Longevity Is Booming in Beauty—Here’s What It Means for Your Hair Routine

Over the last couple of years, the practice of longevity has become almost impossible to escape, especially in beauty and wellness. In skincare, it has inspired age-defying serums, NAD-boosting creams and supplements designed to extend the life of skin cells and preserve a youthful glow. In wellness, it has manifested as biohacking routines that promise not only longer lifespans but healthier ones. The next area embracing this shift? Hair.

What does longevity have to do with hair? Actually, quite a bit. Not in the way that it impacts our lifespan, hair longevity is concerned with the way hair and scalp ages, how it responds to stress, and staying strong and healthy. If longevity is about optimising overall health, it makes sense that it would also apply to hair—and more specifically, the scalp. We’ve seeing brands like K18, Hårklinikken, monpure and Act + Acre incorporate the practice into their ranges from cold processed stem cell serums that sends signal to your scalp to supplements that address stress, gut imbalance and nutrient deficiencies to promote hair growth. Haircare as we know is changing.
