The tutorial I refer to is ''How I Perm My Eye Lashes' by Lily Seymour, which @DNLee alerted me to. The relaxer used in Seymour's video, and discussed in my video, is
Optimum Multi-Mineral Reduced pH Creme Relaxer from SoftSheen-Carson. BeautyVirus provides images of this product which detail its ingredients and instructions.
