Hair can be connected to generational trauma through its physical markers, like elevated hair cortisol levels linked to chronic stress, and its cultural and social significance, such as how beauty standards or hair care practices can carry the weight of past trauma. Trauma can be passed down through generations via stress-related physiological changes, while social pressures related to hair, like those faced by Black women, are inherited from historical racism and can perpetuate a cycle of trauma and inauthentic self-expression. 

Biological connection

• Hair cortisol: Studies show that maternal experiences of trauma are associated with increased hair cortisol concentrations in their children, a biological marker of chronic stress.
• Cross-generational effects: This suggests that the stress from trauma can impact a child’s ability to regulate their behavior, emotion, and cognition through physiological pathways passed down from a parent.
• Long-term stress marker: Hair provides a long-term record of cortisol levels, allowing researchers to study the cumulative effects of stress over time and how it can be transmitted across generations. 

Cultural and social connection

• Inherited beauty standards: Generational trauma can be passed down through cultural expectations and beauty standards related to hair, such as the historical pressure on Black women to relax their natural hair due to racist ideals.
• Impact on self-esteem: These societal pressures can lead to intergenerational cycles of trauma, where individuals change their hair for social or professional reasons to avoid discrimination, which can be emotionally damaging.
• Aesthetic trauma: This is a term used to describe how trauma can manifest as a compulsion to conform to certain beauty standards, leading to behaviors like constant dyeing or chemically straightening hair, even when it negatively impacts health.
• Talisman of identity: For many, hair is not just a physical trait but a powerful symbol of identity, cultural heritage, and personal experience, making it a significant site for healing and reclaiming one’s story from generational trauma. 

Examples of intergenerational impact

• Mother-daughter relationships: The transmission of racial trauma through hair care and socialization can be seen in the complex relationships between mothers and daughters, where hair care becomes a way of both celebrating and perpetuating generational legacies.
• Recreating past experiences: Sometimes, someone may unconsciously replicate past painful hair care experiences, like being told to be still, which can be a manifestation of unresolved trauma.
• Healing and rebellion: Choosing to embrace one’s natural hair can be an act of rebellion against the generational pressures to conform, a step toward healing and self-acceptance.
