Hair loss can be emotional. Whether you've noticed more hair in the shower, a widening parting or your ponytail feeling thinner than it used to, it can affect your confidence and leave you wondering what, if anything, you can do about it.
But it’s surprisingly common (affecting up to 50% of women), and there are hair loss treatments that can make a real difference. Minoxidil is one of the most talked-about developments in hair loss treatments for women.
Key Takeaways
- Oral minoxidil is a prescription-only, off-label treatment for female hair loss in the UK.
- Studies show oral minoxidil at low doses can improve hair density in many women with pattern hair loss.
- Results take time. Some women notice temporary shedding at first, with visible improvements typically appearing after three to six months of consistent use.
What are minoxidil tablets for women?
Minoxidil tablets—also known as oral minoxidil or low-dose oral minoxidil—contain the same active ingredient found in topical minoxidil treatments.
Minoxidil works by increasing blood flow to your hair roots. This encourages new hairs to grow. It also extends the growth phase of the hair cycle, slowing hair loss and allowing your hairs to grow longer.
With oral minoxidil, rather than applying minoxidil directly to the scalp, you simply take a tablet once a day.
Can women take minoxidil tablets for hair loss?
Yes. Oral minoxidil is increasingly being prescribed to women experiencing hair loss.
If you've tried shampoos, supplements or topical treatments without seeing the results you hoped for, oral minoxidil may be worth discussing with a clinician.
Minoxidil tablets are not currently licensed in the UK specifically for hair loss. Instead, they are prescribed "off-label". This means the medication is being used for a purpose outside its original licence.
Because oral minoxidil is a prescription-only medicine, you'll need to be assessed by a qualified clinician before starting treatment. This helps ensure the medication is safe for you and that any underlying causes of hair loss have been properly investigated.

Does oral minoxidil work for women?
The research on oral minoxidil for female hair loss is genuinely encouraging. Up to 80% of women experience thicker, fuller-looking hair and reduced shedding after several months of consistent treatment.
How long do minoxidil tablets take to work?
Oral minoxidil isn’t an overnight fix, but for women who stick with treatment, the results can be meaningful.
For women using minoxidil, results are generally seen after 4 to 6 months of treatment. Continued daily use is required to maintain these benefits.
Weeks 1 to 8: Temporary shedding
Seeing more hair fall out when you've started treatment can feel incredibly discouraging. However, temporary shedding is a recognised part of the process and doesn't mean the treatment isn't working. Minoxidil encourages hair follicles to move into a new growth cycle. As this happens, older hairs are shed to make way for new growth.
Months 2 to 4: Stabilisation
By this stage, shedding often begins to settle. Your hair follicles are responding to treatment, but visible changes may still be limited.
Months 4 to 6: Early results
This is when many women begin to notice positive changes. Hair may start to feel thicker, the scalp may become less visible and overall density may gradually improve.
Months 6 to 12: Full assessment
Most clinicians recommend assessing treatment success after 6 to 12 months of consistent use. At this point, you'll have a much clearer idea of whether the medication is working for you.
Side effects of minoxidil tablets for women
The reassuring news is that low-dose oral minoxidil is generally well tolerated, and most women who take it don't experience side effects severe enough to stop treatment.
Hypertrichosis (unwanted hair growth)
Hypertrichosis refers to increased hair growth in areas other than the scalp, such as the face, arms, or legs. Studies suggest that around one in five women experience some degree of unwanted hair growth while taking oral minoxidil.
In most cases, the hair growth is mild and manageable. Only a small proportion of women find it bothersome enough to stop treatment altogether.
Temporary shedding
As discussed earlier, temporary shedding during the first few weeks is common and usually settles without intervention.
Low blood pressure and dizziness
Because minoxidil was originally developed as a blood pressure medication, some women experience mild light-headedness or dizziness, particularly when standing up quickly. These symptoms are usually mild and can often be managed by staying hydrated and rising slowly from sitting or lying down.
Rare but serious side effects
Serious cardiovascular complications are extremely rare at the low doses used for hair loss. But the risk is one reason oral minoxidil should always be prescribed and monitored by an appropriately qualified clinician.
Can you buy minoxidil tablets in the UK?
Oral minoxidil is a prescription-only medicine in the UK, so you can't buy it over the counter, and it isn't routinely available on the NHS for hair loss treatment.
To access it, you'll need a consultation with a qualified clinician, either through a private GP, a specialist hair loss clinic, or a regulated online prescribing service. They'll assess whether oral minoxidil is suitable for you and provide any necessary monitoring and follow-up. You can see if it’s right for you by taking Voy’s hair quiz.
Although it can be tempting to look for quicker routes online, it's always safest to access oral minoxidil through a legitimate provider. That way, you can feel confident you're getting the right treatment, along with the medical support needed to use it safely.
