If you’re on social media, you’ve probably seen ads for hair loss treatments. The pitch is simple: sign up online, get treatments delivered to your door with instructions. It seems easy — and for some, it looks like a cheaper alternative to aesthetic clinics. But is it really?

WHAT ARE IN THESE HAIR LOSS MEDICATIONS?
Many of these services offer a combination of 2 types of medications—a 5α-reductase inhibitor and an antihypertensive vasodilator.
5α-reductase inhibitor is an approved medication to treat male pattern hair loss or androgenetic alopecia.
- It works by lowering the levels of dihydrotestosterone (DHT), the hormone responsible for male pattern hair loss.
- It slows the balding process and, in some patients, hair regrowth may occur.
Antihypertensive vasodilator is commonly dispensed as a topical medication.
- It is applied onto the affected area, not ingested, to facilitate efficient drug delivery into hair follicles.
- It mainly works by increasing blood flow and circulation in the scalp.
- It also helps to improve cell proliferation and increase DNA synthesis for better hair growth.
SOUNDS GOOD, SO WHAT’S THE CATCH?
5α-reductase inhibitor should be prescribed only by a doctor, as there are serious side effects that are associated with these drugs.
- For example, it can decrease one’s libido and affect the functions of the heart and liver in people with certain pre-existing health conditions.
- Traces of this medication can be found in the user’s semen, which can affect the normal development of a baby’s sex organs. Thus, this medication may not be the best option for a man that also intends to have a child.
- Simply put, 5α-reductase inhibitor is a potent drug which must be taken with a doctor’s supervision and counselling, especially as adjustment of dosage is required for long-term use.
Antihypertensive vasodilator is applied topically, so it has less serious side effects compared to 5α-reductase inhibitor.
- However, there are still side effects that can arise from its use, such as inflammation and irritation of the skin.
- Acne breakout can also occur.
- Furthermore, there are also different concentrations of antihypertensive vasodilator available. It is better to consult a doctor, who can then recommend the most suitable formulation for your needs, as well as to track your treatment progress.
ANOTHER POTENTIAL DRAWBACK TO CONSIDER
These medications need to be used daily — twice daily for the antihypertensive vasodilator, and once daily for the 5α-reductase inhibitor.
Some people may find it difficult to adhere to this regimen over the long term.
