From what I've seen in pics, I think that Beaute Speciale does some great work. I was impressed with all of the brides that I've seen on here that have used them! I think as long as you bring pictures of EXACTLY what you want and are very descriptive you should be fine without a trail.....
With that being said, let me tell you a story....
For my sisters wedding (I was her MOH

) she had a friends sister who does hair come out to the house and do our hair the morning of the wedding. My sis had a trail a few months before the wedding, but I did not. When it was my turn to get my hair done, I sat in the chair and she asked me what I wanted done. I told her: "I'd like a side part that sweeps across... up with loose curls pinned up."... So she goes to work on my hair, teasing it, then combing it, then teasing it... my head is being yanked in all different directions. Finally I feel her scoop my hair in a pony, and she starts to curl and pin and tuck. When she gave me a mirror to look at the finished product, I ALMOST HAD A HEART ATTACK!!! I dont know what part of my description of how I wanted my hair said: "Pile my hair on the top of my head in a pyramid shape with one curl at the top," but that is literally what it looked like. I was mortified! My mom saw the horror on my face and asked me if I was 100% happy with it, and the hair lady said, "IF you want me to change something just let me know"... she was actually really nice and just wanted me to be happy with it, so I nicely said, maybe we can do a few loose hanging curls? Maybe not so tight."
So she started unpinning King tuts tomb and when she was done I was still not 100% happy, but it was better. I don't remember at what point I started to get upset about it, I think it was a few minutes later when I went into the bathroom and really saw in a big mirror just what I looked like... I really got upset and started to cry, my mom is yelling at me b/c I had just gotten my makeup done and it was going to smudge which just makes me more upset! My sister comes in and is trying to calm me down. At this point we are almost all ready to go and take the pictures! So finally my sis sits me down on a stool in the bathroom, she whips our our curling iron, and in her wedding dress, tiara and veil starts to fix my hair! When we look back on it, we just laugh b/c here she is on her wedding day, with enough things going on and stressing about, and she's doing my hair! After all was said and done, my hair was "nice", but certainly not what I wanted at all.
So for my own wedding there is NO way I'm not doing a hair trail, but that is just because of the horrible experience I had. Also, this lady definitely did not do wedding hair on a regular basis, and she was very young. I think that, on top of not being descriptive enough to her was what did me in!
