I've been using this shampoo plus the conditioner from the same series for a while now, but my scalp gets very oily very quickly from the series. I used to wash my hair about once a week, which was best for my hair, but I've had to increase to two to three times because it looks generally rough very quickly. Also, I find that the ends unfortunately get drier, which absolutely doesn't match my hair quality (uncolored, thin strands but very much/thick hair, it then gets very frizzy).
I previously used the Heal series from Maria Nila & that series was much better for my hair, considering switching back 🙂
