There are few subjects about which as many half-truths circulate as hair loss. Every year, new shampoos, supplements, and treatments appear that promise what they rarely deliver. If you have ended up here, you probably just want to know what actually works and what you can safely skip. We try to answer that as honestly as possible here.
Understand first, then tackle
Most men with hereditary hair loss (androgenetic alopecia) are not dealing with one problem, but three at the same time:
- DHT — a hormone that is created from testosterone and gradually shrinks sensitive hair follicles. The hairs that grow back become thinner and shorter, until they are barely visible anymore.
- Blood flow — when blood supply to the scalp decreases, hair follicles receive less oxygen and nutrients.
- Dormant hair follicles — follicles that are not actively dead, but are inactive. With the right stimulus, they can sometimes still be reactivated.
Why is that relevant? Because most treatments only work on one of these three factors. And that largely determines how well they work.
What science says about the best-known options
Finasteride is a prescription DHT blocker. It inhibits the enzyme that converts testosterone into DHT and has been well-studied clinically: in most users, it demonstrably slows hair loss, and for some, hair grows back. It works, but it is also a medication with side effects in a small percentage of users, including libido problems. Moreover, you need a prescription, and the effect stops as soon as you stop taking it.
Minoxidil has been available for decades as a lotion or foam and improves blood flow to the scalp. It works for most men to slow down hair loss. Some see new hair growth. But here, too, the rule applies: if you stop, the hair loss starts again. Some men experience a temporary shedding effect in the first few weeks where they seem to lose more hair. That is annoying, but normal.
Supplements such as biotin, zinc, or vitamin D are often recommended, but the honest conclusion is that supplementation only makes sense if you actually have a deficiency. Without a deficiency, you won't get much out of them, no matter how convincing the packaging looks.
Dermarolling is an approach that is increasingly being studied. A dermaroller with tiny needles rolls over the scalp and creates microscopic wounds. This activates the body's repair response, improves blood flow, and can stimulate dormant hair follicles. Research published in the International Journal of Trichology showed that microneedling combined with an active serum worked significantly better than the serum alone.
Hair growth serums combine multiple active ingredients in one product. The most effective formulas contain substances that inhibit DHT, improve blood flow, and directly stimulate hair follicles. Compared to minoxidil, the advantage is that you don't need a prescription, the chance of irritation is smaller, and a good formula addresses multiple causes at once.
Why the combination works
The common thread in all research is quite clear: those who address only one of the three causes get fewer results than those who address all of them. Inhibiting DHT without improving blood flow works, but to a limited extent. Improving blood flow without addressing DHT does too.
A good serum combined with regular dermarolling is the most accessible way for most men to address all three factors. The serum provides the active ingredients, the dermaroller ensures better absorption and stimulates the scalp via microneedling. For those who want more, it can be supplemented with finasteride via a doctor.
One thing is certain: results do not come quickly. The hair growth cycle lasts for months. If you don't see anything after three weeks, you shouldn't stop. It is realistic to notice the first changes after 90 days, and only have a full picture after six months.
Hairborn® perspective
Tackling hair loss starts with understanding what is going on and then acting consistently. Hairborn® works with clinically researched ingredients that address the three core factors: DHT, blood flow, and hair follicle stimulation. No spectacular promises, but an approach that is scientifically substantiated and aimed at long-term results.

Frequently asked questions
Do you have to talk to a doctor before starting treatment?
It is not mandatory, since products like minoxidil and cosmetic serums are available without a prescription, but it is wise, especially if you are unsure about the cause of your hair loss or if you are considering using finasteride. A doctor can rule out other underlying causes, such as a thyroid problem or a deficiency.
How much does an approach with minoxidil, finasteride, or a serum cost per month?
Costs vary widely. Minoxidil usually costs between 15 and 30 euros per month, finasteride via prescription is comparable or slightly higher, and a well-formulated serum is generally in the same price range. A dermaroller is a one-time purchase that lasts for months. The total costs therefore mainly depend on which combination you choose, not on a single product.
Can you use minoxidil, finasteride, and a serum at the same time?
Yes, you can, because all three work through different mechanisms: finasteride via hormone regulation, minoxidil via vasodilation, and a serum often via direct stimulation of the hair follicle. If in doubt, consult a doctor, especially if you are adding finasteride, to make sure the combination is useful for your situation.
Which treatment provides the fastest result?
No treatment provides spectacular results in the short term, because the hair growth cycle simply takes months. In clinical studies, minoxidil and finasteride often show the first measurable changes around three months, but that varies greatly per person and is no guarantee of a faster feeling of results.
Is it smart to start with the strongest option immediately for advanced hair loss?
Not necessarily. Even with advanced hair loss, it is common to start with the least intrusive options and build up from there, unless a doctor advises otherwise. Grabbing the strongest medication immediately primarily increases the risk of side effects without it being proven to work faster than a gradual approach.
Can you switch from one treatment to another without problems?
Yes, you can, but build up the new treatment gradually instead of switching completely in one go. When stopping one treatment, there may be a temporary period where the hair growth cycle has to adjust, so give it some time before passing judgment on the new approach.
Can a combination of treatments also have the opposite effect?
In rare cases, a combination of multiple active products can overload the scalp, resulting in irritation or increased sensitivity. That is not a reason to avoid combinations, but it is a reason to introduce new products one by one so you know what is causing any reaction.
Is it necessary to have blood values tested before starting?
That is not standard for cosmetic options such as a serum or dermaroller, but it can be useful if you are in doubt whether an underlying hormonal or nutritional cause plays a role. Based on blood values, a doctor can better estimate whether a supplement will actually make sense for you.
What is the difference between stopping because something doesn't work and stopping because you are done?
Stopping because something doesn't work means that you have not seen any difference after an honest trial period of at least three to six months. Stopping because you are done can also mean that you are satisfied with the achieved result and are considering continuing at a maintenance level, for example with less frequent use.
How do you know which of the three causes plays the biggest role for you?
In practice, it is difficult to determine this exactly without medical examination, but the pattern of your hair loss does provide clues. A clearly receding hairline is more often indicative of DHT sensitivity, while a generally thinning scalp without a clear pattern is more often related to blood flow or other factors. If in doubt, a doctor or dermatologist can provide a better-substantiated answer.
