Review: Really protects against humidity - This product really works! I like it so much I have it shipped to Australis where I now live, even though the shipping costs are high. As a mixed race woman I had difficulty finding products ro smooth my hair in subtropical Brisbane and and decided to see if any of the products I used in the states were available to be shipped to Australia. Voila! Ion's serum could be shipped. I ordered several bottles and could not be happier with the results for my hair. As Brisbane becomes more multiracial, I hope this serum becomes available here. It works! ## Features - Leaves hair silky and healthy looking - Prevents damage from heat styling - Humidity resistant formula - Paraben free - 100% Vegan ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N6HOE6M | | Best Sellers Rank | #254,200 in Beauty ( See Top 100 in Beauty ) #1,051 in Hair Styling Serums | | Brand Name | ION | | Customer Reviews | 4.4 out of 5 stars 246 Reviews | | Hair Type | Frizzy | | Hair type | Frizzy | | Item Form | Serum | | Item Volume | 3.5 Fluid Ounces | | Item form | Serum | | Liquid Volume | 3.5 Fluid Ounces | | Liquid volume | 3.5 Fluid Ounces | | Manufacturer | Arcadia Beauty Labs LLC | | Material Type Free | paraben_free, Oil Free Paraben Free Oil free Paraben Free | | Material type free | paraben_free, Oil Free Paraben Free Oil free Paraben Free | | Number of Items | 1 | | Product Benefits | Shine | | Product benefits | Shine | | Scent | Unscented | | Scent Name | Unscented | | Unit Count | 1.00 Count | ## Product Details - **Hair type:** Frizzy - **Liquid volume:** 3.5 Fluid Ounces - **Material type free:** paraben_free, Oil Free Paraben Free Oil free Paraben Free - **Product benefits:** Shine - **Scent:** Unscented ## Images ![Ion Humidity Defying Serum, Paraben-Free, Vegan, Anti-Frizz, Smoothing, Oil-Free, Thermal Heat Protectant - Image 1](https://m.media-amazon.com/images/I/51tACAKf3CL.jpg) ![Ion Humidity Defying Serum, Paraben-Free, Vegan, Anti-Frizz, Smoothing, Oil-Free, Thermal Heat Protectant - Image 2](https://m.media-amazon.com/images/I/51NCYhY7fiL.jpg) ![Ion Humidity Defying Serum, Paraben-Free, Vegan, Anti-Frizz, Smoothing, Oil-Free, Thermal Heat Protectant - Image 3](https://m.media-amazon.com/images/I/617fcoR4V1L.jpg) ![Ion Humidity Defying Serum, Paraben-Free, Vegan, Anti-Frizz, Smoothing, Oil-Free, Thermal Heat Protectant - Image 4](https://m.media-amazon.com/images/I/81olOvSjEbL.jpg) ![Ion Humidity Defying Serum, Paraben-Free, Vegan, Anti-Frizz, Smoothing, Oil-Free, Thermal Heat Protectant - Image 5](https://m.media-amazon.com/images/I/61R-nCi6VIL.jpg) ## Questions & Answers **Q: Is this a spray on product ?** A: No, it' s serum for Humidity Resistant, Oil Control, Shine Thanks! **Q: Is it safe for color treated hair?** A: Yes it is safe for color treated hair. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by D***A on 15 October 2022* You only need a tiny dab of this, rub into your hands and then apply to wet hair.
