But what if a lack of moisture doesn’t actually cause the dry scalp itch that’s keeping you up at night? What if that “dryness” is actually an inflammatory response or a fungal overgrowth that thrives under the very oils you’re applying?

At Rooted in Violet & Co., we believe that caring for your hair is an act of self-advocacy. This winter, we’re moving beyond the surface. It is time to stop dismissing your discomfort as “just a little winter dandruff” and start looking at the science of your scalp. When we understand the difference between a thirsty scalp and a medical condition, we can stop guessing and start healing.

Why Winter Is Harder on the Scalp

Winter creates a perfect storm for scalp distress. Outside, the air is cold and holds very little moisture. Inside, we turn up the central heating, which further parches our skin and hair. This constant back-and-forth causes the skin on our scalp to lose its barrier function.

For many Black women, winter is also “Protective Style Season.” The core ingredient in our Winter hair care regimen entails tucking our ends away in braids, twists, or faux locs to shield them from the elements. While these styles are beautiful and convenient, they can create a “microclimate” on the scalp. If you are washing your hair less frequently to preserve the style, sweat, dead skin cells, and product buildup can sit on the scalp for weeks. This creates an environment where bacteria and fungi can throw a party, leading to irritation that looks a lot like “dryness” but feels much worse.

Why “Dry Scalp” Is Often a Mislabel

In dermatology, there is a significant gap in how conditions are diagnosed in darker skin tones. For decades, medical textbooks primarily showed scalp conditions on white patients. Because of this, many Black women have had their medical scalp issues dismissed as “cosmetic” or “just the way our hair is.”

The term “dry scalp” is often used as a catch-all. However, there is a significant difference between a cosmetic issue (a lack of oil/sebum) and a medical issue (inflammation or infection). If you apply oil to your scalp and the itching or flaking returns within hours—or worse, it gets itchier—you aren’t dealing with dryness. You are likely dealing with a condition that requires a targeted treatment, not just more grease. It’s not your fault that you haven’t found relief; it’s simply that you might be using the wrong tool for the job.

Common Winter Scalp Conditions Often Overlooked

1. Seborrheic Dermatitis (The Great Pretender)

This is the most common condition mistaken for dry scalp. Surprisingly, seborrheic dermatitis is actually caused by too much oil, not too little. A yeast-like fungus called Malassezia lives on everyone’s scalp, feeding on sebum (our natural oil). When this fungus grows out of control, it causes inflammation and shedding.
How it looks on us: Instead of the “redness” described in textbooks, it may look like dark brown, purple, or greyish patches on the scalp. The flakes are often yellowish and feel “greasy” or “waxy” rather than powdery.

Why winter makes it worse: We tend to wash our hair less in the winter, allowing that oil and fungus to build up.

2. Scalp Psoriasis

Psoriasis is an autoimmune condition in which your skin cells grow too quickly, piling up into thick patches. How it looks on us:

On Black skin, psoriasis often looks like thick, silvery-grey or violet-toned plaques. It usually extends past the hairline (the “psoriatic halo”).

Why winter makes it worse:

• Lack of sunlight (UV rays can help calm psoriasis) and
• Dry indoor air can trigger a flare-up.

3. Fungal Overgrowth (Malassezia/Tinea Capitis)

Fungal issues thrive in warm, damp environments. If you work out in braids and don’t dry your roots thoroughly, or if you apply heavy oils that “trap” moisture against the skin, you’re creating a greenhouse for fungus.

Typical symptoms:

• Intense itching, a “musty” smell on the scalp, even after washing
• Sometimes, there are circular patches of hair loss.

Red Flags That Deserve Medical Attention

It is okay to try a new shampoo or a lighter oil, but you should know when to stop DIY-ing and start booking an appointment. If you experience any of the following, please see a dermatologist (preferably one experienced with skin of color):
Persistent Itching:

If the itch is so intense that it interrupts your sleep or daily focus.

Soreness or Tenderness:

Your scalp shouldn’t “hurt” when you touch it or move your hair.

Thick, “Stuck” Scales:

If you have crusty patches that feel like they are “glued” to the scalp.

Bleeding or Cracking: Any time the skin barrier is broken, you are at risk for infection.

Patchy Hair Loss:

If you notice thinning or smooth bald spots accompanying the itch.

Swollen Lymph Nodes:

If you feel bumps behind your ears or at the base of your neck, along with scalp irritation.

Self-Advocacy Callout: The Winter Scalp Advocacy Violet Sheet

We don’t want you to leave your next appointment empty-handed. We created the Violet Sheet, a documentation and preparation tool designed specifically for Black women navigating the healthcare system.

This is not a product; it’s an advocacy tool.

Use it to:

Track your triggers:

Does the itch get worse after you eat certain foods, use a specific gel, or go longer than 7 days without washing?

Document your history:

List every oil, grease, and medicated shampoo you’ve tried. This prevents the doctor from suggesting something you’ve already failed.

Note the “Visuals”:

Take photos of your scalp when it’s at its worst. Sometimes, by the time we get to the appointment, the scalp looks “fine,” and our pain is dismissed.

Closing: Staying Rooted Through Winter

Your scalp is the soil from which your hair grows. You wouldn’t ignore a problem with the soil in your garden, so don’t ignore the signals your scalp is sending you. This winter, let’s shift the narrative. Advocating for answers isn’t being difficult. Wanting a healthy, comfortable scalp isn’t “too much.”
It means you’re honoring your body and choosing yourself. Pay attention to that inner nudge — if it doesn’t feel like typical dryness, it may be something more.
