Watch Itchy Scalp Causes and Symptoms1. Dandruff and Seborrheic DermatitisDandruff and seborrheic dermatitis are the most common when it comes to itchy scalp causes. Itching and flaking are how the body responds to the the inflammation of the overgrowth of yeast. Yeast is typically found on the scalp and other areas of the body where more hair is located. While the presence of yeast is common, it’s the over-presence of yeast that creates the problem. In particular, a yeast called malassezia can cause excess skin cell growth and irritate the scalp. To get more specific, dandruff and seborrheic dermatitis are of a continuous spectrum of the same disease that affects the seborrheic areas of the body, and often those who have eczema will have dandruff. Dandruff occurs on the scalp and usually involves itchy, flaking skin, but you many not see actual inflammation.On the other hand, seborrheic dermatitis can affect the scalp as well as other areas of the body, but in addition to itchy, flaking or scaly skin, which can be severe, it involves inflammation. Characteristics like the immune system, genetics, emotional stress and nutrition can all affect the actual occurrence and severity of dandruff and seborrheic dermatitis. Even rosacea can contribute to an itchy scalp, as it can extend beyond the face and cause flaking, itching and redness on the scalp as well. 2. Allergic Reactions from Food and ShampoosAllergic reactions can occur from numerous sources, but two of the most common sources are from your food and your shampoo. There are so many foods, such as processed sugar, peanuts and soy products, that contain inflammation- and fungus-causing attributes, and unless you avoid them, you’re likely to have some problems.Additionally, if your shampoo or hair color contains tons of chemicals, it’s possible that your scalp is having an allergic reaction to those chemicals, known as contact dermatitis. There are options, but one of the first things you should do is stop using your current shampoo, hair color and conditioner to see if the problem subsides.3. Autoimmune DiseasePsoriasis is a chronic autoimmune disease, and psoriasis symptomsinclude raised, reddish, scaly patches on the skin or scalp. Though we know that psoriasis is hereditary, experts don’t have a clear understanding of the cause. It’s been reported that at least 10 percent of those who inherit one or more of the genes could lead to psoriasis, but only 2 percent to 3 percent actually develop the disease. It’s important that you do not let psoriasis linger without attention, as it can lead to an itchy scalp and worsen if not treated. 4. Tinea Capitis (Ringworm) or Lichen PlanopilarisTinea capitis is a fungal infection, commonly known as ringworm, that often causes infection in the scalp area. It happens due to a deep extension of the fungus into the hair follicle and can develop into round patches of hair loss (aka Alopecia areata). It often appears as a raised rash and may have black dots or a stubbly appearance. Related skin infections are often found in a man’s beard, in the groin known as jock itch, and between the toes commonly, known as athlete’s foot.Fungus can live on the dead tissue in the hair, nail and outer skin areas. Tinea capitis is more likely if you have minor skin or scalp injuries, don’t bathe or wash your hair often, or have wet skin for a long periods of time, often from sweating. It easily spreads, affecting children mostly, but usually disappears into puberty. Unlike psoriasis, tinea capitis or ringworm can spread through human or animal contact, combs and brushes, hats, or any other clothing that has come into contact with the fungus. Similarly, an inflammatory condition called lichen planopilaris causes patchy hair loss, mainly on the scalp, and can cause an extremely itchy scalp.5. Head LiceHead lice may be considered something that happens only with kids in school, but those little creatures can invade the head of an adult too. In fact, lice actually prefer clean hair.Symptoms of lice are most commonly itching on the scalp, neck and ears, which is an allergic reaction to the saliva the lice produce. Sometimes itching may not occur for two to six weeks after infestation, especially for anyone infected for the first time. The eggs of lice, known as nits, are super tiny and attach to individual hair strands. This can appear as dandruff, but unlike flakes of dandruff, they aren’t easily shaken off due to their firm grip of the hair shaft.I know this sounds pretty gross, but you may be able to see adult lice moving around the head — however, they’re actually much harder to spot than the eggs.Subscribe to this channel under the link ( Thank you very much
