Brown Towel

Barb is very protective with her bath towel.  She says my towel starts to smell like my oily hair after a while because I wet my whole head every morning if I am not taking a shower.  I forget and just use the closest towel available.  Barb told me that I should use the brown striped towel and her towel was the completely brown towel but I keep forgetting and do not notice I am using the wrong towel until I have already dried my hair.
