If you notice hair loss on the top of your head, it is likely you have experience either acute (sudden) or chronic (long-term) increased hair shedding. Eventually this increase in hair loss becomes noticeable as the hair you have left gives you less coverage. If the hair loss is confined only to the top of your head this may be androgenic alopecia, if it is more widespread you are more likely to be experiencing diffuse hair loss.
Some hair loss is a natural part of ageing, but there are other factors which can increase hair loss and prevent the normal regrowth of hair. We are all born with around 100,000 hair follicles which are all at a different stage of a normal hair growth cycle. At any one time, around 90% of follicles should be actively growing whilst the others are resting in preparation to be shed. Hair loss starts to become evident when you have less than 70% of hairs actively growing.
When hair loss occurs, it is generally due to a variety of factors such as genetics, hormonal balance and nutritional deficiencies. Sometimes stress, infection and inflammation can contribute to thinning hair. If you start to notice your parting is getting wider, or you can see much more scalp there are a number of ways to help reduce hair shedding and encourage hair regrowth.
