Review: Best Buy - I didnt have a lot of faith in this because I have tried so many products and salon treatments but they always left me wanting for more. So when i tried this, i actually did it right before sleep, like an after thought. I was immediately pleasantly surprised by its scent. It smelled rich and sweet. I got a kittle worried as i was blow drying. It didnt seem to have any difference from how it feels blowdrying with my other products. Per product instruction, it is activated by flat irons. And immediately as I started ironing, my hair softened. It straightened quick with just 1 glide. My hair is thin so it didnt take long. It was shiny and flowy and my fingers went through it like cutting butter. But It was late and i had to sleep. I thought it was going to go back to being stringy and dry by the next day (coz thats how my hair usually is after sleep). It is the next day AND it feels and looks soft and shiny still. I am so impressed. I will buy again for sure. Ill update this review after 5 days to see if thats as long as it lasts (as it says on the bottle). Review: MIRACLE IN A BOTTLE - I recently cut my 2c coarse frizzy hair eleven inches. My hair now comes up to my shoulders and looks like a triangle bob when curly. Stupid me thought I could iron it every day. Dumb idea. After a month of ironing/blowdrying my hair every other day (with heat protector), my hair lost ALL its shine and barely holds a straightening. I didn't want to spend $300 on a permanent salon straightening, so I looked into many different options. It came down to an at-home keratin straightening with a full kit or this. I decided to try this, as it didn't seem nearly as harsh as the other one; I was scared an at-home permanent straightening could make my hair fall out. This seemed pretty idiot-proof :) ~EXPECTATIONS: Most of the reviews seemed to suggest that this was the miracle in a bottle I was looking for, but I was a little skeptical. It was only sold on desertcart and the Chi website, and I couldn't find reviews anywhere other than desertcart, which was both a little odd to me. No Youtube reviews or beauty blog posts on this product. I expected: 1) Softer silkier hair - due to the keratin 2) Straightening with flat irons and blowdrys that last longer 3) Heavier hair - also due to the keratin :) Keratin builds up on hair and can weigh it down, so I did buy a clarifying shampoo to go with it. ~HOW IT WORKED FOR ME: Holy cow! This was AMAZING. It did everything I expected, and more. I put it in freshly washed, mostly dry hair, even though instructions say to use it on damp hair. I also used a LOT, putting on each section of hair as I blew it, and my hair didn't feel heavy at all. As soon as I blew it, I noticed a massive difference. Firstly, it was baby soft! It was like different hair. Second, it made blowing my hair ten times quicker, and my hair didn't get as puffy as it normally did. I didn't even need to iron it, but I did, mainly because I wanted it to last at least 3 days (to minimize heat use). The only 'bad' thing about this is that it smells a little like soap, but its very faint. To people wondering if this protects hair from heat, it doesn't. It's a treatment, not a heat protectant - I used a heat spray after blowing/before ironing. This works great in humidity, terrible in rain (duh). The longest I've gone without washing it out was 5 days, and I only needed to touch up the ends once, but beware of oily hair *-* I use this now twice a week, and it works amazing. If your hair starts to feel greasy after a few uses, it's normal! Keratin is a great protein for hair, but too much can weigh down hair, especially fine hair, so make sure to incorporate a clarifying shampoo into your routine. ~PRODUCTS I USE: Shampoo - giovanni tea tree triple treat shampoo (clarifies and removes buildup) // Conditioner - aussie miracles moist 3 minute deep conditioner // Heat Protector - tresemme heat tamer spray // Leave-in Conditioner - garnier fructis curl air dry cream ## Features - Thermally activated smoothing treatment combines with the heat of a styling iron to smooth the hair cuticle, lock in moisture and seal out humidity - Long-lasting results, even after washing - Infused with Keratix, a unique compound that utilizes sustained- release technology to gradually releases proteins, providing long-lasting treatment results - Contains keratin a unique compound that utilizes sustained release technology to gradually release strengthening and smoothing proteins as needed for long lasting treatment results ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00Q8TIMY8 | | Best Sellers Rank | #13,348 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #30 in Hair Styling Serums | | Brand Name | CHI | | Customer Reviews | 4.4 out of 5 stars 7,447 Reviews | | Global Trade Identification Number | 00633911752623 | | Hair Type | Treatments | | Item Form | Liquid | | Item Volume | 3.92 fluid ounces | | Item Weight | 100 g | | Liquid Volume | 115 ml | | Manufacturer | Farouk Systems Inc | | Material Type Free | Paraben Free | | Number of Items | 1 | | Product Benefits | Maintains moisture levels. | | Scent | Tea Tree | | Scent Name | Tea Tree | | UPC | 633911752623 | | Unit Count | 3.92 Fluid Ounces | ## Product Details - **Hair Type:** Treatments - **Liquid Volume:** 115 ml - **Material Type Free:** Paraben Free - **Product Benefits:** Maintains moisture levels. - **Scent:** Tea Tree ## Images ![Keratin K-Trix 5 Smoothing Treatment, Hair Serum, 3.92 Oz - Image 1](https://m.media-amazon.com/images/I/4126iDTdXSL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: I am a little confused with this product. do i only use this once per 5 washes? or every time i wash my hair?** A: You can use this every 5 washes (there website says it’s based on once daily wash). I have pretty dry hair at the ends so I use it every other wash and found it works well that way. I would just watch for build up if you’re using it more often but everyone’s hair is different. Use this with a little dry oil spray or hair serum and your hair will be super soft and shiny. **Q: Can i get my hair dyed after using this? i got this and used it and it worked great! but i have a hair apt. to get dyed in 2 days.** A: If you use this product with a hairdryer or flat iron, then I think you can get it dyed in two days. I wouldn't use it as a leave-in conditioner (without heat) and then get the hair dyed. It's very thick, and may coat the hair too much for the dye to work correctly, if used without the heat of a dryer or flat iron. That's my opinion. **Q: How often we can use use this serum?** A: I use it everytime I wash my hair, it will dampen your hair when you use it so it’s best to use it prior to styling. Smells great and works great! However there is nothing that can stop the frizz during a thunderstorm (happening right now lol) **Q: Will I still have to use a thermal heat protectant spray along with this?** A: I think I would. I feel that this soaks on the top layer. And thermal spray are better for section by section. Like I would use this before blow drying and heat spray before straightening ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Buy *by L***Z on June 18, 2020* I didnt have a lot of faith in this because I have tried so many products and salon treatments but they always left me wanting for more.

I blow dried and flat ironed my hair according to the product directions, and it looked like I had gotten a keratin treatment; my hair was incredibly smooth and soft, and it did a great job of reducing frizz. One star off because the claim of lasting five washes didn't hold true for me (my hair was basically back to normal the next time I washed it), but this is overall a great product for achieving a smooth blowout at home. ## Frequently Bought Together - CHI Keratin K-Trix 5 Smoothing Treatment, Hair Serum For Creating Smooth, Frizz-Free Styles That Last, Sulfate, Paraben, & Cruelty-Free, 3.92 Oz - CHI 44 Iron Guard Thermal Protection Spray, Nourishing Formula Helps Resist Heat Damage to Hair & Tame Frizz, 2 Oz - CHI Keratin Leave-in Conditioner, Hydrating Conditioner For Restoring Softness & Preventing Breakage, Great For Daily Use, Sulfate-free, 6 Oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/58077779-keratin-k-trix-5-smoothing-treatment-hair-serum-3-92](https://www.desertcart.tn/products/58077779-keratin-k-trix-5-smoothing-treatment-hair-serum-3-92) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-21*
