What is Dandruff?
Dandruff is a mild form of seborrheic dermatitis, a condition associated with excess oil production and yeast growth on the scalp.
Common symptoms include:
White or yellow flakes on the scalp or shoulders
Mild redness
Itching of the scalp
Oily scalp in some individuals
Dandruff can worsen due to stress, weather changes, hormonal fluctuations, and irregular hair washing.
What is Scalp Psoriasis?
Scalp psoriasis is a manifestation of psoriasis affecting the scalp. It occurs when the immune system triggers rapid skin cell growth.
Symptoms typically include:
Thick, silvery scales
Well-defined red patches
Intense itching or burning
Scaling that may extend beyond the hairline
In some cases, scalp psoriasis may also occur along with psoriasis patches on elbows, knees, or other parts of the body.
Key Differences Between Dandruff and Scalp Psoriasis
While both conditions cause flaking, there are some distinguishing features:
Dandruff
Fine, loose flakes
Greasy or oily scalp
Usually limited to the scalp
Improves with medicated anti-dandruff shampoos
Scalp Psoriasis
Thick, silvery scales
Clearly defined red patches
May extend beyond the scalp
Often requires prescription treatment
Treatment Options
Dandruff Treatment
Dandruff usually improves with medicated shampoos containing ingredients such as ketoconazole, zinc pyrithione , selenium sulfide, or salicylic acid.
Regular scalp cleansing and avoiding excessive oil application may also help.
Scalp Psoriasis Treatment
Scalp psoriasis typically requires dermatologist-prescribed treatments, such as:
Topical corticosteroid solutions or lotions
Vitamin D analogues
Specialised medicated shampoos
Early treatment can reduce itching, inflammation, and scaling.
