Predominant hair diseases

Hair play an important role in enhancing the natural beauty of the person but every human is susceptible to hair loss at some point in their lives. This can happen due to age, stress, hormonal imbalance, poor diet, and attack of bacteria or fungi and can also occur due to the different hair diseases. All these factors result in poor growth of hair and ultimately hair loss occurs that leads to baldness.


Different hair diseases
Some of the hair diseases that result in hair fall are discussed below

  • Alopecia Areata
    It is an auto immune disorder in which the white blood cells of the body invade the hair follicles and thus result in hair fall. It is one of the commonest and most wide occurring hair diseases. It also hinders with the hair growth permanently and thus the person can become bald permanently. It can spread all over the body and small patches of baldness occur on different parts of the body.


  • Tinea Capitis
    This fungal infection is known as lower age disease and affects the children below the age of ten mostly. It is called the ‘Ringworm of the scalp’. Bare patches of skin form not only on your scalp but it can affect the eyebrows and eyelashes also.


  • Androgenic Alopecia
    The development of hair follows a cycle that includes different stages and in this disease the first stage of hair development also known as Anaga phase becomes shorter and hair do not develop properly. This is a genetic disease in which the hair follicles that form become thinner than that they normally are. The thin hairs that develop ultimately detach from the scalp and thus result in hair loss.


  • Telogen Effluvium
    This hair disease also results from the change in lifecycle of the hair development. The hairs become thin as they remain in the telogen phase also known as the resting phase for a long time interval. This thinning of hairs results in the hair loss. Stress, poor nutrition and hormonal imbalance trigger this disease and can make you bald very fast.

  • Alopecia Universalis
    This hair disease resembles with Alopecia areata. The hair loss occurs in all parts of the body. The two diseases differ in a way that in Alopecia universalis the hair loss occurs at a much fast rate. This generally referred as an advance form of Alopecia aerata as it can result in the complete hair loss causing baldness.


  • Pili annulati
    This disease can affect in any stage of the life. It can affect both the hairs of the scalp and the face and results in light and dark banding in the affected hairs. This disease is genetic and the effected hair cannot be seen normally with the naked eye and the proper diagnosis of the disease also occurs under the microscope. It is more difficult to look up for the affected hair in the people that have dark colored hair.
