Three of the most practical questions Dr. John Watts — dermatologist, trichologist and hair transplant surgeon in Hyderabad — receives from patients relate to the consequences of missing Minoxidil doses, how long to wear a cap after a hair transplant, and whether yoga can help DHT-related baldness.
What happens if you skip Minoxidil for several days?
“Even if one skips using it for 7–10 days at a stretch, the results would be drastically reduced,” warned Dr. John Watts. The medication needs to be applied regularly to maintain its effect on hair follicle health and blood circulation to the scalp.
How long should you wear a cap after a hair transplant?
“We generally ask the patient to wear a protective cap for 5–10 days after the transplant procedure. You can extend it to one month, or if you like, you can wear a cap whenever you are travelling to a dusty place as a precaution,” clarified Dr. Watts. The cap protects the new grafts from dust, UV exposure and accidental knocks during the crucial early period.
Can yoga (Shirshasana) reverse DHT-related baldness?
“There won’t be any hair growth in DHT-influenced bald regions of the scalp as it cannot act as a DHT blocker,” he explained. For follicles miniaturised by DHT, improved blood flow is not enough — a DHT-blocking medication or a hair transplant is required.
Is it safe to get two hair transplants within two months?
“The ideal time to go for a second hair transplant procedure is after a wait of six months minimum, and not before that,” Dr. Watts stated clearly. The full growth from the first procedure takes 9–12 months. Without allowing for this, the surgeon cannot accurately identify where the first grafts were placed, making it impossible to plan the second procedure correctly.

Frequently asked questions
How many days can I skip Minoxidil without losing results?
Dr. John Watts warns that even skipping 7–10 days at a stretch can drastically reduce results. Consistent daily use is essential for Minoxidil to work effectively.
How long do I need to wear a cap after a hair transplant?
Dr. Watts recommends wearing a protective cap for 5–10 days post-transplant, extendable to one month. Beyond that, wearing a cap in dusty environments is a good optional precaution.
Can I get a second hair transplant after two months?
No. Dr. Watts advises waiting at least six months before a second procedure. The first transplant takes 9–12 months to fully grow, making early second procedures potentially counterproductive.
