A Definitive Guide to the Best Hair Products of All Time, According to Editors

This L'Oréal Elnett Hair Spray ($15) was once banned for nearly 30 years due to the formula's ozone-damageing chlorofluorocarbons, causing stylists everywhere to smuggle it back from France in their suitcases. Once it came stateside in 2008, we finally learned the big draw: it locks down any look but keeps strands totally touchable, not shellacked or crispy.

Ever mourn the end of a beauty product? That's us, every single time we go through a bottle of Klorane Dry Shampoo With Oat Milk ($20). It's often lauded as one of the top dry shampoos on the market, mostly for its heavy-duty, oil-absorbing powders that completely refresh hair after just a few spritzes — without the tacky feel.

There may be more scalp products on the market these days than we can count, but we'll always have room in our hearts for the tried-and-true Head and Shoulders Classic Clean Anti-Dandruff Shampoo ($24 for a two-pack). Formulated with flake-fighting zinc pyrithione, there's arguably no better (or research-backed) means of dealing with dandruff.

If you colour your hair and you've yet to try the Olaplex Hair Perfector No. 3 ($28), um, where have you been? The pro formula is a go-to for hairstylists at salons because it rebuilds the broken bonds caused by the chemical treatment process, but the at-home version is just as impressive as the OG — and just as much of a must-use.

When you need a no-fuss hairbrush to use in the shower that detangles with no pain or breakage (so, always?), Tangle Teezer The Original Detangling Hairbrush ($12) will become your go-to.

Rachel Brosnahan once told us that, while she's tried upward of "1,000" dry shampoos, she has yet to find anything better than the Pssst! Dry Shampoo ($5) — and we tend to agree. Your post-workout grease will be long gone after using this formula . . . for less than the cost of a latte.

The mastermind behind Ouai Wave Spray ($26) was once dubbed the most influential hairstylist by The New York Times (and stands as a low-key celebrity by all other accounts), so you know it's going to be good — but, plot twist, it's even better than good. Not only does it leave fine-to-wavy hair with lived-in waves, but it'll also make you smell like you own a yacht (even if you don't).

Victoria's Secret models credit the Beachwaver Co. Beachwaver Pro ($199) for their voluminous bombshell waves, but here's a secret: it's ridiculously easy to use. The curling iron features a rotating barrel with a button that switches the direction from clockwise to counterclockwise, which means you can re-create the same style with minimal effort.

We get it: scrunchies are so '90s. But try the Slip Large Slipsilk Scrunchies ($39) — which are made with silk, meaning they're gentler on your hair — just once, and you'll never go back.

The Goody Spin Pins ($6) are an absolute essential if you're prone to a sweaty neck in Summer — just create a ponytail, twist it into a bun, stab it with a spin pin, and you're good to go. (Finer hair types can make do with just one, while thicker textures may need to use both pins at once.)

Concealing grey hair with the Rita Hazan Root Concealer ($25) is impossibly easy — just act like you're a graffiti artist spraying over the colour. The formula won't budge until you wash it out, so you don't need to be paranoid about getting streaks on hats, scarves, or hands.
