I'm currently wearing this one in 12FS8. I have a petite head and face and the density is almost perfect for me. The hair fiber is really soft and fine. I have worn it about 6 times and have not noticed any tangling whatsoever.
If I could change anything it would be:
1. Add a small amount of perma tease in the crown because it is a little bit flat. I back comb in that area to give me that little bit of bump.
2. Thinner density at the front of the face for more realism. I think all wigs should be constructed like this.
3. The ear tabs or area at the temple are a bit long so I wish they were brought back a tad. It almost covers all of my bio hair in that area but I'm still able to pull a little bit of it out.
4. Concerning the color 12FS8: 8 is too dark for someone like me, a natural blonde that has darkened with age. They may say "medium brown" and I've even seen it described as "light brown", but it truly is a dark brown. These blonde wigs with darker roots should have a root option that isn't that dark.
I do recommend this wig. It fits well, moves well, and looks realistic.
