Your confidence is misplaced. From a business point of view they’re making more money now by managing symptoms than if it were possible to completely cure baldness.
While the thesis of your argument is valid (based on US healthcare and their sentiment), your argument is, most likely, flawed.
The premise is that a “cure” is a one time expense, hence why it’s less appealing than managing symptoms. However, in this particular case, I believe the cure will be similar to ED solutions: continued stream of income.
Per the article, the amount of work to replace hair is costly. In addition, it requires follow ups and maintenance. Hence, between the multi-stage process and maintenance procedures, it will be a goldmine.
In the future, a solution for baldness will, most likely, resemble skincare products or vision correction.
