The pH Plex #3 Stabilizer for Relaxer is the first globally patented Plex product developed specifically for relaxed (chemically straightened) hair — a weekly treatment that stabilizes, hydrates, and strengthens the hair on a molecular level between relaxer applications. In this article, you’ll discover why this innovation from the pH Plex Relaxer line is a true must-have for anyone who wants to keep their relaxed hair healthy, shiny, and manageable.

What Is the pH Plex #3 Stabilizer for Relaxer?
The pH Plex #3 Stabilizer for Relaxer is a nourishing crème from the pH Plex Relaxer line and, according to the manufacturer, the first and only Plex product designed specifically for use with relaxers. Formulated with the globally patented Malic Acid Complex, antioxidants, bonding agents, and nature-identical ingredients, the product is vegan, cruelty-free, and dermatologically tested.
One tube contains 150 ml (5.0 fl. oz.) and — like the entire pH Plex range — is made in Germany.
Why Relaxed Hair Needs Specialized Care
Chemical relaxers break disulfide bonds within the hair’s structure to permanently loosen its natural curl pattern — a process that puts significant stress on the hair. Plex products are specifically designed to protect or rebuild these bonds, helping to prevent breakage, porosity, and loss of shine.
Between relaxer appointments, hair continuously loses moisture and structural integrity. This is exactly where the #3 Stabilizer for Relaxer comes in — replenishing active ingredients between treatments and supporting the hair’s natural pH level.
Key Benefits at a Glance
- Weekly treatment that infuses hair with moisture and nourishing antioxidants
- Replenishes active ingredients between two relaxer applications, extending treatment results
- Helps maintain the hair’s natural pH balance
- Strengthens hair on a molecular level and rebuilds bonds
- Leaves hair healthy, smooth, and shiny
- Built around the globally patented Malic Acid Complex technology
Ingredients: What’s Inside the Tube?
The formulation combines conditioning, nourishing, and bond-strengthening components. Key ingredients include Sodium Malate (the signature malic acid actor), Cetyl Alcohol, Polyquaternium-37, Guar Hydroxypropyltrimonium Chloride, Tocopherol (Vitamin E), Amodimethicone, and Behentrimonium Chloride. This blend delivers deep conditioning, detangling, smoothness, and antioxidant protection.
How to Use: It Couldn’t Be Easier
The #3 Stabilizer for Relaxer is applied once a week for 10 minutes to keep hair healthy, hydrated, and shiny.
- Shampoo the hair and towel-dry until only slightly damp
- Apply the product evenly from mid-lengths to ends on clean, damp hair
- Leave on for 10 minutes, then rinse thoroughly and style as usual
This weekly at-home routine is crucial because it maintains the Plex protective effect until the next salon visit — a principle that has proven itself throughout the Plex universe for years.
Who Is This Product For?
The #3 Stabilizer for Relaxer is designed specifically for people with chemically relaxed hair who want to preserve the results of their relaxer treatment long-term and protect their hair from follow-up damage. Since pH Plex is formulated for all hair types and aligned with the natural pH of hair and skin, it’s also suitable for sensitive scalps.
pH Plex in the Bigger Picture
pH Plex is a globally patented hair protection system with a distinctive pH value, offering maximum protection and repair for damaged, dry, stressed, and over-processed hair — both during and after chemical treatments. With the Relaxer line, pH Plex now consistently extends its technology into a previously underserved segment of the hair care market.
Expert Verdict
The pH Plex #3 Stabilizer for Relaxer fills a clear gap in the market: until now, people who regularly use relaxers had no dedicated, patented Plex solution for between-treatment care. With its combination of Malic Acid Complex, antioxidants, and bonding agents, the product delivers scientifically grounded care that works on a molecular level — while being vegan and dermatologically tested. For anyone investing in relaxed hair, this weekly 10-minute routine is one of the most effective ways to secure long-lasting results
