Scratching your head (a common fallout of dandruff) can damage hair follicles, break roots and irritate the scalp, leading to further hair fall. Dandruff also causes irritation and inflammation, both of which weaken hair follicles, causing hair to fall out. Finally, dandruff is a sign of an unhealthy scalp, that also makes hair unhealthy, and more prone to breakage.
Dandruff directly does not cause hair loss. The itching due to dandruff impacts the hair follicles, which can lead to a certain amount of hair fall. Loss of 50-100 strands of hair on a daily basis is considered normal.
Dandruff can increase hair fall in people with androgenetic alopecia (male pattern baldness and female pattern baldness).
