I have a handout that I picked up at my old salon. It is a professional user guide for the Affirm Conditioning RElaxer System with Protecto. THis is what is printed under the section "How to apply Affirm Conditioning Relaxer System."
If using Moisture Plus dry Hair & SEnsitive Scalp formula, before use, the relaxer creme must be thoroughly mixed with the liquid activator.
Step 1 Protecto Application:
Apply an amount about the size of silver dollar into palm and rub hands together. Gently work throughout entire head of hair, especially to the new growth area. Do not massage to avoid scalp irritation, Comb through gently using shampoo comb to distribute.
Step 2 Creme Relaxer Application:
Apply ample amount of relaxer to thinly-parted sections of hair using an application brush or back of a rattail comb. Begin with the back sections, working downards from the crown area. Proceed to the front sections, working from the crown forward. Apply to the hairline areas last. Avoid applying the relaxer directly to the scalp. For retouches, apply relaxer creme to new growth only. Avoid overlapping onto previously relaxed hair. After application is complete, smooth the relaxer with the back of a rattail comb, using thin partings and working in the same direction as during application. After desired straightening is achieved, rinse relaxer completely from hair with warm water.
Step 3 5 in 1 Reconstructor and/or Positive Link Application:
Affirm 5 in 1 Reconstructor if hair is fine or limp; Positive Link if hair is medium or coarse; 5 in 1 and Positive Link, in half-and-half mixture if hair is slightly damaged. WAit five minuts and rinse hair well.
Step 4 Normalizing Shampoo:
Shampoo all areas of hair and scalp. Rinse thoroughly and repeat. (Lather will be pink if relaxer traces remain, and white when hair is completely neutralized.) Style and Finish with KeraCare maintenace items.
For Affirm Lye in Mild Formula, the timing guide on back recommends 13 minutes.
