Yeah, I still hair, but it's definitely a bit thin up top. I sure wouldn't mind having the same head of hair I had when I was 17. But more importantly, if this can help cancer patients who lost their hair due to their treatments then it's even more important.
A wearable device for regrowing hair. Although some people embrace the saying 'bald is beautiful,' for others, alopecia, or excessive hair loss, can cause stress and anxiety.

I know a lot of guys are vain about their hair loss but not me. Yeah my hairline has receded some but so what. I still have a nice head of hair and still look great for my age. I will not use something to regrow my hair but for some I know it is a big deal to them.
