Before purchasing, please take a look at my video review of some of the hair products you are going to be buying for your hair. This is not a scientific review. I have tried many products, and I am just as impressed by some of them as others. For your sake, please keep this review unbiased. After reviewing the products I selected, I made a few assumptions: 1) I would be able to use all of them without experiencing any negative side effects. 2) The products I chose would have good ingredients, and 3) I would not experience any irritation when using them. I have tried each product in every way possible: 1) Use the full amount (at least 6 ounces or 1/2 cup for all products) and leave it out for at least 15 minutes 2) Use the product in the morning before you go to work (not just before your hair is dry) 3) When using these products, let them dry naturally, so you don't feel any irritation while using them - it is very important to do so. The results of my hair is pretty much as expected. I love how my hair looks after using the products. After two months of using them, I still have beautiful, full, hair.
