Three names come up more than any others when people start looking into hair loss treatments: finasteride, minoxidil, and PRP.
Each one works differently, suits different people, and comes with its own set of pros and cons. Understanding how they compare can help you figure out which approach makes the most sense for you.
Let us break down all three options so you can weigh up what matters most.
The Basics: What Each Treatment Does
Finasteride
Finasteride is a daily tablet that blocks the hormone (DHT) responsible for pattern hair loss. By reducing DHT levels, it helps stop follicles from shrinking and can allow them to recover.
It is prescription-only and currently approved for men. Women of childbearing age cannot use it.
Minoxidil
Minoxidil is a liquid, foam, or spray applied directly to your scalp once or twice daily. It works by increasing blood flow to hair follicles, helping them stay active longer and produce thicker hair.
It is available over the counter without a prescription and suitable for both men and women.
PRP (Platelet-Rich Plasma)
PRP uses your own blood to stimulate hair growth. A small sample is taken, spun to concentrate the platelets (which are packed with growth factors), and then injected into your scalp.
Because it uses your own blood, there is no risk of allergic reaction. It is a natural approach that works with your body rather than introducing medication.
How They Compare: The Key Differences
Daily Routine vs Clinic Visits
Finasteride and minoxidil require daily commitment. Miss a few weeks and your progress can slip. For some people, this fits easily into their routine. For others, it becomes something they forget or get tired of doing.
PRP is done periodically at a clinic. You come in for a session, then carry on with your life. No daily applications, no tablets to remember. Some people find this easier to stick with over the long term.
Side Effects
This is where the three treatments differ most.
Finasteride can cause hormonal side effects in some men, including reduced libido and other sexual changes. These affect a small percentage of users, but for those who experience them, it can be a concern.
Minoxidil is applied topically, so side effects tend to be localised: scalp irritation, dryness, itching, or unwanted facial hair growth (particularly in women).
PRP has an excellent safety profile. Because it uses your own blood, there are no systemic or hormonal effects. The most common side effects are mild tenderness or redness at the injection sites, which settles quickly.
If avoiding medication side effects is important to you, PRP offers a genuinely different option.
Who Can Use Them
Finasteride: Men only. Not suitable for women who are or may become pregnant.
Minoxidil: Men and women.
PRP: Men and women.
How Long Until You See Results
All three treatments take time to show visible results. Hair growth is a gradual process, and you should expect to wait around 3 to 6 months before noticing real changes. This is true regardless of which treatment you choose.

Who Suits Each Treatment?
Finasteride may work for you if:
- You are a man with pattern hair loss
- You are comfortable taking daily medication
- You are not worried about potential hormonal side effects
- You want to tackle the root cause (DHT)
Minoxidil may work for you if:
- You want something available without a prescription
- You do not want to take oral medication
- You are a woman experiencing hair loss
- You are happy with a daily scalp application
PRP may work for you if:
- You prefer a natural, non-medication approach
- You want to avoid hormonal side effects
- You do not want a daily routine to remember
- You like the idea of using your body’s own healing ability
- You are in the early to middle stages of hair loss
Can You Combine Them?
Yes, and many people do.
Each treatment works through a different mechanism, so using them together can address hair loss from multiple angles. Some people use PRP alongside minoxidil. Others combine PRP with finasteride for enhanced results.
If you are already using one treatment and want to boost your progress, adding another can help. Equally, if you start with PRP and later want to explore medication, the options remain open.
Why Many People Choose PRP
At Hair Loss Studios, PRP is what we do. Here is why so many of our clients choose it:
No medication side effects
PRP does not affect your hormones. There are no sexual side effects, no mood changes, no systemic impact. For people who want effective treatment without medication, it is the obvious choice.
No daily routine
You come in for periodic sessions rather than remembering to take something every day. For busy people, this is often more realistic long-term.
It is natural
Using your own blood to stimulate hair growth appeals to people who prefer working with their body rather than introducing external substances.
It works well with other treatments
If you are already using minoxidil or finasteride and want better results, PRP can provide that extra boost.
The Bottom Line
There is no single “best” treatment for everyone. The right choice depends on your preferences, your health, and what fits your life.
Some people are happy taking daily medication. Others prefer to avoid it entirely. Some want to combine approaches for maximum effect. There is no wrong answer, just what works for you.
FAQs
Is PRP better than finasteride or minoxidil?
They work differently and suit different people. PRP is a natural, non-medication approach with no hormonal side effects. Finasteride and minoxidil are proven medications that work well for many people but require daily use and can cause side effects in some. The “better” option depends on your priorities.
Can I use PRP instead of medication?
Yes. Many people choose PRP specifically because they want to avoid medication. It is an effective standalone treatment for people in the early to middle stages of hair loss.
Can I combine PRP with finasteride or minoxidil?
Absolutely. Combining treatments often produces better results because each works through a different mechanism. PRP pairs well with both.
Does PRP have fewer side effects?
Yes. PRP uses your own blood, so there are no systemic or hormonal side effects. Finasteride can cause sexual side effects in some men, and minoxidil can irritate the scalp. PRP’s side effects are limited to mild, temporary tenderness at the injection sites.
Which treatment works fastest?
All three take around 3 to 6 months to show visible results. Hair growth is gradual regardless of which treatment you use.
Is finasteride safe for women?
Finasteride is not approved for women of childbearing age due to potential pregnancy risks. PRP and minoxidil are both suitable for women.
What happens if I stop treatment?
With all three treatments, results gradually reverse if you stop. Hair loss is progressive, so ongoing treatment is needed to maintain results.
Not Sure Which Is Right for You?
Choosing a treatment is a personal decision. What suits one person may not suit another.
