Recover Thickening Hair Loss Conditioner, 16 Fl Oz

Does it have parabens?

Can i still use my argan oil other anti frizz oils after using the actiiv shampoos and conditioner products without fear of effecting the results?

How long does it have to stay in your hair before rinsing?

For the cleaner it says to leave in hair for 5 minutes. How long should this conditioner be left in hair?
