Natural Hair Cycle
One of the main causes of hair loss comprises of the natural cycle of hair. A single hair strand grows over a period of certain years, following which it falls out and gets replaced by another one. So, at any given point of time, a few of your hair will surely fall out, with combing, brushing, shampooing, toweling or just rubbing the scalp. In this case, no treatment is required.
Hormonal abnormalities comprise of yet another reason behind hair loss. Too much or too less thyroid hormone, excessive testosterone, high levels of insulin and polycystic ovary syndrome are some of the hormonal factors that can lead to thinning or loss of scalp hair.
If you are suffering from scalp inflammation, whether in the form of eczema, seborrhea, or psoriasis, hair loss is a very common symptom. It can also result from fungal scalp infections (ringworm), bacterial infections of the hair roots (folliculitis) and alopecia areata.
Local trauma is yet another cause that can be attributed behind hair loss. If you use tight hairbands, have undergone chemical hair treatments, are affected by lice or scabies, wear helmet for prolonged periods, or suffer from the psychological condition trichotillomania, hair loss might take place.
Those who are suffering from serious ailments and are undertaking heavy medications to treat the same might suffer from hair loss. Consumption of steroids, undergoing chemotherapy, and intaking certain diuretics (such as sprinolactone) come under this head.
Hair loss might be the result of certain psychological conditions as well. For instance, people who take undue stress, suffer from excessive anxiety, or are a victim of depression become prone to excessive hair fall. In this case, treating the psychological problem will put an end to hair loss as well.
Though many people are unaware of the same, genetics comprise of yet another common factor leading to hair loss. In other words, hair loss or baldness might run in your family and you might end up inheriting it from your parents or grandparents.
In many cases, it has been seen that after giving birth to a baby, many women suffer from the problem of hair loss. Though it might extend to a few months as well, the condition is definitely not permanent and will resolve itself soon. Remember, the body takes time to recover from 9 months of pregnancy.
