Unnecessary Product

3 stars out of a maximum of 5

I tried all of the Olaplex products and love No. 6 & 7. Use No. 6 in wet hair and No. 7 after blow drying for extra shine. Perfect! I feel like this is a bit redundant. I will use it up but won't buy again.

Olaplex's new hair serum saved my hair

5 stars out of a maximum of 5

The smoothness. Not only does the serum repair hair, but also protects it, so damage doesn't happen in the first place. It has nice smell and texture. My hair loved it. Already on my second bottle of it.

Good for glossy finish

4 stars out of a maximum of 5

The new addition number 9 works well for me as a finish and final step in my routine. I’ve not noticed improvement to my hair in the long run with this product, however it gives a nice glossy finish after styling or curling my hair and works better than an oil for me.

For heat protection from a trusted brand

5 stars out of a maximum of 5

I’m a huge fan of Olaplex, a brand that has made a huge difference to my hair. I will do a full Olaplex treatment routine (0, 3,4 and 5) almost every week and I also use No. 6 and 7 regularly for styling. I like Olaplex 9 because of the heat protection (the oil has heat protection, but I don’t think a few drops will provide adequate protection for proper heat styling). I use No.9 as the first styling step in my haircare routine, as a heat protectant. I don’t feel like I get many additional benefits from this product especially because I’m already using other Olapex products, but it does improve shine and smoothness if I use it with other non-Olaplex shampoos and conditioners. Since I always use a heat protectant before heat styling, I will continue to purchase because I trust this brand.

So Disappointed

1 stars out of a maximum of 5

For years I have heard such good things about Olaplex and after reading great reviews for this product I thought I would splash out and try it. I was so looking forward to using it but was left bitterly disappointed by it. The first time I used it my hair felt sticky and frizzy so although I used it sparingly l figured I’d used too much. The next time I washed my hair using my detox shampoo to remove the product and start again and put a tiny amount on the ends and worked a little up to mid length. It didn’t feel as bad but my hair still felt sticky and dry. I’ve watched videos and read reviews to see if I’m doing something wrong but it still does absolutely nothing for my hair except make it feel horrible. A complete waste of money for me I’m afraid.
