Elnett heat protection/ BAD!!!

I recently bought this cause the saleswoman said this is wonderful and that she uses it by herself.
At first I really like the packing it's a bottle in a bottle and it has a lock.
So it makes my hair less dry but I don't think it makes my hair straigher than normally.
It's very sticky but when you straight it it'll come out well.
Yeah if ytou used this please tell me what you think <3
