Do I need salt to dye thermofiber w/ Rit?

Hey, I remember Amm's post when she dyed 613 elite thermofiber with tan and dark brown Rit..... she said the liquid Rit didn't need salt, but the granular form did need salt. I'm about to dye my 613 elite thermo that I got from amm, but when I purchased the Rit, it says on BOTH the liquid (which I have in Tan) and granular (Dark Brown) packages that salt should be added for "best results when dyeing cotton, rayon, linen, ramie, or blends of these fibers".

I wouldn't have thought that the thermal synth would be made of any of those types of fibers needing salt. Any advice? I'm about to start experimenting on the stovetop, so I'd appreciate any notes/recipes/measurements anybody made while they were dyeing their thermal fiber.

Gawd, this is gorgeous hair.... for synth hair, I wish MY hair looked this good. And it feels good too, not rough. The 613 is simply too light to blend with a darker color to match my hair, though..... so I've either gotta dye the 613 or dye my hair, and a box of Rit is cheaper than a trip to the hairstylist! I hope to post my "recipes" and photos of results when I'm done, so that others may benefit.... I believe I've heard others on the board say the elite thermo didn't match their hair, so they couldn't use it. I'm hoping I can use this hair, or I'll cry, cuz it's beautiful. Also hope to take some "carrot"iness out of the 27 color.

Awesome, Poose! May I ask, why the vinegar soak? What does that do?

For dying natural fibers, vinegar is used in the dye bath. Natural fibers grab the dye better when they are dyed using a more acidic dyebath . Synthetic fibers grab dye differently and therefore do not need vinegar in the dyebath.

The Rit dye you find in your local stores is a multipurpose dye (meaning it is meant to dye all sorts of synthetic and natural fibers) The salt in the dyebath is a catalyst which is meant to help the fiber grab the dye better..
