Who qualifies for finasteride or dutasteride
Our EU-licensed doctors individually review every case to ensure finasteride or dutasteride is safe and appropriate for you. They will assess your medical history, current health status, and the specific pattern of your hair loss. Generally, these medications are prescribed for androgenetic alopecia (male or female pattern baldness). The doctor looks for indicators such as a receding hairline, thinning on the crown, or diffuse thinning. Essential considerations include your age, any pre-existing conditions, and medications you are currently taking. You must be over 18 years old. The doctor's primary concern is your safety and the effectiveness of the treatment.
What finasteride or dutasteride actually does (and doesn't do)
Finasteride and dutasteride are 5α-reductase inhibitors. This means they block the enzyme 5-alpha reductase from converting testosterone into dihydrotestosterone (DHT). DHT is the primary hormone responsible for shrinking hair follicles, leading to hair loss. By reducing DHT levels, these medications can slow down, stop, or even reverse hair loss in many individuals. You can expect to see initial results, such as reduced shedding, within 3-6 months. Significant hair regrowth can take 6-12 months or longer. It's important to understand that these medications work best for preventing further hair loss and promoting regrowth in existing, albeit miniaturised, follicles. They do not create new hair follicles where none exist. Consistency is key for optimal results.
Side effects and when to stop
Like all medications, finasteride and dutasteride can have side effects. Common side effects may include decreased libido, erectile dysfunction, and ejaculatory disorders. Less common but possible side effects include breast tenderness or enlargement. These side effects are usually reversible upon stopping the medication. It's crucial to discuss any concerns with your doctor. If you experience severe side effects such as allergic reactions, depression, or changes in breast tissue, you should stop the medication and seek immediate medical attention. Our doctors provide clear guidance on what to watch for and when to discontinue treatment.
