I had many compliments.. **Q: can this be applied on top of other keratin treatments? I last did my daughters hair 4 months ago with Kerasilk keratin treatment.** A: I'm a not a professional hair dresser by any means. I just like saving money. I had previously done my hair at a salon and they used a different treatment. I could tell because it smelled different and it was very flaky when they dried it. I used Complex Brazilian Global and my hair turned out gorgeous. You just have to make sure you blow dry it VERY straight, like they do in the salon and also seal it with the hair straightener. Good luck! **Q: Can I put my hair up within the three days I leave it in?** A: You shouldn't because it will leave the lines in your hair. Try to keep it as straight as possible I straightened my hair everyday to keep it perfect. ## Frequently Bought Together - Keratin Research Complex Brazilian Keratin Hair Argan Oil Blowout Treatment Professional Results Straightening and Smoothing Hair Queratina Keratina - Straightening Easy Comb High Heat resistant for Brazilian Keratin Hair Treatment and Straightening Spring Action for Speedy flat ironing - Herstyler Hair Straightening Comb - Flat Iron Comb - Hair Straightener Comb With a Firm Grip - Styling Comb for Women (Pink) --- ## 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.sn/products/1972194-keratin-research-large-set-brazilian-keratin-hair-straightening-complex-long](https://www.desertcart.sn/products/1972194-keratin-research-large-set-brazilian-keratin-hair-straightening-complex-long) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-13*
