Cosmetic treatments for hair loss are by definition impermanent and reversible, so those aspects of cosmetic treatments will not change in the future. But other improvements will certainly be made. In the future, there will likely be hair-styling products that give a much more powerful appearance of a full head of hair, when compared to today's hair-thickening gels and hair shaft-coating mousses. Hairpieces and wigs currently have the disadvantage of expensive and time-consuming ongoing maintenance and replacement, and their use continues to include a significant fear of detection. In the future, cosmetic hair appliances such as hairpieces and wigs will likely be constructed of even finer and more durable materials, which will appear and feel even more genuine, and be even less detectable. Attachment methods will continue to be very secure, but may also become easier and faster to release, reducing maintenance effort, and improving hygiene.
