Causes of Thinning Hair in Women

Disruption of the Cycle
There are things that interfere with hair’s growth cycle like chemicals, illness, and certain medications, among others; they can take a toll on your hair and stop it from being formed properly. Virtually anything that disrupts the cycle can most likely cause thinning hair and hair loss.

Hair loss may seem more common in men but women are nearly as likely to experience thinning hair. In fact, most women notice it in their late adulthood, although it can occur at any age and for several different reasons.
Normally, we shed 50–100 hairs per day and there are ways of knowing when hair is lost at a higher rate or is thinning. This becomes quite obvious when you comb your hair and an unusual number of hairs are left in the comb even without tugging and when there’s a large amount of hair on your pillow when you wake up in the morning. Women can also look for visual cues. While men’s hairline recedes and hair loss reaches the crown of the head, women generally notice thinning on the top of the head until it gradually involves a larger area. Most of the time, their frontal line remains intact

Genetic Predisposition
Thinning hair in women has a variety of causes that only a healthcare provider will be able to determine. Some blood work may be done to ensure that there is no thyroid disorder or an autoimmune disease. A brief history of the patient is also taken to establish the involvement of genetic predisposition. Scalp magnification is also done to check if the patient’s hair follicles vary in size—with some thin and others thick. These are telltale signs of androgenetic alopecia or female pattern baldness, a hereditary condition that affects around 30 million American women.

Female pattern hair loss is the most common kind of hair loss that occurs in about 50 percent of women. Women who are in their late 50s or 60s have the highest incidence rate, although it can happen anytime, even during puberty. On average, a normal follicle that sheds is being replaced by one that is equal in size. But in women with female pattern hair loss, the new hair shafts that replace the shed shafts are thinner and finer. The follicles miniaturize or shrink until these stop growing hair altogether.

Medical Conditions
Thinning Hair can be caused by a certain illness or a medical condition. If the hair loss is sudden or if the follicles are uniform in size, thinning of hair may be due to thyroid disorders, polycystic ovarian syndrome (PCOS), anemia, autoimmune diseases or skin conditions like seborrheic dermatitis and psoriasis.
Perimenopause
The link between thinning hair and perimenopause is established in that during menopause, estrogen levels decrease and the body starts to produce the 5-alpha reductase enzyme which works on the small amount of testosterone to convert it to DHT. This leads to thinning hair more often around the temples and on the crown yet doesn’t usually end in hairless patches.
Stress and Other Conditions
Stress, physical trauma, and dramatic weight loss may also cause thinning hair or hair loss. Hair starts to shed a few weeks to six months following any of these experiences.

Tight hairstyles like cornrows, pigtails, or tight braids can also cause a kind of thinning hair called traction alopecia. The application of chemicals from hair dyes and treatment products as well as frequent use of flat irons, blow dryers, and bad brushes can lead to hair damage and breakage.
Fortunately most of these conditions are reversible and the sooner the treatment is started, the better your chances of stopping further loss and regrowing your hair.
