Many people never consider that dandruff can lead to hair loss, but what if you have severe dandruff, will this lead to hair loss? Dandruff is an abnormal condition also known as seborrheic dermatitis which causes dry and oily skin. Sebaceous glands are responsible for creating an oily substance called sebum which is meant to protect the skin from excessive dryness.
Dandruff is a widely reported skin disorder which leads to shedding of dead skin cells from the scalp
. However the exact cause of hair loss is unknown, it could be a fungus called Malassezia furfur
which grows rapidly near the sebaceous glands on the scalp.What does Malassezia furfur do to the scalp?
If the fungus grows rapidly on the face, and scalp the normal growth of cells is agitated which leads to seborrhoeic dermatitis or dandruff.
What is the cause of severe dandruff?
The cause is not well known, however, dandruff is sometimes linked to the Malassezia fungus. A study using with took samples of 145 patients with dandruff found that 90.3% were positive for Malassezia species. Secondly, people with overactive sebaceous glands
often cause dandruff formation, this creates fungi and keratin accumulation in the cells. These cells clump together to form large flakes known as dandruff.
Dandruff usually starts at puberty, and peaks at age 20 but will become less severe in people over 50. It is also more common in African Americans where it affects nearly 80 percent of people.
Comparison of seborrheic dermatitis and dandruff
We wanted to analyze some statistics in order to compare seborrheic dermatitis with dandruff, the main difference
would be its appearance since dandruff does not cause inflammation but rather fine white flakes. The list below describes the main differences:

- Location: Seborrheic Dermatitis affects the face, upper lip, eyelids, scalp, and chest whereas dandruff only affects the scalp.
- Apperance:: Seborrheic Dermatitis causes red, inflamed patches with large oily scales, whereas dandruff causes smaller whiter flakes.
- Treatment: Antifungal shampoos and topical creams can be used to treat both however Seborrheic Dermatitis can also be treated using Topical corticosteroids
Dandruff and seborrheic dermatitis are different conditions but they share similar mechanisms, both affect the seborrheic areas of the body, and they respond to similar treatments. Their cause is linked to environmental factors like including the Malassezia yeast, sebaceous secretion, and the reaction of the immune system.
