We lose an average of 100 hairs a day, however, these hairs are immediately replaced by new hairs growing at the same time. Hair loss can occur suddenly or gradually and it may affect your scalp or your entire body, depending on what’s causing it. Other causes of hair loss may include:
Stress - a lot of people may experience hair thinning for several months due to a physical or emotional shock. However, this type of hair loss is only temporary.
Certain Hairstyles and treatments - hairstyles that pull your hair like tight pigtails, ponytails or braids can actually cause traction alopecia. Permanent hair treatments and hot oil treatment may also lead to hair loss; these hair treatments cause inflammation to the hair follicles. If there is scarring, hair loss may be permanent.
Radiation Therapy - for example, during cancer treatment.
Certain medical conditions and hormonal changes - in women, hormonal changes due to pregnancy, childbirth menopause or thyroid problems may cause temporary or permanent hair loss. As for medical conditions, hair loss may be due to alopecia, scalp infections like ringworm or a hair-pulling disorder known as trichotillomania.
Sudden hair loss may also be a sign of a specific medical condition that will require treatment. You will need to consult your doctor if you experience more than your usual hair loss whenever you are combing or washing your hair and also if you encounter a sudden patchy loss of hair.
A hair transplant is a common treatment performed on people who are experiencing baldness due to aging and heredity factors. However, if you are completely bald with absolutely no hair left, then this type of treatment may not be applicable for you, as you won't have sufficient donor hair to supply.
