Finasteride vs Minoxidil: Which Is Suitable For You?

Finasteride vs Minoxidil

Did you know that half of the men worldwide experience hair loss by age 50? About 25% of bald men see the first signs of hair loss before turning 21. And about 70% of men lose their hair as they get older. However, modern science is constantly trying to find solutions due to its advancements. There are two popular medicines, Finasteride and Minoxidil, available in the market for hair loss.

Finasteride belongs to the 5-alpha-reductase inhibitors class of drugs. In comparison, Minoxidil belongs to the antihypertensive vasodilator class of drugs. The US FDA approved Finasteride for male pattern hair loss in 1997.

Only the liquid form of Minoxidil is used to treat hair loss (the active ingredient in the brand Rogaine). Minoxidil (5% w/v) was approved by the FDA for androgenetic alopecia (AKA male-pattern baldness) in 1988 and later in 1992 for female-pattern hair loss (2% w/v).

Age Restrictions

Finasteride is only authorised for men 18 years of age and older. It is not indicated for use in women or children. Minoxidil is approved for people 18 years of age or older. People aged 65 are usually not given this medicine.

Availability and Cost

Finasteride is a prescription-only medicine readily available at local and online pharmacies. In the US, 5 mg of finasteride costs around $12, with 30 tablets. While in the UK, the cost of 28 tablets for the same strength is £4.26. Minoxidil is an over-the-counter medicine readily available at local and online pharmacies. In the US, Minoxidil topical 5% solution of 60 grams ranges from $15 to $20. Depending on the pharmacy of your choice, the prices may vary. While in the UK the cost is about £20.

They Are Prescription Or OTC

Finasteride is a prescription-only medication, while Minoxidil is available without a prescription over-the-counter. Both these medications are very readily available at local and online pharmacies.

Form and Dosage

Finasteride comes in the form of tablets only. This medication comes in 2 strengths- 1 mg and 5 mg. The recommended daily dose for hair loss is 1 mg. Minoxidil tablets are not approved for the treatment of hair loss. The liquid solution (sold under the brand name Rogaine) is approved for hair loss. A topical solution is available in a 2% and 5% strength. The topical foam comes in 5% strength. It is advised to apply the medication to the hair once or twice a day.

Can Finasteride and Minoxidil Regrow Hair?

Finasteride works by inhibiting testosterone conversion to dihydrotestosterone (DHT). This medication may not drastically change your hair’s growth and quality; however, many people have noticed good hair regrowth after this medication. 

Minoxidil (Rogaine) works by increasing the blood flow to the hair follicles. This results in an increased follicular size and hair shaft diameter that helps stimulate hair growth. This medication is best used when early signs of hair loss or a receding hairline occur. Both these medications stop hair loss and promote hair regrowth. However, not all who use it can see the same results.

How to Take Them?

You must follow your doctor’s advice when using Finasteride. Your doctor will prescribe you a dosage suitable for you. Finasteride is typically taken with or without food. It usually takes three months for the medication to work- but it can take longer and varies from person to person. It would be best to follow the directions mentioned in the information leaflet on the medicine. If you are questions or are concerned about your medication, you should speak with your healthcare provider. 

For Minoxidil, apply the amount mentioned in the information guide or as prescribed by your doctor on a dry scalp. Allow the medication to dry for 2 to 4 hours. Avoid watching your hair with a shampoo for 4 hours after using Minoxidil.
