Minoxidil against hair loss

Minoxidil is an approved drug used to stimulate hair growth in various types of hair loss. It is available as solution, foam and in some cases as tablet form (oral minoxidil). The product is best known for its effect in androgenic alopecia (hereditary hair loss), but is also used in other conditions where you want to promote the growth of new hair.

about minoxidil

How does minoxidil work on hair?

Minoxidil is an over-the-counter drug used to treat hereditary hair loss in both men and women. It works by increasing blood circulation in the scalp, which stimulates the hair follicles and can lead to new hair growth. Most users see results after 3—6 months of daily application.

When minoxidil is applied to the scalp, it affects the blood vessels by dilating them locally. It leads to improved blood circulation around the hair follicles, which in turn provides a better supply of oxygen and nutrients. This increase in blood flow can stimulate dormant hair follicles and prolong the growth phase of the hair (the so-called anagen phase).
The result is often that the hairs grow stronger, thicker and, in some cases, that new hairs begin to form.

Minoxidil for hair does not work by “starting” hair where there are no longer active hair follicles, but can have very good effect if the hair follicles are still alive but weakened.

Results with minoxidil

How long does it take for minoxidil to work?

Minoxidil gives visible results against hair loss after about 2—6 months, with maximum effect after 12 months with daily use. For best results, treatment must be done consistently every day. If the use is discontinued, the effect ceases within a few months, and the hair loss can gradually return to its original state.

It takes a certain amount of time before you see a clear result of minoxidil against hair loss, because hair growth is a slow and individual process. To get visible results with minoxidil, regular use is required — twice a day, often for at least two to three months. Patience and continuity are essential for treatment to be effective. The result may vary depending on the cause of the hair loss, age and how early treatment is started. In case of uncertainty, consultation with a health professional can be helpful to ensure the right treatment.

How to maximize the result with minoxidil

Minoxidil is a clinically tested substance that stimulates hair growth by dilating the blood vessels of the scalp, improving the supply of oxygen and nutrients to the hair follicles. The product is used to slow hair loss and can provide visible results within 2—6 months.

For maximum results with Minoxidil, the drug must be taken every day. If treatment is discontinued, the effect will cease within 3-4 months, and hair loss will return.

Are the results of minoxidil permanent?

The results of minoxidil are not permanent. To maintain minoxidil results, continuous use is required. If treatment is discontinued, hair growth will gradually return to the state it was in before use.

side effects

What side effects can minoxidil cause?

Common side effects of minoxidil are itching, redness, dry scalp, and hair follicle inflammation. Rare but more serious side effects include palpitations, chest pain, low blood pressure, dizziness, and allergic reactions such as contact dermatitis. In the event of severe symptoms, treatment should be discontinued and a doctor should be contacted.

When used correctly, the side effects of minoxidil are usually mild and temporary. In contrast, oral minoxidil is not approved in Sweden for the treatment of hair loss, as the systemic form can produce more serious side effects that affect blood pressure. If you have concerns about safety or wonder if minoxidil works for you, you should always consult a specialist.

combine PRP & Minoxidil against hair loss

We often recommend a combination of PRP and Minoxidil against hair loss as an effective method. Minoxidil works by stimulating blood flow to the hair follicles, which in turn can improve the hair's ability to grow.

PRP, which contains the body's own growth factors, is injected into the scalp and activates the stem cells around the hair follicles. The result is often that the hair follicle is enlarged and that dormant hair begins to grow again. Both PRP and minoxidil reduced hair loss and positively affect the hair follicle, allowing combination treatments to produce improved results.

Minoxidil can also stimulate beard growth and give a fuller result over time. PRP is injected into the skin and activates the hair follicles with the body's own growth factors. The combination can give a better effect because both strengthen the hair follicle and can reduce hair loss.

Questions and answers

Here you can see the most frequently asked questions about minoxidil.

How long does it take for minoxidil to work?

Visa mer

It usually takes between 3 and 6 months before you start to see visible results of minoxidil. Since hair growth is a slow biological process, patience and consistent use are required — the treatment is applied twice daily to achieve the best effect.

Is Minoxidil dangerous?

Visa mer

Minoxidil does not have any known serious side effects.

The main side effect of using Minoxidil is that it can cause an increase in blood pressure. If you already have high blood pressure, we advise against the use of the preparation.

What happens when you stop using Minoxidil?

Visa mer

Just like with PRP Treatments so you need to continue with Minoxidil treatments continuously for the best possible results.

If you stop using Minoxidil, the increased hair growth you received from the medication may fall off within 3-4 months and you will return to the hair growth you had before treatment.

What if a woman uses 5% minoxidil?

Visa mer

Rogaine for women

5% minoxidil may provide better effects for some women, but the risk of side effects increases — such as scalp irritation or unwanted hair growth on the face. For many women, 2% minoxidil is enough, which is the recommended first choice and usually best adapted for women.
