Olaplex is one of the most beloved treatments for regenerating hair damaged by lightening, coloring and aggressive styling. But is it really suitable for everyone? Are there contraindications to using Olaplex? In this article we examine possible side effects and offer professional advice based on our direct salon experience.

We are hairdressers across four generations, since 1914, and we put our experience at the service of your hair’s health.

Olaplex is no exception: we use it daily in our professional treatments and know its benefits and possible contraindications in depth.
What Is Olaplex and How Does It Work?
Olaplex is an innovative treatment that repairs hair disulfide bonds — the connections that break due to chemical and mechanical stress (lightening, flat irons, blow drying and aggressive brushing). Thanks to its patented technology, Bis-Aminopropyl Diglycol Dimaleate, Olaplex helps strengthen the hair fiber, preventing breakage and improving hair quality.
The Stages of the Olaplex Treatment
- Olaplex N°1 and N°2 - Professional Treatment: for deep repair, to be used in salon.
- Olaplex N°3 Hair Perfector: at-home maintenance treatment to extend the benefits of the professional service.
- Olaplex N°4 Bond Maintenance Shampoo and Olaplex N°5 Bond Maintenance Conditioner: shampoo and conditioner for continuous care.
- Olaplex N°6 Bond Smoother and Olaplex N°7 Bonding Oil: for styling and heat protection.
Does Olaplex Have Contraindications?
In general, Olaplex is a safe product and well tolerated by most people. However, there are some situations where caution is required.
1. Hair That Is Already Very Healthy and Undamaged
Olaplex is designed for damaged hair. If your hair is already healthy and strong, the treatment may be unnecessary and, in some cases, can make hair appear heavier or less voluminous.
2. Dry or Stiff Hair Effect
Some users report a sensation of dryness after prolonged use. This is not a side effect of the product itself, but rather the result of an imbalance with moisturizing products. Remember: Olaplex repairs, it does not moisturize. That is why we recommend pairing it with a professional nourishing mask to maintain the proper balance.
3. Allergic Reactions or Scalp Sensitivity
Even though it is free from sulfates, parabens and silicones, it may cause reactions in particularly sensitive individuals. A patch test before full application is always recommended.
4. Incorrect Use of the Product
Professional products (N°1 and N°2) require application by experts. Improper at-home use can lead to disappointing or even counterproductive results. For a safe treatment, rely on our professional salon services.
5. Not a Replacement for Other Treatments
Olaplex does not replace nourishing masks or conditioners. If your hair is dry, you still need a complete routine that includes nourishing conditioners and hair oils for optimal hydration.
Our Salon Experience: What We’ve Noticed
In our salon we use Olaplex on different hair types and have found that:
- It performs best on hair damaged by lightening and chemical treatments.
- It is unnecessary on natural, healthy hair, where it can be redundant.
- When combined with moisturizing treatments, it delivers exceptional results.
We test every product before offering it in our e-commerce, and Olaplex has met our quality standards. However, our professional advice is always to trust an experienced hairdresser for more complex treatments.
How to Use Olaplex Correctly
To get the most from the treatment and minimize any unwanted effects:
- ✅ Use it only if necessary: for damaged or chemically treated hair.
- ✅ Pair it with moisturizing products: use a specific moisturizing mask or a reconstructing conditioner.
- ✅ Don’t overdo it: 1–2 times a week is sufficient for maintenance.

Empecé a usar a principios del 2024 y desarrollé una alergia por 1 ańo, fui con dermatóloga por 3 meses luego alergóloga hasta hoy Abril 2025 con diferentes medicinas. Prueba de parches en espalda y me dijeron que no puedo usar los productos. Mi alergia fue horrible, como quemaduras con agua caliente. Uno de sus componentes me produce esta irritación.
