Hair Growth vs Anti-Shed Serums: Expert Guide to Ingredients and Use
An article from Vogue distinguishes between hair growth serums, which enhance new hair development and thickness, and anti-shed serums, which minimize hair loss. Dermatologist Sejal Shah emphasizes that these two types are not the same. Growth serums extend the anagen phase by utilizing growth factors such as exosomes or minoxidil, along with components like L-arginine and peptides. In contrast, anti-shed serums curtail the telogen phase by blocking 5-alpha reductase, featuring ingredients like aminexil and treatments like finasteride. Experts Kaveh Alizadeh and Paul Chasan contribute insights. Featured products include K18 FutureIQ Serum ($120), SickScience Exosome Serum ($64), and Pantene Scalp Serum ($24). Dr. Chasan recommends regular use, comparing it to maintaining an exercise regimen. The article appears on Vogue's website.
