Dry hair is a type of hair that results from inactive oil glands where the hair doesn’t get sufficient moisture and oil to preserve its shine and texture.
The lack of oil and moisture can make the hair brittle, dull and hard.
It can occur due to several causes. Accumulated oil also blocks the pores and prevents the oil from flowing to the hair and causes dry hair.
Too much washing of hair is the main cause of dry hair. Washing your hair regularly, especially with harsh shampoo can make your hair look dull and straw-like texture because the chemicals in the hard shampoo not only wash out the dirt but also the protective oils of the hair.
Dry hair can also result from bathing with hard water. That water that is supplied to you may contain chemicals (calcium, chlorine, iron), which can cause a damaging effect on your hair.
When this water is used for bathing, an electrochemical process takes place in the hair and leads to dry hair. Swimming or bathing in pools and spas with chlorinated water also causes dry hair.
On the other hand, the heat from blow-dryers, curling irons, straightening irons, and electric rollers also result in dry hair, as the hot air damages the strands of the hair and makes the hair dry and brittle.
The chemical treatment for hair also causes hair dry. The chemicals of hair treatments such as peroxide bleach, hair relaxing chemicals, perm chemicals, and color developer also result in dry hair.
Even some environmental factors cause dryness in the hair. The changes in the climate such as low humidity, hot temperature causes your hair dry. Over exposure to the sun also result in dry hair, as it damages the outer layer of the strand that protects the hair.
Person who spends most of the time outside can easily get dry hair, as the sun, wind, dust, pollution damages the protective layers of the hair.
Following an unhygienic diet also causes dry hair. A diet that lacks the essential nutrients for the body to maintain the oil levels and makes the hair healthy can result in dry, brittle and damaged hair.
On the other hand, there are certain health conditions that can result in dry hair.
Anorexia is a condition that results from self-imposed starvation, which in turn results in dangerously thin, lack of nutrients to function properly. The nutrients that are essential to keep the hair shiny and soft will be short of and causes dry hair.
Hypothyroidism is another condition where the body produces insufficient thyroid hormone and causes the hair to become dry, brittle and thin.
Hypoparathyroidism is a thyroid disease where the production of parathyroid hormone is too little causing the calcium blood levels to fall and phosphorus to increase and resulting in dry hair.
