Why are you against a hair transplant for someone 19?

What concerns me is the potential for change and any lack of planning for an outcome like this: https://baldingblog.com/need-master-plan-think-hair-transplants-photos/

I see such patients at all ages who developed balding that they didn’t expect. I always keep my eye on the donor supply, knowing that one should never use it up before the balding pattern completes, which may take many years. Young men in the early 20s don’t worry about getting older (like 30-50), but I see many 50 year old men who had hair transplants years before, and used up their donor supply yet continued to bald.  Fortunately with tests like the HAIRCHECK test, I can often predict the long-term balding pattern when a man reaches 25 (not always) but I can always predict what their donor supply can provide for them for their lifetime.  There are many things today that we couldn’t do years ago like Scalp Micropigmentation which can substitute for hair in certain circumstances (see: https://newhair.com/wp-content/uploads/2018/11/Combining_Follicular_Unit_Extraction_and_Scalp.98621.pdf). For these reasons, I focus on a Strategic Personalized Master Plan for each of my patients because even if they don’t worry about progressive balding, I am planning for it on their behalf.
