What is MBL hair? To be honest, I dont notice anything being drying to my hair, other than using a hair dryer, the hand held kind. I do like the Deva foam, but it does not have enough hold for my hair, at least not in this weather. It is good, but I have not found it to be so much superior to other mousses I like. I dont mind the price too much because I use less. I guess there are tradeoffs.
