Viewers of Dr. John Watts' YouTube channel keep sending in questions about hair transplants, hair loss and hair growth. In this article based on his educational Q&A video, Dr. John Watts — dermatologist, trichologist and hair transplant surgeon in Hyderabad — answers six of them, including one persistent myth.
Does masturbation cause hair fall?
Let's settle the headline question first. Rohan asked whether masturbation can lead to hair fall. Dr. Watts' answer is unambiguous: no — masturbation or sex has no link with hair fall.
Is a vertex (crown) transplant worth it?
Dinesh Reddy was told that vertex baldness transplants are not effective. Dr. Watts explains that hair transplants give their best results when donor grafts from the back of the scalp or beard are placed on the front of the scalp. On the vertex or mid-scalp crown, results usually get reduced by 15-20%.
"You cannot expect full density here even after a transplant. You can only get a virtual density on the vertex," informs Dr. Watts.
Can Minoxidil plus Finasteride regrow early-stage hair loss?
CV Lee, in the early stages of hair loss, asked about 2% Minoxidil with Finasteride. Dr. Watts says those in the early stage of androgenetic alopecia will see very good results even with plain Minoxidil, and topical Minoxidil with Finasteride also provides good results.
The critical rule: never stop these drugs abruptly once prescribed. If treatment is disrupted suddenly, the regained hair — including baby hair growth — is lost again. Continuing the medication may even prevent any future need for a hair transplant.
Can Minoxidil cause chest pain?
Sethupathi Vamsi reported light chest pain after three days of Minoxidil. Dr. Watts explains that Minoxidil is a vasodilator — it opens up or slightly widens blood vessels so more blood is supplied. As a consequence, blood pressure can drop slightly in some people, and in rare cases it can cause palpitations.
"But chest pain I have never come across as a side effect," he said, advising the viewer to consult a physician, since chest pain could also be linked to gastric issues.
Can Minoxidil grow back the hairline?
Sai Akhil asked if Minoxidil can regrow the hairline. The best Minoxidil results appear on the crown, where baby hair grows, darkens and gains some density. On the hairline, baby hair can grow and cover a shiny balding spot — "But you cannot expect full-length hair on the hairline that you can style," says Dr. Watts. Even this baby hair disappears if you stop abruptly; once started, continue for at least 5-6 years.
How often should you use a dermaroller?
Ram N had used a dermaroller daily for three months — with injuries and bleeding, but no results. Dr. Watts is clear: dermarolling is good, but never daily. "It is better if one uses it once in 10 days or 20 days and not every day," he advises. The dermaroller works through an inflammatory healing technique, and overuse causes multiple injuries that can lead to fibrosis and damage existing hair. Never roll again before the previous injury has healed.
The bottom line
Masturbation doesn't cause hair loss — that myth can rest. The real lessons here: vertex transplants give reduced density, Minoxidil and Finasteride work best when used consistently and never stopped abruptly, and tools like dermarollers help only when used sparingly under guidance.

Frequently asked questions
Does masturbation cause hair loss?
No. According to Dr. Watts, masturbation or sex has no link with hair fall.
Are hair transplants on the crown (vertex) effective?
Results on the vertex are usually reduced by 15-20% compared to the front of the scalp. You get virtual density rather than full density.
Can Minoxidil cause chest pain?
Minoxidil is a vasodilator that can slightly lower BP and rarely cause palpitations, but Dr. Watts has never come across chest pain as a side effect. Chest pain could be gastric — consult a physician.
How often should I use a dermaroller?
Once every 10-20 days, not daily, and only after consulting a dermatologist. Daily use causes injuries that can lead to fibrosis and damage existing hair.
