When it comes to self care, we devote shelves upon shelves (and dollars upon dollars!) to our skin-care routines, but that sometimes means that our hair can end up getting the short end of the stick. Blonde, brunette, black, curly, wavy, pin-straight—regardless of how you wear it, our hair is our ultimate everyday accessory and it deserves all the time and attention we give to the rest of our selves. One easy way to give some extra TLC to our hair is to invest a little time, once or twice a week, into doing an overnight hair mask. But why? What do hair masks do exactly? And what is are the best hair masks for your specific hair concerns?

Like a souped-up conditioner, hair masks can help treat split ends and breakage caused by too much heat styling, changes in the weather, or general dryness, and if you’re a curly girl, they can even give your curls a little extra zhuzh. Angela Soto, top hairstylist and founder of Baja Studio in New York, says that the best way to use a hair mask is to “use a generous amount and leave it on for as long as possible.” She says that though manufacturers’ directions may say 10 to 20 minutes is prime, 30 minutes to an hour is best to help lock in the moisture. You can even sleep in the mask (under a shower cap, of course) and shampoo and condition it out in the morning.

The most common mistake Soto sees is people not leaving hair masks on for long enough. “The nutrients from a mask take time to absorb past the cuticle and into the cortex where you really need the most therapy, so if you’re only leaving it in the hair for a few minutes, you’re barely treating the surface of the cuticle and it has no penetration longevity.” Christin Brown, Olaplex ambassador and celebrity stylist, notes that another common mistake she sees is people using a mask on dry hair and expecting the best results. “Using a hair mask on damp hair after cleansing will give you the best results and performance because it helps to open the hair cuticle to let the mask penetrate fully, faster.”

With so many options to choose from, you’re probably wondering which to pick. Scroll down to find out the best hair masks for your hair concern, according to two top hairstylists.
