Deep dives
Understanding Hair Loss: Causes and Impact
Hair loss, known medically as androgenetic alopecia, is driven by male hormones that affect follicles sensitive to testosterone. Men start experiencing balding around 30% at age 30, increasing to 40% by 40, while women have noticeable hair thinning at around age 50. The process involves DHT miniaturizing follicles, leading to shorter, finer hair over time. Genetic factors play a significant role, affecting follicle sensitivity to hormones.
Hair Loss Treatments and Solutions
Various treatments address hair loss, including minoxidil and finasteride, which aim to extend the hair growth phase and reduce DHT conversion from testosterone. Topical minoxidil aids in hair growth, while finasteride stabilizes hair loss for many men. Women mainly use minoxidil for treatment, while spironolactone addresses hormonal factors. Hair transplants offer a surgical solution, but emerging therapies like hair cloning and cell-based treatments show potential advancements in the future.
Maintaining Hair Health and Mental Well-being
Hair health is influenced by diet, stress, styling practices, and UV protection. Nutrition impacts follicle health, and crash diets or stress can trigger hair loss. Protecting the scalp from UV rays and minimizing chemical exposure aid in maintaining healthy hair. Taking action against hair loss not only provides empowerment but also contributes to mental well-being. Acceptance and comfort with one's appearance play a vital role in managing hair loss impacts.
For some people, going bald or experiencing thinning hair can have a significant impact on mental wellbeing and self confidence. Madeleine Finlay speaks to Rudi Zygadlo about how it affected him and what he eventually did about it, and to consultant dermatologist and hair specialist Dr Sharon Wong about what exactly is going on when our hair thins, which treatments are available to help, and what we can expect from new technologies in the pipeline.
