Hi! I’m an MS MBA student at Harvard Business School with a background in data science, and I’m worried about my hair. I’ve been trying to use an app or website to track my own hair density for losing or gaining hair. I’ve been in this subreddit before but want to be more involved. Would you all be able to tell me what you would want from a tool like this, if you would want it at all?
I have wanted to use an app or website but most of them cost money or don’t work. Even the ones that charge, I see reviews on the App Store that they don’t work.
For a class project I made a physical prototype and software to track hair density and it worked pretty well. (Much better than I expected) I want to develop out the software for my use but also to help others because hardware is harder to share.
I figured for people using hair treatment medicine like minoxidil (like me) it would give a more quantitative way to measure or at least more confidence to continue through the dread shed period, and for people who are starting to lose hair, it would be useful for them to check when to start using treatment. For hair transplants, it would also be useful to track regrowth.
If I did charge people, it would be cheap and mainly to cover cloud charges and ML models that are running segmentation. I’m not looking to make money off a product that I just want to use myself and share.
Any help or information on what would be helpful for you would be really appreciated!
