According to Dr. Sarah Jarvis of Good Housekeeping, there are four main reasons for hair loss in women. The first is temporary hair loss due to stress, high fever, sudden weight loss, or major surgery. Hair typically grows back after a period of time.
Secondly, chemotherapy, radiation therapy, or exposure to heavy metals can cause patchy hair loss. This is an autoimmune disease where the immune system attacks hair follicles. Thirdly, hair loss can be caused by habits like tying hair too tightly.
The most common cause is age and hormonal changes. After age 65, about 50% of women experience this. Hair loss at the crown, causing a widening part, is often due to a combination of aging, genetics, and hormonal shifts.
"If you suddenly experience significant hair loss or hair falling out in clumps, see a doctor to check for underlying causes such as iron or vitamin D deficiency, thyroid issues, or polycystic ovary syndrome (PCOS)," advises Dr. Sarah Jarvis. She also recommends consulting a pharmacist about any medications you're taking, as some can contribute to hair loss.

Here are 5 scientifically-backed ways to prevent hair loss:
Minoxidil:
This is the only medically recommended treatment for women. It's available as a 2% solution or a 5% foam applied to the scalp. It can be very effective but requires continuous use. If discontinued, hair will revert to its original state within 3-6 months.
Vitamin D supplements:
Vitamin D deficiency has a clear link to female pattern hair loss. Supplementing up to 20 micrograms daily is safe and beneficial.
Zinc supplements:
Zinc supports hair follicles and hair growth. You can increase your zinc intake through foods like meat, nuts, whole grains, and legumes.
Rosemary oil:
Some small studies suggest rosemary oil can be as effective as minoxidil in increasing hair count. However, scientific evidence is still limited, and concentrated rosemary oil can irritate the skin.
Scalp massage:
Improving blood flow to the scalp can stimulate hair follicles. Some small studies have shown that daily scalp massage for six months improves hair growth.
