Extensions in Chicago?

Are you wanting longer or thicker? Maybe both?
I use the lord & cliff method myself. It is hard to work around a receding hairline. If the hair is fine you may be able to see the bonds thru it. Thats definitly not cool.
You may have to go with bangs.
The reason why I'm thinking that is because I have a client with a thin hair line. We gave her some bangs, I cut them on a angle sloping gently. (they are making a come back) They are still a soft long bang. Anyways, we ended up able to put some extension around the hair line because she had enough hair from the bang I cut to cover the bonds. I also used a a smaller amount of bond and hair when applying for a more natural effect. This was a experimental thing but it worked out really good and she is very pleased. I must stress that if your hair is weak from meds or anything like that. bonded extensions may not be right for you.
Another alt would be clip in bangs.
