Hey, welcome on here! Very good that you freeform, that's the healthiest way getting dreads! But Head n Shoulders is very toxic and has skin irritants (SLS, Sodium Loryl Sulfates) inside which is bad for your scalp. If you live in the States you should order the dreadlocksshampoo advertised on top, it's the best choice for dreads. The liquid is for young dreads, the bars for mature dreads. Seasalt is also good for the locking process!
