It starts as a tiny itch. You're looking in the mirror, adjusting your arch, and there it is: a dusting of white flakes tangled in your brow hairs. You try to scratch it away, but that only makes it red. Then the skin under eyebrows dry patches start to feel tight, almost like the skin is a size too small for your face. Honestly, it’s annoying. It ruins your makeup, it feels scratchy, and it’s surprisingly hard to hide.
Most people assume they just need more moisturizer. They slather on a thick cream, wait a day, and find the flakes are still there, maybe even worse. That's because dryness in this specific spot is rarely just "dry skin." It’s a specialized zone. Your eyebrows sit right over the supraorbital ridge, an area packed with oil glands and hair follicles. When things go sideways here, it's usually a battle between your skin barrier, local fungi (yeah, we’ll get to that), and the products you’re using.
The Seborrheic Dermatitis Factor
If your skin is flaking but also looks a bit oily or yellowish, you’re likely dealing with seborrheic dermatitis. It sounds scary. It isn't. It’s basically dandruff, but for your face. We all have a yeast called Malassezia living on our skin. Usually, it's a quiet neighbor. But sometimes, it overgrows and starts breaking down the oils on your skin into oleic acid. If you’re sensitive to that acid—boom—inflammation and flaking.
Board-certified dermatologists, like Dr. Shari Marchbein, often point out that this condition thrives in "seborrheic" areas—places with lots of oil glands like the scalp, the sides of the nose, and, you guessed it, the eyebrows. If you notice the redness is worse when you’re stressed or when the weather turns cold and dry, this is your culprit.
It’s a bit of a paradox. Your skin feels dry, so you put on heavy oils. But if it’s seborrheic dermatitis, those oils (especially ones high in lauric or palmitic acid) are basically a buffet for the yeast. You’re feeding the fire.
Contact Dermatitis: The Makeup Traitor
Sometimes the skin under eyebrows dry issues come from the outside in. Think about what you put on your brows. Gels, pencils, pomades, dyes. These products are loaded with preservatives, fragrances, and pigments.
Contact dermatitis happens in two ways. There’s the "irritant" version, where a product simply wears down your skin barrier over time. Then there’s the "allergic" version, where your immune system decides it hates a specific ingredient, like paraphenylenediamine (PPD) found in many brow tints.
Have you switched your face wash lately? Even a foaming cleanser that’s too harsh can strip the delicate skin around the eyes. The skin here is thinner than the skin on your cheeks. It can’t handle the same level of scrubbing or high-pH soaps. If you’re using a retinol or an acne treatment like benzoyl peroxide, it might be migrating from your forehead down into your brow line while you sleep. That’s a classic recipe for localized peeling.

Psoriasis vs. Eczema in the Brows
It’s easy to mix these up.
Psoriasis is an autoimmune situation. It causes skin cells to build up way too fast. In the eyebrows, this looks like "sebopsoriasis"—a hybrid of dandruff and psoriasis. The scales are usually thicker and have a silvery sheen compared to the "greasy" flakes of dermatitis. It’s persistent. It doesn’t just go away with a bit of Lotion.
Atopic dermatitis (eczema) is more about a broken barrier. It’s intensely itchy. Like, "keep you up at night" itchy. If you have a history of asthma or hay fever, your eyebrow dryness might just be a localized eczema flare. This requires a completely different approach than the yeast-focused treatments. You need ceramides. You need lipids. You need to stop the itch-scratch cycle before you pull out your brow hairs.
The Environment Is Not Your Friend
Winter is brutal. When the humidity drops, the air literally sucks the moisture out of your stratum corneum. If you live in a place with hard water, the minerals like calcium and magnesium can settle into the brow hair and irritate the skin underneath.

Then there's the "hot shower" trap. We all love a steaming shower when it's cold, but that hot water dissolves the very lipids that keep your eyebrow skin supple. If you’re washing your face in the shower under a high-pressure, high-heat stream, you’re basically pressure-washing your skin’s natural protection away.
How to Actually Fix It
Stop scrubbing. That’s step one. People think they can exfoliate the flakes away. You can't. You’re just creating micro-tears.
The Targeted Wash
If it's seborrheic dermatitis, try a "shampoo mask." Take a tiny bit of a dandruff shampoo containing ketoconazole, zinc pyrithione, or selenium sulfide (like Nizoral or Head & Shoulders). Gently massage it into your eyebrows. Let it sit for two or three minutes. Wash it off. Do this twice a week. It kills the yeast without needing a prescription.
The Barrier Repair
If the skin is just raw and dry, look for a "cica" cream. Ingredients like Centella asiatica, panthenol, and madecassoside are gold. Brands like La Roche-Posay (Cicaplast Baume B5) or Avene (Cicalfate) make thick, soothing balms specifically designed to repair broken skin. Apply a tiny amount specifically to the brow area at night.
The Oil Audit
Be careful with oils. Everyone loves face oils, but many of them (like coconut oil) can clog the follicles in the brow or feed the yeast mentioned earlier. If you must use an oil, squalane is a safe bet. It’s biometrically similar to your skin’s own sebum and doesn't usually feed the Malassezia yeast.
When to See a Professional
If the skin is oozing, crusting yellow, or if you’re actually losing eyebrow hair, stop DIY-ing. You might have a secondary bacterial infection like impetigo. A dermatologist can prescribe a mild topical steroid (like hydrocortisone) or a non-steroidal cream like pimecrolimus (Elidel) which works wonders for facial dermatitis without thinning the skin.
Also, pay attention to your eyelids. If the dryness is spreading from the brow down to the lid, that's a red flag for a systemic allergy. Your eyes are sensitive. Don't mess around with them.

Actionable Next Steps
- The "Elimination Diet" for your face: Stop using brow gels and pencils for 72 hours. See if the redness subsides.
- Swap your cleanser: Switch to a non-foaming, fragrance-free cleanser like Cetaphil or CeraVe Hydrating Cleanser.
- The Nizoral Test: Use a 1% ketoconazole shampoo as a 2-minute brow mask tonight. If the itching stops by morning, you’ve likely found your culprit (yeast).
- Hydrate the right way: Apply a thin layer of petrolatum (Vaseline) or a ceramide-heavy cream to damp skin after washing to lock in moisture.
- Check your vitamins: Low levels of B vitamins (specifically B6 and B12) or Zinc can sometimes manifest as flaky skin around the face. It's rare, but worth a blood test if nothing else works.
