The best thing for your hair.

This is seriously the best product I have ever used on my hair. And that says a lot, because I only use good, good stuff - from Kérastase to Oribe. What I mean is that Cash In is better than any other super expensive product out there. If you have frizzy, coarse hair look no further. This serum is pure magic and makes hair manageable and super soft, shiny and moisturized. I will never be without it again!

IGK

Every single one of IGK items is absolutely the best. As someone who has tried every product (high end) out there, I give it a 10 for sure. It has made a huge difference in the time it takes to do my hair. No more fussing to get it right. A good hair cut and these products is all you need.
