Many people using Minoxidil topical lotion look for shortcuts to faster hair growth. One of the most common ideas: shave the scalp once baby hair appears, so the new hair grows in thicker and faster. Is there any truth to this?
In this article based on his educational video, Dr. John Watts — noted dermatologist, trichologist and one of the best hair transplant surgeons in Hyderabad, with over 2,000 hair transplant surgeries performed — answers a viewer's question on exactly this.
The viewer asked: "Sir, we usually get new hair after using Minoxidil. I want to know if after using Minoxidil is it possible to grow hair faster or do they grow better by shaving my scalp. Will new hair stop growing if one shaves the head or grow normally along with existing hair?"
The short answer: shaving does not help
Dr. Watts clarifies that shaving the scalp will not promote faster hair growth in any way. The belief has no scientific basis.
"The hair that grows as a result of Minoxidil usage is usually weak, and its growth rate is slower compared to normal existing hair. Additionally, they do not grow uniformly along with the existing hair. If the scalp is shaved, Minoxidil-induced hair will take time to grow alongside existing hair, which may grow faster," he informed.
What Minoxidil-induced hair is really like
Dr. Watts lists the key characteristics of Minoxidil-induced hair:
- It is generally weaker than existing hair
- It grows more slowly than existing hair
- It does not grow uniformly with the rest of your hair
- If you stop using Minoxidil, these hairs may disappear
Why shaving can actually backfire
"It's important to understand that shaving the scalp will not lead to better hair growth. Only the side and back hair may grow faster, while the front and centre hair may not show significant growth. On the contrary, shaving the scalp may only expose baldness," Dr. Watts explained.
In other words, after a full shave, the strong zones regrow quickly while the weak Minoxidil-dependent zones lag behind — making thinning look worse, not better.
What to do instead
For those noticing small baby hair growth on Minoxidil, Dr. Watts suggests a better approach: trim the hair rather than shaving the scalp. Shaving will not yield the desired results and may only create a disproportionate appearance, with some areas growing fast and others inadequately.
The bottom line
Shaving your head does not supercharge Minoxidil. Minoxidil-induced hair is weaker, slower and uneven by nature — and a full shave only exposes that. Trim instead of shaving, stay consistent with your prescribed treatment, and consult a specialist if your response to Minoxidil seems poor.
