It’s possible to conceal early signs of balding by using a concealer or bald spot spray. This is a temporary fix and might come in handy if you’ve just started shedding. They don’t get to the root of the problem. A good bald spot spray typically contains nanofibers and dyes.
So, when you apply it on the affected spots, it entwines with your existing hair provide coverage to areas where it’s needed most. These nanofibers are made from keratin which is the exact same natural material for real hair.
Again, this is a good short-term measure if you have just a few bald spots. It might not work if you’re completely bald though. The sprays typically last for a day or two and you’ll need to re-spray if you need to.
