Hi,
I was reading up on the science of relaxers and I want to post something from Dr. Syed of Avalon Syntonics.
Many times on here, we talk about conditioning your hair right after you rinse the relaxer from your hair with luke warm water as I heard cold water closer hair cuticles. Well, I think that is a great idea because as I read on Dr. Syed's blog, the hair cuticles are about 30% open.
Now, usually I've heard on here that we should use a protein conditioner which I'm sure helps in some way but what I am wondering is if we can include cationic conditioners with this process or alone.
This is what Dr. Syed says about the process of applying relaxers and what I want to focus on is in red:
My questions would be: What do you all think these cationic polymer conditioners that can withstand high heat are...any guesses?
And, if your hair is suppose to be technically wet while relaxing, should you a.) mix the relaxer and the cationic polymers together or b.)put the relaxer on first and then put the conditioner with the relaxer?

This is what Dr. Syed says about the process of applying relaxers and what I want to focus on is in red:
- The pH of the untreated hair is in the range of 4.5 to 6.5 and the cuticles are considered closed, as the hair isn't swollen in the dry state.
- The pH of cream relaxers is around 13.0. When the relaxer is applied to the hair, the pH of the hair increases to 13.0 and the hair diameter swells as much as 60 - 80 percent of its original size. Also, the cuticles become wide open while the relaxer is on the hair. This is the best opportunity to condition the hair because the cuticles are open to the widest possible degree.
Unfortunately, most conditioners are not stable at the pH of 13; especially the single molecules of quaternary ammonium compounds-- conditioning agents used in most conditioners. However, there a select few cationic polymers that remain stable at a high pH, and condition the hair while it is simultaneously being straightened by the relaxer. These conditioning agents are able to penetrate deep into the cortex of the hair and condition the hair more permanently than conventional conditioners. Since the molecular weight of these conditioners is around 1 million, they get stuck in the cortex of the hair when the cuticles start to close during rinsing of the relaxer. Also, these conditioners can stay in the cortex of the hair upto 4 shampooing treatments.
- After 13 to 18 minutes of relaxer treatment, the excessively curly hair generally becomes straight and at that stage, the relaxer is rinsed from the hair with tepid warm water for 4 to 5 minutes. The pH of the hair drops down to about 10 and the hair isn't as swollen as when the relaxer was on the hair. The cuticles are about 30 percent open at this stage. This is the second best opportunity to condition hair in the relaxing process. Since the cuticles are about 30 percent open, the conditioners such as high molecular weight cationic polymers are able to penetrate deep into the cortex of the hair and condition hair from the inside out. This penetration of conditioning agents is less than the penetration of conditioners during relaxing process.
- After rinsing the post-relaxer conditioner with water, the hair is then shampooed with Neutralizing/Normalizing shampoo of pH 4.5 to 6.5. Generally, a high quality neutralizing shampoo contains cationic polymers, mild detergents, organic acids (like citric acid or lactic acid), and color indicators to signal the neutralization of alkaline residue derived from relaxers. The hair acquires the pH of the neutralizing shampoo, that is, it comes back to its natural pH balance while the cuticles close back down to a level that is close to the original state.
