Psoriasis is a chronic skin condition that causes a buildup of skin cells in different parts of the body. These excess skin cells form silvery-red patches that can flake, itch, crack, and bleed.
Experts estimate that125 million people, or 2 to 3 percent of people worldwide, have psoriasis.
When psoriasis affects the scalp, it’s simply known as scalp psoriasis. Scalp psoriasis is a relatively common condition.
Psoriasis treatment varies based on its severity and location. Generally, psoriasis treatments for the neck andfaceare gentler than treatments used on other parts of the body, such as the head.
There’s anecdotal evidence that some home remedies may help reduce scalp psoriasis symptoms. These are best used in conjunction with medical treatments that have been proven effective.

According to two large 2016 studies, scalp psoriasis affects
Someone with psoriasis may produce more of certain types ofwhite blood cellscalledT cellsandneutrophils. The job of T cells is to travel through the body, fighting off viruses and bacteria.
If a person has too many T cells, they may begin to attack healthy cells by mistake and produce more skin cells and white blood cells. In the case of scalp psoriasis, these excess skin cells may lead to inflammation, redness, patches, and flaking.
Geneticsand lifestyle factors may also play a role in the development of psoriasis.

Cyclosporine is also sold as Gengraf, Neoral, and Sandimmune in the United States.
Biologics
Biologicsare injectable medications made from natural substances. They reduce the body’s immune response, which can decrease the inflammation and redness caused by psoriasis.
Examples of biologics used to treat psoriasis include adalimumab (Humira) andetanercept(Enbrel).
Ultraviolet (UV) light therapy
Inphototherapy, the affected skin is exposed toultraviolet (UV) light. Ultraviolet B (UVB) is effective in treating psoriasis.Laser treatmentsare especially effective for scalp psoriasis.
Regular sunlightemits broadband UVA and UVB light. The artificial light most often used in phototherapy is narrowband UVB.

- witch hazel
- coal tar

Should you peel your flakes?
Avoid peeling your flakes, as that may result in hair loss. Experts suggest combing your flakes out gently if you want to improve the appearance of your scalp psoriasis.
Dermatitisis a term used to describe various types of skin inflammation. This includescontact dermatitis(a reaction to a chemical product) as well asseborrheic dermatitis(a form ofeczema).
Like psoriasis, dermatitis can also affect the scalp. While some of the treatments for these conditions may overlap, the conditions themselves have different causes.
Scalp psoriasis is likely caused by immune dysfunction. Dermatitis is caused by various skin irritants, such as allergens.
With scalp psoriasis, you’ll notice silvery-red scales that may extend beyond the hairline. They’ll cause itching, flaking, and redness. In dermatitis, scales are white or yellowish and accompanied bydandruff.
A doctor can usually tell the difference between scalp psoriasis and dermatitis by taking a look at the affected area. In other cases, it might be trickier to tell the difference.
They might perform a skin scrape or take abiopsy. An overgrowth of skin cells will be present in cases of scalp psoriasis. In dermatitis cases, there will be irritated skin and sometimes bacteria orfungi.
Dermatitis (and seborrheic dermatitis in particular) can cause dandruff. Scalp psoriasis and dandruff share many of the same symptoms, such as:
- white or yellow skin flakes on the scalp
- mild redness
- itchiness
- dryness
- temporary hair loss
In addition, dandruff may also cause:
- dry skin on other parts of the face, such as theeyebrowsor ears
- a greasy or oily scalp
However, dandruff won’t cause the thick plaques that are typical of psoriasis. Dandruff doesn’t usually have well-defined borders either, while psoriasis plaques tend to have a well-defined red border.
Dandruff is also a lot easier to treat than psoriasis and can typically be managed with the right shampoo orhome remedy.
Speak with a doctor about any changes to your skin that don’t resolve on their own or with home treatment. A doctor will be able to design a treatment plan appropriate for you.
Home treatments may be most helpful in reducing symptoms when used in combination with doctor-recommended medical treatments.
