need 101 for synth

Thank's guy's !  at least ordering this and getting a wrong color wont result in my morgatge being late!!!! My sheding happend when I used latex and coated it with nail glue for shrinky install. Now I'm using epoxy no shedding this stuff is strong!!! I can't wait to try synth.. Allthough a client of mine with virgin hair my color let me keep the 10 to 12 inch pony I sniped off her!! I wish it was a tad longer its soooo soft.

Marie, if your weft sheds - Bohyme or any other - put superglue along the weft before you install it (let it dry first). That's almost a given with wefts. They shed like a big dog or small fuzzy cat.

As far as colors...girl, welcome to the club. It's all about research. You should see the BOXES of hair I have of all types - synth, hh, straight, curly, wavy...and all in the dark browns like you. The most beautiful colors I loved the most - a real deep coffee brown and a gorgeous REAL chocolate - was by Trimco, but I don't like the texture of the hair. But...it's a standard by which I judge other hair's colors.

My suggestion is to go back and read lots and lots of posts on the board (it takes days). You'll learn a LOT and give yourself time to figure out what you want, what's out there, what's been done...

The long and winding road.

Which is best depends on what you want the hair to do. 

If you need to style your hair with a straightening or curling iron every day then you probably want a thermal like Wawa or Ebonyline or Hot Stuff Fusion.
If you need hair that has some curl/wave to it to begin with but won't need to survive heavy appliance use PH has a huge range of colors and can be ordered in practically anycurl you want if you can wait for a special or der or comes standard in Straight, 50mm wave, and 28mm curl.
Other monofibres (plastikhaar is a monofibre) like Dome, Trimco, Prostyles may have slight advantages or disadvantages over PH I don't know.

If you wash your hair (particularly in the case of PH/mono) in cool water rather than hot you can avoid losing the curl quickly.  Even if you do lose it in the  mono's it can be put back.  You can use a curling iron on it but you have to be more careful.

The numbers?  As in color numbers or 50mm, 28mm?
1 = Jet Black
1b = Off Black
2 = Very Dark brown
4 = Dark brown
613 = Light/platinum blond.

OR 50mm is hair that the diameter of the curl is 50mm.  ~ 2 inches  uner its own weight it is curly like that at the ends and wavy headed to straight as you go higher up
28mm has a curl of diameter 28mm 1 1/8"

Lots of people like combinations of different synths say PH in the back and thermal in front.

Ask more speciffic questions I shall try to provide more speciffic answers
