Fizzy hair in men: what causes it and what can you do about it?

Short answer: Frizzy hair occurs when the hair cuticles are open, causing moisture to evaporate and the hair to lose its smooth texture. With the right care, a mild shampoo and hydration, frizzy hair can be effectively improved in most men.

Frizzy hair is a daily nuisance for many men. It looks unruly, feels dry and refuses to stay in place, no matter how you style it. Many men think it’s simply their hair type, but frizzy hair is often a sign that your hair is damaged, lacks moisture or isn’t being cared for properly. In this article, you’ll find out what causes frizzy hair, how to recognise damage and what actually helps.

What exactly is frizzy hair?

Frizzy hair occurs when the outermost layer of the hair shaft – the cuticle – becomes damaged or lifts. The cuticle consists of small overlapping scales which, when healthy, lie flat against the hair shaft. When these scales lift, the hair loses its smooth surface and moisture can escape. The result: hair that looks dry, dull and unruly.

A systematic review shows that the lipid layer on the hair scales, known as 18-MEA, determines how hydrophobic and smooth the hair is. As soon as this lipid layer becomes damaged or is missing, the hair’s susceptibility to frizz increases significantly. The hair then absorbs moisture from the air more easily, which exacerbates the unruly texture.

What are the main causes of frizzy hair in men?

The most common cause is simply dryness. Prolonged exposure to the sun, dry air, sea water or a high-temperature hairdryer strips the hair of moisture and damages the cuticle scales. However, daily habits also play a major role.

Research shows that both chemical and physical treatments damage the cuticle structure, leading to increased porosity and frizz. This applies to the use of heat styling, but also to harsh sulphate-based shampoos that strip away the hair’s natural protective oil film. Washing too frequently exacerbates this effect: washing daily with a harsh cleanser also removes the protective layers that keep the hair supple. Insufficient hydration, an inadequate repair routine and the use of alcohol-based styling products complete the picture.

How can you tell if your hair is damaged?

Damaged hair has a number of recognisable characteristics. It looks dull rather than shiny, breaks more easily when combed or styled, and is difficult to smooth out. The most obvious sign is a straw-like texture: if your hair feels like straw or hay, it is almost certainly suffering from dehydration or structural damage.

Research into heat damage shows that repeatedly subjecting hair to heat causes measurable structural damage to both the cuticle and the cortex, the inner core of the hair. This damage is cumulative: every time you blow-dry your hair or use a straightener without protection, you accumulate a little more damage. Once hair is structurally damaged, it does not fully repair itself, but you can limit further damage and visibly improve its condition.

What really helps with frizzy hair?

The basis of any approach is a mild, sulphate-free shampoo. Sulphates are too harsh for most hair types: they remove not only dirt but also the protective layer of oil that keeps the cuticle sealed. If you switch to a mild shampoo, you’ll notice a difference after just a few weeks.

Research shows that treatments containing proteins and polysaccharides can prevent cuticle damage and strengthen the hair. A moisturising conditioner or hair mask, used weekly, helps to seal the cuticle and lock in moisture. Applying argan or jojoba oil to damp hair visibly reduces frizz. If you use a hairdryer, set it to a low heat setting and use a wide-toothed comb instead of a brush.

Consistency is crucial here. According to Thuisarts.nl, dryness and irritation of the scalp are factors that contribute to changes in hair quality; a healthy scalp is the foundation for healthy hair.

Can diet or lifestyle affect frizzy hair?

Yes, and this influence is often underestimated. Hair consists largely of keratin, a protein. An insufficient protein intake means there is less building material for healthy hair. Omega-3 fatty acids support the distribution of lipids in the hair shaft, and a zinc deficiency disrupts cell renewal in the hair follicles.

Stress, lack of sleep and smoking affect blood flow to the scalp, meaning hair follicles receive fewer nutrients. Small lifestyle changes can therefore make a noticeable difference to the condition of your hair.

When should you consult a doctor?

If frizzy hair is accompanied by hair loss or a receding hairline, there may be an underlying issue. Thinning hair can be an early sign of androgenetic alopecia, in which DHT causes the hair follicles to miniaturise. Thinner hair is structurally more fragile and therefore more prone to frizz.

Other causes that can affect hair condition include thyroid problems or iron deficiency. If you’re unsure, a medical assessment is advisable. You can read more background information in our article on causes and prevention of hair loss.

How does Fellos help with hair problems such as frizzy or thinning hair?

Fellos offers online medical guidance for men with hair problems. Through a three-minute online assessment, a Dutch doctor will evaluate your situation: is it simply hair damage, or is androgenetic hair loss a factor? Based on this, a personalised treatment plan is drawn up. If medication such as finasteride and minoxidil for hair loss is appropriate, it will be prescribed and discreetly delivered to your home. A hair loss treatment with Fellos is therefore accessible and quick.

Microscopic examination shows that chemical styling products damage the cuticle layers of the hair shaft. If you regularly use styling chemicals and notice that your hair is becoming increasingly dry and frizzy, a consultation with a doctor is a logical next step to rule out any underlying causes.

Restore your hair’s condition with Fellos’ help

In most cases, frizzy hair is a sign that your hair needs extra care, not an unsolvable problem. With the right shampoo, hydration and a few adjustments to your routine, you’ll see results. But if your hair is also thinning, falling out or remains chronically dry, it’s wise to have this assessed. At Fellos, you can start an online consultation and receive a personalised assessment from a Dutch doctor. This way, you’ll know exactly what your hair needs and which approach suits you best.

Frequently Asked Questions

Why does my hair go frizzy after a shower?

After a shower, the hair cuticles are open due to the heat and moisture. If you then rub your hair dry with a rough towel or blow-dry it straight away on a high heat setting, the cuticles won’t close properly. Use a microfibre towel, pat gently and blow-dry on a low heat setting to reduce frizz.

Can I prevent frizzy hair without expensive products?

Yes. The biggest difference comes from small habits: wash less often, use cold water for the final rinse, avoid high blow-dry temperatures and use a conditioner after every wash. Inexpensive sulphate-free shampoos work just as well as expensive ones, as long as they’re mild.

Is frizzy hair a sign of hair loss?

Not always. Frizzy hair is usually caused by dryness or damage. However, if your hair is also becoming thinner, falling out or you’re noticing a receding hairline, there may be an underlying cause such as hereditary hair loss. In that case, it’s wise to consult a doctor.

Does hair care oil really help with frizzy hair?

Yes. Light oils such as argan or jojoba oil form a protective layer around the hair shaft and help keep the cuticle sealed. Apply a small amount to damp hair, not to the scalp itself. Don’t use too much: a few drops are enough for most hair lengths.

How long will it take before I see results from an improved hair care routine?

For most men, a difference in the softness and manageability of the hair can be noticed after two to four weeks. A complete improvement in hair condition takes longer, as hair grows slowly and damaged hair does not repair itself immediately. Consistency is more important than intensive one-off treatments.
