Lightweight Leave-In Conditioners Celeb Hairstylists Love to Use on Their Fine-Haired Clients
More moisture minus the weighed-down look.
Growing up, I always noticed the stark difference between my hair and that of the other women in my immediate family. Unlike my thick, curly hair, my mother and grandmother had straight, fine hair. Naturally, that meant there was a wide variety of hair products in my home. There would always be some thick curl cream or gel next to a volumizing mousse or texture spray.
Needless to say, I've learned a thing or two about what works for people on both sides of the spectrum. For example, a product that works on thick curls or coils simply wouldn't work on someone with fine hair, since it can be easily weighed down from formulas that are too heavy. This can make finding the right product for fine hair a bit of a hassle, especially when it comes to leave-in conditioner.
Sure, everyone wants that boost of moisture, but it takes the right lightweight formula to prevent hair from falling flat or looking greasy. In fact, celebrity hairstylists have to work with fine hair all the time and are pros in sourcing the best products for this specific hair type. That's why I decided to speak with three experts who know exactly which brands are with your buck. Read on for their top picks.

What to Look For in a Leave-In Conditioner for Fine Hair?
With many leave-ins on the market, it's important to know which ingredients and formula types work for your hair specifically. "If you have fine hair, you should stay away from any heavy creams; stick to lightweight spray formulas," says Cardenas. "I also recommend looking at the descriptions of the product. Usually, lightweight leave-in conditioners will always mention adding volume."
Additionally, he notes that ingredients like keratin and other proteins can help repair damage and prevent breakage. For added moisture without the heaviness, Taylor recommends lightweight hydrators like aloe, panthenol, hyaluronic acid, and amino acids.
What's the best way to apply leave-in conditioner for fine hair?
Applying leave-in for fine hair is incredibly straightforward. For the best results, Taylor suggests starting with a small amount and applying it to the mid-shaft to ends only, noting that that's where fine hair needs it the most. "Keep it off the root, use a wide-tooth comb to distribute evenly, and layer slowly if you need more," she says. "Fine hair always does better with less product, applied intentionally."
