Hair products
Hair products sit outside a facial routine but share the same assessment logic here: what the formulation contains, how clearly it is disclosed, and whether it is reliably purchasable in the UK. Cleansing, conditioning and treatment steps address the hair fibre and the scalp differently, and a product that suits one often does little for the other.
Choose by where the product goes
Start with the job you want the product to do. Shampoo is the cleansing step, while rinse-out conditioner and hair masks are usually used on the lengths. A leave-in adds a separate step after washing. The front label may call all of these a treatment, so check the directions for where it goes, how long it stays on and whether you rinse it out.
If your roots get oily while the ends tangle, you can choose a shampoo and a conditioner for different jobs. You do not have to buy them from the same range. If a mask makes your hair feel heavy, compare it with your usual conditioner on separate wash days before adding another product.
What to check before buying in the UK
Match the full product name and pack size to the manufacturer's listing. A shampoo, conditioner and refill can have very similar packaging. Check whether the seller shows directions for that exact version and compare prices per 100 ml for packs of different sizes, including delivery.
Treat claims such as repair or strengthening as a starting point for checking what the brand measured. For a rinse-out conditioner, ease of combing, how the lengths feel once dry and whether there is residue are practical things you can compare at home.

How we research hair products
Nothing is published here yet. Every entry is compiled from manufacturer ingredient disclosures, published cosmetic science literature and UK retailer listings. We do not run clinical trials, and we do not publish a product until its formulation details have been checked against a source we can cite.
- Formulation: INCI lists, key actives, fragrance and alcohol status where the brand discloses them.
- Evidence: what the published research suggests for the key ingredients, and what it does not establish.
- UK availability: retailer listings and prices, with the date each was last checked. Where a price is not recent enough to quote, we say “check latest price” instead of guessing.
Results from cosmetic products are formulation-dependent and vary between people. Read our review methodology, browse the ingredient explainers or compare options in the comparison tool.
Choosing hair products
- Treat scalp concerns and length concerns as separate problems with separate products.
- Silicone content is a preference rather than a safety question for most people.
- Introduce one product at a time, as with skincare, to attribute any reaction correctly.
