Hair Loss in Women: Causes and What You Can Do About It



Hair loss isn’t just something men deal with - many women experience it, too. In fact, by age 40, about 40% of women notice some thinning or hair loss. Whether it’s a little extra shedding or more significant thinning, it can be unsettling and impact confidence. The good news? Hair loss is often treatable, and understanding what’s behind it is the first step to tackling it head-on (no pun intended!).


Let’s dive into some of the most common reasons women experience hair loss and explore what can be done to get your hair back on track.


Common Causes of Hair Loss in Women


Hair loss in women happens for a variety of reasons, from genetics and hormones to lifestyle factors. Here are the most common culprits:


  1. Genetics and Female Pattern Hair Loss

Just like men, women can experience genetic hair loss. This condition, called female pattern baldness, is the most common cause of hair thinning in women. It’s often linked to the hormone DHT (a byproduct of testosterone) which can shrink hair follicles over time, leading to thinner hair, especially at the top of the scalp or along the part line. Unlike men, women typically don’t go completely bald, but the hair can become noticeably sparse.


  1. Hormonal Changes

Hormones can have a huge impact on your hair. For example, pregnancy can cause your hair to feel thick and lush, but after giving birth, many women notice significant shedding. This is called telogen effluvium, and it’s your body’s way of readjusting after the hormonal highs of pregnancy.


Similarly, as women approach menopause, a drop in oestrogen levels can trigger thinning hair. Hormonal fluctuations can also cause more hair to shed than usual, but the good news is this is often temporary and resolves once your hormone levels balance out.


  1. Stress

Ever notice more hair falling out when you’re stressed? You’re not imagining it. Emotional or physical stress - like recovering from surgery or dealing with a major life event - can send a shockwave through your body, pushing your hair into a resting phase. This condition, known as telogen effluvium, means you might notice more shedding a few months after the stressful event. The upside? This kind of hair loss is often temporary, and once the stress eases, your hair growth usually returns to normal.


  1. Poor Nutrition

Your diet affects more than just your waistline - your hair depends on it, too. If you’re not getting enough iron, protein, or certain vitamins (like vitamin D or B vitamins), you might notice your hair thinning. Iron-deficiency anaemia, in particular, is linked to hair loss because your hair follicles need oxygen-rich blood to thrive. So, if your iron levels are low, your hair might not get the nutrients it needs to stay strong and healthy.


  1. Thyroid Problems

Your thyroid gland controls a lot in your body, including your metabolism, energy levels, and even your hair growth. When your thyroid is either overactive (hyperthyroidism) or under-active (hypothyroidism), it can mess with your hair, causing it to thin or fall out. Luckily, once thyroid issues are diagnosed and treated, hair loss often improves.


  1. Alopecia Areata

This is an autoimmune condition where your immune system mistakenly attacks your hair follicles, leading to small, round bald patches. This type of hair loss, called alopecia areata, can happen suddenly and affect any part of the body, including your scalp, eyebrows, and eyelashes. It’s not fully understood what causes it, but it’s believed to be linked to genetics or environmental factors.


  1. Polycystic Ovary Syndrome (PCOS)

Women with PCOS often experience hair loss due to higher levels of androgens (male hormones), which can shrink hair follicles and lead to thinning. Hair loss associated with PCOS usually shows up as diffuse thinning, especially along the hairline, but other symptoms like irregular periods and weight gain can also help identify the condition.


  1. Hairstyling Habits

Sometimes, our hairstyling routines can lead to hair damage and loss. Frequently using heat styling tools, tight ponytails or braids, or undergoing chemical treatments like colouring or relaxing can weaken hair over time. This can result in traction alopecia, a type of hair loss caused by pulling on the hair. The damage is often reversible, but if done repeatedly, it can lead to permanent thinning.


Treatments for Hair Loss in Women


Now that we know the causes, what can be done about hair loss? The good news is that many treatments are available, and the sooner you address the issue, the better your chances of regaining thicker, fuller hair.


  1. Minoxidil (Rogaine)

One of the most effective and accessible treatments for hair loss in women is Minoxidil (commonly known as Rogaine). It’s an over-the-counter topical treatment that you apply directly to your scalp. Minoxidil helps to promote hair regrowth by stimulating the hair follicles. It’s particularly useful for female pattern hair loss and can increase hair density and thickness. Be patient - it can take a few months to see noticeable results, and you’ll need to keep using it to maintain regrowth.


  1. Oral Medications

In some cases, doctors may prescribe oral medications to help with hair loss. For example, spironolactone is a medication that blocks androgens (male hormones) and can be effective for women experiencing hormone-related hair loss. It’s often used for women with PCOS or those experiencing hair thinning due to excess androgens.


  1. Address Nutritional Deficiencies

If your hair loss is related to iron deficiency or a lack of other nutrients, addressing those deficiencies is key. Taking iron supplements or eating more iron-rich foods (like spinach, red meat, and beans) can help reverse hair loss caused by low iron. Similarly, ensuring you get enough vitamins like vitamin D, B vitamins (especially biotin), and protein in your diet will support hair health.


  1. Hormone Therapy

For women experiencing hair loss due to menopause or hormonal imbalances, hormone replacement therapy (HRT) or birth control pills can help regulate hormone levels and reduce hair thinning. It’s important to work with a healthcare provider to find the best option based on your specific hormone levels and symptoms.


  1. Platelet-Rich Plasma (PRP) Therapy

A newer, innovative treatment for hair loss is PRP therapy, which involves drawing a small amount of your blood, processing it to concentrate the platelets, and injecting that plasma into the scalp. Platelets contain growth factors that help stimulate hair regrowth. Though relatively new, PRP has shown promising results for some women with thinning hair.


  1. Hair Transplants

If other treatments haven’t worked, or if your hair loss is more advanced, hair transplant surgery might be an option. This involves moving hair follicles from areas where hair is still thick to areas where it’s thinning. While effective, it’s more invasive and expensive, so it’s generally considered a last resort.


  1. Healthy Hair Habits

Lastly, making small changes to your haircare routine can make a big difference. Avoid excessive heat styling, use gentler hair products, and give your scalp regular massages to improve circulation. If stress is a trigger for your hair loss, finding ways to manage stress through relaxation techniques, exercise, or therapy can help your overall health—including your hair.


Conclusion

Hair loss can be distressing, but it’s important to remember that it’s a common issue and often treatable. Whether it’s caused by genetics, hormones, or lifestyle factors, there are solutions that can help. By identifying the underlying cause of your hair loss and seeking appropriate treatments, you can take steps to regain healthy, thicker hair. The key is to act early and explore your options with the help of a healthcare provider who understands your specific needs.
