Who Should Buy This
This Olaplex Nº.5 Leave-In Conditioner is perfect for anyone looking to repair and protect their hair. It works well for all hair types, including coily, curly, straight, and wavy hair. If you have dry, damaged, or split ends, this product helps moisturize and mend your hair. It also reduces breakage, making your hair stronger and healthier. Plus, it is a great choice for those who want a lightweight conditioner that does not weigh hair down. The 100 mL size is ideal for travel or as a thoughtful stocking stuffer gift.
People with very oily hair or those who prefer heavy, creamy conditioners might want to avoid this product. It is designed to be light and nourishing, so it may not provide enough moisture for extremely dry or coarse hair without additional products. If you are allergic to any ingredients in the formula, it is best to skip this conditioner to avoid irritation.

Our Testing Experience
First Impressions
When I first tried the Olaplex Nº.5 Leave-In Conditioner, I was curious about how it would feel on my hair. The cream has a velvety texture that spread easily without feeling heavy. I applied a small amount to damp hair after washing and immediately noticed it didn’t weigh my hair down. The scent was light and pleasant, which made the whole experience enjoyable. I was excited to see if it would actually help with my frizz and split ends.
Daily Use
Using it daily became a part of my hair care routine quickly. Each morning, I applied the leave-in to damp hair and either air-dried or blow-dried it. I was happy to see my hair felt softer and smoother throughout the day. The best part was how it tamed my frizz, even on humid days, which usually make my hair wild and hard to manage. My hair looked healthier and felt more manageable without any greasy or sticky residue.
Key Features in Action
The heat protection up to 450°F was a big plus for me since I often use a blow dryer and flat iron. Knowing my hair was shielded from damage gave me peace of mind. The claim of 72-hour frizz control really stood out. I noticed less frizz and more defined waves when I air-dried my hair, which made styling easier. Also, the product helped reduce breakage – my hair felt stronger and I had fewer knots while brushing, which was a noticeable improvement.
Long-Term Performance
After using Olaplex Nº.5 for several weeks, I saw real changes. My split ends looked better, and my hair felt more resilient overall. The softness lasted even on the days I didn’t wash my hair, and my usual dry spots were much less noticeable. I appreciated that it worked well on my naturally wavy hair, but I think it would be great for any hair type. Overall, it became a staple in my hair care because it truly moisturized, repaired, and protected my hair over time.
