I bought this set to try out the products and see if I liked them. The sizes are pretty decent, you do get enough product to try them out and figure if they work or not for you, I put them to the test by trying them on different days to see the difference in my hair from each product . My favorite product is the Intense Hydrating Mask, I was able to notice a difference in my hair it totally moisturize my hair making it healthier , silky and smooth. I also enjoyed using the Huile Soyeuse Lightweight Hydrating oil, I think that it is a good product it definitely does the job by making my hair shinny but not oily, removing the frizz and it is lightweight. Lastly it comes with a Shampoo as well (Intense Hydration Brilliance Shampoo) Which I kind of didn't enjoyed as much as the other two products, the consistency is too thin and watery and I didn't like that, I don't feel it does as much due to that, i would prefer if it was thicker and not as watery. Overall I feel it was worth it purchasing this travel kit to try the products and I'm glad I found two products I really like and will continue to use.
