A common belief circulates online: shaving your head before applying minoxidil makes the medication work better and grow hair faster. But is it true? In this article based on his educational video, Dr. John Watts — hair transplant surgeon and trichologist in Hyderabad — addresses this question directly.
The question: does shaving help minoxidil work better?
A viewer named Balashankar asked whether shaving the scalp before applying topical minoxidil lotion would improve hair growth results.
Dr. Watts’ answer was clear: shaving is not necessary, and believing it makes a difference is a myth. “He can shave his scalp if he wishes, but it is not likely to affect the hair growth results. If one thinks so, then it is just a myth,” he explained.
The hair growth effect of minoxidil works at the follicle level — inside the scalp — not at the surface. Whether hair is present or absent above the skin does not change how the medication penetrates and acts on the roots.
Why some people prefer shaving anyway
Dr. Watts acknowledges that some users find it easier to apply minoxidil on a shaved scalp. Many find that alcohol-based topical lotions make the hair messy when applied on hair rather than directly on the roots. Shaving eliminates that practical inconvenience — but does not change the outcome.
How to actually track if minoxidil is working
Rather than shaving to assess results, Dr. Watts suggests a practical tracking method: take photographs of the scalp every 20 days from the date you begin minoxidil, for a period of six months. “By comparing the pictures taken over six months, they can easily notice any changes,” he explained.
The key reminder: prescription before use
Dr. Watts ends with a consistent caution: do not use minoxidil topical lotion without a proper prescription from a qualified dermatologist. Dosage, concentration and application method all need to be matched to the individual.
