I have been struggling with an itchy, dry scalp lately (not too sure why...) but I used this in my parting and the back of my head (where it gets really dry and itchy), I love that you only need to leave this on for 10 minutes. Since washing my hair from the 1st time I had tried this, my scalp feels healthy, with no signs of any itchiness as of yet. Would recommend it as it is a great price point for an AHA scalp serum.
