I prefer wigs because like many have already mentioned, they're way more convenient than the salon hair. They also tend to have more effort put into them that makes them look better for the most part.
That said, I think some of the salon hairs are pretty neat! I originally intended to stick to one of them since it's the closest I can get to my OC's hairstyle--this name is hers!
I eventually decided to play around with my inventory; I had gone a little crazy in getting a bunch of Ship Going Down RIGs, and I had cool finds from the dumpster and fell in love with a certain combination:
And that's how the hair from the Saber Faedae item became my 'default' hair. It was a dumpster dive find and I will forever thank that person for their generosity everytime I log on.
After a while though, sticking with the same hair became kind of boring, but I absolutely refused to switch the iconic hair. The solutions that Gaia thankfully has for this are the scissor items like Agape and hair extensions~ Bangs are the best (using lots of Adorkable Bea bangs recently), but I'd like to get my hands on more ponytails, pigtails, etc.
Check out what I managed to do while keeping Saber Faedae on~
