What is hair loss in women?
Most women shed between 50 and 100 strands of hair a day as part of the normal hair growth cycle. As old hairs fall out, new ones take their place. Hair loss is what happens when that balance breaks down: once daily shedding regularly climbs past roughly 100-125 hairs, or new growth stops keeping pace, thinning becomes noticeable.
Women experience three main types of hair loss:
- Androgenetic alopecia (female pattern hair loss): gradual thinning at the crown and sides, often with a widening part line.
- Telogen effluvium: more hair follicles than usual enter the resting (telogen) phase, causing increased shedding.
- Anagen effluvium: triggered by medications or treatments that damage active hair follicles directly.
7 ways to prevent hair loss in women
If you want the short version, here's what dermatologists and hair-loss specialists most often recommend:
- Manage chronic stress with regular exercise, sleep, or therapy.
- Treat underlying conditions like thyroid imbalances or nutrient deficiencies.
- Eat a nutrient-rich diet and avoid rapid or extreme weight loss.
- Cut back on heat styling, tight hairstyles, and harsh chemical treatments.
- Protect your scalp from sun damage.
- Ask your doctor about medications like minoxidil, or hormone-related options if appropriate.
- Consider FDA-cleared Low-Level Light Therapy (LLLT) to stimulate dormant follicles non-invasively.
Each is covered in more detail below.
What are the symptoms of hair loss in women?
Symptoms vary, but the most common early sign is noticing more hair falling out than usual on a daily basis. For instance, visible patches of thinning hair, particularly where the part on top of your head starts to widen.
Another telltale sign is when your scalp becomes more visible through your hair. Ponytails often become noticeably thinner, and hair may feel more brittle, with strands breaking more easily than before.
When should you see a doctor about hair loss?
While some daily shedding is completely normal, excessive shedding, a widening part line, sudden thinning, bald spots, scalp irritation, or rapid changes in hair texture may indicate an underlying issue that needs medical attention.
Hair loss accompanied by fatigue, weight changes, irregular menstrual cycles, or skin changes can also point to hormonal imbalances or nutritional deficiencies. Seeking professional evaluation early improves the odds of successful treatment.
What causes hair loss in women?
There are several causes of hair loss in women, including:
- Damaged hair follicles: often from overheating hair with curling and straightening irons or hair dryers, which weakens strands.
- Changes in eating habits: Rapid weight loss or restrictive diets can deprive your body of nutrients that support hair growth.
- Stress: High levels of chronic stress can disrupt the natural hair growth cycle, leading to increased shedding.
- Chemical hair treatments: Overuse of coloring (toning), straightening, or perming can damage hair follicles and cause thinning.
- Medical treatments: Chemotherapy and radiation therapy can cause significant hair loss due to their effects on active hair follicles.
- Underlying health conditions: Issues like an abnormal thyroid or a vitamin D deficiency can lead to hair thinning or loss.
- Hormonal changes: Major life events such as pregnancy, post-pregnancy, or menopause can shift hormone levels enough to affect hair growth.
- Medications and supplements: Certain prescriptions, like heart disease medicines and antidepressants, can contribute to hair loss.
- Genetic predisposition: A family history of hair loss increases the likelihood of experiencing it yourself.
How is hair loss in women treated?
Most effective treatment plans combine more than one of the following approaches. This is general information, not medical advice. A dermatologist or your doctor can confirm what's right for you:
- Reducing stress: Regular exercise and therapy can help prevent further hair loss.
- Managing underlying health conditions: Treating issues such as thyroid disorders or nutrient deficiencies addresses the root cause.
- Avoiding harmful hair products: Steering clear of harsh styling products and shampoos containing harmful ingredients helps strengthen follicles.
- Maintaining a healthy diet: A diet rich in essential nutrients supports hair growth and overall health.
- Limiting sun exposure: Protecting your scalp from sunburn helps prevent further thinning.
- Changing your hairstyling routine: Avoid heat styling and tight hairstyles that pull on hair and cause traction alopecia.
- Topical or oral medication: Minoxidil (Rogaine®) is effective for many women. Finasteride (Propecia®) should be avoided by anyone pregnant or planning to become pregnant. Some doctors also prescribe spironolactone, an anti-androgen medication used off-label for female pattern hair loss.
- Hormone therapy: Birth control pills or hormone replacement therapy can help regulate hormones contributing to hair loss.
- Quitting smoking: Stopping smoking improves hair health and decreases the risk of thinning.
- Low-Level Light Therapy: LLLT can stimulate hair growth while enhancing the effects of other treatments. This is one reason more women are turning to LPT.

Figuring out your hair loss
The right next step depends on a few specifics of what you're experiencing:
- How long has it been going on? Shedding that started in the last 2-3 months and follows a stressful event is often telogen effluvium, which usually resolves on its own once the trigger passes.
- Is it all over, or in one spot? Diffuse thinning across the whole scalp points toward pattern hair loss or a systemic cause (thyroid, nutrition, hormones). Thinning concentrated in one patch is more often traction alopecia or a localized scalp condition.
- Any recent major stressors, physical or emotional? Illness, surgery, childbirth, significant weight loss, or emotional stress are the most common triggers for temporary shedding, and identifying one can point straight to the fix.
If your shedding has lasted more than a few months, is worsening, or you're unsure which pattern fits, a dermatologist can confirm the cause. In the meantime, an FDA-cleared LLLT device is one of the few options considered safe to start regardless of the underlying cause, while you get a diagnosis.
Can hair loss in women be reversed?
In many cases, female hair loss can be slowed, stabilized, or partially reversed depending on the underlying cause. Conditions such as telogen effluvium, nutritional deficiencies, stress-related shedding, and some hormonal imbalances often improve once the trigger is addressed.
However, hereditary conditions like female pattern hair loss may require long-term management to maintain results. Early intervention typically offers the best chance of preserving hair density and encouraging regrowth.
How Theradome helps prevent hair loss in women
