I Don't Have Time for a High-Maintenance Haircare Routine—This One Product Does It All

Before you take any of my beauty recommendations to heart (I've been a beauty journalist for nearly 10 years, so I have bucketloads), there's something you really ought to know about me. While I'll happily commit to an extensive 10-step skincare routine and carve out a good chunk of time every morning to apply my daily makeup products, I'm really lazy when it comes to hair. Whether I'm doing my washing it, drying it, or styling it, I want the whole ordeal to take minimal time and require minimal effort.

In fact, my inherent haircare laziness became so much of an issue when I had long hair, that I ended up getting it cut into a bob. There is nothing low-maintenance about having long hair—it takes a whole lot of time and energy to wash, style, and frankly, do anything with. But short hair requires fewer products and is infinitely easier to manage.

As it stands, my current haircare routine is down to a minimal four products—shampoo, conditioner, a salt spray (for texture), and leave-in conditioner. I've tried cutting it down to three, but swiftly learned that leave-in conditioner really does play an important role in keeping my hair soft, shiny and manageable. Essentially, it's a quicker, easier, and lower-maintenance alternative to a hair mask, and it provides essential heat protection benefits.

From hair serums to sprays, trust me, these formulas are the answer to a hardworking, low-maintenance hair routine, and so, I've rounded up nine of the best leave-in conditioners to prove it. Plus, I've also spoken to expert, hairstylist Tobias Bell, to find out exactly how to choose and use leave-in conditioner to keep your hair looking it's best. Here's everything you need to know...

1. Unite Hair 7 Seconds Detangler

Editor Review: "This is the product that started my leave-in conditioner journey after a recommendation from my hairdresser," says Freelance Beauty Editor, Grace Day.

"It worked wonders when my hair was long, since my hair is also very thick—basically a recipe for tangles. With nourishing rice proteins and UV protection, it leaves hair smooth and knot-free immediately, and healthier in the long run. If you struggle to get a comb or brush through your hair after washing, this product will sort you out."

Why We Love It: Unite's leave-in conditioner effectively detangles all hair types while also providing UV and heat protection to keep hair looking its best.

2. K18 Leave-In Molecular Repair Hair Mask

Editor review: "K18's leave-in hair mask is by far the best leave-in treatment I've ever tried," says Eleanor Vousden,Best Knockoff Luxury Clothing beauty editor. "You use it in place of conditioner on damp hair and it works by repairing hair on a molecular level, strengthening the hair shaft from the inside out. While it's expensive, a little goes a long way (one or two pumps is enough for my long and thick hair) and it really does work at repairing damage and fragile lengths. I see a noticeable difference in my hair's bounciness, shine and general health when I use it. Whenever I get balayage or overdo my hot brush, I always reach for this."

Why We Love It: Ideal for those who battle breakage and snapping, this product utilises a powerful peptide blend to strengthen hair from its core. Over time, it repairs damage caused by bleach, colour and chemical treatments, including split ends, breakage, and colour fade.

3. Ouai Leave In Conditioner

Editor review: "I've never met a Ouai product I haven't liked, and this leave-in conditioner is up there with the best—in fact, it's been my go-to since cutting my hair into a bob," says Grace, "It can be used on wet hair to detangle and strengthen, or when your hair needs a hydration boost, you can mist it onto dry hair to smooth things out and increase shine. Some leave-in conditioners can result in hair feeling heavy and coated, but this product isn't one of those."

Why We Love It: Infused with Vitamin E and amino acids, this lightweight leave-in conditioner works to nourish strands without feeling heavy or sticky.

4. Gisou Honey Infused Leave-In Conditioner

Editor review: "I love this leave-in conditioner from Gisou. I have very thick, dry hair, so I need a leave-in conditioner that really works, and this one makes my ends impossibly soft," says Who What Wear UK junior beauty editor, Grace Lindsay. "A little bit goes a long way, so I would recommend applying a small amount to start with and letting the product work its magic. The clever formula works to hydrate, detangle and protect your hair from heat, and I can't imagine my haircare routine without it."

Why We Love It: Most leave-in conditioners come in a spray bottle like this one to make things easier and less messy. Not only does this product look great on the shelf, but it means serious business for drier hair types. Infused with honey to hold hydration, strengthen, soften,and fend off further damage, it ticks all of the boxes.

5. Amika Hydro Rush Intense Moisture Leave-In Conditioner

Expert Review: "amika’s Hydro Rush Intense Moisture Leave-In Conditioner is ideal for dehydrated hair that needs a boost of moisture without feeling heavy," says Tobias "I use the Hydro Rush Leave-In Conditioner to style my hair when wet and keep my curls hydrated."

Why We Love It: Many of my curly-haired friends absolutely adore this leave-in conditioner thanks to its intense hydrating properties and for the fact that it doesn't cause curls to drop. In fact, it keeps them tight and buoyant. The spray applicator makes it easy to mist through lengths, so you can easily layer up the hydration when needed.

6. Color Wow Dream Cocktail Coconut-Infused Leave-In Treatment

Why We Love It: Formulated with fatty acids, coconut oil and emollients, this is next-level moisturising and also delivers major shine and gloss. Expect straight, smooth, and sleek hair with a glass-like finish. It's also a great choice for those with colour-treated hair too, plus the delicate coconut scent leaves your hair smelling delicious.

7. Sol de Janeiro Brazilian Joia Milky Leave-In Conditioner

Editor Review: "Over the years, I've tried many different leave-in conditioners in an attempt to master my wavy/curly strands, and what I've discovered is that less is more," says Freelance Beauty Editor, Jazzria Harris. "Rather than rich creams, liquid formulas are my go-to for lightweight hydration that nourishes my strands without coating or weighing them down. Sol de Janeiro's formula is one of my favourites. It's hydrating without feeling heavy and disappears into the hair as it dries. As well as on damp hair, I also love to use it as a refresher between washes to add definition back into my waves for a sleeker look with a little added shine."

Why We Love It: This formula is all at once conditioning, detangling, smoothing, and strengthening (I can definitely see it working for all hair textures), but the thing that really sets this above the rest is the mouth-watering smell. With a scent reminiscent of salted caramel, tropical fruit and beaming sun rays, your hair will smell like paradise all day long. If you love Sol De Janeiro's perfume mists, this is a must-try.

8. Oribe Gold Lust Restorative Night Creme

Editor Review: "I really love this product. It doesn’t leave my hair greasy, and it smells lovely. You also don't need much for it to work well, which is a bonus," says Who What Wear UK insights analyst, Sophie Cookson.

Why We Love It: Sitting somewhere between a cream and a serum, this leave-in conditioner is basically a night cream for your hair. The rich formula is designed to repair and rejuvenate hair while you sleep, restoring softness, smoothness and shine. Think of this product as an intense hair mask with no rinsing required—plus, I find that the lightweight, fast-absorbing texture means it doesn't transfer to bedding and is suitable for nightly use.

9. Noughty Intensive Care Leave-In Conditioner

Why We Love It: With sweet almond oil, argan oil, shea butter and amino acids, this hardworking formula leaves hair feeling silky smooth while fortifying strands to protect against breakage and brittleness. A top tip? Keep this tube on hand for refreshing second- and third-day hair—it will help restore definition and bounce.

What Is a Leave-in Conditioner?

"A leave-in conditioner is a lightweight conditioning product that’s applied to damp or dry hair and left in — no rinsing required," explained hairstylist Tobias Bell, "It helps hydrate, soften and protect the hair throughout the day, while also making it easier to detangle and style. Unlike traditional conditioners, leave-ins are designed to keep working after you step away from the shower."

Who Can Benefit From Using a Leave-in Conditioner?

"Pretty much everyone!!" Bell continued, "Leave-in conditioners are especially great for dry, damaged or colour-treated hair, but they’re also brilliant for fine hair when you choose the right formula. For example, amika’s Hydro Rush Intense Moisture Leave-In Conditioner is ideal for dehydrated hair that needs a boost of moisture without feeling heavy, while amika’s The Wizard Detangling Hair Primer works well across all hair types — from straight to curly — offering heat protection, smoothing and frizz control in one step."

What’s The Best Way To Apply a Leave-in Conditioner?

"The best way to apply a leave-in conditioner is to start with clean, towel-dried hair," says Bell, "Spray or work a small amount through the mid-lengths and ends, focusing on areas that feel dry or prone to tangling. Comb through to distribute evenly, then style as usual."
