Androgenetic alopecia is the most common cause of hair loss in both men and women. Of both genetic and hormonal origin, it leads to a progressive miniaturization of hair follicles, resulting in thinning and then visible thinning of the hair. Contrary to popular belief, it is not a sudden loss but a gradual process that can be slowed down when treated early.
We will explain in detail the mechanisms of androgenetic alopecia, the differences in manifestation in men and women, as well as the medical and surgical treatments currently recognized to slow hair loss and promote hair regrowth.
Let's quickly go into the details. Androgenetic alopecia corresponds to progressive hair loss linked to a genetic sensitivity of the hair follicles to androgens, in particular dihydrotestosterone (DHT). This hormone, derived from testosterone via the enzyme 5-alpha-reductase, causes a progressive reduction in the size of the follicle.
More often referred to as follicular miniaturisation, this phenomenon often results in these symptoms:
According to the medical literature, androgenetic alopecia represents the most common form of hereditary hair loss. It affects around 70-80% of men during their lifetime and up to 40% of women after the menopause.
These data are reported in particular by the clinical reviews available on PubMed and by the MSD Manual, an international reference in dermatology.
It is important to distinguish this pathology from other causes of hair loss, such as alopecia areata (alopecia), which has an autoimmune mechanism.
Although the hormonal mechanism is similar, the clinical expression differs.
Male pattern baldness is generally characterized by:
This progression pattern is classically described by the Norwood-Hamilton scale . For more details, see our dedicated page on the specifics of male pattern baldness .
In women, androgenetic alopecia most often takes the form of:
It can worsen after significant hormonal changes, particularly during menopause. You can find more specific information about female pattern baldness here .
The therapeutic objective is twofold: to slow down progression and to stimulate the regrowth of follicles that are still active. It is essential to understand that no treatment can recreate a totally destroyed follicle.
Topical minoxidil is now one of the reference treatments. It works by prolonging the hair growth phase and increasing local vascularisation. Its efficacy has been documented in numerous clinical studies, including those listed on PubMed.
In men, oral finasteride can be prescribed. It inhibits the enzyme 5-alpha-reductase, thereby reducing the conversion of testosterone to DHT. Meta-analyses published in international dermatological journals show a significant slowdown in progression in a significant proportion of patients.
In women, certain anti-androgen treatments may be considered depending on the hormonal and medical context. For this, make an appointment with our hair expert, Dr. Raphaël Meyer.
The injections of PRP (platelet-rich plasma) are offered as an adjuvant treatment. PRP contains growth factors that may stimulate follicular activity.
Several studies indicate an improvement in hair density in some patients, particularly in the early stages. PRP does not replace basic medical treatment, but can reinforce its effect.
The hair mesotherapy can also be considered as a complementary regenerative treatment. It involves the local injection of vitamins, minerals and low-dose hyaluronic acid to support the follicular environment and optimise the quality of the scalp, particularly in the early stages of alopecia.
Hair transplant is considered when the loss has stabilised and the donor area(s) remain sufficiently dense. It allows "androgen-resistant" follicles to be redistributed to the balding areas.
It does not treat the underlying hormonal cause. This is why a combined approach is often recommended.
Hair regrowth in androgenetic alopecia depends on the stage of development.
When the follicle is still present but miniaturized, appropriate treatment can:
However, when the follicle is irreversibly atrophied, spontaneous regrowth is no longer possible. Hence the importance of early intervention.
It has also been shown that factors such as chronic stress, nutritional deficiencies, or sleep disorders can worsen underlying hair loss. A holistic approach, including lifestyle changes, can optimize outcomes.
For patients wishing to anticipate the progression of their androgenetic alopecia, innovative approaches such as follicular preservation via the HairClone® solution can be considered.
It is not completely reversible. Treatments can slow the progression and improve the density of miniaturized hairs, but they do not recreate a destroyed follicle.
It can begin as early as adolescence. In women, it frequently appears after age 30 or during major hormonal changes (such as menopause). In men, the prevalence increases with age.
Stress does not create a genetic predisposition, but it can accelerate hair loss that is already programmed, notably by shortening the hair growth cycle . See our article on the influence of stress on hair loss for a more detailed answer.
In most cases, yes. Treatments like minoxidil or finasteride require prolonged use to maintain their benefits. Stopping treatment often leads to a recurrence of the process.
"Hello. I'm sharing my story with you with the idea of showing the persistence of the results after two transplants and 4 years since the first one!
My hair loss started gradually about ten years ago. Having a family history on my father's side, I expected it, but that didn't make it any easier. Around the age of 40, the loss of density at the top of my head became difficult to hide. Every morning, combing my hair was a challenge and I dreaded the wind. I tried treatments such as minoxidil foam and dietary supplements for two to three years, with no real results.
Faced with this situation, I began to consider a hair transplant. My online research quickly led me to offers in Turkey, but the mixed testimonials and associated risks prompted me to turn to closer facilities. An initial consultation at a clinic in Geneva was disappointing: unreassuring premises, a fake doctor, an aggressive sales pitch... This experience prompted me to dig deeper, until I discovered Dr Meyer's clinic. The contrast was immediately striking: a professional welcome, impeccable premises, clear and honest information. During the interview, Dr Meyer assessed my situation, confirmed that there were no contraindications, and presented me with a detailed proposal. There was no pressure, just an honest discussion about the possibilities, the limits and the steps involved. Reassured, I decided to go for it.
First surgery - October 2021
On the first day, I was looked after from 7am until around 7pm. As I'm fairly sensitive to medical procedures, I had a fairly noticeable dip towards the end. The team was very attentive and Dr Meyer, concerned for my well-being, contacted my wife to come and collect me. The next day, after a fairly quiet night's sleep all the same, the second day went better, not having to experience these symptoms again.
After the operation, I followed the post-operative instructions: Gentle washing, sleeping precautions, local care... I was just a little apprehensive about scraping off all the scabs at the risk of damaging the grafts, but I was able to exchange views with the clinic, which guided me step by step, and I had a check-up consultation a week later. The first few months showed gradual progress. The grafts took well, and regrowth took place within the timeframe announced. Follow-up consultations took place at 3, 6 and then 12 months.
Second operation - October 2022
A year later, after our last follow-up interview for the 1st procedure, I therefore opted for a new graft, to reinforce the density in the same area. The operation was shorter and lighter than the previous one, involving fewer grafts. What's more, I knew the protocol, which meant I was much more relaxed.
The post-operative period was simpler too. I didn't need any special assistance. I only rested for two or three days, as opposed to a week the first time. Once again, I followed the recommended precautions: wearing a bandana for about ten days, local care, strict hygiene.
Long-term results and feedback
Four years after the first transplant, the result is more than satisfactory. My hair has regained its natural density. The volume is there and the implantation is harmonious. The people around me have welcomed the change: my family knew about it, and my close colleagues have reacted positively, often surprised, but in a benevolent way.
Since the operation, I have continued with the treatment prescribed by Dr Meyer: minoxidil and finasteride, with no side effects to date. The follow-up has been rigorous and caring. I can only recommend the Clinique de la Croix d'Or to anyone considering a transplant. It's a process that may seem "secondary" to some, but for me it has been a real turning point.
If you have any questions, please don't hesitate."
