Effective Hair Loss Treatments

Understanding hair loss: why it happens

Hair loss, or alopecia, can occur due to genetics, stress, medical conditions, or lifestyle factors. The most common cause in men is male pattern baldness (androgenetic alopecia), triggered by sensitivity to the hormone dihydrotestosterone (DHT). Over time, DHT shrinks hair follicles, leading to thinner strands and eventual hair loss.

Common causes include:

• Genetic predisposition

• Hormonal changes

• Stress (linked to conditions like telogen effluvium)

• Nutritional deficiencies (iron, zinc, vitamin D)

• Certain medications

Hair loss often begins with a receding hairline or thinning at the crown. Early treatment can slow progression and improve outcomes.

Hair loss affects millions of people in the UK. Learn more about causes, types, and treatments on the official NHS Hair Loss Guide.

Symptoms and signs of hair loss

Recognising early signs can help you seek treatment sooner. Watch for:

• Gradual thinning on top of the head

• A receding hairline forming an “M” shape

• Sudden loosening of hair, especially during brushing or washing

• Patches of circular bald spots

If you notice rapid or unexpected hair loss, consult your GP to rule out underlying health conditions.

How do treatments work?

Finasteride works by blocking the enzyme that converts testosterone into DHT — the main culprit behind male pattern hair loss. Lower DHT levels mean less follicle shrinkage, preserving hair density.

Minoxidil, on the other hand, helps by widening blood vessels in the scalp, improving circulation, and extending the hair’s growth cycle. This means thicker hair and reduced shedding.

Consistency is key: stopping treatment will typically result in hair loss resuming.

How long until I see results?

Hair regrowth is gradual. Expect:

• 3–6 months for noticeable improvement with Finasteride or Minoxidil.

• 6–12 months for optimal results.

• Continued use is necessary to maintain gains.

Supporting hair growth: lifestyle tips

Enhance your treatment by:

• Eating a balanced diet rich in protein, iron, and vitamins C and D.

• Reducing stress with techniques like mindfulness or yoga.

• Avoiding harsh hair treatments or heat styling.

• Using gentle shampoos and conditioners.

When to see a GP

Consult your doctor before starting treatment if:

• Hair loss is sudden or patchy.

• You have a family history of autoimmune disorders.

• You experience scalp inflammation, pain, or unusual symptoms.

Your GP can help diagnose the underlying cause and refer you if needed.

FAQs

How long do I need to take hair loss treatments?

As long as you wish to maintain results. Discontinuation leads to hair loss resuming.

Is hair loss treatment safe?

For most people, yes. Side effects like reduced libido or scalp irritation are uncommon but possible. Always discuss with your prescriber.

Can women use these treatments?

Minoxidil is approved for female pattern hair loss, but Finasteride should not be used by women.

Does stress cause hair loss?

Stress can contribute to shedding (telogen effluvium), but male pattern baldness is primarily genetic.
