Hair loss in men — receding hairline and crown thinning without panic

What is actually happening — the mechanism without unnecessary jargon

Hair does not ‘fall out’ overnight. The hair growth cycle lasts several years. Each follicle goes through growth, transition and resting phases before the cycle begins again. In male pattern baldness, the cycle gradually shortens. The follicle miniaturises and the hair becomes progressively thinner and shorter, until it stops growing back. The cause is DHT — dihydrotestosterone, a derivative of testosterone. The more sensitive your follicles are to DHT, the faster they miniaturise.

This explains two things: why hair loss is genetic (follicle sensitivity is inherited, not testosterone levels — the myth of ‘bald fathers’ does not apply here) and why it starts in specific areas. The hairline and crown are naturally more susceptible to DHT than the sides and back of the head. This creates the characteristic pattern — hair remains at the back, while the centre and front recede.

Alongside male pattern baldness, there are other causes of hair loss worth ruling out: iron, zinc, biotin and vitamin D deficiencies, thyroid disorders, severe stress (telogen effluvium — hair falls out in waves 3–4 months after a stressful event) and protein deficiencies. These causes are reversible. This is why diagnosis is more important than quickly starting supplements without proper guidance.

The pattern you see in the mirror — what the Norwood scale tells you

Doctors and trichologists use the Norwood scale to describe the stage of male pattern baldness in men. It is a simple tool that helps determine where you are and what you can realistically achieve.

1. 01

   Norwood I–II — early receding hairline

   The hairline recedes slightly at the temples. This is the best time to act — the follicles are still active, and the response to treatment is often good.

2. 02

   Norwood III — noticeable receding hairline and/or thinning crown

   The receding hairline is already noticeable, and the crown may be thinner. It is still a good time for intervention — there is still a substantial reserve of active follicles.

3. 03

   Norwood IV–V — baldness at the crown

   The receding hairline and crown meet or are close to meeting. Conservative options may slow progression. For some men at this stage, a hair transplant is a realistic option.

4. 04

   Norwood VI–VII — advanced baldness

   A strip of hair remains at the sides and back. A transplant is possible, but requires a suitable donor area. Conservative methods mainly work preventively on the remaining hair.

What works and what does not — practically

The market is flooded with ‘anti-hair loss’ shampoos, biotin supplements marketed as breakthroughs and miracle topical products. Before spending time and money, it is worth knowing what has real evidence behind it and what is mainly good marketing.

PRP and scalp mesotherapy — what they are and who they may help

Two salon methods that have gained popularity in recent years for hair loss in men are platelet-rich plasma (PRP) and scalp mesotherapy. It is worth understanding the difference.

• PRP — platelet-rich plasma: your own blood is drawn, and a laboratory centrifuge separates a platelet concentrate rich in growth factors. It is then injected into the scalp. Platelets release repair signals — this may stimulate follicle activity and improve their nourishment. Many men see reduced hair loss and improved hair density after a series of treatments.
• Scalp mesotherapy: intradermal micro-injections of cocktails containing amino acids, vitamins, peptides and other active ingredients. It strengthens the follicle environment and may improve their nourishment and hair condition.
• Combining both: trichologists often combine these methods with daily care (minoxidil) for comprehensive action at different levels.

Both methods work best in early and intermediate stages of hair loss, when there are still active follicles in the scalp to stimulate. The earlier you start, the more there is to preserve — and the better your response to treatment may be.

When to act — there is no perfect moment, but there can be too late

The most common mistake is postponing the decision. ‘I will wait another year’ — and a year later, follicles that could have responded to treatment are no longer active. Hair is not like a nail. Miniaturisation leads to follicle loss, and no conservative treatment can restore a lost follicle.

A trichology Consultation does not commit you to treatment. It is a condition assessment — trichoscopy, scalp assessment and medical history. Afterwards, you know how many active follicles remain, what a realistic goal is and what makes sense in your case. You may decide to do nothing — but at least you will know what you are losing and at what pace.

For many men, the biggest surprise is that the best response to treatment comes when the problem is still ‘small’. It is a paradox: when a receding hairline is barely visible and you think, ‘there is nothing to worry about’, that is the best time to act. When baldness is already noticeable and you ‘really need to do something’ — some options have already passed.

Everyday care — what you can do yourself and what requires a salon visit

Not everything has to start at a salon. Here are a few evidence-based steps you can take yourself:

• Minoxidil — available over the counter at pharmacies as a solution or foam; regular use is essential, and breaks in application reverse the effect
• Full blood count and biochemical panel — before starting supplements, check your ferritin, zinc, vitamin D and thyroid levels; correct deficiencies purposefully, not blindly
• A diet rich in protein and zinc — hair follicles are protein structures; a calorie or protein deficiency can increase shedding
• Reducing strong detergents in shampoos — sodium lauryl sulphate (SLS) dries the scalp and may worsen irritation; it will not stop androgenetic alopecia, but reducing it will not do any harm
• Regular progress checks — take a photo of your temples and crown in the same lighting each month. This is the only reliable way to assess whether things are moving in the right direction.

Visit a trichology salon for trichoscopy, PRP, scalp mesotherapy and a prescription for medication, if the doctor considers it indicated. These are not treatments you can perform at home yourself — and you should not try.
