This is an important consideration before choosing to undergo hair transplantation. If you choose to have a hair transplant you need to consider whether you will continue to lose hair in the future. As the hair transplant is permanent you don’t want to be left with an area of transplant hair and no hair elsewhere as this has been lost through the normal hair loss process. Therefore, you must consider 2 things:
- Whether you should be taking treatment to prevent hair loss after your hair transplant
- Whether you can have more hair transplants down the line to fill areas you have lost hair in
Taking finasteride is a good way to prevent future hair loss and regrow any thinning hairs. It helps to preserve your existing hair and your hair transplant so that you don’t require any more transplants in the future.
How does Finasteride work?
In most people suffering hair loss, hair thins and falls out due to a hormone called dihydrotestosterone (DHT). DHT is converted from testosterone in the skin and it works to thin your hair and make it fall out. It most men and women it is the main driver of hair thinning and hair loss. Finasteride prevents the production of DHT meaning that we stop the process of hair loss.
Does Finasteride work?
Studies have shown that by taking 1mg of Finasteride everyday, DHT levels in the scalp reduce by 60%. This means:
- Hair loss is stopped in 86% of males
- 65% of men report a significant increase in hair growth
Side effects of Finasteride
Like any medication there are potential side effects of Finasteride such as low mood and sexual dysfunction (2.1-3.8%), both being rare but common worries amongst those who decide to take Finasteride.
If you don’t want to take Finasteride then you need to talk with your surgeon carefully around whether you can have more hair transplants in the future. This all depends on the amount of hair you have at the back of your head. If you have plenty of hair available then that means you can have further hair transplants should you need them.
