Dear Amanchawla Thank you for posting this question. This is a very important issue in the field of hair restoration surgery. The problem with transplanting a young person, such as a 22 year old man, is that we don't have a solid idea of how much hair loss is going to occur over the next several decades. As the saying in our field goes, "the good thing about hair transplant results is that they are permanent....the bad thing about hair transplant results is that they are permanent." If, despite efforts to slow the hair loss, you progress to a Class 6 or 7 within the next 20 years, the original work done will still be along your hairline. As this is not a pattern of hair loss typically found in nature, it is an unusual appearance that can be socially crippling later in life. Therefore, approaching a frontal hairline reconstruction in a younger person should always be approached with caution and prudence. You might be thinking to yourself, “I won’t care about my hair when I’m 50!”....but let me strongly assure you that you most definitely weill care about your hair when you’re 50. As you age you always feel “young” inside, but your face and body age...you won’t enjoy the aging process no matter how old or young you are. So please don’t think that you can just have whatever hairline you want today and not worry about it when you’re 50 if it looks unnatural, because you most certainly will be concerned with unnatural hair patterns no matter how old you are. Fortunately, recent advances in technology have expanded the ways and effectiveness of preventing hair loss. Finasteride (eg: Propecia) has been around since about 1998 for hair loss. More recently, the science of low-level laser therapy (eg: LLLT) has advanced such that a majority of those who use a high-quality LLLT device can expect the progression of their hair loss to dramatically slow down or appear to stop altogether. In younger people, especially those under 25, there is a decent chance that some of the miniaturized follicles will become thicker and return to terminal (eg: thick, non-thinning hair). Other therapies that have shown promise include platelet rich plasma (eg: PRP), and placental stem cell therapies are also being studied as ways to control the progression of hair loss. Personally, I require men under 24 to undergo at least 8 months of preventive therapy to see if the progression of the hair loss can be controlled with LLLT or PRP. I hope this information is helpful to you. Kind Regards, Ken Anderson, MD, FISHRS
