Not everyone will experience male pattern baldness, and genetics is the main reason why some men see thinning while others keep a thick head of hair into later life. While stress, nutrition and illness can influence shedding, your genetic makeup is the biggest factor in when—and how much—hair you may lose.
At McGorisks Pharmacy, we stock targeted solutions to help you take control early, support scalp health and preserve hair density. If you’re noticing changes, it’s worth acting now.
Hair Loss and Genetics
For most men, hair loss is driven by androgenetic alopecia (male pattern hair loss). This inherited sensitivity affects hair follicles over time, leading to progressively finer hairs and a receding hairline or thinning at the crown. If close relatives experienced pattern hair loss, there’s a higher chance you may too.
Genetic predisposition doesn’t mean you have to accept rapid progression. Early, consistent care can slow shedding, improve scalp conditions for growth and help maintain the hair you have.
How DHT Fits In
A hormone called dihydrotestosterone (DHT) plays a key role in genetic hair loss. In genetically susceptible follicles, DHT shortens the growth phase and miniaturises hairs. Over time, this can result in visible thinning. Managing DHT at the scalp—alongside good scalp care and nutrition—forms the backbone of most effective routines.
Clinically Proven Treatment Options
Finasteride (Rx) helps by inhibiting the 5α-reductase enzyme that converts testosterone to DHT. By reducing scalp DHT, it can slow or halt further loss in many men with male pattern hair loss. In Ireland, finasteride is prescription-only; speak to your GP or pharmacist for guidance.
Minoxidil (topical) supports follicles by improving blood flow and oxygen delivery to the scalp environment. With consistent use, many users notice reduced shedding and improved density over time. Minoxidil solutions and foams are widely available.
For best results, people often combine daily scalp care (cleansing and targeted shampoos), nutritional support (e.g., biotin or hair-health complexes) and proven treatments. Consistency is key—give any new routine at least 3–6 months.
