Thank you all for the compliments.
They are keratin-tips. Took more hair than "normal" to blend because my hair was so short. A "normal" head there are about 5 bundles of tipped hair; they used 7 on me.
I really think the stylist did a great job because on average, my hair was only about 3 inches long. The general recommendation for good blending is 5 inches to start.
The woman I went to 5 years ago actually sold the salon (I went to the same salon, ownership changed), and began distributing her own line of hair which they used on me. It is called Vision Hair Extensions, and I was able to get it for $105 per bundle installed. The salon does most other "major" lines such as Great Lengths, So Cap, Mega, etc. To compare costs, So Cap are $160 per bundle, and Great Lengths are $250 per bundle.
I paid $735 (7 bundles at $105) plus tip; some people think that sounds expensive and it's not cheap, but when I call around, most places don't have quotes starting below $1,200 minimum. So Cap at the same location would have been over $400 more, and Great lengths would have been a LOT more than that.
The other benefit at this particular salon is that they have access to a lot of Vision Hair stock, so we could color match more easily than having to order and wait for one of the other lines.
