Estrogen and progesterone levels fall, meaning that the effects of the androgens, male hormones, are increased. During and after menopause, hair might become finer (thinner) because hair follicles shrink. Hair grows more slowly and falls out more easily in these cases.
With age, a woman's hair follicles don't create hair as quickly, meaning that growth slows down. Because hair falls out normally, there simply isn't enough hair production to replace it, leaving the hair on the head thin and sometimes patchy.
There are a wide range of conditions that can bring on hair loss, with some of the most common being pregnancy, thyroid disorders, and anemia. Others include autoimmune diseases, polycystic ovary syndrome (PCOS), and skin conditions such as psoriasis and seborrheic dermatitis, Rogers says.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.

The “gold standard” medical treatment for hair thinning is a drug applied to the scalp called minoxidil, widely known by the brand name Rogaine. The Food and Drug Administration has approved minoxidil for women as well as men, and you don't need a doctor's prescription to buy it.
Generally, people begin noticing signs of hair loss in their 30s and 40s. More significant hair loss often happens when people reach their 60s and beyond.
Alopecia areata is a disease that happens when the immune system attacks hair follicles and causes hair loss. Hair follicles are the structures in skin that form hair. While hair can be lost from any part of the body, alopecia areata usually affects the head and face.
Fatigue associated with an iron deficiency (or a lack of iron in the blood, with or without anemia) can cause chronic hair loss, scientifically referred to as “chronic telogen effluvium”.
If your dermatologist suspects that the cause of your hair loss could be a disease, vitamin deficiency, hormone imbalance, or infection, you may need a blood test or scalp biopsy. These tests can be done in your dermatologist's office.
The only medicine approved by the United States Food and Drug Administration (FDA) to treat female pattern baldness is minoxidil: It is applied to the scalp. For women, the 2% solution or 5% foam is recommended. Minoxidil may help hair grow in about 1 in 4 or 5 of women.
Finasteride and minoxidil are the main treatments for male pattern baldness. Minoxidil can also be used to treat female pattern baldness.
“In addition, there's no shampoo that's clinically proven to support hair regrowth.” “In addition, there's no shampoo that's clinically proven to support hair regrowth.” So, why do some people claim otherwise?

Here's the hard truth: Little can be done to permanently change the diameter of individual hair strands. Thickening products can do wonders to temporarily plump hair strands, but when it comes down to it, fine hair is genetic and can't be changed.
About 55 percent of women experience some hair loss by the age of 70. The most common cause is female-pattern baldness, an inherited condition. It's characterized by gradual thinning of your hair, which may be noticeable as a widening part or a ponytail that's less hefty than it used to be.
