Often women notice thinning on the top of their scalp compared to the hair at the back ofthe scalp.Both these conditions, male pattern hair loss and female pattern hair loss, have a stronggenetic component.However, male pattern hair loss tends to be more strongly influenced by hormonal factors.Other causes of hair loss include autoimmune types of hair loss and the commonest of these isAlopecia areata.
In Alopecia areata patients often notice or are incidentally told they have a single discrete patch of hairloss which is often a patch of bald scalp.In terms of scarring hair loss, patients often get symptoms as compared to patients with non-scarringtypes of hair loss.This can include a stinging sensation or sensation of burning or discomfort and patients mayalso experience tenderness in touch in the scalp.Looking at the scalp, there may be changes such as redness around the hair follicle orindeed larger areas of redness.Often over time, if left untreated, this can progress to a scarring patch of hair loss. where a scar is seen on the scalp.

This may be with steroid tablets, steroid creams or non-steroid based creams.Alternatives include light therapy, immunotherapy and tablet treatments to suppress the overallimmune system.There are some newer therapies that are in trial which look very promising.Treatment of telogen effluvium is looking at the underlying cause, identifying it andthen addressing it.
There are a huge number of lifestyle factors that one would consider.In terms of scarring hair loss, treatment is to reduce the inflammation to prevent the scarringfrom occurring.Therefore, early treatment is important.
A variety of creams, lotions and foams may be used on the surface of the scalp but oftentablets that suppress the immune system are needed.As with all treatments and especially so in hair loss, it’s important to balance the risk and the benefit.
