PAUL MITCHELL - extra body daily shampoo thickens fine and normal hair. Using this helped my baby fine hair hold my hair color & not frizz in humidity (whether in New England or Florida! You can't beat Paul Mitchell products for quality & results. I've been using this for at least 15 years now. I sometime switch off to their Tea Tree Special Shampoo (has peppermint oil in it -- what a tingle to your scalp). But, I always come back to this one.
