Hair Loss: Causes & Treatment
Dermatologist-led overview of pattern hair loss, how it is diagnosed and the evidence behind common treatments.
View AAD reference ›Androgenetic alopecia — pattern hair loss — is the most common cause of hair loss in both men and women. It is genetic and DHT-driven, so affected follicles slowly miniaturise over years. It cannot be cured, but it can often be slowed and stabilised when addressed early. Hairsncares helps you check the pattern with an AI hair test and guides you toward dermatologist-reviewed products, a routine and the right medical referral.

Illustrative sample only. AI screening helps guide product choice and does not replace a dermatologist's diagnosis.
The best-evidenced options are topical Minoxidil and, for men, oral Finasteride, used under dermatologist guidance, often alongside supportive shampoos, serums and a healthy scalp. The right combination depends on your sex, pattern, severity and medical history, and treatment is long term because the condition is genetic and progressive. There is no cure, but early treatment can slow loss and support density. These are doctor-guided treatments, so start with an AI hair test and a dermatologist assessment.
Pattern hair loss in men and women is usually progressive but manageable. It needs realistic expectations and doctor-guided treatment planning.
AI Summary
Androgenetic alopecia is one possible hair-loss pattern or trigger. The right next step depends on whether hair is shedding from the root, breaking from the shaft, thinning in a pattern, falling suddenly, persisting for months or appearing in patches.
This page is educational and screening-oriented. It does not diagnose, prescribe or guarantee results. Use the AI Hair Test to organise symptoms, and consult a dermatologist if symptoms are severe, persistent, patchy, painful or progressive.
Best next step: identify the pattern, check likely triggers, review red flags, then choose a routine, product pathway or doctor consultation safely.
Androgenetic alopecia, commonly called pattern hair loss, is the most common cause of hair loss worldwide. It is genetically influenced and driven by the hormone DHT (dihydrotestosterone), to which certain scalp follicles are sensitive. Over repeated hair cycles, these follicles gradually miniaturise — producing finer, shorter, lighter hairs — until visible density drops.
It follows recognisable patterns. In men, it typically starts as a receding hairline and crown thinning and is graded on the Norwood scale. In women, it usually appears as diffuse thinning over the crown with a widening parting and a preserved hairline, graded on the Ludwig scale. Because it is genetic and progressive, it tends to advance slowly without treatment, but it can often be slowed or stabilised when addressed early. It is chronic, so treatment is long term and there is no permanent cure.

| Main driver | Genetics + DHT sensitivity |
| Process | Gradual follicle miniaturisation |
| Men's pattern | Receding hairline + crown (Norwood) |
| Women's pattern | Diffuse crown thinning (Ludwig) |
| Course | Chronic, progressive; slowed by early treatment |

Thinning over the crown / vertex
Widening central parting (women)
Finer, shorter hairs in affected areas
Reduced ponytail thickness (women)
Frontal hairline usually kept (women)

Recognise these signs? Check your pattern and severity with the AI test.
Check My PatternIn people with a genetic predisposition, scalp follicles in certain areas are sensitive to DHT, a potent androgen made from testosterone by the enzyme 5-alpha-reductase. DHT binds to receptors in these follicles and gradually shortens their growth phase. With each hair cycle, the follicle shrinks a little — this is miniaturisation.
As follicles miniaturise, the hairs they produce become finer, shorter and lighter, and some eventually stop producing visible hair. This is why pattern hair loss looks like gradual thinning rather than sudden shedding, and why it follows the same areas (hairline, crown) where follicles are most DHT-sensitive.
Understanding this explains how treatments work: Minoxidil supports the growth phase and follicle activity, while Finasteride (in men) lowers DHT to reduce the driver of miniaturisation. Because the underlying sensitivity is genetic, treatment manages the process rather than removing the cause, which is why it is long term.
Want this explained for your case? A dermatologist can confirm miniaturisation with trichoscopy.
Ask a Hair DoctorPattern hair loss is graded by severity — Norwood for men, Ludwig for women. This simple, educational guide is not a clinical grading; an assessment is more accurate.
Most people get the best results by acting in the earlier stages, when more follicles are still active. Earlier assessment generally means more options.
Wondering which stage you're at? The AI test estimates your Norwood or Ludwig level.
Check My StageThe same DHT-driven process shows up differently, and treatment choices differ — especially around Finasteride.
| Aspect | Men | Women |
|---|---|---|
| Typical pattern | Receding hairline + crown thinning | Diffuse crown thinning, widening parting |
| Hairline | Recedes | Usually preserved |
| Scale | Norwood | Ludwig |
| Often-suited actives | Topical Minoxidil; oral Finasteride (Rx) | Topical Minoxidil for women; treat hormonal cause |
| Finasteride | Considered under doctor care | Not used if pregnant or may conceive |
| Key extra check | Overall Norwood pattern | PCOS / thyroid / iron screening |

Ask a DermatologistAll Ingredients"Androgenetic alopecia is the most common reason people come to see me, and the message I want to leave is realistic and hopeful: we cannot cure it, but we can usually slow it and protect the hair you have, particularly when we start early. In men I assess the Norwood pattern and discuss Minoxidil and Finasteride; in women I look for hormonal contributors and use Minoxidil carefully. These are doctor-guided treatments — never casual purchases — and consistency over months is what makes the difference."

Hair loss treatment should start by identifying the pattern. Pattern thinning, diffuse shedding, patchy loss, sudden shedding and hair breakage need different next steps.
May suggest androgenetic alopecia or DHT-related pattern hair loss. Often gradual and progressive.
Androgenetic Alopecia →May relate to telogen effluvium, deficiency, thyroid, illness, stress, postpartum phase or diffuse pattern loss.
Diffuse Hair Thinning →Often follows a trigger weeks to months earlier, but sudden shedding should not be dismissed if severe or persistent.
Sudden Hair Fall →Persistent shedding needs cause-finding: chronic TE, thyroid, deficiency, medicines, hormones or pattern loss.
Chronic Hair Fall →Patchy loss may be alopecia areata, fungal infection or scarring alopecia and should be dermatologist-led.
Patchy Hair Loss →Breakage is shaft damage, not root shedding. It needs damage repair and styling changes, not root-hair-fall treatment.
Breakage vs Hair Fall →Cause Map
DHT-related follicle miniaturisation causing gradual pattern thinning in men and women.
Read Guide →Diffuse shedding after triggers such as fever, COVID, stress, childbirth, surgery, dieting or deficiency.
Read Guide →Iron, vitamin D, thyroid and nutritional issues can contribute to diffuse shedding and chronic hair fall.
Supplement Safety →Round bald patches need dermatologist diagnosis because causes and treatments differ greatly.
Patchy Hair Loss →Stress, rapid weight loss, illness, smoking and alcohol may contribute, but rarely act alone.
Stress Hair Loss →Breakage from heat, chemicals, friction or styling is different from root hair fall.
Breakage vs Hair Fall →Red Flags
Short-term shedding after a known trigger can be tracked with photos, routine consistency and symptom notes.
Use the AI Hair Test to organise pattern, duration, triggers, scalp symptoms and next-step direction.
Hair fall lasting more than 6 months, worsening crown thinning, a widening parting or unclear shedding needs evaluation.
Patchy loss, scalp pain, pus, crusting, bleeding, scarring-looking skin, sudden severe shedding or child scalp scaling needs prompt medical review.
Progression
Receding hairline, temple recession, crown thinning or a widening parting may appear slowly.
Hair strands become finer over time due to follicle miniaturisation in susceptible areas.
Doctor-guided options may aim to slow progression, support density and protect existing hair.
Progress photos and follow-up help decide whether products, medicines or procedural options are appropriate.
Comparison
| Feature | Pattern Hair Loss | Telogen Effluvium | Hair Breakage |
|---|---|---|---|
| Main sign | Receding hairline, crown thinning, widening parting | Diffuse shedding from all over the scalp | Short broken strands, split ends, roughness |
| Timeline | Gradual and progressive | Often starts after a trigger | Linked to damage, heat, chemicals, friction or styling |
| Root bulb? | May shed miniaturised hairs | Shed hairs often have a root bulb | No root bulb; the shaft snaps |
| Best next step | AI Hair Test + dermatologist review if progressive | Find the trigger + correct the cause | Damage-repair routine + styling changes |
Realistic Expectations
Androgenetic (pattern) hair loss is usually gradual and progressive. Doctor-guided options may aim to slow progression and support density, but no product or routine cures it or guarantees regrowth, and active medicines such as minoxidil or finasteride are doctor-guided and not suitable for everyone.
