Alopecia is common among men and women at and even before the age of 21. Although there are different types of alopecia, when you talk about just alopecia, you are actually referring to alopecia areata.
It s an autoimmune hair loss disease in which your immune system gets misinformed and attacks your own body s cells, particularly those related to hair follicles. Your body considers hair follicles as foreign invaders, thus incorrectly attacking them.
This type of hair loss could be temporary and the hair could regrow after a few months. However, if the treatment is delayed or ignored, you could have permanent hair loss, resulting in bald patches on your scalp.
It could be hereditary or caused by external factors such as environmental conditions, stress, certain drugs or medications, infections, and viruses.
It s definitely treatable, provided your timing is right. For permanent hair loss, hair transplant through an experienced hair loss specialist is good enough. If the problem is temporary, you have many options like topical sensitizers, minoxidil, shampoos for sensitive scalps, anti-inflammatory medications, and much more.
