What causes hair loss?

It's true that men are more likely to lose their hair than women, but thinning hair and hair loss actually affects both sexes—and it's no more or less demoralizing for either. But here's the thing: There's no one reason behind hair loss—causes can range from the simple and temporary (like a vitamin deficiency) to the more complex, like an underlying health condition.

Luckily, there are also many ways to treat hair loss in both women and men (cause-dependent, of course) Here are some common and not-so-common reasons why you might be seeing less hair on your head—and what you can do about it.

1-You're super stressed out. 수퍼 스트레스

Alopecia is an umbrella term for many types of hair loss. Watch the video to learn what exactly alopecia is.

2. You're pregnant. 임신

Pregnancy is one example of the type of physical stress that can cause hair loss (that and hormones). Pregnancy-related hair loss is seen more commonly after your baby has been delivered rather than actually during pregnancy. “Giving birth is pretty traumatic,” says Dr. Glashofer.

If you do experience hair loss after pregnancy, rest assured that your hair will grow back in a couple of months. “It’s a normal thing and it will work its way out,” Dr. Glashofer says.

3. You're getting too much vitamin A 비타민 A 과다섭취

•Overdoing vitamin A-containing supplements or medications can trigger hair loss, according to the American Academy of Dermatology. Just FYI: The Daily Value for vitamin A is 5,000 International Units (IU) per day for adults and kids over age 4; supplements can contain 2,500 to 10,000 IU. So any more than that and you could risk some strands falling out.

•The good news: This is also a reversible cause of hair loss, and once the excess vitamin A is halted, hair should start growing normally again.

4. You're not eating enough protein. protein 섭취 부족

You consume plenty of protein by eating meat and eggs, but you can also get protein in an array of other foods, all of which are meat-free. Watch this video for some surprising sources of protein.

5. You have female– or male–pattern baldness. 태생적 대머리

You might already know about male–pattern baldness, a type of hair loss caused by a combo of genes and male sex hormones that usually makes the hair on a man's head recede at the temples, leaving an M–shaped hairline.

But hormone-related hairloss for females—or female–pattern baldness—is also a thing, according to the US National Institute of Health. This type of hair

6. Your mom lost her hair, too. 어머니가 머리털이 없는 경우

“If you come from a family where women started to have hair loss at a certain age, then you might be more prone to it,” says Dr. Glashofer. Unlike men, women don't tend to have a receding hairline, instead their part may widen and they may have noticeable thinning of hair. This is also known as female–pattern baldness.

Women may benefit from minoxidil (Rogaine) to help grow hair, or at least, maintain the hair you have, Dr. Glashofer says. Rogaine is available over-the-counter and is approved for women with this type of hair loss

7. Your hormones are changing. 호르몬이 변화

Just as pregnancy hormone changes can cause hair loss, so can switching or going off birth-control pills. This can also cause telogen effluvium, and it may be more likely if you have a family history of hair loss. The change in the hormonal balance that occurs at menopause may also have the same result. “The androgen (male hormone) receptors on the scalp becoming activated,” explains Mark Hammonds, MD, a dermatologist with Scott & White Clinic in Round Rock, Texas. “The hair follicles will miniaturize and then you start to lose more hair.”

What to do: If a new Rx is a problem, switch back or talk to your doctor about other birth control types. Stopping oral contraceptives can also sometimes cause hair loss, but this is temporary, says Dr. Hammonds

8. Your emotions are at an all-time high. 항상 감정 고조.

Help yourself relax almost anywhere

9. You're anemic. 빈혈증세

Getting enough iron in your diet can be tough.

10. You have hypothyroidism. 갑상선기능저하

Your thyroid—a small gland in your neck—has a huge impact on your body. It produces thyroid hormone (TH), which is responsible for keeping your metabolism, heartbeat, temperature, mood, and more, in check. An underactive thyroid doesn't produce enough TH, and that can cause a host of health problems. Watch the video for the warning signs

11. You have a vitamin B deficiency. 비타민 B 부족

Vitamin B12 helps your body produce DNA and red blood cells, supports your immune system, and encourages healthy nerve function. Watch the video to learn which foods are high in this essential nutrient.

12. You have alopecia areata. 탈모증

Alopecia is an umbrella term for many types of hair loss. Watch the video to learn what exactly alopecia

13. You have lupus. 피부결핵

To get a better sense of lupus, watch this video to learn more about the condition, and whether or not you or a loved one may have it.

14. You lost a lot of weight very quickly. 급격한 체중감량

•Sudden weight loss is a form of physical trauma that can result in thinning hair. This could happen even if the weight loss is ultimately good for you. It’s possible that the weight loss itself put unnecessary stress your body, or that not eating right can resulted in vitamin or mineral deficiencies. Loss of hair along with noticeable weight loss may also be a sign of an eating disorder such as anorexia or bulimia.

•This type of hair loss, too, will correct itself once after a while. "Sudden weight loss seems to shock the system and you’ll have a six-month period of hair loss and then it corrects itself,” says Dr. Hammonds.

15. You're undergoing chemotherapy. 화학요법 치료시

•Some of the drugs used to beat back cancer unfortunately can also cause your hair to fall out. “Chemotherapy is like a nuclear bomb,” says Dr. Glashofer. “It destroys rapidly dividing cells. That means cancer cells, but also rapidly dividing cells like hair.”

•Once chemotherapy is stopped, your hair will grow back although often it will come back with a different texture (perhaps curly when before it was straight) or a different color. Researchers are working on more targeted drugs to treat cancer, ones that would bypass this and other side effects. Luckily, there are a few ways to deal with hair loss during chemotherapy, like shaving it or covering it up with a scarf.

16. You have polycystic ovary syndrome. 다양성 난소 증후군

•Polycystic ovary syndrome (PCOS) is another imbalance in male and female sex hormones. An excess of androgens can lead to ovarian cysts, weight gain, a higher risk of diabetes, changes in your menstrual period, infertility, as well as hair thinning. Because male hormones are overrepresented in PCOS, women may also experience more hair on the face and body.

•Treating PCOS can correct the hormone imbalance and help reverse some of these changes. Treatments include diet, exercise, and potentially birth control pills, as well as specific treatment to address infertility or diabetes risk.

17. Your medication is to blame. 과다한 의료요법--혈압약 등

•Certain other classes of medication may promote hair loss. More common among them are certain blood thinners and the blood-pressure drugs known as beta-blockers. Other drugs that might cause hair loss include methotrexate (used to treat rheumatic conditions and some skin conditions), lithium (for bipolar disorder), nonsteroidal anti-inflammatory drugs (NSAIDs) including ibuprofen, and possibly antidepressants.

•If your doctor determines that one or more of your medications is causing hair loss, talk with him or her about either lowering the dose or switching to another medicine.

18. You're styling your hair a little too much. -과다한 모발처리

Vigorous styling and hair treatments over the years can cause your hair to fall out. Examples of extreme styling include tight braids, hair weaves or corn rows as well as chemical relaxers to straighten your hair, hot-oil treatments or any kind of harsh chemical or high heat. Because these practices can actually affect the hair root, your hair might not grow back.

In addition to avoiding these styles and treatments, the American Academy of Dermatology recommends using conditioner after every shampoo, letting your hair air dry, limiting the amount of time the curling iron comes in contact with your hair and using heat-driven products no more than once a week.

19. You're compulsively pulling your hair out. 습관성 머리 뽑기

Trichotillomania, classified as an “impulse control disorder,” causes people to compulsively pull their hair out. “It’s sort of like a tic, the person is constantly playing and pulling their hair,” says Dr. Glashofer says. Unfortunately, this constant playing and pulling can actually strip your head of its natural protection: hair. Trichotillomania often begins before the age of 17 and is four times as common in women as in men.

Some antidepressants may be effective, but behavioral modification therapy is another option.

20. You're just getting older. 나이들면

their 50s and 60s, says Dr. Glashofer. Experts aren’t sure why this happens.

Experts don't recommend that this condition be treated, says Dr. Hammonds. That leaves women with cosmetic approaches such as scarves, wigs and hair styled so as to cover up thin spots. That said, there are also plenty of tricks to prevent hair breakage and ways to keep your hair looking shiny and healthy in your 50s and above.

21. You're taking anabolic steroids. 호르몬제 과용

If you take anabolic steroids—the type abused by some athletes to bulk up muscle—you could lose your hair, according to the American Academy of Dermatology. Anabolic steroids can have the same impact on the body as polycystic ovary disease (PCOS), as the mechanism is the same, says Dr. Hammonds.
