Minoxidil: understanding its effects, side effects, and expectations

Many people consider Minoxidil a logical first step for thinning hair. The product has been well-researched and can be effective, but its efficacy varies depending on the situation and it can sometimes be associated with side effects. In this blog, you'll learn how Minoxidil works, what happens during the shedding phase, what clinical results are known, and which factors determine if it might be useful for you. This neutral explanation will help you make an informed decision.

What Minoxidil does: a simple explanation

How Minoxidil works in the hair follicle

Minoxidil stimulates blood flow around the hair root and helps hairs transition faster from the resting phase (telogen) to the growth phase (anagen). This can make hairs thicker, stronger, and more active. This effect is particularly useful for early-stage hereditary hair loss, when hairs are still present but slowly weakening.

The shedding phase explained

A well-known aspect of Minoxidil is the temporary shedding phase. As the growth cycle is reactivated, older hairs fall out more quickly. This can last for several weeks and is considered by researchers to be a normal part of the transition to a new growth period. Therefore, shedding does not mean that Minoxidil is not working; rather, it indicates that the cycle is shifting.

Potential side effects

While Minoxidil is generally considered safe, the following reactions can occur:

  • mild to moderate irritation or itching

  • redness or flaking

  • temporary increase in hair loss (shedding)

  • unwanted hair growth in areas where the product touches the skin

  • rare: palpitations or low blood pressure with improper use

The extent to which someone experiences these varies greatly.

What clinical studies show

Key findings from literature:

  • 5% Minoxidil generally performs better than 2%, for both men and women.

  • Results often become visible after 8–12 weeks, with clearer improvements around 4–6 months.

  • The effect is not permanent; when you stop using it, the previous pattern of hair loss returns.

  • The product works particularly well on hair that is still present but thinning; completely vanished follicles usually do not respond.

Why this is relevant for people with hair loss

The importance of timing and consistency

Minoxidil works best for early or nascent hair loss. It also requires daily and long-term use. Many people stop too early due to the shedding phase or skin reactions, which prevents the full effect from becoming visible.

What you can realistically expect

The results of Minoxidil vary. Some people see a clear increase in density or fuller hair, while others mainly experience stabilization. Since it does not address an underlying cause but supports the growth cycle, consistency remains key.

In short

  • Minoxidil can be effective, especially in the early stages.

  • Shedding is part of the process and is temporary.

  • Side effects occur but are usually mild.

  • Long-term use is necessary to maintain results.

Hairborn® perspective

At Hairborn®, we believe it's important for people to have a clear, neutral, and realistic understanding of all available options. Minoxidil is valuable for many users, but it's not suitable for everyone — for example, due to scalp sensitivity, typical hair texture, or the obligation of daily use.

Our Hairborn® Growth Serum uses a combination of Hairborn Complex™, Baicapil™, Procapil™ and 7 other active ingredients. These ingredients have been extensively studied in independent clinical and ex vivo research. Some results from technical dossiers:

  • Hairborn Complex™ showed a +214% increase in hair growth in ex vivo research after 10 days, compared to +118% for Minoxidil 1%.

  • In a clinical study, users reported an average of +10,200 new hairs after 3 months, with 85% seeing improvement.

  • Baicapil™ shows up to −60% less hair loss in clinical measurements after 3 months.

  • Procapil™ significantly improves the anagen/telogen ratio and supports follicle strength.

These complexes target multiple growth pathways in the follicle and are generally well-tolerated without the typical Minoxidil shedding.

We remain transparent: no single ingredient works for everyone, results vary per person, and consistent use remains essential. Our formula is developed in the Netherlands, produced in the EU, and based on scientifically proven active ingredients.
