What is the main cause of sudden hair loss?

Telogen effluvium is often caused by stress, which increases the natural rate of hair loss.


areata is an autoimmune condition that causes the body to attack hair follicles, causing hair loss. Alopecia areata is just one of many types of autoimmune diseases that can cause hair loss. Hashimoto's thyroiditis and lupus are two examples of other autoimmune diseases that can cause hair loss, according to DermNet NZ.

This type of hair loss isn't always reversible, sometimes it can be permanent. However, medications and hair restoration surgeries can help compensate for any hair loss. When you're faced with a life-altering event, such as a divorce or breakup, bankruptcy or other financial problems, the loss of a home, or the death of a loved one, significant emotional stress can disrupt the normal hair growth cycle. These physical traumas can include fungal skin infections, as well as bacterial infections such as syphilis, which may be responsible for baldness or hair thinning.

Treating the underlying infection can restore hair growth and prevent hair loss in the future, so the first step is to seek medical attention for the primary health problem. When the body is under severe physical stress, the natural cycle of hair growth and rest can be disrupted, causing hair loss, often in the form of thinning hair, and can even come out in bundles. Blood thinning medications, oral contraceptives, medications for depression, anti-inflammatory drugs, and beta and calcium channel blockers can cause hair thinning or baldness. Early treatment of hairline loss (frontal fibrosing alopecia) may help prevent significant permanent baldness.

While hair loss after delivery can't exactly be prevented, you can minimize the problem by taking it with care and keeping up to date with prenatal vitamins. An underactive thyroid (a medical condition called hypothyroidism) or an overactive thyroid (hyperthyroidism) can cause hair loss because each condition causes a hormonal imbalance. Whatever term you use, it means that you have inherited the genes that cause the hair follicles (from which each hair grows) to shrink and eventually stop hair growth. Poor diet or extreme or trendy diets that are very restrictive can cause all kinds of nutrient deficiencies, which in turn can cause hair loss, from weakening of the hair to areas of baldness.

Some chemotherapy drugs used to treat cancer are known to cause total hair loss by destroying cancer cells. While the most common cause of hair loss is an inherited condition called androgenic alopecia that occurs with aging, there can be many other common reasons behind the rapid thinning of the hairline. In addition, while Green recommends incorporating fatty fish, berries, green leafy vegetables and other foods that can promote healthy hair growth in the diet, he also points out that even a healthy diet can have its limitations. Some of them are excessive hair care, scalp infection, certain medications, or hormonal changes and chemical treatments on the hair.
