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

Short answer: Dry hair occurs when the cuticle loses moisture due to harsh products, sun exposure or a poor diet. With gentle care and the right nutrients, dry hair can usually be effectively improved.

Dry hair is a problem that many men recognise but rarely take seriously. The hair feels stiff, has lost its shine and breaks more easily than usual. However, there are specific steps you can take, from choosing the right shampoo to your daily diet. In this article, you’ll find out what causes dry hair, how to recognise it and what you can actually do about it.

What exactly is dry hair?

Dry hair occurs when the natural oils from the scalp no longer reach the hair properly. The sebaceous glands in your scalp produce sebum: an oily substance that coats and protects the hair shaft. When this supply is insufficient or disrupted, the hair’s outer protective layer – the cuticle – loses its moisture.

The cuticle scales open up, allowing moisture to escape from the hair and leaving it vulnerable. Research into hair structure shows that an intact cuticle is essential for the hair’s elasticity and shine.

What causes dry hair in men?

The most common cause is washing too frequently with a shampoo containing harsh cleansing agents. Sulphates, which are found in many common shampoos, strip the hair shaft of its natural oils. In addition, environmental factors play a major role: prolonged exposure to sun, wind or dry air damages the hair fibre. Dermatological research shows that UV radiation directly damages the protein structure of the hair.

Chemical treatments such as permanent colouring or bleaching also increase the hair’s porosity, causing it to dry out more quickly. Finally, an unbalanced diet contributes to dry hair: a deficiency in fluids, proteins or essential fatty acids leaves its mark on the hair fibre.

How can you recognise dry hair?

Dry hair feels rough or coarse, even immediately after washing. It loses its shine and looks dull and lifeless. Frizz is a common side effect, as are split ends that break off easily when combing.

If your hair is difficult to style and quickly becomes static, this is also a sign that the moisture balance is disrupted. Most men will recognise these signs, and fortunately, they respond well to targeted care.

What really helps with dry hair?

The basis is a mild, sulphate-free shampoo that cleanses the hair without completely stripping away its natural oils. Cosmetological research shows that nourishing conditioners and hair masks can smooth the cuticle and restore the moisture content of the hair fibre. Use a moisturising mask once or twice a week and, ideally, let your hair air-dry.

If you do use a hairdryer, set it to a low heat setting and keep it at a distance from your hair. A small amount of argan oil on the ends helps retain moisture without making the hair greasy. Consistency is key here: a one-off intensive treatment is less effective than a regular daily routine.

Does diet also play a role in dry hair?

Diet plays a bigger role than many men realise. Hair consists largely of keratin, a protein that needs to be produced continuously. Research into diet and hair growth shows that deficiencies in protein, zinc, iron and B vitamins are directly reflected in the quality of the hair.

Omega-3 fatty acids, found in foods such as oily fish and walnuts, support sebum production and help keep the hair hydrated. A diet rich in unprocessed protein sources, vegetables and healthy fats lays a solid foundation for healthy hair.

When is dry hair more than just a styling issue?

In most cases, dry hair is simply a styling issue, but persistently brittle or thinning hair can also be an early sign of something else. Hormonal changes, particularly a rise in dihydrotestosterone (DHT), can cause hair to miniaturise and become brittle. Prolonged stress is also a well-known factor: read more about stress-related hair loss and how it affects the hair growth cycle.

The NHG, the professional association of Dutch GPs, identifies several causes of hair-related complaints that require a targeted approach.

Frequently asked questions about dry hair in men

Why is my hair so dry, even though I wash it regularly?

Washing too frequently is actually a common cause of dry hair. Shampoos containing sulphates cleanse aggressively and remove not only dirt but also the natural oils that protect the hair. Washing less frequently and switching to a mild shampoo often resolves this issue.

Can dry hair lead to hair loss?

Dry, brittle hair can snap off, which looks like hair loss but technically isn’t. However, persistent dry hair can be a sign of hormonal or nutritional causes that may also lead to hair loss. If in doubt, an online consultation with Fellos is a good first step.

Does a hair mask help with dry hair in men?

Yes. A moisturising hair mask used once or twice a week restores the moisture levels of the hair fibre and smooths the cuticle. Choose a mask containing keratin, argan oil or shea butter for the best results.

Is dry hair a sign of a vitamin deficiency?

It can be. Deficiencies in zinc, iron, vitamin B7 (biotin) or omega-3 fatty acids are known causes of dry and dull hair. A varied diet with sufficient protein and vegetables forms the basis of healthy hair.

When should I see a doctor about dry hair?

If, as well as dry hair, you also notice that your hair is becoming thinner, you’re experiencing increased hair loss or you’ve noticed bald patches, it’s wise to consult a doctor. Fellos offers an online consultation where a Dutch doctor will assess your situation and provide advice.
