Question 1

How long does it take for minoxidil to work?

Accepted Answer

Plan for several months. The first visible changes usually appear after three to six months, and the result can often only be reliably assessed after six to twelve months of regular use. At the start, hair loss can temporarily increase. Taking stock after just a few weeks means judging too early.

Question 2

Spray or capsule, which is a better fit?

Accepted Answer

Minoxidil can be applied topically as a spray to the scalp or taken off-label as a capsule. The spray works locally where you apply it. The capsule works throughout the body, is prescription-only, and is used off-label at a low dose, for example when topical application does not help sufficiently or is difficult to fit into everyday life. What may be considered depends on your situation, how well you tolerate it, and your preference, and our doctors decide this together with you.

Question 3

Does minoxidil also help with a receding hairline at the temples and at the front of the hairline?

Accepted Answer

Minoxidil is best studied for the crown and vertex area at the top of the head. It can also have an effect at the front hairline and at the temples, though the effect there is often smaller. In areas that are already completely bald and where the hair roots are no longer active, minoxidil does not produce new hair.

Question 4

Can I combine minoxidil and finasteride?

Accepted Answer

Minoxidil and finasteride act at different points, minoxidil on the hair cycle and finasteride on the male hormone metabolism. That is why they are sometimes combined. Whether a combination makes sense in your case is decided by a doctor. Do not combine active ingredients on your own.

Question 5

What happens if I stop using minoxidil?

Accepted Answer

Minoxidil only works for as long as you use it. After you stop, the effect achieved fades over a few months, and hair loss continues to where it would be without treatment. It is best to discuss a planned discontinuation with a doctor.

Question 6

Is minoxidil available without a prescription?

Accepted Answer

Topical minoxidil for application to the scalp is approved in Germany for hereditary hair loss and is available without a prescription from the pharmacy. Oral minoxidil, the tablet, is not approved for hair loss, is only prescribed off-label, and is prescription-only.

Question 7

Why is minoxidil so dangerous for cats?

Accepted Answer

Cats are extremely sensitive to minoxidil. Even small amounts can cause severe heart and circulatory damage and be fatal. Store the product safely, wash your hands after applying it, and keep your pet away from treated skin, pillows, and towels. If you suspect contact, go to the vet immediately.

Question 8

How long does it take for finasteride to work?

Accepted Answer

Plan for several months. The first changes usually appear after three to six months, and the result can often only be reliably assessed after about twelve months of regular use. At the start, hair loss can temporarily increase. Taking stock after just a few weeks means judging too early.

Question 9

Finasteride or minoxidil, which is better?

Accepted Answer

The two active ingredients work at different points. Finasteride lowers DHT levels and thereby addresses the cause of hereditary hair loss. Minoxidil acts on the hair cycle and extends the growth phase. Which active ingredient, or whether a combination makes sense, depends on your situation and is something a doctor decides together with you.

Question 10

Finasteride and trying to conceive, are they compatible?

Accepted Answer

If you are a man trying to conceive, it is best to discuss use with a doctor; in some cases finasteride can affect sperm quality. For women the situation is clear: during pregnancy finasteride is contraindicated, because it can interfere with the sexual development of a male fetus. Pregnant women should also not handle broken or crushed tablets.

Question 11

What happens if I stop taking finasteride?

Accepted Answer

Finasteride only works for as long as you use it. After you stop, DHT levels rise again, and over the following months hair loss continues from where it would be without treatment. The gain achieved during treatment is then usually lost. It is best to discuss a planned discontinuation with a doctor.

Question 12

Is finasteride prescription-only?

Accepted Answer

Yes. Both the tablet and the spray are prescription-only in Germany. A doctor prescribes finasteride if they consider treatment to be medically appropriate in the individual case.

Question 13

Does finasteride cause impotence?

Accepted Answer

A minority of men experience sexual side effects, such as reduced libido or erectile problems. In most cases these resolve after stopping the medication; in individual reports they persisted longer. If such symptoms are troubling you, discuss them with a doctor rather than changing your use on your own.

Question 14

Is dutasteride approved for hair loss?

Accepted Answer

No, there is no approved indication for this in Germany. The active ingredient is only approved for benign prostate enlargement; for hair loss doctors use it off-label. The alternative approved for hereditary hair loss in men is finasteride.

Question 15

Is dutasteride stronger than finasteride?

Accepted Answer

For hair loss, dutasteride is not approved in Germany and is only prescribed off-label; the approved option for men is finasteride. At the hormonal level, dutasteride has been shown to lower DHT levels more strongly, because it inhibits both types of 5-alpha-reductase, whereas finasteride mainly inhibits one. Whether this translates into more hair is less clear, and the more extensive long-term data are available for finasteride. The choice is made by the doctor.

Question 16

What side effects can dutasteride have?

Accepted Answer

The profile is similar to that of finasteride: in a minority of men, sexual dysfunction such as reduced libido or erectile problems is possible, and mood changes less often. Because dutasteride acts more broadly on the hormonal system and stays in the body for a very long time, side effects can be more pronounced and last longer. You should have new symptoms checked by a doctor early on.

Question 17

How long does dutasteride stay in the body?

Accepted Answer

A long time. The half-life is several weeks, and the active ingredient is still detectable in the blood months after the last dose. For this reason, men taking dutasteride and for up to six months after the last dose must not donate blood. The long retention time also matters if you are trying to conceive and should be discussed with a doctor beforehand.

Question 18

Is dutasteride an option for women?

Accepted Answer

For women who are pregnant or could become pregnant, dutasteride is contraindicated, because the active ingredient can interfere with the genital development of a male fetus. They should also not handle damaged capsules. Hair loss in women often has different causes and is treated differently; which options may be suitable is determined by the medical health questionnaire on a case-by-case basis.

Question 19

Does dutasteride lower the PSA level?

Accepted Answer

Yes. After a few months, dutasteride lowers the PSA level in the blood by about half. The PSA level is a marker used in prostate cancer screening. If you have such checks, you should tell the treating doctor that you are taking it; for assessment, the measured value is then usually doubled.

Question 20

How long does it take for spironolactone to work?

Accepted Answer

Plan for several months. First visible changes usually appear after three to six months, and the result can often only be reliably assessed after six to twelve months of regular use. Taking stock after a few weeks means judging too early.

Question 21

Can spironolactone and minoxidil be combined?

Accepted Answer

Yes, the two are often combined for hair loss in women, because they act at different points. Spironolactone inhibits the effect of androgens, while minoxidil affects the hair cycle. Whether a combination makes sense in your case is decided by a doctor. Do not combine active ingredients on your own.

Question 22

Spironolactone and wanting to have children, what do I need to be aware of?

Accepted Answer

Spironolactone must not be taken during pregnancy, because it can affect the sexual development of a male fetus. For women who can become pregnant, reliable contraception is important during treatment. If you want to have children, raise this with a doctor before starting.

Question 23

Do I need to have my blood values checked while taking spironolactone?

Accepted Answer

It is possible. Spironolactone can raise the potassium level in the blood. For this reason, a doctor may arrange for blood and kidney values to be checked at the start and over the course of treatment, especially if kidney function is impaired or if you are taking other medicines at the same time. How closely this is monitored depends on your situation.

Question 24

Is spironolactone approved for hair loss?

Accepted Answer

No. In Germany, spironolactone is approved for conditions including high blood pressure, heart failure and fluid retention, but not for hair loss. For hereditary hair loss in women, it is used off-label and is prescription-only.

Question 25

Can men take spironolactone for hair loss?

Accepted Answer

No. Spironolactone is not suitable for men for hair loss, because its antiandrogenic effect can trigger feminizing effects such as breast tenderness. For men, other active ingredients may be an option.
