    Funny smell

    This has a funny smell and I’m sorry I can’t get past that because it seems like it would be a nice product otherwise.

Got questions? Don’t worry, we have the answers

Can I use S1 Ultimate Styling Serum on hair extensions?

Yes! The styling range can be used on human hair extensions, wigs and weaves. We don't advise using it on synthetic hair pieces.
