I have been using Dandruff Scalp Therapy Shampoo for over 10 years and it is fantastic. Not only does it clear any dry flaky scalp but really importantly the shampoo stops itchy and sensitivity immediately & between washes. The shampoo itself is a lovely light consistency and smells clean & fresh but is not overly fragranced. My hair which is prone to dryness & a bit of frizz is sleek and shiny. I love this product. I decant it and take it with me whenever I travel and always keep a stock in the cupboard… even my husband uses it now. I cannot recommend this shampoo enough. It absolutely does what you need it to do.
