During this pandemic, Boostnblend is so amazing!! I can hide my greys and the brush on color stays where I placed it. Also, I use the fibers, and for the first time I feel beautiful again, not ashame of my balding spots on my top of my head. You saved my life!! I tried so many products that would clumps(Topix) or itch (store bought-forgot the brand) so I am quite experience in all these sprays and powders-fibers. I LOVE LOVE Boostnblend!!! Please promise me you will never change your formula, you never have to improve this, it is so perfect no itching or color rubbing off. Thank from the bottom of my heart.
