What is Dandruff?

Dandruff is a common hair and scalp problem that causes white or yellow flakes to appear on your hair and shoulders. Many people also experience an itchy scalp or skin irritation. While it isn't dangerous, dandruff can be frustrating and embarrassing.

It happens when the scalp sheds dead skin cells faster than usual. This flaking can be occasional or ongoing, depending on your scalp condition, care routine, and overall health conditions.

Common Causes of Dandruff

Dandruff doesn't stem from just one issue. Multiple factors can lead to flakes and itching. Understanding the root cause helps you treat dandruff more effectively.

1. Oily Scalp (Seborrheic Dermatitis)

Excess oil causes skin cells to clump and form greasy flakes. It affects areas like the scalp, eyebrows, and behind the ears.

2. Fungal Infection (Malassezia)

This yeast lives naturally on the scalp but can grow excessively, irritating the skin.

3. Dry Scalp

Cold weather, dehydration, or harsh hair care products strip away natural oils, leading to flaking.

4. Product Build-up

Overuse of styling products without proper cleansing clogs hair follicles and leads to flakes.

5. Poor Hygiene

Infrequent washing can lead to an accumulation of oil, sweat, and dead skin cells.

6. Skin Conditions

Dandruff can also be linked to skin conditions like scalp psoriasis and atopic dermatitis.

Why Dandruff Treatment Needs a Tailored Approach

Everyone’s scalp is different. To truly get rid of dandruff, you must select products and routines that match your specific needs.

• Oily scalp dandruff benefits from exfoliation and oil control.
• Dry dandruff needs hydrating, natural oils and mild care.
• Fungal dandruff often requires medicated shampoo with active ingredients.

One-size-fits-all doesn't work. To treat dandruff successfully, tailor your treatment to your scalp and symptoms.

Different Types of Dandruff

Knowing the type of dandruff you have can help you choose the right solution.

1. Dry Dandruff

This type results from a lack of moisture. It worsens in winter or after using drying shampoos.

Signs:

• Small, white flakes
• Tight, dry feeling scalp
• Itching, especially in cold weather

2. Oily Dandruff (Seborrheic Dermatitis)

Excess sebum combines with dead skin cells to create sticky, yellow flakes.

Signs:

• Greasy scalp
• Yellow or sticky flakes
• Red, itchy patches on the scalp

3. Fungal Dandruff (Malassezia)

Overgrowth of the fungus Malassezia leads to inflammation and flaking.

Signs:

• Large white/yellow flakes
• Intense itchiness
• Recurrence after stopping treatment

4. Product Build-Up Dandruff

Heavy use of hair care products can cause residue and flaking.

Signs:

• Waxy or sticky flakes
• Heavy scalp feeling
• Flakes disappear after deep cleansing

5. Psoriasis vs. Dandruff

Scalp psoriasis causes thick patches that don’t easily flake off and may spread beyond the scalp.

Quick Check:

• Dandruff: Light, loose flakes
• Psoriasis: Thick, silver patches with possible pain or redness
