Androgenetic alopecia is one of the most common causes of gradual thinning and loss of density. Its real catch is that it begins quietly: a person may go years without seeing much hair on the brush, and so does not take it seriously. Meanwhile the changes are underway.
Early signs worth noticing
- The parting has become noticeably wider, especially under direct light.
- The frontal hairline has changed.
- Hair has become finer at the front or the crown.
- Overall volume has dropped and the ponytail feels thinner.
- Neighbouring hairs clearly differ from one another in thickness.
That last sign - hairs of differing thickness side by side - is especially telling. On trichoscopy the doctor sees it as anisotrichosis: thick, normal and very fine (vellus) hairs growing together. It is one of the early objective signs of miniaturisation, invisible to the naked eye.
What happens to the hair
The core mechanism is a genetically determined sensitivity of the follicles to dihydrotestosterone (DHT) - the active form of the male hormone, which women have too. Under its influence the follicle gradually miniaturises: each new hair grows finer, shorter and weaker than the last. The hair does not so much “fall out” as “shrink.”
That is why androgenetic alopecia is easy to underestimate at the start: the brush looks unchanged, while the overall volume quietly diminishes.
How it is confirmed
Self-diagnosis is unreliable here: a wider parting can also be temporary telogen shedding rather than androgenetic alopecia, and the treatment differs. The diagnosis rests on the whole picture: the pattern of thinning, trichoscopy, history (including family history) and, where needed, blood work to rule out contributing causes such as deficiencies or hormonal issues.
What to expect from treatment
Androgenetic alopecia is a chronic condition, and the goal of treatment is usually not to “bring back everything you had at 18” but to halt progression and support the hair you have. The approach is individual and long-term. Realistic expectations matter: stabilisation and gradual improvement are a success - and an achievable one, if you start in time.

Frequently asked questions
- At what age does androgenetic alopecia start?
- It varies. It can begin as early as 18-20, or show up considerably later. The age of onset and the speed are largely determined by genetics, so there is no single “timeline” that fits everyone.
- Do women get androgenetic alopecia?
- Yes. In women it more often appears as diffuse thinning along the parting and at the crown, without the obvious receding of men. The frontal hairline is usually preserved. Because the picture is less clear-cut, women often seek help later than they should.
- How do I tell androgenetic alopecia from ordinary shedding?
- Ordinary (telogen) shedding is mostly about the amount of hair on the brush; it is often acute and linked to a trigger. Androgenetic alopecia is about gradual thinning and uneven hair thickness; it is chronic and quiet. Trichoscopy is what reliably tells them apart.
- Can androgenetic alopecia be fully cured?
- It is a chronic condition, so it is more accurate to talk about control than a full cure: halting progression and supporting the hair. With an early start and a consistent approach the condition can be stabilised for the long term - which is why the key is not to put off diagnosis.
- Is androgenetic alopecia hereditary?
- Yes - the predisposition is largely genetic and can come from either parent. But an inherited tendency is not a fixed fate: the age of onset, the speed and how noticeable it becomes vary even within one family, and starting treatment early makes a real difference to the outcome.
