I have the EXACT same thing and use the exact same products - I first shampoo with H&S and then Shampoo & Condition with Redken Smooth Down - Works perfectly, if I don't use the H&S first, dry itchy scalp attacks but I can't go without my Redken, my hair LOVES it! Try using the H&S Shampoo first and then the Redken after, a tiny bit more stuffing around but no itchy scalp AND perfect hair is worth it xx
