My stylist use to do a DRC 28 (heavy duty protein) treatment the SAME DAY as my touch up - after neutralizing and regular shampooing.
I still use this method at home, with no problems.
When it was time for a touch up, I used to bring my Protein Filler. I would get it from Sally's BSS. "Betty" would mix some of it in with the relaxer she used to do my touch up.She would always follow up with a conditioner treatment under the dryer.
I would come away with hair that had body and swang. Not that stick straight thin "just permed" look.
My "Betty" was one of a kind. She encouraged me to bring in the products I used on my hair. She would use them to continue, as she put it, "the good job I was doing with my hair".
Sigh. I miss "Betty". When her husband retired she sold the salon and they retired to Florida.
This is what I do mixed with some moisturizing conditioner.i do a protein treatment (heavy aphogee) 4-7 days prior to my relaxer (to strengthen hair prior to chemical treatment) and i use a mild on reconstructer (aphogee bottle with red writing) after i neautrlize shampoo my hair.
works for me. i then do aphogee every 6 weeks. i try to time it out close to my touch ups.
I do a protein treatment the last wash before a relaxer and the first wash after a relaxer. So it's probably like 4 days before and 4 days after. I also do a protein treatment during my touch-up.
My protein of choice is Ultra-Sheen Duo Tex.
I use it after I shampoo the relaxer out of my hair for no more than 5mn then do a deep conditioning treatment.
