Hi, love, thx for shopping with her hair company and leave your comments here for quality approvement, since our hair is all chemical free, we don't use any chemical to do curl, only hot steam will be applied to do the texture. That's why our curl can't hold permanently like the chemical applied curly hair. Normally the curl should be able to hold for 1 month or so with proper maintenance, if your curl holding time is less than it, please reach out to our service team with email shown on website(sorry I can't write down the email address here due to limitation from shop app), and we will help you out to find out the problem and fix it for sure.
