I have been dyeing Tibetan lamb hair of over two years now with a lot of trial and error.
This conditioner is the best.
There will be no oily build up and will absorb into the Tibetan Lamb hair and Mohair. If you have some Tibetan lamb hair that seams dye and not shiny don't throw it away bring the softness and shine back with Gertrude's Conditioner.
Damp hair add about a dime size or less in the palm of your hand rub hands together and apply. Works best when hair is wet I have used it on dry hair also.
Do not wash out.
This will not work on synthetic doll hair only for Natural Tibetan Lamb Hair or Mohair.
