I used concealer for nearly 2 years. It did the job, but I always looked at it as a non-permanent solution while I was working up the courage to get a piece! I bought me some time as I came off the regaine and did my hair system research online. At least it's cheap

But yeah, getting caught in a rain shower is a disaster. There will be weird black drops all along your hairline. Also, don't let a girl put her hands in your hair as they will come back all dirty looking heheh.

I should also add that concealer is a LOT more detectable than a hair system. When I had concealer, lots of people were looking at my hairline strangely when up close (looks like there is dirt in there, and on your scalp), but now nobody ever looks at it.
