Male hair loss — causes and treatment options

Male hair loss (androgenetic alopecia) is the most common form of hair loss in men. It affects up to 80% of men at some point in life, often starting in their 20s or 30s. What causes it? The cause is a combination of two factors: genetics and the hormone DHT (dihydrotestosterone). The follicles in the forehead and crown are genetically more sensitive to DHT, which slowly shrinks them until they stop producing hair. By contrast, the follicles at the back and sides of the head are genetically resistant — and keep growing for life. Treatment options 1. PRP treatment — halts the hair loss and densifies existing hair 2. Minoxidil — over-the-counter lotion that stimulates hair growth 3. Finasteride — prescription tablet that blocks DHT 4. Hair transplant — permanent relocation of healthy follicles When is the right time? Ideally when the hair loss has stabilised (usually after 25) and when PRP or medication is not enough. We make a free assessment of your scalp at the consultation.

Frequently asked questions about hair loss

What is the most common cause of male hair loss?

Androgenetic alopecia (genetic pattern hair loss) accounts for about 95% of cases. It is caused by the follicles being hypersensitive to DHT (dihydrotestosterone). Stress, diet and hormones can affect the pace but rarely the root cause.

Can male hair loss be stopped?

Progression can be slowed or stopped with Finasteride (lowers DHT) and Minoxidil (stimulates growth). 80–90% see an effect within 12 months. Hair lost where the follicles have died can only be restored with a transplant.

When should I seek help for hair loss?

As soon as you notice a clear recession at the temples or thinning on the crown. Early intervention with PRP or medication can preserve more of your existing hair and postpone the need for a transplant.
