I suffer with terrible scalp issues, dryness, scabbing, flaking, cracking and bleeding. some nights struggling to sleep from it, I use this when it starts to flare up and honestly it’s been a game changer. It’s got a very strong smell and does tingle so may not be suitable for everyone but doesn’t leave my hair dry like other dandruff shampoos etc. so far this is the only thing that’s worked for me.
