Can’t get some hair color drops

[Ms. Lee]

Specifically, I can’t seem to get the fourth hair color drop for some of the characters I have. After reading many guides and discussion topics, I couldn’t find an answer or a clue. I’ve had the first six DLCs for a while now, but I’m still missing that fourth hair color for some of them. It’s not limited to DLC characters either. For instance, I still don’t have Poppo’s fourth hair color. A few weeks ago, I bought the Breaker DLC and I already have all of Sweet’s cosmetics unlocked. Even if they are random drops, I’ve played way too many games online way too many times with the characters, and that includes Poppo too. Does anyone know if there’s a specific circumstance to unlock the fourth hair color? Needless to say, apart from that fourth hair color, I have everything else for the characters I have unlocked – at least everything that would drop after an online game.

As far as I'm aware, for most characters only the hair color listed as #1 has a specific unlock condition attached to it (which is to play 10 games online as that character).
#2, #3 and #4 are random drops after online matches. I remember one of the three having a significantly lower drop rate than the others, although you can get any of these three hair colors even while playing as a different character.
#5, #6, #7 and #8 are all bought with oranges from the 50 crate or directly from the in-game shop at a premium.
Krila's #9 is the only other hair color I'm aware of that has a hidden unlock condition to it.

You’re totally right. I learned all of it as I searched for clues. Apart from Star’s first hair color (since I’ve yet to play 10 online games) and Krila’s bonus hair color (since I can’t keep track of how many robo balls I’ve killed while wearing the sunglasses), I’m still missing Tomo’s, Sham’s and Poppo’s fourth hair color. It’s just that, before buying the Breaker pack, it had been months since I got a drop of any kind. I was hoping maybe I could find someone who could relate. Even so, given the amount of games I play every day, they should’ve dropped already. :< Well, thanks for your answer.
