These haircare specialists shared some of their best tips for keeping your scalp (and strands) healthy.

Find the Root of the Issue

While dry scalp can be caused by dry skin just like anywhere else on your body, it can also be a sign of something else: "Other common causes of a dry scalp include an irritation or allergy from a haircare product, and seborrheic dermatitis (dandruff), which may be related to a yeast called malassezia that lives on the skin," Dr. Rubin says.

The flakier your scalp is, the more likely it is that dead skin cells may mix with sebum (the natural oils from your skin) and potentially cause clogged pores.

Friese explains, "Dry scalp occurs when the scalp does not produce or hold enough moisture. Like other forms of dry skin, this can cause itching, flaking, and irritation. It can also cause the hair to look dry, since oil from the scalp helps condition the hair."

"People with dry skin are more prone to dry scalp. This means many of the things that cause dry skin can also cause a dry scalp including: dry air, especially during the winter months, excessive washing, and skin conditions, such as eczema," Friese suggests.

A dry scalp can even affect how your hair grows. Rubin continues saying, "We don’t know for sure how clogged pores on the scalp affect the hair, though some believe it can negatively impact hair health. And significant inflammation on the scalp in some cases can certainly contribute to hair loss."

To be on the safe side, it's always good to check with a dermatologist to see what's really up. Different causes require different treatments, even if dry skin is the common factor.

Choose a Shampoo for Scalp Health

Some shampoos and conditioners may strip the scalp of its natural oils, leaving it dry and irritated. "Consider avoiding sulfates in shampoo which tend to be more harsh cleansers that can strip the skin of its natural oils," Dr. Rubin says.

If scalp dryness is a problem, consider switching to shampoos and conditioners specially formulated to suit the scalp. Friese adds, "Pyrithione zinc is an antibacterial and antifungal agent. It works great for dandruff, dry scalp, and also oily scalp. It also has DHT inhibitors for people who are concerned with hair loss."

"For mild dandruff, try cleansing daily with a gentle shampoo to reduce oil and skin cell buildup. If that doesn't help, try a medicated dandruff shampoo. You may need to try more than one shampoo to find the haircare regime that works for you. You may need repeated or long-term treatment. If these options do not work, see a dermatologist for further treatment," Friese continues.

But, again, make sure to contact a professional as to how you should alter your haircare routine. Dr. Rubin suggests more frequent washings for those with seborrheic dermatitis (dandruff) with a medicated shampoo, which will help more than just a moisturizing product on its own.

Apply a Hair Oil

If dandruff isn't your main issue, "There are scalp serums, lotions, and oils that can moisturize the scalp just like you would moisturize other skin areas," Dr. Rubin says.

Replenish moisture directly to the scalp with an oil or serum specifically intended for the scalp and hair. If you're doing it at the start of your day, wet hair first to avoid too much of the product being picked up by the strands, and use a cotton swab to apply it directly to the scalp.

"I would recommend serums versus oils, as oils can clog the follicles and cause other issues," Friese adds.

At night you can be more generous with how much product you use, massaging it into the scalp and even running it through your strands.

Use Astringent Ingredients

Applying oils directly to the scalp has the potential to leave hair looking and feeling greasy. Offset this with naturally astringent ingredients like tea tree oil or apple cider vinegar.

If you're noticing a lot of product or skin buildup, you can also exfoliate your scalp similar to how you would the rest of your skin. But, make sure you're not overdoing it. "Avoid exfoliating too often so you don’t irritate your skin. And it’s best to avoid exfoliating if you have eczema or psoriasis on your scalp since the skin is already inflamed," Dr. Rubin suggests.

Try a Scalp-Targeting Treatment

If your scalp is particularly problematic, use a hair care treatment that targets the scalp. The most important thing? "Make sure your hair care products agree with your skin and are not the cause of the dryness," Dr. Rubin explains. From exfoliating scalp "facials" to masks to anti-aging serums, there are plenty of scalp-focused products on the market ready to soothe, moisturize, and revive dry, irritated scalps.

Friese adds, "A scalp massage brush may help dilate blood vessels beneath the skin, which can encourage hair growth. The use of a scalp scrub while massaging can also help remove any dead skin cells, oils, product build-up that can clog follicles causing hair loss."

Cut Back on the Number of Products You Use

While all of the previous steps require adopting new products into your hair care regimen, one of the most important steps to having a healthy, moisturized scalp might actually be cutting back on the number of products you use. Try to keep your hair care routine relatively simple, nixing harsh ingredients and chemicals and opting for a streamlined approach that makes use of natural formulas that won't irritate your scalp or strip it of oils.

It's important to remember that styling products can also react with your skin, so make sure to check into those ingredient lists, too. Look for products that have non-comedogenic ingredients, meaning they won't clog the pores on your scalp or on your face.

"Too many products can throw off the pH balance of the scalp and cause
additional issues. Cleansing the scalp and making sure it is free of product
build-up is also very important," Friese concludes.
