To be fair, I have only used the shampoo and conditioner bars a few times. I can already see a feel a difference. My hair has become a bit thin on top and I’m now having to deal with it frizzing terribly. Since using these bars, I have had no frizzing and my hair feels thicker. Now I know that it hasn’t miraculously thickened but it looks and feels that way. I’m hoping that with regular use, my hair will start growing again where there are thin patches, but time will tell. I am really happy with these bars and will continue to buy them. Don’t expect lather because there isn’t any, but my hair feels cleaner than when I’ve used regular shampoo. Love it!
