate shade match.
Fade, longevity, and maintenance
You can expect the colour to last between four and eight washes depending on your hair's porosity and how frequently you shampoo. Washing with cool water and a colour-safe shampoo noticeably extends the vibrancy between applications. Smart Beauty also offers colour-refreshing products to top up fading shades, and the fade itself tends to be gradual rather than patchy, which makes switching shades or growing out the colour far less messy.
UK price and where to buy
Smart Beauty Bold Colours are available directly through smartbeautyshop.com, with individual dyes priced accessibly for regular use. Buying direct also gives you access to seasonal promotions and discount codes, including current offers on selected shades. Shopping direct also means you get the full shade range rather than a limited selection through third-party retailers.
2. Directions by La Riche
Directions by La Riche is one of the longest-standing names in the UK semi-permanent dye scene, with a loyal following built on consistent colour results and an accessible price point. It's a popular choice for both first-timers and experienced home dyers.
Vegan formula and allergy notes
The formula is vegan and cruelty-free, with no animal-derived ingredients and no ammonia, making it gentler on your hair than most permanent options. However, Directions is not a PPD-free formula, so if you have a known PPD sensitivity, check the full ingredient list carefully before purchasing.
A patch test 48 hours before application is the right move with any new dye, but it's especially important here if your scalp tends to react.
Shade range and colour payoff
Directions offers over 40 shades, spanning vivid neons, deep jewel tones, and softer pastels. Colour payoff is strong on pre-lightened hair, where a single application deposits saturated, even pigment across the lengths. On darker hair, results are more of a tint than a full colour change.
The pastel shades work best when mixed with a small amount of vegan conditioner rather than applied straight from the tube, giving you more control over the intensity.
Fade, longevity, and maintenance
You can expect Directions to last roughly four to six washes, with a gradual fade that avoids harsh banding. Washing in cool water and using a sulphate-free shampoo will extend the vibrancy between top-ups noticeably.
UK price and where to buy
Directions is priced at around £4 to £6 per tube, making it one of the most budget-friendly options when searching for the best vegan semi permanent hair dye in the UK. It's stocked widely across online marketplaces and health and beauty retailers.
3. Crazy Color
Crazy Color is another well-established UK brand with a strong reputation in the semi-permanent dye space. It's a solid pick for anyone who wants reliable, bold results without a complicated application process or a steep price tag.
Vegan formula and allergy notes
The formula is vegan and cruelty-free, with no animal-derived ingredients and no ammonia. Like Directions, Crazy Color is not marketed as PPD-free, so check the full ingredient list carefully if you have a known sensitivity. A patch test 48 hours ahead of any application is the standard recommendation regardless of which brand you use.
Shade range and colour payoff
Crazy Color offers a broad palette of over 40 shades, covering everything from vivid electric tones to softer, fashion-forward hues. Colour payoff is strongest on pre-lightened or naturally blonde hair, where the pigment deposits cleanly and evenly. On darker hair, the result reads more as a gloss than a full colour change.
If you want the most accurate shade result from Crazy Color, lifting your hair to at least a level 9 before applying gives you the closest match to the shade card.
Fade, longevity, and maintenance
Crazy Color typically lasts between four and six washes, with a fade that tends to stay fairly even across the hair rather than developing patchy lighter spots. Using a sulphate-free, colour-safe shampoo and washing in cool water will noticeably extend the life of the colour between top-ups.
UK price and where to buy
Crazy Color is priced at around £5 to £7 per tube and is widely available through major online retailers. It's a practical mid-range option when comparing the best vegan semi permanent hair dye choices on a budget.
4. Stargazer
Stargazer is a UK-based brand with a long history in alternative and creative hair colour, popular among those who want strong pigment without stepping into a salon. It sits comfortably alongside the other picks on this best vegan semi permanent hair dye list, offering reliable results at a fair price point.
Vegan formula and allergy notes
The formula is fully vegan and cruelty-free, free from animal-derived ingredients and ammonia. Like some other brands in this category, Stargazer is not specifically marketed as PPD-free, so check the ingredient list thoroughly if you have a known sensitivity before committing to an application.
Always carry out a patch test 48 hours before applying Stargazer for the first time, particularly if your skin has reacted to other dyes before.
Shade range and colour payoff
Stargazer offers a solid range of over 30 shades, covering vivid neons, deep jewel tones, and some softer fashion colours. Colour payoff is strongest on pre-lightened or naturally blonde hair, where the pigment deposits with good saturation. On darker hair, expect a subtle tint rather than a full colour result.
Fade, longevity, and maintenance
You can expect the colour to last roughly four to six washes before it starts to fade noticeably. Washing in cool water and using a sulphate-free shampoo will help you get the most out of each application, keeping the tone looking fresher between top-ups.
UK price and where to buy
Stargazer tubes are priced at around £4 to £6, making it one of the more budget-friendly picks on this list. You can find it through major online retailers and some independent beauty suppliers across the UK.
5. Manic Panic Amplified
Manic Panic is one of the most recognised names in the best vegan semi permanent hair dye market, and the Amplified formula is their most popular choice for home use. It's a conditioning, direct-application dye that colour enthusiasts around the world have trusted for several decades, and the UK availability has made it far more accessible in recent years.
Vegan formula and allergy notes
The Amplified formula is fully vegan and cruelty-free, with no animal-derived ingredients and no ammonia. It's also PPD-free, which makes it a strong option if your scalp tends to react to more conventional dyes. A patch test before your first use is still a sensible step, regardless of how gentle the formula's reputation is.
Shade range and colour payoff
Manic Panic offers an extensive palette of over 60 shades, covering vivid brights, deep jewel tones, and a selection of softer pastels. Colour deposit is strongest on pre-lightened hair, where you'll get the most accurate match to the shade shown on the packaging. On darker hair, results read more as a tint unless you've lifted to at least a level 9 beforehand.
The Amplified formula contains conditioning agents that leave hair feeling noticeably softer after application compared to many competing brands.
Fade, longevity, and maintenance
Manic Panic Amplified typically lasts between four and six washes, with a relatively even fade across the hair rather than developing patchy lighter spots. Washing in cool water with a sulphate-free shampoo will help you extend the colour between top-ups.
UK price and where to buy
Tubs are priced at around £10 to £13 and are available through major online retailers across the UK, making them straightforward to restock when you need a top-up.
6. Arctic Fox
Arctic Fox is a US-based brand that has built a strong following in the UK, largely thanks to its conditioning formula and clear ethical positioning. It's a well-regarded pick in the best vegan semi permanent hair dye category, particularly for those who want vivid colour without compromising on hair health.

Vegan formula and allergy notes
The formula is fully vegan and cruelty-free, with no animal-derived ingredients and no ammonia. Arctic Fox also donates a portion of profits to animal welfare charities, giving it stronger ethical credentials than most competitors. Crucially, the formula is PPD-free, which makes it a genuinely safer option if you have a history of scalp sensitivity or reactions to conventional dyes.
A patch test before first use is still a sensible step, even with PPD-free formulas, to rule out individual ingredient sensitivities.
Shade range and colour payoff
Arctic Fox offers over 50 shades, including vivid brights, deep jewel tones, and a growing selection of pastels. Colour payoff is strongest on pre-lightened hair, where the pigment deposits evenly with good saturation.
On darker hair, results will be minimal without prior lifting to at least a level 9, so factor that into your planning before you buy.
Fade, longevity, and maintenance
The colour typically lasts four to eight washes, with a gradual, even fade that avoids the patchy look common with lower-quality formulas. Washing in cool water with a sulphate-free shampoo extends the vibrancy noticeably between top-ups.
UK price and where to buy
Arctic Fox is priced at around £10 to £14 per bottle and is available through major online retailers across the UK.
7. Lunar Tides
Lunar Tides is a US-based brand that has grown steadily in popularity within the UK, particularly among those who want softly pigmented, pastel-forward shades alongside a small selection of deeper, more vivid tones. It sits on the more niche end of the best vegan semi permanent hair dye market, but it earns its place on this list through consistent colour results and clear ethical commitments.
Vegan formula and allergy notes
The formula is fully vegan and cruelty-free, with no animal-derived ingredients and no ammonia. Lunar Tides is also PPD-free, making it a practical option if your scalp has previously reacted to mainstream dyes or more conventional semi-permanent formulas.
A patch test 48 hours before your first application is still a smart step, even with PPD-free formulas, to catch any individual ingredient sensitivities early.
Shade range and colour payoff
Lunar Tides offers around 50 shades, with a particular strength in pastel and muted tones that are harder to find elsewhere. Colour deposit is strongest on pre-lightened hair, ideally lifted to a level 9 or above, where the pigment sits cleanly without an underlying tone pulling it off-course.
Fade, longevity, and maintenance
The colour typically holds for four to six washes, with a gradual, even fade that avoids patchiness. Washing your hair in cool water and using a sulphate-free shampoo makes a noticeable difference to how long the tone stays fresh between top-ups.
UK price and where to buy
Lunar Tides is priced at around £10 to £14 per bottle and is available through major online retailers in the UK. Availability can vary by shade, so checking stock before you commit to a colour plan is worthwhile.

Quick recap
Every brand on this best vegan semi permanent hair dye list brings something different to the table. Smart Beauty Bold Colours stands out for its PPD-free, UK-made formula and wide shade range. Manic Panic Amplified and Arctic Fox are both PPD-free and condition your hair during the colouring process. Directions, Crazy Color, and Stargazer deliver reliable results at a lower price point, though none of them are marketed as PPD-free, so check the ingredient list if sensitivity is a concern. Lunar Tides is the pick if you want softly muted pastels that are harder to find elsewhere.
