Okay, so I been looking and looking for this stuff. How to remove hat, how to get more hair styles/colors and all I've found is apparently you can't remove the hat, which is kind of dumb imo. It seems to hold true so far, I have seen people without, I think what I found out is apparently they are using default trainer appearances, which I don't know how/where to get those either. I seen purple hair person and I want unique colors, but I think he's using a psychic trainer look, dunno how he did that either tho.
I have read about restyling the hair a lot and tried that, I got a Medium Perm hairstyle(for male, I have a male trainer), and it is kind of like the Medium hairstyle but it curls outward a bit at the ends, if I knew a good way to screenshot I would. I have been using the Style and Color option, and dropped about 50k before she told me "Hello... ... ... Oh! S-sorry! Oh... Silly me... <Trainer>, you look so great... I was mesmerized by you... Ahem... Let me collect myself first... What would you like today?" and proceeded as usual, but when told her Styling and Color and approved the cost, when we began she told me she came up with a new style that was perfect for me or something.
Since then I spent like 100k on restyling and color, and never got a new color, nor any new styles. I always said "Surprise me!" in hopes that helped, dunno if it did, I also hoped maybe appearing before her with certain color/style combos might help, again, not sure if that's what did it or just the spending threshold. Being as I never got a new color, could probably spend half as much just on style changes. I also have noticed since getting the new style when I choose "Surprise me!" I never get the new Medium Perm style, dunno how relevant that is tho.
I'm pretty sad this game boasted trainer customization, and yet it is so lacking. When I chose orange hair, I wanted like a fiery orange like I see many opponent trainers with, but it's a fairly dull ordinary orange... And I remember in older games seeing trainers with green, blue, purple hairs, and even in this game I've seen enemy trainers with purple, bright red, bright orange and many more exotic colors, there should be more styles too. I still wanna know where we might find these default trainer appearances... I keep talking to every person around in hopes of finding it. If I do, you can bet I'll post it here. This is the information I seek most and no one seems to really have it...
Also, if there are 5 styles, how might we get the 5th? Is it just a lot a lot more buying restyles?
