Hair care is the beauty category with the most successful marketing language and the most ambiguous evidence base. The shampoo that “strengthens from the inside” (hair has no inside — it’s a dead protein structure). The serum that “repairs split ends” (split ends cannot be repaired — they can be coated to appear less split temporarily). The treatment that “feeds the hair” (hair cannot absorb nutrients — only the follicle, below the scalp surface, is alive).
Understanding what hair products can and cannot do is the foundation for choosing what’s genuinely worth buying. What products can do: clean the scalp, condition the cuticle to reduce frizz and improve manageability, coat the hair shaft to add shine and apparent thickness, provide thermal protection from heat styling, and protect colour from fading.

Best for: Colour-treated, chemically processed, or heat-damaged hair that has lost elasticity and tensile strength.
Olaplex uses bis-aminopropyl diglycol dimaleate — the specific active compound that links broken disulfide bonds in the hair’s protein structure. The chemistry is real and independently validated. For hair damaged by chemical processing (bleaching in particular) or excessive heat, Olaplex No. 3 produces measurable improvements in hair elasticity and tensile strength rather than simply coating the surface.
It’s worth being specific about what Olaplex does and doesn’t do: it repairs broken disulfide bonds, which improves the structural integrity of the hair shaft. It doesn’t repair split ends, it doesn’t grow hair, and it doesn’t produce the miraculous transformation that the most enthusiastic reviews describe. Used consistently on damaged hair, it produces real structural improvement.

Best for: Those who want the most premium haircare formulations for colour-treated and processed hair.
Oribe produces haircare at the quality ceiling of the luxury consumer market. The Gold Lust shampoo and conditioner use a combination of silk, edelweiss, and lychee alongside functional performance ingredients in formulations that produce the immediate visible results (shine, softness, manageability) that premium haircare should. The scent is distinctive and genuinely beautiful.
The price is significant and the cost-per-wash is higher than most alternatives. For those who want the best formulation available, Oribe’s quality is unambiguous.
Available at: Kérastase (kerastase.co.uk), salons, Lookfantastic
Best for: Those who want professional-grade haircare formulations at accessible luxury prices.
Kérastase occupies the space between drugstore shampoo and true luxury brands — professional quality formulations developed with professional hair knowledge, at prices that make daily use financially realistic. The Nutritive range is the recommendation for dry hair types; the Resistance range for damaged hair; the Chronologiste for fine hair concerns.
Available at: Dyson (dyson.co.uk), John Lewis, Currys
Best for: Those who blow dry frequently and want the tool that most reduces styling time and heat damage simultaneously.
The Dyson Supersonic is justified not by the brand name but by the specific technical advantages it provides over conventional hair dryers. The digital motor in the handle rather than the head produces a lighter, better-balanced tool that is physically easier to use for sustained blow drying. The intelligent heat control (measuring air temperature 40 times per second) prevents the extreme heat spikes that conventional dryers produce and that cause the protein degradation that weakens hair over time.
For those who blow dry daily, the investment in the tool that reduces heat damage is the hair care step with the most cumulative protective impact.
Available at: Bumble and Bumble (bumbleandbumble.co.uk), Lookfantastic, Space NK
Best for: A heat protectant primer for blow dry styling that also adds softness and reduces frizz.
Bumble and Bumble’s Hairdresser’s Invisible Oil is the heat protectant recommendation because it provides thermal protection up to 230°C in a formula that adds significant softness and frizz reduction without the heaviness that most heat protection sprays leave. Applied before blow drying, it reduces the mechanical and thermal damage that the styling process accumulates over time.
Available at: Briogeo (briogeohair.com), Space NK, Boots
Best for: Weekly deep conditioning for heat-damaged or colour-treated hair at a mid-range price.
Briogeo’s USDA-certified biobased mask provides intensive conditioning for hair that’s undergone chemical or heat damage without the silicone build-up that cheaper conditioning masks produce over time. The formula is clean (no sulphates, silicones, artificial colourants) and the conditioning effect is immediate and lasting through to the next wash.
Hair care produces genuine improvement through the right products for the specific hair concern. Olaplex No. 3 for the bond-building treatment that genuinely improves damaged hair structure. Oribe Gold Lust for the luxury formulation standard. Kérastase for professional quality at accessible luxury prices. Dyson Supersonic for the heat styling investment that reduces daily damage. Bumble and Bumble Invisible Oil for heat protection that also improves styling results. And Briogeo for the accessible deep conditioning treatment. Invest in the Dyson if frequent heat styling is the reality — the tool that reduces damage is worth more than the treatment that attempts to repair it.
