5 Tips for Soothing a Dry, Itchy Scalp

Having an itchy scalp is a concern that most of us can relate to on some level. Usually, the itching is transient, lasting no more than a couple of minutes. But if your scalp is frequently dry and itchy, it’s a sign that your haircare routine needs an adjustment, stat.

Whether your scalp only itches occasionally or the itch is persistent and accompanied by irritation and flaking, addressing the problem typically requires reassessing your scalp care routine. Ahead, learn what can cause itching and discover how to soothe an itchy scalp with a few simple tweaks to your current routine.

What Causes an Itchy Scalp?

Both external factors (like your haircare routine) and internal factors (like having a dry skin type) can contribute to an itchy, uncomfortable scalp. Here are a few of the most common factors of persistent itchiness.

Dryness

Much in the same way that having dry skin can make your arms or legs feel itchy, scalp dryness can make your scalp itch, too. Dryness may be due to genetic factors—for example, having a dry skin type—or it can be due to exposure to environmental stressors, such as cold, dry winter air.

Dandruff

Dandruff is a common scalp concern that can cause the skin on the scalp to flake, peel, and shed. It’s sometimes caused by dryness, but can also occur if your scalp is oily. If you have dandruff, be sure to bring it up with your dermatologist at your next check-up—they may be able to recommend treatments to help reduce itchiness and flaking.

Product build-up

According to the American Academy of Dermatology (AAD), not washing your shampoo out thoroughly enough can irritate your scalp, potentially causing itching and discomfort. The same goes for leave-in products, like hair serums and leave-in conditioners—pretty much any product build-up can contribute to itching and discomfort.

Overuse of harsh products

You’re probably aware that coloring your hair can damage your strands, even with the proper technique. What you may not know is that frequently bleaching or dyeing your hair can irritate your scalp, too. If your scalp itching tends to coincide with your color touch-ups, chemical processing may be to blame.

Certain skin concerns

Per the AAD, skin concerns such as psoriasis and atopic dermatitis can, in some cases, contribute to an itchy scalp. Fungal infections, such as ringworm, can also contribute to itching. If your scalp is extremely itchy or the itching is accompanied by redness, pain, or discomfort, it’s a good idea to contact your doctor.

How Do You Stop an Itchy Scalp?

If you’re wondering what to do for an itchy scalp, don’t worry—you’ve come to the right place. Ahead, we’re sharing five tips to help soothe discomfort, reduce itching, and promote a more balanced, healthy-feeling scalp.

1. Use a gentle shampoo

Depending on your hair type, you may not need to wash your hair daily (or even every other day). Eventually, however, you’ll need to lather up—and when you do, it’s best to use a gentle, non-stripping shampoo to avoid drying out your scalp. The L’Oréal Paris EverPure Sulfate-Free Moisture Shampoo is an excellent option for all hair types. The sulfate- and paraben-free formula with rosemary oil gently cleanses the hair without stripping it of moisture, leaving your strands sleek, shiny, and up to two times more moisturized. The mild formula is also color-safe, so you don’t have to worry about it dulling your salon or DIY color.

2. Apply conditioner only to the mid-lengths and ends

After shampooing, you’ll usually want to apply conditioner to help hydrate and nourish your hair. But if you’re prone to itching, be careful not to apply your conditioner too close to your scalp—doing so can contribute to buildup. Instead, work your conditioner throughout your mid-lengths and ends to help hydrate the drier parts of your hair without weighing down your roots. As for which conditioner to use, we love the L’Oréal Paris EverPure Sulfate-Free Moisture Conditioner. Use it every time you lather up for soft, shiny-looking strands.

3. Exfoliate your scalp

While they’re not a cure for an itchy scalp, exfoliants can be a great asset to your hair and scalp care routine, as they help whisk away dead skin cells that can contribute to itch-causing buildup. Scalp scrubs are one option, but they may be too harsh for those with sensitive or irritated scalps. Instead, try a gentle exfoliating scalp serum, like the L’Oréal Paris Elvive Hyaluron + Pure Oil-Erasing Serum for Oily Hair. The skincare-inspired formula with salicylic acid and hyaluronic acid helps remove scalp residue while leaving the hair feeling hydrated for up to 72 hours. Plus, it’s suitable for all hair types (even color-treated hair). To use it, apply the liquid formula directly to your scalp and lightly massage it in for about five minutes. Allow the formula to sit for another 15 minutes, then hop in the shower and lather up with your chosen shampoo.

4. Target product build-up

If your scalp woes are due to product build-up, using a clarifying shampoo once in a while might be an effective (and simple!) itchy scalp remedy. These purifying formulas are designed to remove oil, dirt, and product residue to deliver a deeper clean than your everyday shampoo. Because they’re so effective, clarifying shampoos shouldn’t be used daily—once per week is usually plenty.

As for which clarifying shampoo to use, we’re partial to the L’Oréal Paris EverPure Sulfate-Free Clarifying Shampoo with Antioxidants. The enriching formula helps remove impurities without stripping color, leaving your scalp and strands feeling clean and hydrated. After cleansing, replenish moisture with the coordinating L’Oréal Paris EverPure Sulfate-Free Restoring Conditioner with Antioxidants (just remember to apply it only to your mid-lengths and ends).

5. Consult your dermatologist

As mentioned above, an itchy scalp can sometimes be caused by skin concerns or medical issues. If the itching is severe or tweaking your hair routine isn’t providing much relief, consider consulting your dermatologist. They should be able to help you identify the underlying cause of your itching and can provide expert advice on how to treat your itchy scalp.
