While many of us reach for our favorite leave-in conditioner or a nourishing hair mask when our hair needs a little extra TLC, scalp exfoliation is an often overlooked step in our hair care routine. But just like the skin on your face and body, the scalp needs regular exfoliation, too.

From removing product buildup to improving blood circulation and hair growth, scalp scrubs and other exfoliating tools offer a range of benefits that affect not only the scalp, but also the overall look and feel of your hair.

To learn more about scalp scrubs and what to look for when shopping for a product, Shop TODAY asked three hair and scalp experts to weigh in. Read on for their expert advice and use the links below to find the best scalp scrub and exfoliating product for you.

What are the benefits of using scalp scrubs?

"Like the skin on our bodies and face, our scalp sheds dead skin and secretes oil and sweat — all of which contain bacteria. Product residue, pollution and dirt can also build up on the scalp and ultimately lead to clogged pores and hair follicles," says Natalie Palomino, master hairstylist and the founder of North Authentic, an online source for expert-prescribed hair care routines.

These clogged hair pores can stop hair from growing, explains celebrity hairstylist Joel Warren, who adds that scalp scrubs and scalp exfoliants can help unclog the pore and allow the hair to grow.

Chasity Shipman, a certified AMCA trichologist and hair loss specialist, adds that exfoliating the scalp also helps in promoting healthy hair growth by waking up the follicles. "A tight and dry scalp will not encourage hair growth, but rather slow it down or cause shedding due to lack of stimulation and blood circulation," she says. "Scalp exfoliation is [also] great for those who suffer from scalp disorders such as psoriasis, [scalp] eczema and seborrheic dermatitis."

What to consider in scalp scrubs and other exfoliants

When shopping for a scalp scrub or chemical scalp exfoliant, it’s important to consider your hair type and any scalp issues, as well as personal preferences, Palomino tells us. To start your search, consider these four factors to help narrow down your options.

Type: A physical exfoliant, like a scrub, works to buff off unwanted debris, like dead skin and product buildup — whereas a chemical exfoliant uses acids or enzymes.

Scalp issue/hair type: "Those with extremely thick, dense hair may find it difficult to rinse some physical exfoliants. Those with scalp sensitivity or scalp issues (like psoriasis, scalp eczema or dermatitis) may also find physical exfoliants too harsh and therefore opt for a chemical exfoliant," she says.

Key ingredients: “Chemical exfoliants generally contain ingredients such as glycolic acid, salicylic acid or glycyrrhetinic acid. Physical exfoliants contain ingredients like sugar or salt crystals, pumice or clays (kaolin and bentonite),” she explains.

Usage instructions: Pay attention to the application instructions on the specific product label. In most cases, physical exfoliants should be applied on a wet scalp and massaged in circular motions, whereas chemical exfoliants are generally applied on a dry scalp prior to shampooing.

Aftercare: Moisturizing your scalp following exfoliation is always recommended, advises Palomino, who recommends a moisturizing shampoo and conditioner. But she also suggests staying away from applying heavy creams or oils directly to your scalp. “Look for moisturizing products that are lightweight and non-greasy,” she adds.

How do I use a scalp scrub?

Use the right tools. "The proper way to exfoliate the scalp would be using the ball of your fingertips or a scalp massage device," says Shipman.

Go gently, especially if your scalp is sensitive. Use small, circular motions and be gentle to avoid irritation, then rinse and repeat. If you have a delicate scalp, you may want to consult a professional before starting.

Wait until your scalp is clean. Warren also suggests rubbing your scalp for two to five minutes before proceeding with shampoo. Wait for your hair to form suds if you want to ensure your scalp is completely clean.

Questions about scalp scrubs, answered by experts

How often should I exfoliate my scalp?

“The frequency of exfoliation usually depends on the level of dry to oily scalp that you experience. Oily scalps generally should be exfoliated once per week, whereas dry, sensitive scalps should be exfoliated once every 14 days or more,” Palomino says.

Exfoliating more frequently than this can cause issues on the scalp, making it sensitive and potentially causing it to overproduce oil, adds Shipman. “Allow time for the scalp to produce its own natural oils to nourish and keep the scalp healthy."

Does exfoliating my scalp help with hair growth?

“Yes, buildup can clog the hair follicle and impede hair growth, causing slowing of growth or worse, hair loss. Exfoliating the scalp sets the stage for a clean, healthy follicle to work efficiently, and as a result can help with hair growth,” says Palomino.

Is using scalp scrubs or exfoliants good for my scalp and hair?

Scalp exfoliation offers multiple benefits for the scalp and hair. In fact, one 2018 study found a link between scalp health and hair growth and quality. According to the study, scalp exfoliation can increase hair fullness and reduce hair shedding while controlling scalp Malassezia levels — a type of yeast that causes damage to the hair follicles.
