i worked with dr.lawrence wilson before,he puts you on supplements based on your hair analysis reading,all i can tell you is,it wasn't working for me.The copper dump that he was saying that i was going thru was just so so bad that i could'nt leave my house and even after stopping the program i was never the same anymore,horrible.And he also did tell me that when starting his program that you can feel bad before feeling better,but i was on it for 2 years isn't that not enough time to see at least some improvment.Also my 3 year old daughter was on it because she had a lot of digestive problems and i was told that she was in adrenal burnout,apparently kids have the same imbalances as there mom,even my daughter hasn't gotten better.And i did test every 4 months,very expensive,plus all these supplements.I guess it work for everyone different,it didn't work for me or my daughter after 2 years on it.
