Hair loss is one of the most common aesthetic and medical concerns affecting both men and women. In androgenetic alopecia (pattern hair loss), two of the most studied and widely used treatments are Minoxidil and Finasteride.
Although they’ve been used for decades, many people still have questions about:
- who these treatments are suitable for
- how they work
- how effective they are
- what side effects may occur
Let’s break everything down clearly.
What is Minoxidil?
Minoxidil is a pharmaceutical ingredient applied to the scalp (as a lotion/solution, foam, or in some cases orally) and is used in both men and women.
How does Minoxidil work?
Minoxidil:
- improves microcirculation in the scalp
- prolongs the anagen (growth) phase of the hair cycle
- supports follicle nourishment
- can contribute to thicker hair shafts
Minoxidil results: what to expect
Minoxidil results are not immediate. Typically:
- after 3–4 months, many people notice stabilisation of shedding
- around 6 months, visible improvement may begin
- by 9–12 months, response can be fully assessed
Results depend on:
- the stage of hair loss
- consistency of use
- genetic predisposition
Minoxidil requires ongoing use. If you stop, hair loss often gradually returns.
What are the possible side effects of Minoxidil?
Minoxidil side effects are generally mild and localised. The 5 most common include:
- scalp dryness
- itching
- mild flaking (similar to dandruff)
- mild redness
- temporary increased shedding at the start of treatment (“shedding phase”)
Side effects rarely require stopping treatment and often improve with correct guidance.
What is Finasteride and how does it work?
Finasteride is mainly used for male androgenetic alopecia and works by reducing levels of dihydrotestosterone (DHT)—the hormone responsible for progressive follicle miniaturisation.
How is Finasteride prescribed?
Finasteride may be prescribed:
- orally (tablet form)
- topically (in specialised formulations)
Topical Finasteride is applied directly to the scalp and is intended to minimise systemic absorption, acting primarily locally on the scalp.
The best option depends on:
- medical history
- individual tolerance
- the treating doctor’s assessment
Finasteride is also an FDA-approved medication for androgenetic hair loss.
Finasteride results: how effective is it?
Finasteride results mainly involve:
- slowing progression of hair loss
- stabilising androgenetic alopecia
- in some cases, improving density
Initial assessment is usually after 3–6 months, while full evaluation typically needs around 12 months of continuous treatment.
What are the possible side effects of Finasteride?
Finasteride side effects are relatively uncommon, but may include:
- reduced libido
- erectile dysfunction
- reduced ejaculatory volume
In most cases, side effects are mild and reversible after discontinuation.
Finasteride is not recommended for women of reproductive age or during pregnancy.
Can Minoxidil and Finasteride be used together?
Yes. Combination treatment can offer a more comprehensive approach:
- Finasteride targets the hormonal cause (DHT)
- Minoxidil stimulates follicle activity and growth
Combination therapy should only be recommended after an individual medical diagnosis.
Can Minoxidil and Finasteride be used for beard growth?
Yes—Minoxidil is used off-label for beards, and there are clinical reports suggesting it may support facial hair growth. However, it must be used correctly, as it can cause irritation/dryness and other unwanted effects (e.g., early “shedding”).
By contrast, Finasteride is not a treatment designed for beard growth (its goal is to reduce DHT for scalp hair loss). It is not specifically recommended for beards, and in some cases there is a theoretical concern that lowering DHT may affect facial hair growth—so medical guidance is essential.
Comprehensive hair loss treatments for women and men
For a more complete approach to hair loss, there are additional options beyond medication. Seneca Medical Group uses tailored protocols that may include specialised shampoos and lotions, supplements, and supportive treatments designed to improve overall scalp health—adapted to each individual’s needs.
Can PRP be combined with Minoxidil or Finasteride?
In many cases, medical therapy can be enhanced with PRP for hair (Platelet-Rich Plasma)—a non-surgical treatment that uses growth factors from the patient’s own blood.
PRP:
- stimulates follicle activity
- improves microcirculation in the scalp
- may enhance the results of Minoxidil or Finasteride
PRP is applied in a personalised way and is often recommended either as a complementary solution or as an intermediate step before more invasive options.
How to improve hair density with natural methods
Alongside medical treatments, natural approaches can also support hair density and scalp health. Factors such as a nutrient-rich diet, supportive oils, quality sleep, and proper hair care can contribute to healthier-looking, fuller hair.
When medical treatments are not enough
In advanced stages—when follicles have fully atrophied—medical treatments cannot restore follicles that are no longer functioning. In these cases, hair transplant surgery may be the only permanent solution.
Why accurate medical diagnosis mattersChoosing between:
- Minoxidil 2% vs 5%
- topical vs oral Finasteride
- or combination treatment
should only be done after specialist assessment.
