After trying a plethora of shampoos for my itchy flakey scalp, this is the ONLYone that seems to be working well. Although it is on the pricier side ($26 at sephora), I was able to snag it during a 15% sale. Also, my hair is thinking due to my hair follicles becoming blocked so to me the price is worth it if works. And it does! Just after two weeks, I no longer have itchy flakey scalp. I use this together with other products from the same brand such as a scalp elixer, and the phytocayne scalp serum for my thinning hair. Another bonus is that this doesn't dry out my hair like other shampoos targeted for problematic scalp. I highly recommend this product!!
