Dry hair needs a lot of care and attention below is a brief discription on how to maintain it best

DRY HAIR  Dry, coarse and brittle hair needs to be nourished from within; a conditioner that just rinses out won't do the job. Use an intensive moisturising shampoo which will cleanse without excessive rubbing (which will damage the hair more) and follow with a hot oil conditioner. Heat opens up the hair cuticles allowing the moisturiser to penetrate the hair shaft giving it suppleness, bounce and movement. Mousse on dry hair will make it look dull, use a blow drying or thickening lotion instead.
