Hair loss is a common problem and a beauty concern for many of us. Loose hair lying on the floor or clogging the shower drain is a common sight and unfortunately, severe hair loss is a problem that is being faced by both men and women of all age groups.

On average, an individual loses 80 to 100 strands of hair in a day. But, if you are losing your mane in significant amounts, making the scalp visible, it’s time to address the underlying health conditions.

A person undergoing hair loss may show certain signs like overall thinning of hair and patches on the scalp, sudden loss of a handful of hair.

Unless treated on time, gradual loss of hair might lead to a severe loss of hair or even alopecia. There are several treatment options available but one needs to know the actual cause behind it to get correctly treated.

Here Are A Few Common Causes:

Hair loss


The most common reasons behind hair loss are genetic conditions, hereditary factors or gradual aging. In some individuals, the hair follicles are sensitive to excessive secretion of certain male hormones in the body causing a balding or receding hairline in men and considerable thinning of hair in females.

Thyroid Factor:

The thyroid gland plays an important role in the hair cycle. Both over and under secretion (i.e. hypothyroidism and hyperthyroidism respectively) of the thyroid gland interferes in the secretion of the hormones T3 and T4. The imbalance of thyroxine hormone reduces the growth of hair at the root, therefore the falling hair doesn’t get replaced by new hair which causes balding or thinning of hair.

Unwanted Stress:

It’s a fact that excessive physical or mental stress affects the growth of hair and results in shedding of hair in huge amounts. Stress can increase the secretion of androgen (i.e. a male hormone) in the body, which causes excessive hair fall or thinning. A sudden trauma, surgery, high fever, accident or shock can also stop the growth of hair resulting in temporary loss of hair.

Hormonal Imbalance:

A variety of health issues may often cause your hormone levels to go haywire. In females, estrogen hormones play a significant role in stabilising the hair growth cycle. The secretion of this female hormone is erratic during pregnancy, childbirth, menopause or even if one is suffering from thyroid issues, which may ultimately cause alopecia, scalp infections, patchy hair loss, trichotillomania, etc.

Nutritional Deficiency:

A diet deficient in essential vitamins and minerals is also responsible for the loss of hair. Iron is extremely necessary for producing hair cell protein. Lack of it can cause premature hair loss. Vitamin B12 is important for the production of RBC and oxygen flow in the body. A diet being poor in vitamin B12 food sources can also lead to excessive hair loss and hair thinning as due to the lack of oxygen to the hair follicles, the hair shafts loosen and start falling off.

Hair Treatments:

A considerable amount of hair is lost when hair is subjected to harsh chemicals and high temperatures, such as in perming and straightening. Regular use of heat, excessive hairstyling can weaken the hair shafts from the root leading towards hair loss or patchy hair.

Reaction To Medications:

Certain medications or treatment therapy of diseases like diabetes, cancer, cholesterol, blood pressure and heart problems are harmful to the hair causing excessive hair loss as a side effect.
