16 Surprising Reasons Your Hair Is Falling Out

You have a hormonal disorder

hair loss problemPhimsri/ShutterstockWhen women have a hormonal disorder that causes high levels of testosterone, including polycystic ovary syndrome (PCOS), they may experience thinning of hair on the scalp. Often these conditions are also associated with acne, irregular periods, and hair growth in areas typically seen in men, says Joshua Zeichner, MD, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. “Over-the-counter supplements, such as Nutrafol, can help provide the follicles with the necessary building blocks for healthy hair production,” he says. These are other sneaky reasons your hair is thinning.

You just had a baby

Loving mother hand holding cute sleeping newborn baby childHTeam/ShutterstockWhile pregnant, many women notice that their mane becomes thicker, fuller, and shinier, thanks to a surge of pregnancy hormones. However, once they deliver, this flood of hormones leaves their body at a rapid pace, often leaving them with little time to adjust. One side effect of this depletion of hormones is hair loss. Thankfully, for many women, their hair goes back to normal a few months postpartum. Check out these other surprising ways you look different when you’re pregnant.

It’s in your genes

 

Closeup of a pile of vintage family photosKarin Hildebrand Lau/ShutterstockJust like with your hair color and hairline, your genes often determine whether you’ll experience thinning hair. It’s a myth that you inherit your hair loss gene from your mother’s father, says Dr. Zeichner. “There are many genetic causes. Women tend to develop a widening of their part line and thinning of hair on the top of the head, but typically do not fully lose their hair in the way that men do.” Quit falling for these 17 hair myths that ruin your tresses.

You’re taking birth control pills

Birth control pill / contraceptive / safe sexsuriyachan/ShutterstockJust like pregnancy, birth control pills mess with your hormone levels, causing them to fluctuate. In response, you might experience hair loss. “Hormones can interrupt the natural pattern of the hair cycle, causing hairs to shed more quickly than usual or to grow with less vigor,” explains Dominic Burg, PhD, chief scientist for Advangen. Oftentimes the hormone responsible for this is an androgen, such as testosterone, which is why the American Hair Loss Association recommends low-androgen birth control pills for those who are at an increased risk for hair loss.

Your diet

You’re super stressed

Here’s how to repair damaged hair with items you already own.

You have an underlying illness

Changes in these features provide some clues about the length and severity of illness.” Other diseases, such as diabetes and lupus, can also cause hair loss. Check out these other things your hair can reveal about your health.

You’re taking certain medications

One frequent culprit is anti-acne medications, specifically those that involve types of retinol (vitamin A),” explains Burg. “There are also reports of some anti-aging creams containing retinols causing hair loss.” It is unclear how these medications interfere with hair growth, but disruption of the hair cycle is a common issue, he adds.

Your hairstyle

Strong fitness woman tying ponytail.F8 studio/ShutterstockHow you wear your hair on a daily basis may influence how healthy it is. “Wearing a tight ponytail, braid, or extensions may, over time, put stress on the hair follicle and lead to hair shedding and permanent loss,” says Dr. Zeichner. He recommends wearing looser styles or wearing your hair down as much as possible. Check out these miracle-working hair products every woman needs.

You over-process your strands

For example, harsh chemicals for bleaching and straightening, along with excess heat, can damage and even kill hair follicles, Burg points out. Additionally, excessive chemical treatments applied directly on the scalp can cause inflammation. “Inflammation can damage the follicle, which in turn to can lead to hair loss,” says Maria Halasz, CEO of évolis Professional. To prevent over-processing, she recommends limiting chemical treatments on the scalp to every four to six weeks. Check out these tips for people who use heat on their hair every day.

You over-use hot tools

James warns that setting your tools to 450ºF or higher or keeping your hair on the hot tool for too long can burn your hair and potentially cause it to break off. “Set your flat iron or curling iron on medium heat and work with smaller sections, which require less time on the hot tool.” To ease yourself off, try these ways you can curl your hair without a curling iron.

You have trichotillomania

Find out why you shouldn’t pull out gray hairs either.

You overuse dry shampoo

cropped image of hairdresser applying hair spray LightField Studios/ShutterstockIt’s become “trendy” to not wash your hair for several days; in fact, some believe it’s beneficial for the hair. While you shouldn’t over-wash your hair, under-washing—washing your hair once or twice a week—and camouflaging dirt and grime with dry shampoos isn’t good for your hair either. “Overuse of dry shampoos leads to clogged follicles, which, over time, can cause permanent damage leading to hair loss,” warns Halasz. “To prevent this from happening, try to wash your hair a minimum of every three to four days.” Learn all the tricks you need to know when using dry shampoo.

You constantly wear hats

You’re iron deficient

You’re not protecting hair from sun
