If you've read our other articles in this series, you'll already know that hair loss has many possible causes and that treatment options exist for most of them. What we haven't covered yet is a thread that runs through several of those causes: hormones, and specifically how a handful of distinct hormonal life events, not just one, can each independently trigger or worsen hair thinning.
Perimenopause and menopause are the most commonly discussed of these, but starting, switching or stopping hormonal contraception can have a similar effect, and often catches women by surprise because it isn't widely talked about. This article looks specifically at these hormonal turning points: what tends to happen, why, and what's worth mentioning to a clinician if you think one of them applies to you.
Our article on the causes of female hair loss covers the full picture, but the short version relevant here is this: oestrogen tends to prolong the hair growth phase, while androgens, hormones including testosterone, can shorten it and gradually shrink genetically susceptible follicles. Most day-to-day hair health depends on the balance between the two, which is exactly why several distinct hormonal events, not just one, can each disturb that balance in their own way.
For many women, perimenopause and menopause are the first time hair thinning becomes noticeable, and there's a clear physiological reason why. As oestrogen levels decline through the menopausal transition, its protective effect on the hair growth cycle fades, while androgen levels stay relatively stable, shifting the overall balance towards shedding and, in genetically susceptible women, towards female pattern hair loss.(1)
This is why pattern hair loss so often seems to ‘appear’ around this life stage. In many cases, the genetic tendency was there all along; menopause is simply what reveals it, rather than what creates it from nothing.
Alongside pattern hair loss, some women notice a more general thinning and change in hair texture during the menopausal transition, related to wider hormonal and metabolic changes affecting the hair follicle at this time.(1)
The evidence on hormone replacement therapy (HRT) and hair is currently mixed. HRT is prescribed to manage a range of menopausal symptoms and may help some women's hair as a secondary effect of restoring oestrogen levels, but it isn't a licensed or reliable treatment for hair loss on its own, and shouldn't be started for that reason alone.(2)
If you're considering HRT, that conversation is best had on its own terms, factoring in the full range of menopausal symptoms, not just hair.
Hormonal contraception affects hair through two quite different mechanisms, depending on whether you're starting it, using it long-term, or stopping it.
Combined contraceptives contain a synthetic progestin alongside oestrogen, and progestins vary considerably in how androgenic they are; some behave more like testosterone in the body than others.
In women who are genetically predisposed to pattern hair loss, a higher-androgen progestin can unmask or worsen thinning, typically appearing as gradual, diffuse shedding while taking the contraceptive.(3)
Progestin-only methods, including the hormonal coil, can carry a similar risk. A review of a national medicines-monitoring database identified confirmed cases of hair loss among users of the levonorgestrel intrauterine device, alongside similar reports for other progestin-only methods.(4)
The reverse mechanism applies when you stop a combined method: oestrogen levels fall, and a proportion of hairs that had their normal shedding delayed are released together.
This tends to appear two to four months after stopping and is a form of telogen effluvium. It's temporary and usually resolves within six to twelve months, in the same way as the postpartum hair loss discussed in our first article.
If you notice hair changes that line up with starting, switching or stopping a hormonal contraceptive, it's worth mentioning both the timing and the specific product to whoever you speak to.
Switching to a lower-androgen formulation, or a non-hormonal method, is a reasonable option to discuss if a particular contraceptive seems to be contributing, though this is always a decision to make alongside your wider contraceptive needs, not hair alone.
Hormonal causes of hair loss are often identified through timing and history rather than a single test, so it's worth being ready to talk through:
This is exactly the kind of detail a prescriber will want alongside the physical examination and any blood tests discussed in our causes article, and it often speeds up getting to an accurate answer.
This article is focused specifically on hormonal life events, rather than repeating the wider list of causes, treatments or everyday coping strategies covered elsewhere in this series.

Together, these four articles are designed to answer the question wherever you're starting from.
The following questions are answered with reference to current clinical understanding. If you have specific concerns about your health, please speak to a qualified healthcare professional.
No. Not every woman notices hair changes during perimenopause or menopause, and how much it affects you varies considerably depending on genetics and other individual factors. When it does happen, it's usually a gradual thinning at the crown and parting rather than sudden hair loss.
The evidence is mixed. HRT may help some women's hair as a secondary effect of restoring oestrogen levels, but it isn't a licensed treatment for hair loss specifically, and shouldn't be started for that reason alone. It's worth discussing as part of a wider conversation about menopausal symptoms.
Yes, in some women, particularly those already predisposed to pattern hair loss. Certain progestins used in hormonal contraception are more androgenic than others and can unmask or worsen thinning. Switching to a lower-androgen formulation is sometimes an option worth discussing.
In most cases, yes. Hair loss after stopping a hormonal contraceptive is usually a temporary telogen effluvium, appearing two to four months after stopping, and typically resolves within six to twelve months as your hormones settle.
It can in some women, since it releases a progestin with androgenic properties. Reported cases are relatively uncommon, but it's worth mentioning to your prescriber if you notice hair thinning after having one fitted.
The timing of when you first noticed changes, relative to menopause or any changes to your contraception, plus any other symptoms you've noticed such as irregular periods or hot flushes. This detail, combined with an examination, usually points clearly to what's going on.
