Healthy, shiny, bouncy, hair is the goal, right? However, “the effects of daily sun damage and the use of hot tools can cause dry, dull hair,” explains celebrity hairstylist Christopher Naselli. Good news for damaged hair: there are plenty of efficacious deep conditioners available at drugstore prices.

What to Look for in Drugstore Deep Conditioners
A Lightweight Finish
This is especially important if your hair builds up oil pretty quickly. Plant and nut oils like almond and jojoba are much thinner in texture, and tend to rinse out easily. These are great options for people looking for a way to add moisture without weighing their hair down. We love the Shea Moisture Raw Shea Butter Conditioner, which is packed with natural oils and humectants for a lightweight finish.
Thicker oils and butters, like olive and coconut oils and shea butter, are great hydrators. Not only are they thick, they sink into the hair follicles to moisturize a deeper level. Oils also work to hold the moisture into the strands so that the effects are lasting. Packed with coconut oil, the All About Curls Divine Treatment works great as a treatment mask because it’s a bit thicker.
Another important factor to keep in mind is the texture of the formula. The wrong texture has the potential to be totally ineffective or leave you an oily mess, depending on the thickness of your hair. That said, you'll want to shop smart. “Someone with thin and fine hair shouldn’t use a conditioner that will weigh down the hair or is too thick in texture, whereas someone with coarse hair should use a product that’s thick enough to coat all of the hair,” says Rugetti.
While this isn’t necessarily product specific, how you apply your deep conditioner will greatly affect the results—and how to do so varies greatly from person to person. “Application totally depends on hair texture,” says Rugetti. “For example, if your hair is oily and thin, I recommend only using it on the mid to ends of the hair, whereas if your hair is dry and coarse, I recommend applying it all over the head, from root to tip.”
How do you use a deep conditioner?
Apply a quarter size of deep conditioner to freshly washed, damp hair and comb through with a fine tooth comb. The length of time you leave the deep conditioner in your hair really depends on your preference—you can either rinse it out or leave it on overnight.
Is a hair mask the same as a deep conditioner?
No. Naselli explains that deep conditioners will make your hair smoother and softer, and should be considered more of a quick fix. “A hair mask is used as a reparative treatment for dry, damaged over processed hair that is in need of extra nourishment,” he says.
Can deep conditioner damage hair?
Since deep conditioners are packed with moisturizing ingredients, they can be too much for naturally oily hair types or if they’re not thoroughly rinsed out. “They can also cause your hair to become oily and appear greasy and can eventually clog the pores on the scalp and interfere with your natural biome,” says Naselli.
How often should you deep condition your hair?
You can use a deep conditioner a few times per week if your hair is especially dry. That said, if your hair tends to be oily, limit the use of deep conditioners to once per week.
Which is best: conditioner or hair mask?
Naselli and Gutterman love both for different concerns. “If you're looking for that daily instant fix then go for the deep conditioner,” says Naselli. That said, if your hair is super dry or damaged, they both recommend calling in a hair mask.
Should I leave the deep conditioner on my hair overnight?
Both Naselli and Gutterman recommend leaving conditioners or masks in overnight when your hair is experiencing excessive breakage or dryness. This is an especially good treatment if you’ve been using more heat tools than usual, or if your hair has been exposed to the sun.
