I totally forgot to answer your questions, I'm so sorry!
The hair from my profile picture unfornatly I can't find it, and hovering my mouse on it's icon doesn't give any clue from who it is (if someone remembers from who it is plsss)
The hair from the frist post it's from minicule and it's called Elenora, you can find it here: https://miniculesim.tumblr.com/post/656024741783764992/clumsyalien-eternity-cc-pack-4t2-conversions
The hairs from the second post are from hazelpuff and are called Marjorie and Lyla, you can find it here: https://hazelpuff.tumblr.com/post/640304423976992768/4t2-marjorie-lyla-hairs-4-colors-binned-7
Any questions feel free to ask! π
