Your shower conditioner and a leave-in can look like the same creamy product in a different bottle. The real difference is timing: one rinses out after a few minutes, and the other keeps working until your next wash.
Once you know what each one is for, building a routine gets simple. You'll know when to reach for each bottle, how much to use, and why fine hair doesn't have to skip the leave-in.
When
Conditioner: In the shower, rinse out · Leave-in: After you rinse, stays in
The short answer
Use regular conditioner every time you shampoo, then smooth a leave-in through damp hair after you rinse. Conditioner softens and detangles during the wash. A leave-in keeps moisture, shine and frizz control going until the next one.
What is leave-in conditioner
A leave-in is a light conditioner you apply after washing and never rinse out.
So what is leave in conditioner, compared with the bottle in your shower? It's thinner and lighter on purpose, so it can sit on your hair all day without making it greasy or flat. You'll find it as a cream, lotion or spray, and you use it on damp or dry hair before styling. Rinse-out, deep and leave-in are three of the main types of hair conditioner, and each one is made for a different moment in your routine.
Ours began with a promise from our founder, Babba Rivera, the daughter of a Chilean hairdresser: never launch a product that doesn't help long-term hair health. That meant a silicone-free leave-in that works like a daily moisturizer instead of a surface coating. You can read the making of our cult-favorite leave-in, from the superfruits inside to the five years since it launched.
What does leave-in conditioner do
A leave-in keeps hair moisturized, smooth and easier to style between washes.
The quick answer to “what does leave in conditioner do” is that it picks up where your shower conditioner left off.
- Adds slip, so knots comb out with less pulling
- Smooths frizz and flyaways
- Brings shine as your hair dries
- Keeps ends soft until your next wash
- Gives a blowout a smoother start
A leave in conditioner for dry hair should feel creamy and rich enough to soften your ends. Work it through damp hair from mid-lengths to ends, and add a little more if your hair still feels thirsty once it's dry.
A leave in conditioner for fine hair is all about the amount. Start with a dime-sized drop, keep it off your roots and build up only if you need to. If even that feels like a lot, our Guava Rescue Spray is a lightweight mist that detangles and hydrates.
Frizz is often the reason people start with a leave-in in the first place. Our frizz control collection gathers the silicone-free staples that pair well with it, from hair oil to flyaway gel.

How to use leave-in conditioner after you rinse
Apply your leave-in to damp, towel-blotted hair right after you rinse out your regular conditioner.
Getting how to use conditioner right comes first, because the leave-in builds on it. After shampoo, smooth conditioner over your mid-lengths and ends, give it a few minutes, then rinse.
- Squeeze out the water and blot with a towel. Press, don't rub.
- Warm a dime-sized amount of leave-in between your palms.
- Smooth it over your mid-lengths and ends first.
- Rake it through with your fingers or a wide-tooth comb.
- Add a touch more only where hair still feels dry, then style as usual.
That's how to use leave in conditioner on wash day. On second-day hair, smooth a dime-sized amount over your ends, damp or dry, to bring back softness. Before heat styling, a leave-in helps smooth strands, and a mist of Guava Rescue Spray on top adds heat protection.
For waves and curls, apply your leave-in while hair is still very wet and scrunch upward with your palms. The extra water helps it spread evenly, and scrunching encourages your pattern to form as it dries.
Tip: Use less than you think you need. You can always add more, and too much leave-in is the fastest way to flat, greasy hair.
Our pick for leave-in conditioner vs conditioner
Our pick
A leave-in stays on to care for hair all day
Regular conditioner gets a few minutes in the shower before it goes down the drain. A leave-in is lighter and stays put, so it keeps softening, smoothing and taming frizz long after you've dried off.
