How Does Finasteride Regrow Hair?
Finasteride works by targeting a specific enzyme in the body responsible for converting testosterone into dihydrotestosterone (DHT). DHT is notorious for causing hair follicles to shrink, leading to hair loss.
Finasteride decreases DHT levels by inhibiting the enzyme 5-alpha-reductase. This reduction helps with slowing down hair loss and, in some cases, promotes regrowth.
DHT Reduction
When DHT levels decrease, the negative effects on hair follicles are minimized. This change allows the follicles to regain their size and function, potentially leading to thicker and fuller hair over time.
Timeline for Results
While some may notice improvements in as little as 3 months, most users will see significant changes around the 6-month mark. Consistent use can achieve and sustain the best results.

I started using this twice a day because I noticed my hairline receding. Didn’t pay attention to track results, now my stylist told me my hair has grown a lot since my last root touch up. I'm impressed! - Bailey

Finasteride Dosages
Standard Dosage
The typical dosage for treating hair loss is 1 mg per day. This amount has been shown to effectively reduce DHT levels in the scalp, slowing hair loss and promoting regrowth.
Higher and Lower Doses
While 1 mg is the standard, some individuals might be prescribed different doses based on their specific needs. For instance, higher doses like 5 mg are generally used for treating benign prostatic hyperplasia (BPH), not hair loss.
Lower doses might be considered for individuals who are concerned about side effects or are looking for a more conservative approach.
Frequency of Use
Finasteride is typically taken once daily. Skipping doses can lead to fluctuations in DHT levels, potentially hampering the drug's effectiveness.
Side Effects of Finasteride
Common side effects of finasteride include a decreased libido, erectile dysfunction, and, in some cases, a reduction in semen production. These side effects are generally rare and reversible upon discontinuation of the drug.
Less Common Side Effects
While the more common side effects are relatively mild, there are less frequent ones that you should be aware of. Some users have reported experiencing depression, testicular pain, or even allergic reactions like rashes and swelling. Note that these are not typical and occur in a small percentage of users.
Another rare but noteworthy side effect is breast tenderness or enlargement in men. If you notice any unusual changes in your body, consult with your healthcare provider immediately.
What to Do If You Experience Side Effects

Consult your physician immediately if you experience any side effects when taking finasteride.
If you experience any side effects, speak with your healthcare provider to discuss your symptoms and potential alternatives. You should also monitor your symptoms by keeping a log of any changes you experience so you can relay such information to your doctor.
Your doctor may recommend adjusting your dosage to see if it alleviates the side effects or can suggest other treatment options for you.
Who Should Avoid Finasteride?
While finasteride is effective for many, it's not suitable for everyone. Certain individuals should avoid using it due to potential health risks or interactions with other conditions.
Health Conditions to Consider
Individuals with liver disease should be cautious when considering finasteride. The liver metabolizes the medication, and any impairment could affect how the body processes the drug, leading to an increased risk of side effects.
Also, those with a history of prostate cancer or high PSA levels should consult their healthcare provider before starting finasteride. The drug can affect PSA levels, which are used to screen for prostate cancer.
Pregnancy and Finasteride

Pregnant women should avoid taking or even handling finasteride.
Pregnant women should not use or even handle crushed or broken Finasteride tablets. The active ingredient in finasteride can be absorbed through the skin and may harm a developing fetus, particularly male fetuses, due to its effects on hormone levels.
Therefore, women who are pregnant or may become pregnant should exercise caution and avoid contact with the medication to prevent any potential risks to their unborn child.
Other Medications to Avoid
Combining Finasteride with certain medications can lead to interactions that may affect its efficacy or increase the risk of side effects. For instance, some blood thinners and medications that affect hormone levels may not be compatible with Finasteride.
If you're taking other medications, inform your healthcare provider to ensure there are no adverse interactions that could compromise your health or the effectiveness of your treatment.
Why Natural Remedies Might be Better
Fewer Side Effects
Natural remedies often have a lower risk of adverse reactions, making them a safer choice for many individuals.
Unlike pharmaceuticals, natural treatments typically don't carry the same risk of side effects. This can make them a more appealing option especially if you are sensitive to medications or prefer a more holistic approach.
Natural Ingredients
Natural remedies often harness the power of plant-based ingredients known for their beneficial properties.

Rosemary oil is one ingredient that can help support your hair growth.
Ingredients like rosemary oil, saw palmetto, and biotin are popular choices that can support hair health.
These ingredients work synergistically to nourish the scalp, strengthen hair follicles, and promote overall hair vitality.
Holistic Health Benefits
Natural remedies offer more than just hair benefits—they can also support your overall health and well-being. Many natural ingredients have antioxidant, anti-inflammatory, and nourishing properties that contribute to a healthier lifestyle.
Common Natural Alternatives
There are different natural alternatives that individuals can try out as part of their hair care routine. These include:
- Saw Palmetto: Can block DHT, similar to Finasteride, but with fewer side effects.
- Biotin: A vitamin that supports hair strength and growth.
- Rosemary Oil: Often used to stimulate hair growth and improve scalp circulation.
- Ginseng Extract: Revitalizes natural hair growth.
- Castor Oil: Increases blood circulation to the scalp
Trying out these alternatives can provide additional options for those seeking a more natural approach to hair care.
