It is good for frizz control, the effects last for 3 days. Very small amount is needed.
Don’t know about the hair being straight for 3 day but works as a leave in conditioner and does last for a long amount of time and its easy to apply and no greasy texture makes your hair looks shiny and smooth.
Extremely lightweight formula. The smallest amount delivers hydration for a frizz-free smooth finish. I have extremely fine hair and yet this product doesn't make it limp and greasy. I can totally skip the conditioner and only the tiniest amount is required.
Makes hair smooth for 2 days. But holding power is less. Too costly. Should see benefit effects after long-term use.
