NEXXUS! Surprisingly enough, once I told my mom about it she informed me that she used it back in the 80's, not only that, but they had a relaxer and she used that too!
KENRA. It's not really a "staple", but I alternate the Color Maintenance Conditioner every few weeks.
ELASTA QP. I use their Leave-In, because it's basically the same as Kenra Daily Provision.
STA SOF FRO. How I hadnt heard of this..? My mom told me she used it when she had a fro back in the 70s. Now I use that when I stretch my relaxers & when I have braids.
