All eyes on you!
Color: DR2GDNHN, Color: DR2GDNHN
I didn't love this wig straight out of the box but after trimming the wig to frame my face and brushing out the curls (I love big hair), I absolutely fell in love with this unit. I've received so many compliments. Wig does tangle but after applying product the curl pattern returns. Will definitely purchase again!

Gorgeous wig, big head friendly
Color: 1B Off Black
I loved this wig, I have a huge head and have to return now wigs I buy. But this was a keeper, it's synthetic so don't go crazy expecting human hair realness. In the sense that it will tangle in the nape. I detailed and then cut off the undesirables. But for the prize, it worked as half wig with a headband. For the price you can't beat it. I gelled the front alittle and I looked like Selena. Lol if you know the reference then you know. But it looked great with a headband. I wore it on vacation it wasn't too hot, it wasn't exactly cool either. But it was good. For the price I'm buying a few more in other colors. I didn't make it a ponytail yet but that up next.

Decent for the price
Color: 2 Dark Brown, Color: 2 Dark Brown
Bought the color 2 thinking it would be brown but it’s almost Black (my own ignorance). I saw a YT vid by Kie Rashon where she sort of left the front of her hair out so I was hoping to do the same but it’s too dark for my hair (you can’t tell in the pics). I would recommend checking Kie out on YT for more details. I do like it though so I will probably give this one to my sister and reorder a different color. Wish they provided pics of how the wig in other colors look. Edit: So I repurchased this piece in DR Hazelnut Brown (the lighter color). I took some leave out in the front so please note that’s my hairline, not the wig’s. It blended well with my hair color. My texture is a little curlier but I just did a braid out on the front to help it blend. Wig tangles very easily. I’m going to experiment with co-washing to see if that reverts it to its origami condition.
