Does Dandruff Cause Hair Loss?

Dandruff—those ‍ ‌‍‌‍‍‌‍‌‍‍ pesky white flakes—is common, annoying, and often embarrassing. If you notice that alongside the flakes, your hairs are excessively shedding, then you must be wondering: Does dandruff cause hair loss?

The simple answer is that permanent hair loss resulting from dandruff is not the case.

Dandruff is a mild skin condition known as Seborrheic Dermatitis, which results from the overgrowth of a yeast that is naturally present on the scalp (Malassezia globosa). The irritation, oiliness, and increased skin cell turnover caused by that lead to the visible flakes. Even though the shedding is very frustrating, the hair follicle is not permanently damaged in the dandruff process.

The Link: How Dandruff Leads to Hair Shedding

Though the disease does not kill the follicles, the symptoms accompanying a very severe dandruff can, in fact, lead to a temporary hair shedding and thinning situation. To help the readers understand better, the article authors have summarized the information in the following two bullet points:

1. Excessive Itching and Scratching

Intense dandruff causes the patient to be very irritated and itchy. By the time you would be relieving the itch through aggressive scratching, you are damaging the hair strands and the hair root.

2.  Damage to Hair Shaft

The hair shaft is repeatedly and vigorously scratched which weakens it, thus leading to breakage and hair fall, though temporarily. Follicle Trauma: Scalp is punched with fingers in the vigorous scratching, it's the place where hair follicles are and the small injuries that can be there may even damage the delicate hair follicle and interrupt the normal hair growth cycle. 2. Inflammation and Cycle Disruption If the dandruff is not treated in time, the inflammation on the scalp will be chronic.

3. Follicle Stress

Inflammation which is around the hair follicle and lasts for a long time, can make the environment a very difficult one, thus putting stress on the hair root and very likely it could be the reason for a premature pushing of hairs into the shedding (telogen) phase. This may cause the sudden increase of the hair shedding which can be recognized as Telogen Effluvium.
