It may be characterised by flakes, but scalp psoriasis couldn’t be any more different from dandruff. Find out why with our guide tothis rarer genetic condition.
If you’re experiencing flakes, itching and redness around the scalp, it could be – in order of most to least common – one of thefollowing:
- seborrhoeic dermatitis
- scalp psoriasis
If you’ve ruled out the dandruff by using a zinc pyrithione shampoo or even stubborn dandruff with a selenium sulphide shampoo then it could be psoriasis.
Scalp psoriasis is a somewhat rare genetic condition that affects around 3% of the world’s population.
Some symptoms are similar to dandruff: as the body’s skin cells increase the rate of shedding, leading to a build-up of flakes that may be confused with dandruff.
But there are some important differences to remember:
- Rednessbeyond the hairline – you might notice it at the top of your forehead or around your sideburns too
- Flakes tend to be silver in colour – they can also be more oily than dandruff flakes
- Scaly areas– the red patches associated with scalp psoriasis are often covered by scale-like areas of dead skin
- Other parts of the body can be affected– unlike dandruff, you may experience psoriasis in other areas, such as your hands and face
What to do about scalp psoriasis
If you’ve already ruled out dandruff and seborrheic dermatitis by using dandruff shampoo for 2-3 weeks, then visit your doctor or dermatologist who can prescribe a solution for your psoriasis.
