This is in both men and women. It is also increasingly being used to help with patchy beard growth. Minoxidil comes in topical form (a serum, foam or spray applied to the scalp or face) and as an oral tablet. This guide how minoxidil treats hair loss and why it does not work for . We also explore the difference between oral vs topical minoxidil, best way to use it, side effects and how to get it in the UK.

What is Minoxidil?

was originally developed in the late 1970s as an oral medicine for high blood pressure. Doctors noticed that patients taking it grew thicker hair. By got FDA approval for hair loss. It remains one of only a small number of hair loss treatments with solid evidence behind it. It is also the only topical treatment with formal for in both men and women.

The main way minoxidil works is by widening the blood vessels in the scalp and increasing blood flow to the hair follicles. This delivers more oxygen and nutrients to the follicle, and it is thought to prolong the anagen (growth) phase of the so that more hairs grow for longer. Although the exact mechanisms by which it works are still not fully understood, the effect is well established. With consistent use, minoxidil can reduce shedding and stimulate regrowth.

Despite its great potential, . The reason for this is that minoxidil is a pro-drug so it is not in its active form when you apply it. The skin has to convert it into its active form, minoxidil sulfate, using an enzyme called (SULT1A1) which is highly active in some people and less so in others. This conversion step and is the reason topical minoxidil works brilliantly for some people and barely at all for others. We will discuss this in more detail and options for poor responders below.

What Does Minoxidil Treat?

Broadly speaking, minoxidil is useful wherever the goal is to stimulate hair growth and prolong the growth phase of the follicle. As such it’s main uses are:

At City Skin Clinic, minoxidil is the active we use most often in our and treatments. We use it topically in custom compounded serums, alongside other actives where appropriate, designed around each person’s needs.

Minoxidil Strengths & Formulations

Higher strengths, compounded formulas and oral minoxidil are all used off-label or unlicensed and available by prescription-only. Minoxidil comes in three main forms. These differ in strength, how you take them and whether they need a prescription:

What Other Treatments Work Best with Minoxidil

stimulates hair growth but does not tackle the behind most pattern hair loss. This is why it is often compounded with other actives in a single serum or used alongside . The right combination depends on the person’s health, severity of hair loss and whether the target is the scalp or the beard. The actives most often combined with minoxidil are:

In addition to the above, can also help for both scalp and beard hair growth. It can potentially boost absorption of topical hair growth products as well as stimulates the follicles .

Why Doesn’t Minoxidil Work for Everyone?

Because topical minoxidil is a pro-drug, it is inactive when you apply it. The scalp has to convert it into its active form, minoxidil sulfate, using an enzyme called sulfotransferase (SULT1A1). However, the amount or activity of that enzyme in the hair follicle is genetic. People with high activity respond well. Those with low activity convert very little of the minoxidil they apply and so see little benefit even with diligent use. This is why only around on 5% topical . It also explains why two people with identical hair loss using the exact same treatment can get completely results.

For years there was no way to know in advance who would respond, so the standard approach was to commit to six months of daily use and see. This is beginning to change. A (sold as the Minoxidil Response Test) measures the enzyme’s activity in a few plucked hairs and can rule out non-responders before treatment. However, the test is not yet widely available in the UK as the evidence base is still small. If minoxidil is not working for you, there are several options worth considering:

How to Use Minoxidil

The way you use minoxidil depends on the form. Topical minoxidil, whether the over-the-counter has fairly standard instructions.

Whichever form you use, the timeline is the same. Most people get an in the first few weeks, which is normal and a sign the treatment is working as minoxidil pushes resting hairs into the growth phase. Early results follow at three to six months, with maximum results around nine to twelve months for scalp and beard alike. Minoxidil works only for as long as you use it, so the gains fade gradually if you stop.

Side Effects of Minoxidil

The side effect profile is very different between topical and oral minoxidil. This is one of the main reasons topical is more popular. Topical minoxidil, in both its over-the-counter and compounded forms. As absorption is only minimal, so its side effects are mostly local:

These apply to both topical strengths, although higher-strength compounded formulas can irritate more. Adjusting the strength or base usually this. Systemic effects are possible if a lot is the skin, but they are rare with topical use and far more relevant to the oral form.

Oral minoxidil works throughout the body, so it carries a wider set of risks. These are but are the reason it needs monitoring:

Although there’s a lower risk, it is worth noting that it is still possible to experience systemic even with topical formulas.
