Minoxidil for hair loss: what are the drawbacks?
HLN, 19 October 2022
Dr Griet Voet and Dr Joren Brassine in HLN on minoxidil: how it slows hair loss and which side effects you can expect.
HLN looked into how well minoxidil works against hair loss and what its downsides are. Dermatologist Dr Griet Voet and aesthetic physician Dr Joren Brassine explain that minoxidil prolongs the growth phase of the hair and can make hair thicker and denser, although the exact mechanism is not yet fully understood. The result varies greatly from person to person.
The doctors point to possible side effects of the lotion, such as itching and irritation, and sometimes extra fine hair on the face. A foam version is often less irritating. The tablet form has more serious potential side effects, which is why doctors usually prescribe the lotion first.
The medication is mainly used for hereditary or hormonal hair loss. A full head of hair is never guaranteed; seeking medical advice beforehand remains advisable.
Key advice
Minoxidil does not work equally well for everyone; do not expect a guarantee.
Itching or irritation from the lotion? A foam version is often better tolerated.
Ask a doctor for advice before you start, especially for the tablet form.
“Its effect varies from patient to patient.” — Dr Griet Voet and Dr Joren Brassine
