Olaplex No. 4 Bond Maintenance Shampoo, Repairs, Strengthens, & Nourishes All Hair Types, Adds Shine & Leaves Hair Feeling Soft, 250ml

This product does what it says. I’ve used it weekly for a few months now and noticed a real difference in the strength and texture of my hair. It’s smoother, less prone to breakage, and feels healthier overall. You don’t need much per use, so the bottle lasts longer than expected. Works well even on colour-treated or heat-damaged hair. Only downside is the price—it’s on the higher end for the size—but the results justify it.

Lovely oil, my hair has improved so much since using it and my hair would break off all the time, now I am able to grow it long. The bottle is small but I have been using the same bottle for 2 years. You only need 2-3 drops. I wash my hair every 5 days but I use this in between washes too. It’s worked great for me and will always have a stock of it in my house.

Brilliant product really feel the difference in my hair after a couple of uses and styles so much better after drying.

Literally the best hair product out there! Makes my hair so shiny and smooth just wish there was more product.

This does wonders for my hair. Yes it's expensive but well worth it. Love ❤️

Washed my hair and used olaplex bonding oil after my blow dry as can use beforehand. My hair felt so soft ,moisturising to the touch smoothed the hair and soooooo shiny which was a bonus for me as I have greys and menopausal hair...DRY! So using this oil was a treat plus you only need a little as it says on the tin. It says it bonding well I can't comment on that right now..only used once.

Olaplex is one of the best brands out there. A quality brand if you really care about your hair.

It was very expensive but I trusted the reviews anyway, unfortunately haven't seen that much of an effect
