I'm a big believer in regular trips to the hairdresser (I go every 5-6 weeks for a colour, cut/trim and style) and decent products.

I have Cloud 9 straighteners, I use Sebastian Professional shampoo & conditioner and Moroccan Oil. I also only wash my hair twice a week. My hairdresser actually showed off my hair to the rest of his team just the other week because it's so healthy and shiny!

HTH.
