Hair Loss in Men: What a Barber Recommends After 20 Years [2026]

Every day I sit opposite men whose hair is getting thinner. Some have been coming to me for years, and I see how their hairline changes. Hardly anyone brings it up directly. But sooner or later almost everyone asks the same question: "Ahmed, what else can I do?"

In more than 20 years in the barbershop I have seen a lot of thinning spots and receding hairlines. I am a barber, not a doctor. So this article is not a treatment plan but my honest assessment from practice: what is in your hands, where the limits are, and when you should see a doctor.

Why men lose their hair

Hereditary hair loss (androgenetic alopecia) is the most common form. It affects around half of all men by the age of 50. Hair in certain areas of the head is sensitive to the hormone DHT, a by-product of testosterone. Over the years the hair becomes thinner and shorter. This is not a disease but a predisposition.

There are other causes as well:

• Stress: after a period of heavy strain, hair can fall out more a few months later (telogen effluvium). This usually settles by itself.
• Nutrient deficiency: for example iron or vitamin D. A blood test can check this.
• Illness and medication: for example thyroid problems. That belongs in a doctor's hands.
• Alopecia areata: bald patches without a pattern. Here too: see a dermatologist.

When you should see a doctor

This matters to me, which is why it comes early on. See a dermatologist if:

• the hair loss starts suddenly and heavily,
• bald patches appear without a pattern,
• you also notice tiredness, weight changes or other symptoms,
• you start a new medication and lose more hair afterwards.

With hereditary hair loss: the earlier you get advice, the more options you have. Effective treatments exist, but they belong in a doctor's hands.

What doesn't work, in my experience

I'll say it directly, because in 20 years I have seen too much money sitting in bathroom cabinets:

• Seeing a shampoo as the solution. Whether caffeine or another ingredient: a shampoo is rinsed out after a minute or two. It cares for your hair, but it does not replace a treatment.
• Biotin capsules without a deficiency. Biotin matters for hair, but only if you actually have a deficiency. With a balanced diet that is rare. Have it checked with a blood test before you spend money.
• Waiting and hoping. Most men act too late.

What is in your hands

Care for your scalp

What I always tell my customers: good hair starts with a well-cared-for scalp. If it is irritated, dry or flaky, the hair looks worse too.

• wash with lukewarm rather than hot water,
• shampoo twice and leave it on briefly the second time,
• massage your scalp with your fingertips, not your nails,
• no shower gel on your hair, more on this in Shower gel as shampoo.

Adapt your haircut

This is my field. A good cut makes thinning hair look much fuller: shorter at the sides, some texture on top. Long, heavy hair tends to emphasise thin spots. Talk to your barber about it openly; he can see it anyway.

Take stress seriously

I see it often: under pressure at work, men notice more hair in the sink and then buy even more products. Hair loss caused by stress often only shows two to three months later and usually settles once the strain eases. If your hair suddenly thins evenly across the whole head, think about the last few months first.

My recommendation

If you want my advice: have the cause checked if you are unsure. And take care of the basics you control every day: a well-cared-for scalp, a cut that suits your hair, and a shampoo that cares for scalp and hair instead of drying them out.

I developed our shampoo for exactly this daily care. It is not a treatment for hair loss, and I would never sell it as one. It cares for the scalp and roots with arginine, adds volume with wheat protein and shine with argan oil, so that the hair you have looks stronger and fuller.

For daily care Shampoo with arginine, wheat protein & argan oil

Cares for the scalp and roots, adds volume and shine without silicones. Also without added fragrance for sensitive scalps.
