Hair loss: what should be considered before deciding the treatment?

1. How much hair fall is considered abnormal ?

Excessive and prolonged shredding more than 100 hairs a day is considered abnormal and needs to see a dermatologist to fix those problems. The quick tool for estimate of hair loss per day is internationally published and attached here.

2. Which type of hair loss do you have ? 

Dermatologist classified hair loss (Alopecia) into 2 main types; 

2.1 Non scarring alopecia (the scalp still has hair follicle opening and no scar in these types)- the most common subtype is androgenic alopecia followed by telogen effluvium and alopecia areata.

2.2 Scarring alopecia (the scalp has no hair follicle opening because of severe inflammatory reaction and finally turns to scar)-the most common subtype is lichen planopilaris followed by discoid lupus erythematosus and central centrifugal cicatricial alopecia.

However, there are many other less common types of hair loss such as syphilis, trichotillomania, or folliculitis decalvans the required dermatologist confirmation. So, if you have hair loss, please see a qualified specialist for correct diagnosis.
