Question 1

How quickly will I see results?

Accepted Answer

Hair grows slowly, so a therapy takes patience. The first visible changes usually appear after three to six months, and the fuller result often only after about twelve months. How pronounced the change is varies from person to person and also depends on the starting point. A little patience is important, because a reliable picture only emerges over this period.

Question 2

Which active ingredients does Justhair use?

Accepted Answer

For hereditary hair loss (androgenetic alopecia), finasteride and minoxidil are the main options, the two well-studied active ingredients. They can be used individually or in combination: Finasteride targets the main hormonal cause of hereditary hair loss. Minoxidil supports hair growth at the hair root. Whether and in which form an active ingredient is an option for you, topically as a spray or orally, is decided by the doctor after the health questionnaire. For minoxidil, oral use is not approved for this purpose in Germany and is off-label, that is, based on a doctor's benefit-risk assessment in the individual case. A prescription is only issued if a therapy is medically suitable.

Question 3

How does finasteride work?

Accepted Answer

In hereditary hair loss, the hair roots are sensitive to the hormone DHT (dihydrotestosterone). It causes the follicles to gradually shrink, the hair becomes thinner and falls out earlier. Finasteride inhibits the enzyme 5-alpha-reductase, which converts testosterone into DHT, and thereby lowers the DHT level. This can slow down or stop hereditary hair loss, and in some men the hair becomes denser again. The effect sets in slowly and only lasts with continued use. Finasteride is prescription-only and intended for men. Whether it is suitable for you is clarified by the doctor based on your answers from the health questionnaire.

Question 4

How does minoxidil work?

Accepted Answer

Minoxidil acts directly at the hair root and extends the growth phase of the hair, so that resting follicles can move back into the active phase. The exact mechanism of action has not been fully clarified; improved blood flow to the scalp is also discussed as a contributing factor. Minoxidil can be applied topically as a spray on the scalp or taken orally. The oral form is not approved for this purpose in Germany and is off-label, based on a doctor's assessment in the individual case. Minoxidil is often combined with finasteride because the two active ingredients work at different points. Here too, the effect only becomes apparent after months and only as long as use is continued. Which form makes sense for you is decided by the doctor.

Question 5

What side effects are possible?

Accepted Answer

Side effects are possible and depend on the active ingredient and the dosage form. A brief overview: Topically applied minoxidil can irritate the scalp, for example with itching, redness or dryness. Orally taken active ingredients act throughout the body and can have systemic side effects, for example sexual dysfunction with finasteride. Which side effects are relevant to your therapy is listed in the package leaflet of the respective medicine. Before a prescription is issued, the doctor checks your information for contraindications. If symptoms occur, discuss them early with your doctor so that the therapy can be adjusted.

Question 6

What happens if I stop the therapy?

Accepted Answer

The effect lasts only as long as you continue the therapy. If you stop it, hereditary hair loss usually returns within a few months. The hair that grew back in the meantime can then fall out again as well. This is due to the cause itself: the hair loss is hereditary and cannot be cured, only held back for as long as the active ingredients are working. If you want to pause or stop, discuss it with your doctor. That way you can understand what it means for how things develop for you.

Question 7

How long does it take until results become visible?

Accepted Answer

A treatment can only be reliably assessed after several months. A rough guide: After three to six months, first changes usually appear, such as reduced hair loss. After about twelve months of regular use, the lasting result is usually visible. At the beginning, hair loss can briefly increase. This shedding is a normal sign that the hair growth cycle is restarting, and not a sign that the treatment isn't working. The timing and extent differ depending on your starting point. What matters is using the treatment consistently.

Question 8

Which types of hair loss are treated?

Accepted Answer

We treat hereditary hair loss (androgenetic alopecia), the most common type of hair loss in men and women. This includes a receding hairline at the temples, thinning at the crown, and diffuse thinning across the scalp. The active ingredients finasteride and minoxidil may be considered for this, either topically as a spray or orally, depending on the doctor's assessment. Both are well studied for hereditary hair loss. Hair loss can also have other causes, such as nutrient deficiencies, thyroid problems, or stress (telogen effluvium). Whether your type is hereditary and can be treated is something a doctor determines based on your health questionnaire. For other causes, a different assessment may be advisable.

Question 9

Are there side effects?

Accepted Answer

Yes. As with any medication, side effects can occur; they vary depending on the active ingredient and the form of administration. Here are the most important ones in detail. With topically applied minoxidil, scalp irritation is the most common, such as itching, redness, or dry skin. Less commonly, unwanted hair growth on other parts of the body, headaches, dizziness, or a racing heartbeat can occur. Taking it orally can have a stronger effect on the whole body, for example on blood pressure and circulation. With finasteride, sexual dysfunction is possible, such as reduced libido or problems with erection and ejaculation. Some users report mood swings or depressive moods. Very rarely, allergic reactions or fluid retention can occur. Before every prescription, a doctor checks your information for contraindications, and the treatment is medically supervised. If you experience any symptoms, report them early so the treatment can be adjusted.
