Chemical relaxers and alkaline straightening treatments are among the most aggressive processes hair can undergo — with pH values between 12 and 14, comparable to drain cleaner, they irreversibly break the strongest bonds of the hair fiber. This is exactly where pH Plex comes in: with its globally patented Malic Acid Complex and the specially developed pH Plex #3 Stabilizer for Relaxer, the brand offers the first and only Plex product formulated specifically for relaxed hair.
Why Relaxers Damage Hair So Severely
Chemical relaxers rely on sodium hydroxide, calcium hydroxide, or thioglycolates to break the disulfide bonds in keratin and permanently stretch the curl pattern. At pH levels of 12–14, the cuticle swells dramatically and disulfide bonds are converted into lanthionine — an irreversible chemical reaction that locks the hair permanently into a less stable form. The consequences are dramatic: super-contraction of over 35%, loss of elasticity, dryness, breakage, and in the worst case even scarring alopecia.
What Sets pH Plex Apart
While classic bond builders address only the disulfide bonds, pH Plex’s patented Malic Acid Complex binds to all 21 amino acids of keratin, stabilizing the hair fiber on a molecular level more comprehensively than conventional competitor products. Particularly important during relaxer treatments: pH Plex actively controls the pH value in a measured way, rather than letting it rise unchecked into the strongly alkaline range, thereby protecting both cuticle and protein structure throughout the chemical process.
The pH Plex #3 Stabilizer for Relaxer in Detail
According to the manufacturer, the pH Plex #3 Stabilizer for Relaxer is the world’s first and only Plex product developed explicitly for use with relaxers. This nourishing cream is a weekly in-between treatment that intensively stabilizes, hydrates, and molecularly strengthens relaxed hair between applications. Formulated with Malic Acid Complex, antioxidants, bonding actives, and nature-identical ingredients, the product is vegan, cruelty-free, and dermatologically tested.
Who Is the Relaxer Range For?
The target audience is people with chemically straightened hair who want to minimize follow-up damage and preserve the results of their relaxer treatment long-term. Because pH Plex is tuned to the natural pH of hair and skin (4.5–5.5), it is also suitable for sensitive scalps — a key advantage, since relaxer users frequently suffer from irritation, redness, and itching.
Application at a Glance
- During the relaxer treatment: mix pH Plex #1 Protect directly into the relaxer cream — without changing the mixing ratio or processing time
- Immediately after rinsing: pH Plex #2 Repair for instant aftercare and fiber stabilization
- Between relaxer appointments: pH Plex #3 Stabilizer for Relaxer once a week as a treatment to strengthen hair on a molecular level
- Interval: relaxer touch-ups should not be performed more frequently than every three to four months to avoid overlap and breakage
pH Plex Relaxer System vs. Standard Bond Builders
| Criterion | pH Plex Relaxer System | Classic Bond Builders |
|---|---|---|
| Bonding mechanism | All 21 amino acids of keratin | Primarily disulfide bonds |
| Dedicated relaxer product | Yes, #3 Stabilizer for Relaxer | Generally not available |
| pH control during treatment | Active pH control | Variable |
| Certification | Vegan, cruelty-free, dermatologically tested | Depends on manufacturer |
| Patent status | Globally patented Malic Acid Complex | Inconsistent |
Takeaway for Relaxed Hair
Anyone who regularly uses chemical straighteners or relaxers needs more than conventional care — what’s required is a system that stabilizes the fiber on a molecular level both during and between treatments. With its patented Malic Acid Complex and the purpose-built #3 Stabilizer for Relaxer, pH Plex delivers exactly this specialized protection, positioning itself as a unique solution in the segment of alkaline-straightened hair.
