Hirsutism is a topic that often stirs up a lot of emotion — because it is not just about the skin, but also about comfort, self-confidence and everyday life. It is worth understanding properly, because not every visible body hair means hirsutism, but equally not every problem can be dismissed as "just the way you are."
Hirsutism is the presence of male-pattern hair growth in women, meaning hair in areas typically associated with androgen activity — the chin, upper lip, chest around the nipples and sternum, abdomen and back. The hair is usually darker, coarser and more noticeable than a person's typical body hair. The key point is that it is not about isolated hairs, but about a pronounced, widespread pattern of increased hair growth in these areas.
This is a very important distinction, because not every hair on the chin, around the nipples or on the abdomen indicates hirsutism. Many women develop isolated hairs in these areas, and this is related to genetic predisposition or the natural sensitivity of hair follicles to androgens. Hirsutism is a situation where the hair growth is pronounced, diffuse and intensified — not the occasional stray hair appearing from time to time.
The most common cause of hirsutism is hormonal imbalance, including polycystic ovary syndrome, elevated androgen levels, increased sensitivity of hair follicles to hormones, and less frequently other endocrine conditions. Sometimes, however, the problem persists despite normal test results — in which case we are dealing with a genetic predisposition.
To understand why hirsutism so noticeably changes the character of body hair, it helps to know what happens at the level of the hair follicle itself. Every hair goes through a cycle made up of three phases — anagen, or active growth, catagen, a transitional phase, and telogen, a period of rest and shedding. How long the anagen phase lasts determines how long, thick and visible the hair will be. Androgens extend the anagen phase in body hair — the hair grows for longer, becomes thicker and darker. At the same time, they promote the conversion of vellus hair, which is fine and light, into terminal hair — coarse, dark and clearly visible. It is precisely this mechanism that causes hair changes in hirsutism not only in typically androgen-dependent areas, but also leads many women to notice generally stronger and darker hair growth across the entire body.
This mechanism is directly relevant to laser hair removal. The laser targets hair in the anagen phase, and the extension of this phase by androgens alters the dynamics of the growth cycle. In practice, this means the treatment protocol must be tailored individually — both in terms of intervals between sessions and the number of treatments. I have written in detail about what laser hair removal looks like in hormonal areas — from qualification to maintenance sessions — in a separate article on the blog.
It is worth paying particular attention when hair growth has appeared suddenly or is rapidly intensifying, is very dense, is accompanied by other symptoms such as acne or irregular cycles, or when the problem is markedly different from what was there before. In such situations, a consultation with an endocrinologist can rule out or confirm a hormonal cause.
In the majority of cases, hirsutism is not a condition that can be cured once and for all. The underlying cause can be treated effectively — for example, by stabilizing hormone levels in PCOS — but the predisposition itself, the sensitivity of hair follicles to androgens, remains. This is why with hirsutism we speak of management and improved comfort, rather than a permanent cure. Laser hair removal is one of the most effective tools in this context — it significantly reduces hair growth, improves comfort and eliminates associated problems such as ingrown hairs and inflammation. Any new hairs appearing over time are not a relapse, but the result of ongoing androgen activity on further follicles — and they can be managed with maintenance sessions.
The phrase "it's just the way you are," often heard in doctors' offices, can be difficult to accept — especially when the problem genuinely affects daily life. In reality, it most often simply means that the cause is genetic, hormonal results are normal and there is no indication for pharmacological treatment. It does not mean nothing can be done. It does mean, however, that it is worth approaching the problem with awareness — understanding its mechanism, accepting what lies beyond our control, and making use of the tools that genuinely improve the situation.
Frequently asked questions
Is hirsutism a disease?
Hirsutism in itself is not a disease, but it can be a symptom of hormonal disorders such as polycystic ovary syndrome. This is why it is worth consulting an endocrinologist when hair growth is pronounced, in order to rule out or confirm a hormonal cause.
Can hirsutism be cured?
In most cases, no — hirsutism is a condition one lives with. The hormonal cause can be treated and hair growth effectively managed, but the genetic predisposition, the sensitivity of follicles to androgens, remains. This is why we speak of management and improved comfort rather than a permanent cure.
Do a few hairs on the chin already mean hirsutism?
No. Isolated hairs on the chin, around the nipples or on the abdomen are in many women simply a matter of genetics and the natural sensitivity of follicles to androgens. Hirsutism is a situation where hair growth is pronounced, diffuse and intensified in areas typical of androgen activity.
Why is hair thicker and darker in hirsutism?
Androgens extend the anagen phase, the period of active hair growth, and promote the conversion of vellus hair into terminal hair — coarse, dark and visible. This is why hirsutism changes not only the quantity, but also the quality and character of body hair, often across the entire body.
Does laser hair removal help with hirsutism?
Yes — laser hair removal is one of the most effective tools for managing hair growth in hirsutism. It significantly reduces the amount and thickness of hair and eliminates ingrown hairs and inflammation. If the hormonal cause is not stabilized, isolated new hairs may appear over time, but the situation can be managed with maintenance sessions.
