What is the main cause of hair loss in men?

The most common cause is androgenetic alopecia, also called male pattern hair loss. It is driven by a combination of genetic predisposition and sensitivity to DHT, a hormone derived from testosterone. DHT causes genetically susceptible follicles to miniaturise gradually over time, producing finer and shorter hairs until the follicle becomes inactive. The NHS estimates it affects around half of men by age 50.

Does DHT cause all male hair loss?

DHT sensitivity is the main driver of male pattern hair loss, but it is not the only cause of hair thinning in men. Nutritional deficiencies (particularly iron, zinc, vitamin D and B vitamins), thyroid conditions, high stress, scalp conditions like seborrhoeic dermatitis, and certain medications can all contribute to increased shedding. If your hair loss is sudden or patchy, it is worth seeing a GP to rule out other causes.

Can supplements help with male hair loss?

Supplements can support the nutritional foundations that normal hair growth depends on. Nutrients like zinc, iron, biotin, and B vitamins play a role in healthy hair cycles, and deficiencies in these are associated with increased shedding. Ingredients like Saw Palmetto and Pumpkin Seed have attracted research interest for their potential influence on DHT activity at the follicle. Supplements are not a magic fix, but they are a sensible part of a broader approach, especially if your diet leaves gaps.

What is microneedling and does it help hair loss?

Microneedling (or derma stamping) uses fine needles to create tiny micro-channels in the scalp. The mechanical process is thought to stimulate the scalp's natural response and may support the environment around hair follicles. It is typically used alongside supplements and topicals rather than as a standalone approach. Adjustable devices, like the Dense Scalp Activator Derma Stamp, let you start at a lower depth and build up gradually.

Are there prescription treatments for male hair loss in the UK?

Yes. There are licensed prescription treatments available in the UK for male pattern hair loss. A pharmacist or GP can assess whether they are appropriate for you based on your health history and the extent of your hair loss. Dense Hair Experts, the pharmacy behind Dense, offers pharmacist-led consultations and prescription pathways alongside everyday supplements and topicals, so you can access the full range of options in one place.

When should I see a GP about hair loss?

See your GP if your hair loss came on suddenly, appears in patches, is accompanied by other symptoms like fatigue, skin changes or scalp soreness, or if you suspect a medication might be causing it. A blood test can check for nutritional deficiencies and thyroid issues. For general guidance on supplements or to explore prescription options, a pharmacist is a good first step and no GP referral is needed.

Does starting early make a difference to hair loss?

Generally, yes. Hair follicles that are still active and producing hair, even if finer than before, are easier to support than follicles that have been dormant for a long time. Starting a joined-up approach earlier means there is more to work with. This does not mean it is too late if you have been losing hair for years, but earlier action does tend to produce better results.

Is male hair loss the same as female hair loss?

No, they are different in pattern and often in cause. Male pattern hair loss typically follows a recognisable progression of a receding hairline and crown thinning, driven primarily by DHT sensitivity. Female hair loss more often presents as a diffuse thinning across the top of the scalp and is more frequently linked to hormonal changes, nutritional deficiencies or conditions like polycystic ovary syndrome. The underlying biology overlaps in places, but the approach to each is distinct.

Can I use a shampoo every day without damaging my scalp?

Yes, provided you use a shampoo that is formulated for daily use. Harsh cleansers can strip the scalp's natural oils and disrupt its balance, which is counterproductive. A gentle, scalp-balancing formula designed for everyday use, like the Dense Daily Densify 2in1 Shampoo and Conditioner, cleanses without over-stripping and delivers actives like Curcuma, Panax Ginseng and Arginine to the scalp at the same time.

How long does it take to see results from a hair care routine?

Hair grows slowly, typically around 1 to 1.5 centimetres per month, and the growth cycle means changes in the follicle take time to become visible at the surface. Most people who follow a consistent routine notice a difference after three to six months. It is important to be patient and consistent rather than switching products every few weeks, which makes it hard to know what is actually working.

Men's Hair Loss: Causes and What Helps

Male hair loss is incredibly common, and while nothing is a magic fix, there is a lot you can do to support your hair and scalp, especially if you start paying attention early. This guide covers what is actually happening when hair thins, what the evidence points to, and how a joined-up approach tends to work better than any single product on its own.

Why do men lose their hair?

The most common cause is androgenetic alopecia, usually called male pattern hair loss. It affects around half of men by the age of 50, according to the NHS. It is driven by a combination of genetics and sensitivity to a hormone called DHT (dihydrotestosterone), which is a byproduct of testosterone.

DHT binds to receptors in genetically susceptible hair follicles and, over time, causes them to miniaturise. Each hair grows back a little finer and shorter than the last, until eventually the follicle stops producing visible hair. This process is gradual, which is why many men do not notice it happening until there is already a noticeable change.

What does male pattern hair loss actually look like?

The two most recognisable patterns are a receding hairline at the temples and thinning at the crown. These can happen separately or together. The Norwood Scale is the standard way clinicians describe the progression, from a barely-there recession all the way to extensive loss across the top of the scalp.

It is worth knowing that the sides and back of the head tend to stay fuller for longer, because those follicles are less sensitive to DHT. That is why hair transplants move hair from those areas to the top.

Are there other causes of hair loss in men?

Yes, and it is worth ruling them out. Nutritional deficiencies, particularly in iron, zinc, vitamin D and B vitamins, are associated with increased hair shedding. Stress, thyroid issues, scalp conditions like seborrhoeic dermatitis, and certain medications can all play a role too.

If your hair loss came on suddenly, is patchy, or you have other symptoms alongside it, a GP visit is the right first step. A simple blood test can pick up many of the underlying causes.

What genuinely helps with male hair loss?

Honest answer: a combination of approaches tends to work better than one thing alone. Think of it as an inside-out strategy, supporting the follicle from the bloodstream, the scalp surface, and mechanically, all at once. Earlier action is generally more useful than waiting, because it is easier to support a follicle that is still active than to try to wake one that has been dormant for years.

Nutrition and supplements

Hair is made of keratin, a protein, and the follicle is one of the most metabolically active structures in the body. It needs a steady supply of micronutrients to do its job. Zinc, iron, biotin and B vitamins all play a role in normal hair growth cycles, and a shortfall in any of them can affect the quality and quantity of hair you produce.

Saw Palmetto and Pumpkin Seed are two plant-based ingredients that have attracted genuine research interest in the context of male hair. They are thought to work by influencing DHT activity at the follicle, though the evidence is still building and neither is a replacement for licensed treatments. The Dense Daily Densify Hair Vitamins bring these together with Biotin, Zinc, Iron and a full B-vitamin complex in a single daily capsule, so you are not juggling multiple separate supplements.

If you want to understand how to choose a hair supplement that is actually worth taking, the Dense guide to the best hair growth vitamins in the UK is a good place to start.

Scalp-active topicals

Your scalp is skin, and the condition of that skin matters for the follicles sitting beneath it. A scalp that is inflamed, congested or out of balance is not an ideal environment for healthy hair growth. A good daily shampoo should cleanse without stripping, and ideally deliver actives that support scalp health at the same time.

The Dense Daily Densify 2in1 Shampoo and Conditioner is built around Curcuma, Panax Ginseng, Arginine and vitamins B3 and B5. These are named, researched ingredients rather than a vague blend, and the formula is designed for daily use without disrupting the scalp's natural balance. For days when you want to add texture and keep the actives going between washes, the Active Densify Salt Spray uses the same active stack as a leave-in.

Microneedling for the scalp

Microneedling, or derma stamping, involves creating tiny micro-channels in the scalp using fine needles. The mechanical process is thought to stimulate the scalp's natural response and may support the environment around hair follicles. It is increasingly used alongside other approaches rather than as a standalone.

The Dense Scalp Activator Derma Stamp is adjustable from 0 to 3mm, so you can start gently and build up. It contains no actives, it is purely mechanical, and it is designed to fit into a routine alongside topicals and supplements rather than replace them.

Pharmacist-led and prescription options

For some men, over-the-counter supplements and topicals are not enough on their own, and that is completely normal. There are licensed prescription treatments for male pattern hair loss available in the UK, and a pharmacist or GP is the right person to assess whether they are appropriate for you.

What makes Dense different from most hair brands is that there is a pharmacy behind it, Dense Hair Experts, so if your needs go beyond everyday supplements and topicals, a pharmacist-led consultation and prescription pathway is available in the same place. You do not have to start over with a completely different provider. The full Dense range is built as a complete system, from daily nutrition to scalp care to clinical options, personalised to the individual rather than one-size-fits-all.

When should you see a GP or pharmacist?

See your GP if your hair loss came on suddenly, is patchy or asymmetrical, is accompanied by other symptoms like fatigue or skin changes, or if you are concerned it might be caused by a medication you are taking. A blood test is a straightforward way to check for nutritional deficiencies or thyroid issues that could be contributing.

A pharmacist is a good first port of call if you want guidance on supplements or topicals, or if you want to explore whether a prescription treatment might be appropriate. You do not need a GP referral to speak to a pharmacist.

A realistic picture

It is worth being honest with yourself here. No supplement, shampoo or device will bring back a full head of hair if the follicles have been dormant for years. What a joined-up approach can do is support the follicles you still have, nourish the scalp environment, and give your hair the best conditions to do what it naturally can.

Earlier action tends to produce better results, simply because there is more to work with. If you have noticed changes in your hair, now is a reasonable time to start paying attention, rather than waiting to see how much further it goes.
