How is it different from regular hairspray?

Regular hairspray was never made to hold fibers.

This one was. Spray it over your fibers and it locks them in place. Water resistant, scalp friendly, and it holds 24H+.

  • Locks fibers in. Your coverage stays where you put it.

  • 24H+ hold. Style it once.

  • Water resistant. Built to hold up.

  • Scalp friendly. Made to spray over your hair and scalp.

Fibers cover, this keeps them there. That's literally it. I spray it on after and don't think about my hair for the rest of the day, through uni, the gym and dinner at my parents'

caught in the rain, still there

Got caught in the rain walking from the station to work, full panic mode. Checked the mirror in the office toilets and everything was still in place. Water resistant isn't just on the bottle for show

doesn't move the fibers

Spray from about 20cm like it says and it doesn't push a single fiber around, it just locks them. My crown looks exactly how I left it in the mirror, hours later

normal hairspray isn't the same

Before this I put regular hairspray on my fibers and it clumped them into little black bits. This one is actually made for fibers and you can tell, the coverage stays even and looks like hair
