Silkier hair
[This review was collected as part of a promotion.] IGK Cash In Instant Repair Hair Serum helps hair to have a soft and silky feel. I thought my hair instantly looked healthier and softer after using. It also has 450 degrees of heat protection which helps protect your hair when styling with hot tools. When using this product my hair felt softer, stronger and looked less damaged. I would definitely recommend this product to family & friends.

Used Once
Unfortunately, the odor of this product is very unpleasant. I put it in my hair once and had to wash it out within the hour because the odor was so strong.

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 Kerastase 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.
