Hair shouldn't be an excuse for not taking care of your body. A healthy body will grow a healthy head of hair. Sidenote: 150 hours a week?? There are only 168 hours in a week. I'm going to assume there should be a decimal point in there somewhere.
I gave up living around my hair three years ago, by working with my natural texture. I realized I could do more living if I cut out the time I was spending trying to maintain an artifical look. The result: more money, exercise, and less worrying. Sometimes, I run into people who have an "opinion" about my choice, but I let them worry about that and keep it to moving.
