The rim of the bathtub and the top of the mirrored cabinet were crowded with products for dry or damaged hair. I saw a deep recovery healing shampoo for deep damage repair, a dry remedy moisturizing mask for damaged curly hair, a total repair conditioner for hair damaged and dried by styling products, an ultimate moisture conditioner for very stressed hair, and a bottle that just read EMERGENCY TREATMENT: HAIR DAMAGED BY DRYNESS. I stood under the shower, luxuriating in the hot water yet troubled by a mounting sense of unease about my relatives’ hair.
