Treating the ‘root’ cause of baldness with a dissolvable microneedle patch

Although some people say that baldness is the 'new sexy,' for those losing their hair, it can be distressing. An array of over-the-counter remedies are available, but most of them don't focus on the primary causes: oxidative stress and insufficient circulation.
