Dandruff vs. Dry Scalp: 90% of People Get This Wrong

An itchy, flaky scalp is one of the most common hair concerns  and one of the most misunderstood. Most people immediately assume it’s dandruff, but in reality, dandruff and dry scalp are two different conditions with very different causes and treatments. Confusing the two often makes symptoms worse.

At Tresses Lagos, we believe knowledge is the first step to healthier hair. Let’s clear up the difference.

What Causes Dandruff?

Dandruff occurs when there’s an overgrowth of yeast (Malassezia) on the scalp. This yeast thrives in oily environments, disrupting the natural balance of the scalp. The result? Inflammation, irritation, and flakes that are usually larger, oily, and yellowish white.

Signs you may have dandruff:

  • Persistent itching and irritation
  • Flakes that look greasy or clump together
  • Symptoms that remain even after an intense hydrating routine

What Causes Dry Scalp?

A dry scalp, on the other hand, happens when the skin simply lacks enough moisture. This could be caused by harsh products, allergic reactions, dehydration, cold weather/harmattan, or even buildup. The flakes are usually smaller, powdery, and white.

Signs you may have dry scalp:

  • Tightness or discomfort after washing
  • Flakes improve with hydrating treatments
  • Lack of shine or dullness in hair

 

Why Do People Get It Wrong?

Both dandruff and dry scalp show up as flaking, itching, and discomfort. Without expert knowledge, it’s easy to confuse the two. But here’s the problem:

  • Using an anti-dandruff shampoo on a dry scalp strips it further, worsening the dryness.
  • Applying heavy oils to a dandruff-prone scalp can feed yeast overgrowth, making flakes more stubborn.

This is why so many people struggle for years  treating the wrong condition with the wrong solution.

How To Get It Right

The key to solving scalp issues is accurate diagnosis. Once you know the root cause, you can target it with the right care.

  • For Dandruff: Look for treatments that rebalance scalp oils, reduce yeast activity, and soothe inflammation. Gentle exfoliation as well. 
  • For Dry Scalp: Focus on restoring hydration, strengthening the scalp barrier.
