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 ## 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.us/products/58077779-chi-keratin-k-trix-5-smoothing-treatment-hair-serum-3](https://www.desertcart.us/products/58077779-chi-keratin-k-trix-5-smoothing-treatment-hair-serum-3) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-13*
