It usually occurs gradually and in predictable patterns: a declining hairline and bald spots in men and slimming hair along the scalp crown in women. Hair loss is a side effect of various medications taken for common health problems. Anticoagulants, oral contraceptives, depression medications, NSAIDs and beta and calcium channel blockers can lead to thinning hair or baldness. Too many vitamin A and vitamin A based medications called retinoids can also cause hair loss. Some chemotherapy drugs used to treat cancer are known to cause total hair loss while working to destroy cancer cells. Just as the hair generally grows back after chemotherapy, it should also grow back as soon as you stop taking medications that cause hair loss.
Frontal fibration alopecia usually affects postmenopausal women. Certain medications can control symptoms and stop disease progression. In women, the hair slowly thins over the entire scalp, but the hairline generally does not deteriorate.
If you are taking certain medications or have cancer chemotherapy, you may also lose hair. Other causes are stress, a low protein diet, family history or poor nutrition. Alopecia areata, a common skin condition, generally starts as a single circle of a quarter of perfectly smooth bald skin. These patches generally grow back within three to six months without treatment. Sometimes white hair grows back temporarily and darkens. The most extensive form is alopecia totalis, with the entire scalp remaining bare.
Hair loss is considered exaggerated if it results in bare spots or thin hair. This is generally caused by sudden or prolonged stress, both physical and emotional. Poor nutrition or after a severely restrictive shock or fashion diet can lead to all kinds of nutrient deficiencies, which in turn can lead to hair loss, from thinning hair to bald spots. A 2007 study found M字額 that smoking can be a factor related to age-related hair loss in Asian men. The study followed age and family history and found statistically significant positive associations between moderate or severe hair loss in men and smoking. Frontal fibration alopecia is generally found in a pattern of hair regression and can also cause hair loss in the eyebrows and armpits.
This often happens about three months after the baby arrives. Don’t worry, while the rest of your body recovers, your hair follicles will too. Hair loss is only temporary: your hair grows back.
These conditions are diagnosed by blood tests along with historical and physical evidence. While some studies have suggested that baldness can be inherited by the mother’s family genes, these theories require further testing. Although not indicated for baldness of female patterns, spironolactone has had some success in treating this condition. Minoxidil is an approved freely available drug for male pattern baldness and alopecia areata. With a liquid or foam, it is rubbed on the scalp twice a day. Some people have an allergic reaction to propylene glycol in minoxidil solution and a minoxidil foam without propylene glycol has been developed.
The change in hormonal balance that occurs during menopause can also have the same result. “Androgen receptors on the scalp are activated,” explains Mark Hammonds, MD, dermatologist at the Scott & White Clinic in Round Rock, Texas. “The hair follicles are miniaturized and you lose more hair.”
Hair loss is often caused by genetics, that is, it occurs in families. In general, it is not a symptom of illness, but thyroid disease, anemia, ringworm of the scalp and anorexia can cause hair loss. Also, some medications such as cancer chemotherapy can cause temporary hair loss.
