Sugary foods can lead to spikes in your blood sugar levels, which trigger the release of insulin. Elevated insulin levels can then cause testosterone to become more readily available, as it is released from binding proteins. This increased availability of testosterone can lead to its conversion into dihydrotestosterone (DHT), a hormone associated with hair loss.
By reducing your intake of sugary foods, you can help maintain more stable blood sugar levels and potentially mitigate the risk of excessive DHT production, promoting better hair health.
