I meant to mention this yesterday. Apologies. When I tried Tweak'd in the past, the issue for me was using the deep conditioner on dry hair. It seemed weird to begin with, but did the treatments until most of the brown jar of finished.
Most other deep conditioners are applied on already shampooed damp hair, so just gets rinsed out. The Tweak'd being applied on dry hair, not washed yet, has to to be shampooed out...most of the deep conditioning benefits, I felt, went down the shower drain.
The shampoos and conditioners are great, just no more tubs of deep conditioner treatments for me.
