Losing from about 50 to 100 hair strands a day is normal. But when too much is lost, say about 200 hair strands a day, then the question what causes hair loss becomes a topical one. Therefore, you should consider the following possible causes for you to be informed.
Most often, hair loss is hereditary. It may be by the genetics of both mother and father or either one of them that you inherited their baldness. You may also have relatives that are bald and that’s why you have excessive hair loss. This hereditary hair loss is called androgenetic alopecia.
People who don’t have enough iron or people who are anemic are likely to have excessive hair loss. This can be prevented by taking iron pills and foods that are good sources of iron such as pumpkin seeds, soybeans, white beans, spinach, oysters, clams and other organ meats.
Hormones somehow contribute as the biggest factor on hair loss causes. Hormones stimulate both hair shedding as well as hair growth. They may cause thinning through the head caused by a certain androgen called Dihydrotestosterone (DHT). When a person has a lot of androgen receptors in his/her hair follicles, DHT can attach to it causing more hair falling out.
A lot of women after giving birth to a child often wonder what causes hair loss in them. In two or three months after delivering a child, most women experience loss of hair after combing and stroking their hair. This can actually last up to six long months but will eventually return to its normal state. After a woman recovers from childbirth, positive hormonal changes usually occur in nearly all cases preventing hair from falling out further.
An overactive and underactive thyroid is one of the wide-spread causes of hair loss.
Taking some medications may have side effects of hair shedding too. Some of these drugs include medicines for arthritis, gout, Parkinson’s disease, blood pressure, heart problems, depression, blood thinner and many others.
Undergoing radiation treatment and chemotherapeutic medications will effect to hair loss too since it cause hair cells to stop from dividing. A few weeks after being treated, 90% of hair strands slowly become thin and easily break.
Major surgery or illness
Shedding of hair may occur after a body system’s shock due to major surgery or illness.
Fungus infection on the scalp
Infection such as ringworm which is a contagious fungal infection causes balding in most young children. Small patches with scaling like dandruffs are signs of a ringworm infection.
Stress, may it be mental or physical, is another factor that causes hair loss from about 3 months after the stressful event. Fortunately, this is only temporary. In most cases normal hair growth happens after recovering from stress.
Excess vitamin A
Too much vitamin A in the body can result in rapid hair shedding too.
Low protein intake
When a human body doesn’t get enough proteins that it needs, it allows hair to be in resting phase and prevents it from growing.
Some other causes include:
- Weight loss
- Severe flu and fever
- Vigorous grooming
- Eating disorders
- Hair cosmetics such as frequent bleaching, abusive use of gels, dyes, sprays and other cosmetic hair products.
- Hair styling such as blow drying, brushing and shampooing.
When you notice excessive loss of hair and you don’t know what to do, you might as well consult a hair specialist to attend to your needs, to figure out what causes hair loss and choose the appropriate treatment.
