Natori, I have gotten great results healthy hair which resulted in growth. I think the biggest thing is the type of ingredients. she doesnt use any synthetic oils or anything. I read about the products on another forum and decided to try them I am transitioning from a perm and my biggest thing was experimenting with products to see what works best for me and these are the ones I cant live without. she has a 800 number and she talks to you personally because the first time I called I was impressed how she actually took the time to explain what I needed to do she knows soooooooo much about achieving healthy hair and the system is for all hair types. hope this helps
