With the ongoing advent of hair transplantation, the biggest question is about it’s longevity. People often ask what is the guarantee that these hair will not defy them.
Let’s binge on some basics…
- Simple understanding of DHT and how it effects the hair….
In a broader sense, the hair follicles at the top of our head is sensitive to the presence of DHT, hence thin out with time and are lost. The ones at the back of our head are ‘relatively insensitive’ hence stay stronger.
- Workings of Hair Transplantation….
The hair roots at the back are extracted to be implanted into the area of balding. With proper graft management density and coverage is achieved and you can find yourself young and confident again.
So far so good right.. but!
This is not it. The transplanted hair is also prone to thinning as time progresses. This owes to two things mainly; our old friend DHT( frenemy rather!) and age.
The theory of Relative(ity) insensitivity…
DHT which is continuously produced in our body, keeps on thinning the hair . FDA approved DHT blocker Finasteride helps them keep strong and healthy. This is same for both non transplanted and transplanted hair, as the ones at the back where only relatively insensitive to DHT remember!!.
The Age factor…
Even though with many patients the transplanted hair looks strong and voluminous after years of an HT procedure, it doesn’t hold true for all. Thinning can occur in transplanted hair as well.
How ‘young’ is really young for HT…
Less than 35years is ideally considered young for HT. But one would not wait till then for a head full of hair. Since the extent of thinning is not complete at that stage, the expertise of a doctor to carefully extract only the true permanent hair roots is imperial here. Which looks strong now, need not be strong later.
Is ‘old’ really old enough..
A forty plus man’s donor will also thin as age progresses. Imagine a 70 year old gentleman with nothing much at the top of his head but decent growth at the back. His donor though good and still extractable is not essentially as good as how it was in his forties! Simply put if the donor hair can thin out at the back, so will the transplanted hair since it is coming from the same place!
That is why it is always safe to assume that after a few years the hair will definitely decrease in volume due to thinning of individual hair but one will not become completely bald again.
