Reasons for Hair loss
Hair loss can be attributed to several factors. Knowing the exact reason that is causing hair loss will help you to take steps to prevent it. Hair loss can be due to intrinsic or external factors.
Some of the intrinsic reasons causing hair loss are changes in the hormones, hair loss during pregnancy, due to stress and tension, worrying, lack of sleep, and lack of essential minerals and vitamins that help in strengthening hair roots. External reasons could be change in climatic conditions, dry and hot weather, change in the kind of water, pollution etc.
Hair loss may result if a person changes the place of residence and moves to a place where the climatic conditions are different. For example, moving from a place that has humid climate to a place that has relatively cold and dry climate can lead to hair loss due to loss of moisture and dryness.
Change in the kind of water being used for hair wash can also affect hair. For example, if the water in some place has high content of salt, if the levels of chlorine are higher, or if potable clean water is not available hair loss may set in. Hair loss may occur on contact with unclean water or water containing high proportion of chlorine, like say in swimming pool.
Direct exposure to harsh sunlight may lead to hair loss as the hair loses its moisture and gets dry and brittle. Not protecting the hair by applying hair moisturizer, or sunscreen gel, or covering it with a scarf or cap may lead to hair fall.
Poor ways of handling hair may provoke this condition. For example, using hair products that are not suitable to your hair, using inappropriate shampoo not meant for your hair type, washing your hair harshly, rubbing the scalp vigorously, disentangling the knots forcibly, running comb through wet hair can lead to hair loss.
It may also happen if you expose hair to strong heat based treatments like ironing, blow drying etc. Heat reduces the content of moisture in hair making it dry and fragile.
Poor intake to foods that help in strengthening hair (for example gooseberry, proteins, eggs, green leafy vegetables, fish, olive, essential oils) could also lead to hair fall.
