Chemical relaxers operate at pH values between 12 and 14, breaking the strongest bonds in the hair fiber, permanently altering its structure and making it highly prone to breakage. With pH Plex Relaxer, hairdressers worldwide now have access to a patented plex system specifically formulated to the pH value of lye and no-lye relaxers, controlling bond breakdown during the smoothing process.
Why Relaxer Treatments Demand Specialized Protection
Lye relaxers (sodium hydroxide) and no-lye relaxers (calcium hydroxide/guanidine carbonate, lithium or potassium hydroxide) are highly alkaline and irreversibly convert the hair’s disulfide bonds into lanthionine bonds. This causes the cuticle to swell dramatically, leading to loss of elasticity, dryness, dullness and breakage. No-lye formulations may be gentler on the scalp but are often harsher on the fiber, leaving residues and offering no protection against bond destruction.
What Makes pH Plex Relaxer Unique
According to the manufacturer, pH Plex Relaxer is the FIRST and ONLY plex product specifically developed for ALL relaxer types — both lye and no-lye systems. The formulation is precisely matched to the pH value of relaxers and is worldwide patented, integrating seamlessly into existing salon workflows. The goal: prevent unwanted hair damage during treatment, stabilize hair structure and visibly improve shine and hair health.
