Dandruff or Pityriasis simplex capillitii affects human scalp during some time or the other; there is no definite age, gender or ethnicity. Sometimes dandruff affects the ears, eyebrows, nose and beard of people. Many doctors say that these dry, white flakes are result of poor hygiene but also explain that there are further causes of dandruff that might lead to chronic and recurrent disorder. Here, you find some of the major causes of dandruff –
1. Lack of proper Hair Brushing
Using the right hair comb regularly and keeping hair detangled reduce the risk of dandruff greatly. Thus, it can be deduced that lack of hair brushing leads to dandruff as the dry hair scalp is therefore not getting a chance to shed off. With proper combing and brushing you actually clear off the dry flakes on the hair scalp thus reducing the appearance of dandruff.
2. Growth of Yeast
Doctors have revealed that patients having sensitivity to yeast are more prone to dandruff. Yeast-sensitive people with chronic dandruff find it really difficult to combat this issue during the winter season as compared to warmer months.
3. Dry Scalp
This is a widely seen fact that dray scalp leads to dandruff. Usually during the winter months, this problem gets worst as the combination of cold outdoor weather and heated up indoor weather leads to flaky and itchy scalp, thus dandruff! Since these flakes are not oily they appear loosely on the hair shafts.
4. Seborrheic Dermatitis
Only dry skin is not the cause of dandruff, but people with irritated and oily skin also face this trouble. This condition is known as seborrheic dermatitis and dandruff due to this skin condition is actually severe. It affects many areas of the skin, like the backside of the ears, the eyebrows, breastbone, nose folds, apart from the scalp. The person has greasy and red skin all over with yellowish, flaky dandruff throughout.
5. Improper Hygiene
This is the most common cause of dandruff amongst school children and people living in closed groups. Lack of proper oiling of scalp and them shampooing immediately after can be one of the reasons. This leads to the build up of oils in the scalp and also the dead skin cells get loosened and flaky. Using common combs, towels and other hair accessories can also inflict dandruff.
6. Skin Diseases
Dandruff is a common side effect of many skin ailments like psoriasis, eczema and many more. It is seen that patients with these disorders are more prone to get dandruff than other people. Even other diseases like Parkinson’s disease and neurological illnesses show dandruff and seborrheic dermatitis as symptoms. If you have just recovered from strokes, heart attacks or have weak immune systems you might be more prone to dandruff than others.
Apart from the above mentioned causes, there are many more that can be said as the possible reasons to have dandruff like excessive usage of hair products, excessive shampooing, Malassezia fungus, improper diet, excessive mental stress and HIV.
