UNITE Hair - U Oil - Multi-Tasking Argan Oil for Hydration, Shine, and Frizz Control - Ideal for All Hair Types and Textures, 4 Fl Oz

This product is sold for half the cost; is it the real thing?

How do you this with Unite 7 Seconds Detangler?

I use unite boing curl leave in spray & unite boing curl defining cream. at one point would i use the argan oil? before or after the other products?

Can this be used with white hair?
