Product Information
Full details
The OLAPLEX No.4 Strengthening Shampoo is designed for individuals seeking to repair and restore hair damaged by chemical treatments, heat styling, or environmental stressors. By leveraging patented bond-building technology, this shampoo hydrates and strengthens hair fibers while effectively cleansing away impurities. While it provides professional-grade results and deep moisture, users with extremely fine or oily hair should note that the rich, hydrating formula may feel heavy if used in excess.

FAQs
Is OLAPLEX No.4 safe for daily use?
Yes, No.4 is gentle enough for daily use, although frequency depends on your specific hair type and oil production levels.
Does this shampoo contain sulfates?
No, OLAPLEX No.4 is formulated without sulfates, parabens, or phthalates.
Can I use this if my hair has not been colored?
Absolutely. While it is excellent for colored hair, its bond-building technology benefits all hair types, including those with virgin hair experiencing heat or environmental damage.
Does it provide heat protection?
While the shampoo strengthens hair against future heat damage, it is not a leave-in heat protectant product. We recommend using a dedicated heat protectant spray before styling.
How long does a 250ml bottle typically last?
Due to its concentrated formula, most users find that a single 250ml bottle lasts for 2 to 3 months with regular use.
Troubleshooting
Hair feels weighed down or greasy after washing
You are likely using too much product. Reduce your portion size to a dime-sized amount and ensure you rinse thoroughly for at least 30 seconds.
Difficulty creating a lather
Ensure hair is thoroughly saturated with warm water before application. Because it is sulfate-free, it requires plenty of water to activate the surfactants.

Setup, Compatibility & Care
There is no complex setup required for this product. Simply replace your current daily shampoo with OLAPLEX No.4. It is highly compatible with the entire OLAPLEX range, specifically intended to be used following the No.3 Hair Perfector treatment and followed by the No.5 Bond Maintenance Conditioner for maximum bond-building benefits. To care for the product, keep the bottle stored in a cool, dry place away from direct sunlight to maintain the integrity of the active ingredients. Always ensure the cap is fully snapped shut after each use to prevent water ingress and moisture loss from the bottle.
