Pureology Strength Cure Strengthening Shampoo & Conditioner Duo Set for Damaged Colour-Treated Hair
Product description
What it is
Pureology Strength Cure Strengthening Shampoo and Conditioner Duo Set is a gentle, sulphate-free care pairing designed for damaged and colour-treated hair. The formulas are infused with proteins and Astra-Repair technology to help protect against colour fade while adding softer, more nourished feel to the hair. The duo is vegan and cruelty-free, aligning with ethical haircare expectations. The fragrance blends raspberry, peach, and water flowers for a fresh cleanse.
Who it’s for

This set suits those dealing with colour-treated or bleached hair that’s showing signs of damage, breakage or lack of vitality. If you prioritise colour protection and a gentle cleanse, the sulphate-free approach reduces stripping while aiming to maintain colour brightness between salon visits.
How it performs


On the surface, the kit promises stronger strands and improved flexibility. Keravis and Astaxanthin are described as working together to enhance hair flexibility and help curb future breakage. In practice, you may notice a softer feel and a more manageable strand with regular use, plus reduced colour fade on highlighted or bleached areas.

What stands out
The key differentiator here is the combination of a sulphate-free formulation with Astra-Repair, geared toward colour-treated hair. Being 100% vegan and cruelty-free adds value for shoppers seeking ethical beauty choices. The scent profile is pleasant and noticeable, but not overpowering, which helps with daily use.
Where it may fall short

If you expect dramatic frizz control or ultra-high-end salon results, this duo may not deliver that level of impact for everyone. The claims focus more on colour protection and conditioning rather than aggressive repair. Also, the lack of exact performance metrics means results can vary by hair type and level of damage.


Best use cases
It makes sense to choose this set if you want a repeatable, gentle cleansing routine that looks after colour and aims to reduce further damage. It’s a sensible option for routine maintenance between salon visits, especially if you prefer vegan, cruelty-free products.

What to check before you buy
Confirm your hair’s needs align with a gentle, colour-safe routine. If you require deeper repair or more intense scalp cleansing, you might want to explore complementary products or alternate routines. Consider whether the scent profile suits you, as some users prefer subtler or stronger fragrances.
Practical usage example



After shampooing, apply the conditioner to mid-lengths and ends, leave briefly, then rinse thoroughly. The expected outcome is smoother feel and easier detangling, which can help when styling after colour service or treatments.
Quick comparison note
Compared with standard sulphate shampoos, this duo trades aggressive cleansing for a milder approach that supports coloured hair. If you prioritise powerhouse cleansing or are sensitive to fragrance, you may prefer different formulations or a fragrance-free option.

Final verdict
Final verdict: Worth considering if you want a colour-safe, vegan duo that aims to strengthen damaged, colour-treated hair without aggressive cleansing. It’s likely to appeal to daily-use routines and those prioritising ethical ingredients. If you need deeper repair or fragrance-free options, you may want to look elsewhere.
