Scalp itches, Demodex mites on Scalp causing itching

Shampoo that is too aggressive can dry the skin of the head. This will increase the sensation of itching. If your scalp is itchy then use more delicate shampoos and products in your hair, even if you have greasy hair. Use delicate products which do not generate too much foam. Even the conditioner must be lightweight

Seborrheic Dermatitis
It is called as such because it affects the Seborrheic areas of our body, i.e. those with hairs and sebaceous glands (oil glands). These areas involve the scalp, the folds on the sides of the nose and eyebrow arches as well as the ear canal, where it produces an annoying itch. This is often the result of Demodex mite infestations and uncontrolled breeding on the skin.

Skin cycle
In the normal skin-regeneration-cycle, your old cells are rotated from deep within your skin towards the skin surface, which then go about detaching in great quantity and sizes that are still imperceptible to the eye. There are many organic causes of scalp itching, such as unfavourable environmental conditions (pollution, high humidity), improper skin care can cause imbalances that affect the natural reproduction of cells and their rotation, causing the onset of dandruff, itching, infection and Demodex mites.

Demodex mites
These may build little fortifications within your scalp which will cause red and scaly patches, crusts topped with yellowish itchy scabs, severe flaking which leads to itching and scratching which will then cause a “scaling” which is similar to dandruff. Seborrheic Dermatitis may however also be a support framework for complex diseases. You will therefore need to visit a dermatologist to determine the nature of your itching and establish the most appropriate treatment protocol. The Demodex mites that cause Dermatitis may have appeared because you have a dry, flaky or overly oily scalp. Or they may have caused the dry flaky scalp and are now breeding and causing Dermatitis.

Multiple factors
If your itchy scalp is chronic, then the causes may be multi-factorial. It may be due to an inflammatory disease that is caused by multiple concurrent factor such as genetic predisposition, exposure to stress, increased secretion of sebum (oil), the uncontrolled development of micro-organisms such as Demodex mites or yeast on the scalp.

What to Avoid
Violent/aggressive cleaning or mechanical removal of the layer of dandruff. Avoid shampoos with too much detergent (usually indicated by a lot of foam). Avoid the use of lotions containing alcohol unless required by your doctor or dermatologist. Be prepared to treat dermatitis, mites or bacterial infections. If your problem begins to persist then visit a doctor or dermatologist.

What to do
The itching of the scalp is a condition that is rather annoying as the causes may be subtle or numerous (multifactoral). These could include things such as shampoo, poor diet, stress, overworked liver, irritation from dyes or mite infestations. The first thing to do is find the cause of your itchy scalp, through either examining your home/work life, or going to your local doctor or dermatologist. You can use an antifungal shampoo or lotion. There are also many medications or supplements that affect the speed and/or amount of sebaceous secretions. You will need to choose a remedy depending on the prevailing pathogenetic component and severity of the framework, as some people are simply more genetically prone to itchy scalp problems.
