Thanks for your thoughtful replies, Leti. I particularly appreciate the attention to community engagement around data collection in the course of your second generation work - this speaks to the importance of this engagement across the range of research activities. And maintaining the fourth generation lens is challenging, but as you noted in class, essential, including the self-reflection aspect.
Beauty salons are obviously a great parallel to barbershops for men, in more ways than one, and particularly useful given your focus on hair samples. There may be interesting considerations for men vs. women around the frequency of visits to these institutions and the amount of time spent there at any given time. For example, some women may have longer waits for hair treatments, and this time could be used for some empowerment or health education activity.
