Dry & Damaged Hair

Dryness and damage look identical in the mirror and need opposite products. Hair that is dry is short on moisture. Hair that is damaged has lost protein structure to bleach, heat or friction. Load a damaged head with moisture and it goes limp; load a dry head with protein and it goes brittle.

Dry & Damaged Hair — section homeHair that snaps when you brush it, splits at the ends, or feels like straw an hour after washing. Those are three different problems with three different fixes.

Frizz & Curls

Curly and wavy hair frizzes because the cuticle sits more open than it does on straight hair, so it takes water from the air and swells unevenly along the strand. Every product in this section is doing one of three jobs: putting water in, sealing it, or holding the curl shape while it dries.

Frizz & Curls — section homeFrizz is thirsty hair pulling moisture out of the air. Definition is what you get when you give it that moisture first and then seal it in before it dries.
The Best Curly Hair ProductsSix curl products spanning fine waves to dense coils, with the weight note that tells you which is yours.

Thinning & Growth

This is the category with the most marketing and the thinnest evidence. Hair loss has medical causes, including thyroid disease, low iron, hormonal change, medication and genetics, and the right first step is a doctor rather than a serum. What the products here can honestly do is reduce breakage, support scalp condition, and make the hair you have look denser.

Thinning & Growth — section homeCosmetic products can make hair look fuller and cut the breakage that costs you length. None of them treats hair loss, and this section will keep saying so.
The Best Hair Growth SerumsFive scalp serums with the evidence behind each stated plainly, and a clear line on what a cosmetic cannot do.
The Best Shampoo for Thinning HairFive shampoos for thinning hair, with a clear line between cosmetic volume and anything more.

Oily Roots & Scalp

Your scalp produces sebum continuously, so the question is never how to stop it. The question is whether the product sitting on your roots is absorbing that oil or trapping it. Dry shampoo absorbs. Clarifying shampoo strips the buildup underneath. Scalp scrubs handle the flakes and residue that neither of those reaches.

Oily Roots & Scalp — section homeGreasy roots by day two are usually a buildup problem wearing an oil problem's clothes. Strip the buildup first, then change how often you wash.
The Best Dry ShampooSix dry shampoos across sprays, powders and tinted formulas, plus the application technique that decides the result.

Oily Scalp, Dry EndsWhy this combination happens and the two-products-two-places routine that treats both without making either worse.

Color-Treated & Blonde

Toning pigment sits on the cuticle and cancels yellow. It does not lift, lighten or repair. Meanwhile the surfactant in an ordinary shampoo is the single biggest reason color goes down the drain, and bleached hair is structurally different hair that needs bond and protein work rather than moisture alone.

Color-Treated & Blonde — section homeColor fades three ways: it washes out, it oxidizes warm, and the bleach that made room for it leaves the hair porous. Each one needs a different product.
The Best Purple ShampooSix purple shampoos ranked by pigment strength, and the contact-time rule that stops blonde hair turning lilac.
The Best Shampoo for Color-Treated HairFive sulfate-free shampoos that hold color, and why the cleanser matters more than any other product.

Hair Types & Porosity

Most hair care goes wrong at the diagnosis rather than the purchase. People with fine, low-porosity hair buy the rich mask a coarse, high-porosity head needs, get a greasy flat result, and conclude nothing works on their hair. This section is the diagnostic layer: work out what you have, then take the route into the problem that matches it.

Hair Types & Porosity — section homeBefore you buy anything, settle two questions: how thick each strand is, and how readily it takes in water. Almost every product decision follows from those two.
How to Test Your Hair PorosityThree at-home porosity tests, why the float test misleads, and what each result changes about what you buy.
The Best Products for Low Porosity HairFive lightweight picks for hair that resists absorbing product, plus the heat and clarifying tricks that make them work.

Brand Reviews

Brand reviews exist because people search for them, and because the honest answer is usually more specific than the marketing. A range built around moisture will disappoint someone whose actual problem is protein loss, however well made it is.

Brand Reviews — section homeA brand is not good or bad. It is formulated for a particular kind of hair. These pages say which kind, and who should buy something else instead.
MONDAY Haircare ReviewWhat the MONDAY range is formulated for, who it suits, and the hair types that should spend elsewhere.
Native Hair Care ReviewWhat Native's short, sulfate-free formula gets you, who it suits, and where the simplicity becomes a limitation.
