This disorder is unpredictable, hair may start growing back at any time and it may start falling again. Currently, it is not possible to know when it may fall and when it may grow again.

Pattern Hair Loss

As we grow old, some follicles stop producing hair. This is referred to as hereditary hair loss, it is also known as androgenetic alopecia. This type of hair loss is usually permanent, which means that hair will not grow back again.

Follicles itself shrivels up and is incapable of regrowing hair. However, you can slow down the hair fall process with an oral treatment called finasteride (Propecia) or a topical treatment called minoxidil (Rogaine). Men hair loss rate is faster than that of the female. Men may get bald in the result of hair loss, but, when it comes to female, hair becomes rough and thin. It rarely reaches to baldness.

Scalp Psoriasis

Psoriasis is an autoimmune disease, which causes scaly red patches (plaque) on the scalp. It causes temporary hair loss. If you are scratching the scalp in order to relieve itching or removing the scales it may worsen the hair loss problem. Once you get proper treatment and stop scratching your scalp, your hair will start growing again.

Thyroid Disorder

Hair loss can also be caused due to thyroid disorder. The thyroid can be of two types:

  • Hyperthyroidism: It causes too much thyroid hormones
  • Hypothyroidism: It causes too little thyroid hormones

Once, you start taking proper medication for thyroid, your hair will start growing again.
