The Science of Healthy Hair, Hair Loss and How to Regrow Hair

In this episode, we delve into the biological foundations of hair and its growth processes, elucidating the reasons behind the deceleration of hair growth and the factors leading to hair loss or cessation of growth. We explore the crucial function of hair stem cells and other biological contributors essential for the maintenance of healthy hair. Various methods to decelerate hair shedding are discussed, encompassing both mechanical and chemical strategies aimed at enhancing blood circulation to the hair stem cells, such as the use of minoxidil, tadalafil, PRP, microneedling, Botox, and ketoconazole. The episode also examines the impact of age-related hormonal shifts on hair loss and assesses the efficacy of treatments like caffeine, saw palmetto, growth hormone, finasteride, and dutasteride. We cover the potential side effects associated with these hair growth strategies, the anticipated timeline for observing results, and the expected extent of hair regrowth, including the effectiveness of combined treatments in revitalizing even the inactive (bald) areas of the scalp. Recognizing that issues like thinning hair, brittleness, or pattern baldness can significantly contribute to anxiety and stress for many, this episode aims to demystify the scientific principles behind hair regrowth techniques, enabling listeners to make informed decisions about treatment options and their possible side effects, and to choose the most suitable approach(es) for themselves.
