[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.

This doesn’t work at all. Don’t believe all the hype. It did nothing for my hair, smells bad and is overpriced.

[This review was collected as part of a promotion.] I love this product! It smells amazing and my hair looks and feels amazing! A little goes a long ways! I seen results after the first use! I also love the colorful packaging

Great product I live in Florida the humidity is horrible hard to control your hair. This product definately works on the frizziness

OMG you guys, if you are looking for the salon sleek finish and smell then this is for you! I Apply this to damp hair and when its completely dry I go in with my flat iron and omg! I love serums more than spray heat protectants because I have super frizzy low porosity hair. I threw away my chi heat protectant because it left my hair super crunchy.

I've been using this serum for a little over a week now. It sure helps with being on vacation in Georgia and Florida with the frizz!! Already buying the other products. Love!!

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!

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.

WOW, this serum is the best by far. Makes your hair shiny and soft without the frizz. I simply LOVE this product, THE BEST!!!!!!!!!!!!!!!!!!!

[This review was collected as part of a promotion.] This is a great hair serum. I have tried others but really love the @igkhair formula!!! it did not weigh my hair down but I could immediately see results when I used this product#complimentary #IGKHairLove @Influenster @igkhair

This product is AMAZING! I could tell a different in my hair after the first time using this product. The smell is just an added bonus. I highly recommend this product.

Love this so much!!! Smells so so good. Hair felt softer after use. Will be buying more!

I bought one bottle to try. I used it for 3 days and bought 5 more! It’s THAT good. It’s weightless, smells great and makes my super thin frizzy hair feel great!

I liked it but Crybaby is better for smoothing, shine and taming frizz. At least for my hair.

[This review was collected as part of a promotion.] I’ve been using this serum for a while now, and I’ve definitely noticed some differences in my hair. I’ve noticed that it is much softer and hydrated, as well as my split ends are almost all gone!

This product did everything but repair my hair. It dried it out making my hair brittle. Will never buy this product again and i should have known with the over advertising.

[This review was collected as part of a promotion.] Absolutely fell in love with this Instant Repair Hair Serum. It helps my hair look and feel healthy without weighing down my very fine hair. I can use it wet or dry to add smoothness, shine, AND heat protection. And the scent is excellent!

[This review was collected as part of a promotion.] Nice. It is a Quality product, with nice applicator and packaging. Convenient to use. The texture is not greasy and leaves my hair looks and smell good

[This review was collected as part of a promotion.] I have very curly hair and I blow dry my hair once a week to get it pretty straight so I can braid it. This serum has a great amount of slippery feeling so that I can detangle my thick, curly hair and it acted as a nice heat protectant as well. It left my hair quite shiny also. I would recommend if you frequently blow dry your hair and want to prevent damage.

[This review was collected as part of a promotion.] This product absolutely smells amazing , that is the #1 pro for me!! It’s also very lightweight which I also love so the product doesn’t way down my hair. I try keeping my hair as protected as I can, but split ends happen and this repair serum really works well!
