Male pattern hair loss is progressive, and the single biggest factor in how much hair you keep is how early you start. At Slender Me Medical in Corona, our Hair Restoration Program uses the two treatments with real evidence behind them — with proper monitoring, and honest conversation about the tradeoffs.
Why Hair Loss Happens
Male pattern baldness is driven by dihydrotestosterone, or DHT, a hormone your body converts from testosterone. In men with the genetic sensitivity, DHT gradually shrinks hair follicles until they stop producing visible hair.
The process is slow and one-directional. Follicles that have been dormant for years generally cannot be revived. This is why timing matters more than anything else — treatment protects what you still have far more effectively than it recovers what is gone.
Not all hair loss is genetic, though. Thyroid disease, iron deficiency, stress, certain medications and some autoimmune conditions all cause shedding, and they are treated completely differently. We check before assuming.
What We Use
Finasteride
A daily tablet that blocks the conversion of testosterone to DHT, reducing the hormone driving the loss. It is FDA-approved for male pattern hair loss and is the most effective medication available for slowing it.
Most men see shedding slow within three to six months. Some regrow hair; more commonly, it holds the line. Results require continuous use — stopping means losing the benefit within six to twelve months.
Topical minoxidil
Applied to the scalp twice daily. It works differently from finasteride, improving blood flow to the follicle and extending the growth phase. It is FDA-approved and available without prescription.
The two work well together because they address different parts of the same process. Men using both generally do better than men using either alone.
Oral minoxidil
Oral minoxidil is not FDA-approved for hair loss. It was developed as a blood pressure medication, and the hair growth was discovered as a side effect. Prescribing it in low doses for hair loss is off-label — lawful, increasingly common, and supported by growing evidence, but you should know that going in.
It suits men who find the topical solution messy, who react to it, or who have not responded to it. Because it acts throughout the body rather than just on the scalp, it requires blood pressure monitoring and can cause hair growth in unwanted places.
The Conversation Most Clinics Skip
Finasteride can cause sexual side effects — reduced libido, erectile difficulty, or changes in ejaculation. In clinical trials this affected a small percentage of men, and it typically resolves after stopping. Some men report symptoms persisting longer, and while this remains debated in the literature, you deserve to hear it before you start rather than after.
We raise this at the first visit, not the third. If you are already dealing with erectile difficulty, that changes the conversation about whether finasteride is the right choice for you, and in what order we approach things.
This is also why treating men’s health as one connected picture matters. An online service will sell you finasteride on one page and erectile dysfunction medication on another and never mention that the first can contribute to the second. We see the whole patient, and if something changes after starting treatment, you tell us and we adjust.
In-Office or Telehealth
Neither medication is a controlled substance, so we can treat you in person at our Corona clinic or by telehealth in the states where we are licensed. Tell us where you live and we will confirm what we can do.
An in-person look at your scalp is genuinely useful at the start — the pattern of loss tells us whether this is male pattern baldness or something else entirely, and photographs taken properly give you a real baseline to judge progress against. After that, ongoing management by telehealth works well.
Important Safety Information
Finasteride can cause birth defects. Women who are or may become pregnant must not handle broken or crushed tablets. Whole tablets are coated and safe to handle.
Finasteride lowers PSA levels by roughly half. This matters for prostate cancer screening — any provider interpreting your PSA needs to know you take it. We account for this in your monitoring.
Other possible effects include breast tenderness or enlargement, and mood changes. Report any breast lump, pain or discharge promptly.
Minoxidil can cause scalp irritation and unwanted facial hair growth. The oral form can lower blood pressure, cause fluid retention, and increase heart rate; it requires monitoring and is not suitable for men with certain cardiac conditions.
Both treatments cause temporary increased shedding in the first weeks. This is expected — older hairs releasing as new growth begins — and is not a reason to stop.
This page is general information, not medical advice. What is appropriate for you is decided at your consultation.
What to Expect
- Months 0–1: possible increased shedding. Normal. Do not panic.
- Months 3–6: shedding slows. This is the first real sign it is working.
- Months 6–12: visible thickening in men who are going to respond.
- Ongoing: continued use maintains the result. Stopping reverses it.
Take photographs at the start. Daily change is invisible; twelve-month change usually is not, and memory is unreliable.
