Hong Kong's humid climate can lead to clogged hair follicles and accelerate hair loss if cleansing or moisturizing is insufficient! By the way, after analyzing the causes with my help, this friend started using products and a hair-washing routine suitable for their hair type, and their hair gradually grew back (faster than expected)! Having hair means there's a solution! (If hair loss becomes severe, I also know someone at "Hair Regeneration" who I can refer you to 👌)
