I can vouch for the "It's a Ten" spray mist and the tub of deep conditioning mask. It's almost too rich for my fine curly hair, so I tend to use it once a month, maybe more during summer months. The product comes in signature cobalt blue bottle/tubs, with a white label (trimmed in hot pink).
My favorite hair product to use lately I is made by Matrix: Biolaģe Exquisite Hair Oil. I use all three of them in random, alternate ways. Strengthening (pink) - about once a week. Protective (amber) - almost daily. Softening (Tortoise) - whenever I want my hair to be gorgeous --- whenever I use this oil in particular, I seem to get lots of compliments on the way my hair 'behaves'.
When I straighten my hair with a ceramic flat iron, I use the pink oil before I apply the iron. After I am completely finished ironing my hair straight (or with a big barrel iron), I follow through with a touch of the amber oil. After my hair has cooled off completely, it's one more touch of the Tortoise (softening) oil.
I don't straighten my hair often, but when I do, it's because I like to put it up in a loosely styled French twist.
