It’s no secret that Olaplex has become a highly sought-after brand for products that deliver salon-worthy results from home. Even if you are saving a pretty penny by not booking a trip to the hairdressers, they can still come with a hefty price-tag.
This is why, when we spotted the beloved No.3 Hair Perfector for under £20 on Amazon, we had to check it out. Whether you have chemically treated hair, or you have gone overboard with the heat styling over the years, this hero treatment is what you need.
Usually priced at £28 for a 100ml, you can now bag it for just £19.95, saving 29 percent off the RRP. Garnering over 100,000 reviews on Amazon alone, Olaplex’s No.3 has often been referred to as a “miracle” by beauty buffs whose hair needs a little TLC.

Designed to be used weekly as a pre-wash treatment, it is said to be “the key to your healthiest hair.” Formulated to rebuild all three hair bonds, it has been clinically proven to “reverse hair damage in as little as three minutes”. Results suggest hair is left three times stronger after just one use, meaning you’ll start to see a reduction in frizzy, brittle ends.
Olaplex’s No.3 Hair Perfector has currently amassed a 4.5 rating and more than 97,000 five-star Amazon reviews from a legion of loyal fans who have praised it as “liquid gold” and “nothing short of a miracle.”

One five-star review read: “This stuff is a miracle worker. It is so thick and creamy. Any damage/split ends have started to heal. Been using this for 2 weeks twice a week and hair looks n feels hydrated and so much better.”
A second shopper said: “How did I ever live without Olaplex? I have menopausal, thinning and breaking, ultra fine hair. I have been seriously concerned that I would be bald within 10 years. I have tried EVERY high quality hair product and supplement available on the market. Nothing has worked until I tried Olaplex. It has changed my life. Nothing short of a miracle.”
Another review read: “After just one use this has taken my hair back 10 years in terms of condition and softness. I’ve put my hair through some damage with colours and straightening and my ends were like straw. After using this on my short hair for 15 minutes my hair is considerably softer and shinier. Wish I’d bought this years ago!”
And another devoted fan said: “Olaplex was referred to me by my stylist after years of bleaching my hair and the severe damage and dryness I had. It’s like liquid gold for your hair, it instantly moisturises your hair and it feels like Silk.”
It’s worth noting that many reviews have often criticised the price-tag when not on a deal, with some suggesting the results don’t match the expense. One such three-star review read: “Great product but too expensive for such a small bottle. Did see a difference , but not a lot!”

Adding a bond repair or pre-wash treatment to your hair routine has been recommended by many stylists for shiny, healthy results. This also means that there are many other products now on the market that promise similar results to Olaplex.
