I received my Halos not long ago. I love the quality of the hair. I ordered the 160g and I have short to medium length hair, which is thin in nature. When I first installed the Halo I felt them too heavy on my head and a bit uncomfortable, but this is probably because I am not used to them as this is my first ever hair extensions set.
The colour match is a bit darker than my natural hair, at least the top layer. I would say the bottom layer is very similar colour. I think the difference from my natural to my Halo can definitely be seen when I wear it, which is slightly disappointing.
The instalment: I am still learning how to install the Halo the right way. Every time I wear it the wire slides at the back of my head. If I somehow make it stay, it feels super tight and I get headaches. Thats why I had to use the XL wire (the wires have sizes, which is super helpful) and it feels comfortable.
Overall, I think they are good quality extensions. It will take some time to get used to wearing them and styling them but it is all worth it for having long hair.
