Best Leave-In Conditioners for Fine, Straight Hair
Leave-in conditioners are an essential part of my haircare routine, and the good ones are always worth the price. I like to use leave-in conditioner at least twice a week, whether it’s as a self-care treatment or as a way to prep and protect my hair prior to heat styling it, but because I’ve been using them for so long, I’m extremely picky. I want a leave-in conditioner to leave my hair hydrated (not just superficially soft), reduce frizz without leaving a film, not be sticky or crunchy while it’s in my hair, and also easy to wash out. I’ve tried countless products, and these are the ones that I can’t live without. The main reason I have quite a few on the list is because I get bored with scents easily, but I could also just stick to one off of this list and be set for life.

dae mirage mist leave-in conditioner
I loved dae’s old leave-in conditioner that was unfortunately discontinued, but their improved version works almost as well, and did fix some of the spray issues that the first bottle had. Dae’s in-shower conditioners are not my favorite, but their leave-in conditioner is worth the price and does a great job of reducing frizz, adding hydration, and making your hair silky smooth. It also has their signature citrus scent, which feels like summer in a bottle without being too overpowering.
k18 leave-in molecular hair mask
This product is so expensive that I really didn’t want to love it as much as I did, but it really feels like a miracle worker for dry hair and a little goals a long way. After testing a shampoo that led to lots of breakage, I credit this leave-in with preventing my split ends from getting any worse, even as I continued to use hot tools a couple times a week. To get the most out of it, I like to apply it to damp hair in the morning and leave it in all day, really letting it soak in and work its magic; it’s a great weekend self-care treat that leaves your hair visibly stronger, shinier, and softer.
crown affair leave-in conditioner cream for hydrated hair
Slightly less expensive than the K18 mask, this leave-in still feels luxurious and actually makes a difference. It doubles as a heat protectant which helps justify the $48 price tag, and a little goes a long way; I’ve had mine for months and have barely made a dent in it, even with regular use. As a cream, it’s easy to work into your hair and reduces frizz yet doesn’t leave it feeling crunchy. I like to apply this to damp hair and then let my hair air dry naturally; it gives it a natural bend and looks done without being too polished, so it feels like this leave-in works into your hair routine, rather than something you have to schedule out.

unite hair 7SECONDS detangler leave-in conditioner
If you’re looking for a leave-in conditioner that you can use daily, this one is your go-to. It’s extremely lightweight yet hydrating and also doubles as a heat protectant. I use this anytime I curl my hair, and I have noticed less damage over time since incorporating it into my routine. What really makes this product a win for me is how it prevents tangles when I’m spending extra time outside, whether it’s at the beach or on a particularly windy day, so I always pack it when I travel.
davines oi all in one milk
Davines is one of my go-to brands, and this hair milk is truly worth the money. I prefer it over the Oi Oil, which tends to sit on my hair rather than absorb in and add hydration. The scent is stronger but leans more masculine, so you may prefer it if you don’t like fruity or floral scents. While it is technically a leave-in conditioner, I use this mask as a treatment because it’s a heavier product. Too much will leave your hair a little crunchy (but it becomes super soft when you wash it out), and it’s a little heavy on my fine hair to try to style after applying. I like to use this once a month on a day when I’ll be home for a couple hours, and my hair is noticeably softer and less frizzy after using.
moroccanoil all in one leave-in conditioner
Moroccanoil is known for products that hydrate your hair and add tons of shine, and their leave-in conditioner is no exception. I find it to be lighter than their oils, so it feels more fine-hair friendly. This reduces the frizz and adds moisture back into the ends of my hair, and I do feel like it helps minimize split ends the more I use it. The bottle isn’t the most functional; I know some people have issues with it spraying evenly, so I wouldn’t recommend this one for travel.
