After my husband's brain stem bleed, he was having problems with his scalp. Because of his bleed his skin was left scaly. My hairdresser had Malibu C Scalp Wellness Shampoo in her salon and she recommended it to me. After a couple of shampooings he noticed a big difference in his scalp. So we have continued to use it. My brother-in-law has psoriasis and he is now using it all over his body. we won't ever change.
