Tidying up the sparse hairline

As I get older, the gaps in my hairline are becoming visible, so at first I used to apply just a little bit of black or brown eyeshadow. But then I tried a product my mother bought for me at Costco, and it was so good that I use it often now.

Are there any similar products from other brands?

I use it to tidy up my hairline according to the direction of my parting, and sometimes when I wear a ponytail or an updo, I find that lightly patting it with something like this makes it look neat and tidy.

I think I'll finish using the Reen Perfect Cover Hair Cushion by the end of this year, so I should look up products from other brands as well.
