Women's Hair Loss Is Diagnosed Before It Is Treated

In women there is a genuinely wide list of causes, and they are treated very differently. The common ones are iron deficiency, thyroid disease, hormonal conditions including PCOS, the shedding that follows pregnancy, significant illness, surgery, rapid weight loss or severe stress, certain medications, and female pattern hair loss. Several of these are fully reversible once identified, which is why diagnosis comes before treatment.

Shedding is losing noticeably more hair than usual — on the pillow, in the shower, in a brush — usually over a defined period. Thinning is a reduction in the density and calibre of the hair that remains, so a parting widens or a ponytail feels smaller. They have different causes and the distinction is one of the first things established at examination.

A temporary disturbance of the hair cycle in which an unusually large number of hairs shift into the shedding phase at once. It classically follows childbirth, serious illness, surgery, a crash diet or a period of severe stress, and it typically appears some months after the trigger. It usually recovers on its own once the cause is addressed, which is why treating it patiently is more useful than treating it aggressively.

It depends on your history and examination. Investigation of iron stores and thyroid function comes up frequently. Hormonal tests are ordered where the history points that way, and other bloods are added where indicated. The purpose is to find anything reversible, because treating that is far more effective than working around it.

Low iron stores are a recognised contributor to hair shedding in women and are common, particularly with heavy periods, restricted diets or pregnancy. It is one of the most worthwhile things to check, because correcting it is straightforward and the hair often follows. It should be assessed properly rather than self-treated with supplements.

Polycystic ovary syndrome can be associated with hair thinning in a pattern distribution, often alongside other features. If your history suggests it, that is investigated and managed as a condition in its own right, because treating the hair while the underlying picture is uncontrolled is treating a symptom.

Post-partum shedding is common and usually temporary, typically starting some months after delivery and recovering over the following months. The most useful things during that period are patience, checking for anything else contributing such as low iron or thyroid change, and avoiding aggressive treatment for something that is resolving on its own.

Depending on the diagnosis: correcting a deficiency, treating a thyroid or hormonal condition, topical treatment, prescribed medication where appropriate, supportive treatments such as PRP, and adjusting hair practices where traction is a factor. What suits you is decided after the diagnosis, not before it.

Because prescribing is individual, some of the relevant medicines are not safe in pregnancy or when trying to conceive, and publishing a regimen invites people to self-medicate without a diagnosis. What you should be taking, if anything, is decided in consultation where your history can actually be taken into account.

Hair is slow. Reduced shedding is usually the earliest sign and can take some weeks to months. Visible improvement in density is assessed over several months against baseline photographs. Judging progress in a mirror week to week mostly measures the lighting in your bathroom.

Most women who ask this question do not. Surgery relies on a stable donor area, and female thinning is frequently diffuse and often involves the donor too. Where it genuinely fits — traction alopecia, a high or receding hairline, scarring, or localised loss with a stable donor — it works well. See hair transplant for women.

Yes. Sustained tension from tight braids, extensions, weaves or tightly pulled styles can permanently destroy follicles, typically along the hairline and temples. Caught early it can improve once the tension stops. Left long enough it does not come back, and grafting becomes the only option.

They correct a deficiency if you have one, and do very little if you do not. Taking supplements without knowing your iron, thyroid or vitamin status is guessing, and some things are harmful in excess. Test first.

A list of every medicine and supplement you take, any recent blood results, photographs showing how your hair looked before, and the dates — when the loss started and what else was happening around then. That timeline is often the most diagnostically useful thing you bring.
