They are now available in Lan Forta (Scissorhands npc) with the exception of the thief skin. ;3
In general, the first and the second rows of skin are the default skin; Row three and row six are available for 500,000 zenny or one hairshop coupon (In item mall, 10 coupons = 20 rubies or in battlefield npc, Raven Paul, for 1 coupon? = 200 Fame); The rest like row four, row five, row seven and row eight can be purchased for 35 hairshop coupons only (so that's approximately 80 rubies I think/7000 Fame?).
Finally about changing hairstyle/hair color, there's nothing new about them (as of now?). It's the same as when you're creating a new character.
