Olaplex No. 7 Bonding Oil, Concentrated High Shine Oil, Heat Protectant, Visibly Smooths & Softens Hair, Added Color Vibrancy, Up to 72 Hour Frizz Control, For All Hair Types, 30ml

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.

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.

Leaves hair smooth, smells great. Very little needed and bottle lasts for months

I’ve always used Redken but it doesn’t seem to make my hair soft anymore. I moved to the UK 2 years ago and the water is extremely hard. I’ve tried numerous products but nothing seemed to work. Not even Redken. This product has been a life changer for my hair. Highly recommend.

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

Wonderful product

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

I bought Olaplex 1 and 2 as a stand alone treatment (my hair dresser also used it on me with a root bleach) and I bought number 3 to use separately alongside my conditioner and moisture treatments. I’ve never regretted buying a product more in my life.I’ve had my hair bleached professionally for 15 years and never experienced more than a few split ends. After my hairdresser used 1 & 2 in my hair it initially felt amazing and looked really shiny. After a few days it started to snap quite a lot. The point of breakage was the part where the newly bleached hair joined the hair that was previously bleached.. the normal area of overlap.I assumed that it was just because the stylist had gone up one level in bleach and I contacted Olaplex and they recommended that I keep using 1 & 2 as a stand alone treatment as well as number 3 regularly.Over about 2 weeks I followed the instructions from the Olaplex rep. I must add that I followed the product instructions exactly and I also conditioned my hair with moisture thoroughly each time I used it to avoid drying.Every time I used the Olaplex product my hair was snapping more and more.. it sounds stupid but it took me over two weeks to work out that the Olaplex was causing this. I sought out independent advice from a high end salon chain locally to me who offer Olaplex as a service. They advised that although the product is amazing for most people, it can have an adverse effect on a fair few people, even with virgin untreated hair.Upon subsequent research I have read about hundreds of people who have had the same experience. It is as though the Olaplex fries your hair and leaves it like snapping burnt straw.Since I stopped using it, my hair has stopped breaking. However I am left with short stubby sections of my hair in various places, mainly on the crown and in the parting. Personally I feel disgusting but I know my hair will grow and I will never use that product again. Using high moisture products since has helped with the overall condition but I can’t get the broken hair back.The product is overpriced and over rated in my opinion. I would strongly recommend doing a test on your hair before using this product all over. If you buy it, test it on a section and wait a week or so to see if it starts snapping.
