A viewer, Hari Krishna, asked Dr. John Watts: "I lost 50% of my hair on the scalp. There is exposure of bald skin now due to hair thinning. Should I opt for PRP or a hair transplant procedure in this scenario?"
In this article based on his educational video, Dr. John Watts — dermatologist, trichologist and hair transplant surgeon in Hyderabad — explains the best way forward when half your scalp hair is gone.
Protect what you have first
For those dealing with genetic baldness, a hair transplant provides the best solution if there is sufficient donor hair. But with 50% of hair still on the scalp, Dr. Watts emphasizes that the primary focus should be on protecting the existing hair from falling out with suitable hair medication.
He notes that there is a high likelihood of the scalp appearing bald once you cross the 30% hair thinning threshold — which is why acting early matters.
Get the cause diagnosed before treating
It is essential to diagnose the exact cause of hair loss. Whether it is genetic baldness or caused by other factors should be confirmed before initiating any treatment. Typically, a dermatologist may prescribe Minoxidil and biotin supplements to protect existing hair.
PRP for density, transplant for permanence
If you need to add volume or density, PRP treatment or stem cell therapy may be recommended. Dr. Watts told the viewer that even with 50% existing hair, one can still achieve a decent appearance if the remaining hair is protected.
However, if you are not satisfied and desire a permanent hair solution or a new hairline, then a hair transplant procedure may be necessary. Conversely, if you are content with your current appearance after protecting your hair, a transplant may not be required at all.
The bottom line
With 50% hair loss, the sequence matters: first protect the existing hair with dermatologist-prescribed medication like Minoxidil and biotin, after confirming the cause. Then choose based on your goals — PRP or stem cell therapy to add density to what you have, or a hair transplant if you want a permanent solution and a new hairline. A consultation will tell you which path fits your scalp and expectations.
