This extra rich Curl Defining Leave In hair conditioner is made from naturally derived ingredients, and several organic ingredients. Can be used every day by those with dry to extra dry hair. Many people ask us if this will work as a 'leave in' conditioner? Yes, it will for most hair types. Those with thin, fine hair probably should use this as a normal wash out product, but for all other hair types, it can be left in. Those who have tested it as both a leave-in and a wash-out conditioner, rave for its ability to soften the hair without weighing it down. As a leave in: just remember a little will go a long way!
