Hey Ladies have you ever heard of or used Ouidan( pronounced Wee-don) hair products?

I have a pamphlet that explains that this line of products is specifically for curly hair of all types, however i dont know many women that have used it, the only one that i know of who has used it is a friend of one of my friends.She told me that it was good, but I'm not sure if it will work for me. Mine is very thick and tightly curled ethnic hair, my scalp is also sensitive. So have you ever used this product or heard of anyone that has, if so can you tell if it is worth purchasing. Thank you for your answers.
