Introduction Humidity can wreak havoc on hair, causing frizz, flyaways, and a general lack of manageability. As healthcare professionals, advising patients on the best products to manage these common hair concerns can be a valuable part of holistic care. This comprehensive guide aims to provide detailed information on the best humidity defense sprays available in the market, ensuring you can offer informed recommendations to your patients. Understanding the Impact of Humidity on Hair Humidity affects hair by increasing its moisture content, leading to swelling of the hair shaft.
