Can Stress Cause Dandruff? The Science Explained
If your dandruff tends to flare up during high-stress periods, you're not imagining it. The link between stress and dandruff is real and well-documented in dermatology research.   How Stress Affects Your Scalp   Stress doesn't directly cause dandruff, but it creates conditions in which dandruff thrives. When you're under chronic stress, your body produces elevated cortisol. Cortisol influences your immune system and disrupts the skin's normal protective functions, including the barrier that prevents overgrowth of Malassezia yeast.   Malassezia is the primary driver of dandruff. It lives naturally on... Read more...
Seborrheic Dermatitis vs. Dandruff: What's the Difference?
Dandruff and seborrheic dermatitis are often confused — they share symptoms, have overlapping causes, and are treated with many of the same ingredients.

Is Dandruff Contagious? What You Need to Know
One of the most common questions people ask when they notice flaking on their shoulders is whether dandruff can spread from person to person. The short answer is: no, dandruff is not contagious.   What Causes Dandruff?   Dandruff is caused by a combination of three factors: a naturally occurring scalp yeast called Malassezia, your scalp's oil production, and how sensitive your skin is to that yeast. All three factors are internal — determined by your biology, not by contact with another person.   Malassezia lives on virtually everyone's scalp.... Read more...

Does Caffeine Actually Help Hair Growth? What the Science Says

Hydrocortisone for Scalp Inflammation — Why It Belongs in Your Dandruff Routine
