That is way too long. I read a Q and A on this site a while ago with Ouidad about this very thing. She told the woman asking the question that hair may take longer to dry if the overall condition of the hair is dry. According to her answer, once the internal moisture of the strands are adaquate, drying time should decrease. I have to say at the time this sounded absolutely ridiculous to me but I have noticed that my drying time has dramatically decreased as my hair has gotten healthier. Before being CG my hair would take 8-10 hours to dry. Now my hair takes 2-4 hours to dry (4 if I am indoors during the entire drying time).

This is a link to the Q and A. If if doesn't work you can find it by searching "hair takes too long to dry" and looking in articles. HTH
