1. I use JessiCurl Deep Conditioner, Shea Moisture also has deep conditioners, I use their Manuka Honey & Yogurt Power Protein Treatment in a DIY protein mask.
2. I use VO5 kiwi shampoo (has sulfate) because I get buildup, but I only use it 1-2 times a month. I useJessiCurl Gentle Lather Shampoo and Kinky-Curly Come Clean Shampoo (both have no sulfates) on my other wash days.
3. Suave Essentials has a good and cheap conditioner I will use to detangle my hair in the shower. I also squish to condish my hair.
4. I also use leave-in conditioners and gels to keep my hair defined and less frizzy, I sometimes use a curl cream.
