I hate this shampoo. It smells great! It almost smells too strong. You know how you smell a shampoo and it is so potent that you know it will irritate your scalp? Yeah, it does. And it supposedly good for dreadlocks... but that is crap. It irritates my scalp so bad. You do not need any special or specific shampoo for dreadlocks, that is a load of crap. Use what shampoo works for your scalp so you don't end up with scalp irritations, just rinse extremely well. That is the basic way to avoid residue in your dreads, rinse rinse rinse. Usually, residue free shampoos or shampoos specific for dreads cause scalp problems.
