Those with color-treated hair or dry scalps are often looking for ways to cleanse without stripping their scalp and hair of necessary oils. Additionally, micellar cleansers manage to remove dirt and buildup without using harsh sulfates, making them great for curly and wavy hair.

In order to sort fact from fiction when it comes to micelles for hair, we turned to board-certified dermatologists Jayne Bird, MD, FAAD, and Rachel Nazarian, MD, for their expert opinions.

Benefits of Micelles for Hair

Micelles are oil-in-water suspensions that act as surfactants when applied to the hair and scalp. Surfactants are cleaning agents that substitute soap, and they work by weakening the physicochemical binding between impurities and the hair. Surfactants dissolve these impurities, preventing them from binding to the hair shaft or the scalp. "Micelles are molecules composed of charged atoms called ions, which are often made up of hydrophilic ends (water-loving) and hydrophobic ends (oil-loving)," Bird says. Micellar cleansers provide gentle cleansing of impurities like dirt, excess oil, and hair products without stripping the hair.

  • Gently cleanses the scalp and hair: Both experts agree that micelles provide gentle cleansing to the scalp and hair that does not strip them of their natural oils. "Micelles are used as a super gentle method of cleansing; micelles are oil-in-water suspensions, essentially surfactants, that attract dirt and bacteria, but gently, without stripping moisture from your hair or skin," Nazarian says.
  • Prevents excess oil production: While micelles help to cleanse the scalp and hair of excess oil, they can also prevent the production of these oils. Bird says micelles are great for people with oily hair, as oil overproduction can happen if you strip the scalp of its oils, and micellar shampoo gently removes the oil without causing too much drying.
  • Cleans curls without sulfates: Curly and wavy hair types often avoid or infrequently use products that contain sulfates, as they can be drying and disruptive to their curl pattern. Bird says micellar shampoos are safe for all hair types, including color-treated hair, as they are sulfate-free.
  • Removes pollutants from hair: "Micelles are useful for cleansing the scalp and hair because the hydrophobic ends attract and remove sebum (excess oil) and product buildup (including dry shampoo), and the hydrophilic ends attract and remove harsh minerals, dirt, and pollution," Bird tells us. Pollutants can leave lingering scents on the hair, so micelles work to remove these odors, as well.
  • Boosts overall scalp health: Excess oil production and buildup can lead to an oily scalp and other issues. Micellar cleansers work to remove these impurities and maintain the integrity of the scalp's skin barrier.

Hair Type Considerations

Our experts agree that micelles are safe for all hair types, but they may be more beneficial for some hair types than others. "Ideally [micellar hair products] would be used on oily, thin, [and/or] delicate hair once in a while to give volume," Nazarian advises. Bird agrees and adds that they're great for giving volume to oily hair as well, saying "micellar shampoo gently removes the oil without causing too much drying—great for maintaining volume." Micellar cleansers are also helpful for those with curly or wavy hair who don't like to use sulfates often, as they can cleanse without disrupting the hair's natural oils.

When it comes to color-treated hair, the verdict on micelles is mixed. Bird mentions that since micelles are sulfate-free, they're less harsh on color-treated hair. However, Nazarian warns that micelles may remove hair coloring a bit more rapidly than basic shampoos. While Bird says micellar products are generally safe, even for those with sensitive skin, she adds that she always recommends reading the list of ingredients to ensure a given product doesn't contain anything you may be sensitive or allergic to.

How to Use Micelles for Hair

While our experts agree on what micelles can do for the hair and scalp, they have slightly different opinions on how often to use them. Since they're so gentle, Bird says that they can be used daily. Nazarian agrees that micelles are gentle, but believes that micellar cleansers should not be used in place of shampooing regularly: "Many people can use them in place of dry shampoo to remove dirt and oil without actually having to wash their hair, but again, once weekly would be my recommendation." Both experts agree that hair does need additional cleansing, which can vary depending on your hair type and how many styling products you use.

Micelles are not something you would seek out on their own, as they're created in the lab and incorporated as part of beauty product formulations. Nazarian says micelles are in shampoos, spray-on products, and even conditioners and masks. When trying a micellar cleanser in your hair for the first time, start with once a week and see how your hair and scalp respond before increasing the frequency.
