I have dry scalp. my head gets extremely itchy but only at night time. can you suggest a good shampoo?

Dry/Itchy Scalp: Are you showering at night and using something at night? Hair sprays, gels, perfumes, etc.. can all have drying effects on the scalp and make it worse. You need a hydrating/moisturizing shampoo that is fragrance-free and dye-free. You might even want to consider using Moroccan Oil every other shower. Too many products and you need to find which works best for you.
