Hi guys, newbie here. I just had the Keratin Smoothing System done on my hair last week and I love the results. However, after my first wash (I used approved shampoo and conditioner), I noticed some frizz. I know my hair won't remain as straight as it was the first day, and I'm fine with that....I just don't want to keep seeing an increase in frizzies!

I flat iron my hair daily and that has been working well for the most part, but does anyone know if there are any smoothing/straightening products approved for keratin treated hair? TIA!
