More than ever, hair care is being shaped by the broader shift towards prevention and long-term wellbeing. Industry research shows younger consumers, particularly in their 20s and 30s, are prioritising preventative scalp and hair health over reactive treatments, driving growth in longevity‑focused routines and products.* In particular, the term ‘hair longevity’ has been gaining recent traction, with searches in the UK up 87% in the last month alone.
But how does hair actually age, and what steps can be taken to protect it before thinning or loss occurs?
Dr. Abdulaziz Balwi, leading hair surgeon at Elithair says:
What are the key biological drivers that cause your hair to age?
“Hair ageing is a multifactorial biological process affecting both the follicle and its environment. Over time, follicles miniaturise, producing finer, shorter hairs with a reduced growth phase. This is driven by factors such as hormonal sensitivity, reduced blood supply, oxidative stress, and low-grade inflammation. In parallel, a decline in melanocyte activity leads to greying (canities). While greying and thinning often occur together and share underlying contributors such as oxidative stress, they are distinct processes and can develop independently, reflecting a broader decline in follicular regenerative capacity.”
How does “hair longevity” differ from existing concepts like scalp care or anti-hair loss treatments?
“Hair longevity reflects a shift beyond traditional scalp care or anti-hair loss treatments. Rather than focusing solely on cleansing or reversing loss, it centres on preserving follicle function over time. It takes a preventative, systems-based approach, addressing inflammation, circulation, and cellular health before visible decline.”
What innovations are currently shaping this space?
“In terms of innovation, we are seeing progress in several areas. There is growing interest in bioactive peptides, exosomes, and growth factor-based therapies that aim to support follicular signalling. Advances in regenerative medicine, including platelet-rich plasma and stem cell-derived approaches, are becoming more refined. On the topical side, formulations are incorporating antioxidants, barrier-supporting compounds, and microbiome-balancing ingredients to help protect and maintain follicle health.”
Are consumers becoming more preventative in their approach to hair health?
“Consumers are certainly becoming more preventative, with younger patients seeking guidance earlier and showing greater interest in maintenance strategies. Early intervention is increasingly seen as key to preserving hair quality and density. Examples of these preventative approaches include starting bioactive complexes such as Redensyl, Capixyl, or Procapil that support follicular anchoring, incorporating antioxidants and scalp-nourishing ingredients into daily routines, and using low level light therapy or gentle microstimulation devices to maintain follicle activity. “
What are the best ways to slow down hair ageing?
1. Support follicle health through nutrition and lifestyle
Make sure you get enough protein, iron, zinc, biotin, vitamin D3 and essential fatty acids, as these nutrients are essential for strong, healthy hair. Managing stress and getting enough sleep is important because chronic stress can trigger inflammation that weakens follicles.
2. Protect against oxidative stress and environmental damage
Protect your hair from UV light and pollution, which can accelerate greying and weaken follicles. Include antioxidants in your diet, such as berries, leafy greens, and green tea, and look for topical products with antioxidant ingredients to neutralise damaging free radicals.
3. Maintain scalp health
Keep your scalp clean and well moisturised, as this reduces irritation and inflammation that can harm follicles. Using products that support a healthy scalp microbiome helps maintain the right balance of bacteria, creating an environment where hair can grow stronger and healthier.
4. Use targeted medical and regenerative approaches
Consider treatments such as low-level light therapy, platelet-rich plasma, or growth factor-based therapies to support follicle function. Starting clinically proven topical or oral treatments early can help slow thinning, maintain hair density, and protect the follicles over the long term.
5. Avoid unnecessary damage
Be mindful of harsh chemical treatments, excessive heat styling, and tight hairstyles, as these not only place stress on follicles but can also accelerate hair ageing. Gentle hair care routines help protect the cuticle and scalp barrier, supporting long-term hair quality and resilience.
