Hair
Care, styling, treatments and hot tools, across textures rather than for one.
A titanium curling iron: what titanium does that ceramic does not, and why it is the stylists' choice for thick hair
Titanium barrels heat fast and hold high heat evenly, which is why stylists use them on thick hair, and why fine hair needs a lighter touch with one. What a spring-clamp iron is good for, and how to c
Colour-safe shampoo: what actually fades hair colour, and how much a shampoo can do about it
Colour fades a little with every wash, and more with hot water, harsh cleansers, sun and heat. What a colour-safe shampoo and conditioner change, what they cannot, and the habits that matter as much.
A long-barrel curling iron: what the extra length is for, and what heat can and cannot do to hair
The barrel's width decides the curl; its length decides how easily you reach. What the long barrel on this one is for, how to pick a temperature, and the claim about moisture to read carefully.
A shampoo for a scalp that reacts: what gentle means on a label, and what it gives up
The scalp is skin, and some of it reacts to shampoo the way a sensitive face reacts to cleanser. What leaving out sulfates, fragrance and MIT buys you, and when you would still reach for something str
A powder dry shampoo you tap on: the case for loose powder, and how to read a very small study
A dry shampoo in powder form puts the absorbent exactly where the oil is, with no propellant. What this Korean one does well, what its ingredient list is mostly for, and what twenty people can and can
A dry shampoo without the aerosol: what it soaks up, what it covers, and what it leaves behind
Dry shampoo does not clean hair; it absorbs oil and masks odour until the next wash. What this non-aerosol one does differently, and the buildup every dry shampoo leaves.
A protein leave-in: how to tell whether your hair wants protein or moisture, and what this one adds
Damaged hair usually needs one of two things, and they are opposites. A protein leave-in with heat protection helps one kind and can stiffen the other. How to tell which you have.
A leave-in called Grow Long that says it does not grow hair: how keeping length actually works
Long hair is mostly hair that did not break. A leave-in conditioner helps by cutting friction when hair is at its weakest. Credit to this one for saying plainly what it will not do.
Ketoconazole shampoo: what it treats, and the flakes it will not touch
Most dandruff is driven by a yeast that lives on every scalp. Ketoconazole goes after the yeast, which is why it works on dandruff and does nothing for a dry or product-coated scalp.
A styling oil with a heat rating: what No.7 does in two drops, and what the numbers compare
A few drops of oil can do a lot for shine and frizz. Reading the claims on this one means knowing what the clinical numbers were measured against.
A hair dryer's attachments: what the nozzle and the diffuser do, and why the cool button matters most
Most people use a hair dryer on its own and on its hottest setting. The attachments in the box, and the button most people ignore, decide more about the result than the wattage does.
High-speed brushless hair dryers: why faster air means you can use less heat
The newer small, fast hair dryers dry with airspeed rather than heat. What a brushless motor changes, what the big numbers on the box mean, and the filter most people forget.
Heat protectant: what it buys you, and the dial that matters more
It does not make hair heatproof, it buys margin. Where the damage actually comes from, why application decides most of the benefit, and the number that matters more than the bottle.
