However, as dandruff may refer to any dryness or scaling of the scalp, not all dandruff is seborrhoeic dermatitis. [6] Seborrhoeic dermatitis is sometimes inaccurately referred to as seborrhoea. [4] The cause is unclear but believed to involve a number of genetic and environmental factors.
Dandruff is a symptom of seborrheic dermatitis, “an inflammatory skin condition that can cause itching, burning, scaling, and flakes and scales on the scalp,” she explains.
Dandruff with shed hair can be symptomatic of dry skin (shed skin scales and hairs on a dark wooden tabletop) The cause is unclear but believed to involve a number of genetic and environmental factors. [7] As the skin layers continually replace themselves, cells are pushed outward where they die and flake off. For most individuals, these flakes ...
In newborns, it causes a thick, yellow, crusty scalp rash called cradle cap, which seems related to lack of biotin and is often curable. (ICD-10 L21; L21.0) There is a connection between seborrheic dermatitis and Malassezia fungus, and antifungals such as anti-dandruff shampoo can be helpful in treating it. [44]
Fragrance-free, dye-free, and sulfate-free, this medicated dandruff shampoo is approved for those with “really sensitive skin” or fragrance allergies without causing irritation, according to ...
There isn’t strong scientific research supporting the use of apple cider vinegar for dandruff. It may stop the fungus that causes dandruff from growing, but other treatments are probably more ...
A project in 2007 has sequenced the genome of dandruff-causing Malassezia globosa and found it to have 4,285 genes. [5] [6] M. globosa uses eight different types of lipase, along with three phospholipases, to break down the oils on the scalp. Any of these 11 proteins would be a suitable target for dandruff medications.
These investigations show that the M. globosa is the species that causes most skin disease in humans, and that it is the most common cause of dandruff and seborrhoeic dermatitis (though M. restricta is also involved). [6] There can be as many as ten million M. globosa organisms on a human head. [4]
