Best Answer: Jill,
I would love to answer tis question for you but I don't know. I use this and do like it very much. I work for an airline and wash my hair with lots of different types of water and the jet and all the chemicals are very drying.
I am truly sorry for your bouts with chemo! I pray you are getting better. Have you tried a really good probiotic? I find doubling this when I fly and coconut oil help a lot too, as I have Hypothyroidism and Hashimoto's disease. Which means I lose a lot of hair.
Sorry I can't be of more help.
