To increase hair density appearance, options include using hair fibers, volume powders, scalp micropigmentation, and a combination of sea salt and holding sprays. Tape-in extensions and clip-in fringes are also considered, but cost and maintenance are concerns.
Hair fibers are discussed as a temporary solution for hair loss, with users noting they work well if applied correctly but can be messy and time-consuming. Some users also use finasteride for long-term treatment.
Sea salt spray adds texture and volume to hair but can dry it out, so it's best used sparingly. Some users find it helpful for thicker-looking hair, while others suggest using it alongside other treatments for oily hair.
The user has maintained hair thickness using oral finasteride and minoxidil for four years, with suggestions to consider dutasteride or a hair transplant for further improvement. Some users recommend trying topical minoxidil with tretinoin or increasing the oral minoxidil dose for better results.
