Yas yas yas!!! Where has this treatment been all my life?!?! After years of hellish bleaching to achieve and maintain my LittleMermaid red hair, I was finally ready to give up until.....the day we met. You saved me No.3. You saved my hair. I will forever be grateful. I use every time I wash (only once MAYBE twice a week) usually apply BEFORE and after I shampoo. The second round is usually a pea sized amount (past shoulder length hair) that I do not rise out. I have no issues with oiliness leaving this product in. Since using this process religiously for the last 8 months my hair has been completely healed. My stylist is jealous now #win

we sell this as a take home product at my salon, and as soon as we get it in..it's gone. Yes, the number 3 bottle is little, HOWEVER...
you apply it to WET towel dried unwashed(not shampooed) hair(aka make sure you get all the water out of your hair so it's basically just wet/damp), the product glides through the hair wet really nicely ,and you can take a widetooth comb to comb it through, once. You wanna leave this in for a minimum of 10 minutes..  This is a great product, if you have hair damage it helps, and it helps in between chemical services. I really love this, and so do my clients.

My old salon started using this system years ago and got me hooked! I am naturally blonde, but add highlights and lowlights for dimension every 10 weeks or so. This product helps to prevent breakage like none other. If you are lightening your hair, this is a must have product. My stylist provides this as a take home treatment to use weekly between colorings. If you can find a salon that uses it, definitely give it a try.

This is like hair magic. It's the only take home part of the Olaplex 3 part system.
It literally rebuilds the bonds that are broken during bleaching, coloring, chemical services & heat styling.
I'm pretty sure without Olaplex Hair Perfector No. 3 I'd be baldish right now, I've bleached 3 times this summer. Toned & colored & bleached again.
I got my hands on some of this & used once weekly has been a godsend.
Hair is healthier, lighter, bouncier.
Cannot recommend this & the whole Olaplex Salon into Kit for Professional Use enough.

Olaplex SAVES your hair!! I will NOT go without this product while bleaching or coloring my hair. It provides so much moisture and products your hair from any breakage. It smells so good too. It’s worth every penny, you can definitely tell if you didn’t use this, after finishing your hair. There really is no comparison to this product. It’s a must have. Olaplex Hair Perfector No. 3

Used on a client that had extreme damage from an at home relaxer, and was also severely over processed. Hair shafts were literally breaking just being wet. Used this and left it on for 40 minutes, rinsed it out, shampooed, and did a conditioning treatment and her hair was more than 50% repaired. She was so immensely happy she already rebooked for every 3 weeks until it's fully repaired.

10/10 LOVE OLAPLEX. I have dyed my hair just about every color in the rainbow and have bleached my hair countless times. I also used to have horribly chlorine-damaged hair which would tangle like no other. My hairdresser introduced me to this product when she went from dying my dark brown hair that had been dyed on top of blue dye (so it was a bit green) and went blonde. She bleached my hair 2-3 times that day alone, but I swear only like 1 strand of my hair fell out. This is a miracle product that I can't live without. I use this in my hair every 2 weeks or so, and I let it sit for hours typically. It's a bit pricey, but I feel like the value is there. I've purchased this item probably 10 times by now and absolutely plan on purchasing it again.

As a runner, whose hair is a ponytail daily, this stuff is awesome. I have experienced breakage from wearing my hair in a ponytail so much, and someone at my gym recommended Olaplex. I use it once a week. It smells lovely, is easy to use and it does seem to be preventing future damage, and helping to grow out the pieces that have been damaged. Pro tip - if you’re a runner, put this on before your weekly long run and let it work for an hour or two, or three while you run. Then go home and wash it out. Works fantastically!

If you have very processed or brittle hair that needs some extra love, oleplex is for you. I cannot even begin to write how much I adore oleplex. I use it once a week, and it says to leave in for 20 minutes to an hour, but I usually do it before bed and just sleep with it in. You don’t notice it right away, but within about 4 uses you really start noticing your hair feeling stronger, shinier, better than it’s ever felt before. There is something in it that works as a bonder, and literally bonds your damaged ends back together. If you’re having any concerns with hair being brittle, dry, breaking, over processed, oleplex is your answer.

The most amazing treatment for your hair. It’s not actually a conditioning treatment, it’s a bond builder. I put it in my hair and clean my whole house, do laundry, cook and then I wash it out. The longer I leave it in the better it works I feel. Nothing has saved my hair more than Olaplex Number 3.

I paid extra for the olaplex treatment when I initially dyed my hair and then ordered the third step online to use intermittently. I thought I noticed a big difference with the treatment from the salon but I don't notice any kind of smoothness or healthiness after using step three on my own. Is it meant to be used on its own?

Do you use conditioner on your hair daily, once a week , or few times a month. I really dislike conditioner daily. I feel like I lose hair. I condition 2x a month , ends only. Olaplex Hair Perfector No. 3 is amazing for color treated hair. What do you use ? And how often?

IS this product worth the cost? My stylist is charging $40 for an olaplex treatment, but isn't giving my the third step in-home treatment. That means I've got to pay for in addition to the salon service. Should I get it?

What is the best way to use this? I've bleached my hair to go blonde a few times, my hair is pretty dry but gets oily at the roots. Is it better to leave it in overnight with a cap on or let it sit for a few hours? Not sure what is the best route for the best results.

I've read excellent reviews about this product. How long does it usually last? It's a big investment!
