    I bought this on advice from the salesperson as an alternative to the Redken 11 Iron Shape (after they changed the formula and added beeswax which made it horrific to use!). I am very happy with...

    Solid stuff. I've tried cheaper products (looking at you, g2b Guardian Angel) and alternative salon brands, and I always either hated that I had to tolerate an awful smell or sticky, tangled hair...

    The Osis Flatliner is a good spray for protecting your hair from heat, without making your hair sticky or greasy. I guess it does help to make your hair more straight, though I am not the best...

    I like the bottle that it comes in. I have been using this spray for a few years now, and I guess it protects my hair. It smells bad, but it doesn't make my hair smell like it, thank goodness. I...

    Oh my.... What was I thinking when I bought Flatliner. It smells awful, like some cheap alcohol, it makes my hair crunchy and dry. I would not buy this product again!!!
