Beauty Files | Bye Bye, Brassy

Happy Monday, friends! I hope you had a wonderful weekend, that was equal parts productive and relaxing. We had the most glorious weather yesterday, so we spent most of the day outside. It’s amazing what sunshine can do for your mood and outlook!

Today we’re talking beauty, and it’s a post that’s been highly requested. It’s no secret I’ve been on the Olaplex fan train since I’ve been talking about it on repeat for over a year… in fact, I credit it with repairing my broken hair and restoring shine and strength.

I started with the No. 3 Hair Perfector and was so immediately blown away by the difference, I began introducing new Olaplex products one at a time. It wasn’t long before my entire hair routine was made up of Olaplex products. After all, considering what I spend to get my hair cut and colored, investing in the care and maintenance is worth it!

They recently launched the brand new Olaplex No. 4P Blonde Enhancer Toning Shampoo, and I couldn’t order it fast enough! And based on the number of questions I’ve received about it, many of you are excited to try it out, too!

This purple shampoo cleanses, tones, and repairs while keeping hair hydrated from roots to ends. I’ve tried a slew of purple shampoos over the years, and none compare in both potency and hair health to the Olaplex No. 4P Blonde Enhancer Toning Shampoo.

This highly concentrated, sulfate-free shampoo forms a rich lather to neutralize brassiness and boost brightness after one use. Suited for all blonde, lightened and grey hair, the non-drying formula can be rotated into any hair maintenance routine as needed for no more brassy!

Many potent purple shampoos leave my hair feeling dry and stripped, but this one actually leaves it feeling soft. For me, it only takes a minute for it to tone down my brassiness, so I rinse as soon I reach full lather.

If it’s been a few days between shampoos, I first wash with Olaplex No. 4 Bond Maintenance Shampoo for a good cleaning, then a quick wash with the No. 4P Blonde Enhancer Toning Shampoo. And I always follow with the Olaplex No. 5 Bond Maintenance Conditioner.

This is one of the most potent purple shampoos I’ve tried, so I’d recommend letting it process in short increments until you find the sweet spot for your hair! I use it about every 10 days, or when I notice my hair is getting too ‘yellow.’ The results are immediate and gives my color a fresh boost.

Each of the Olaplex products is highly effective on their own, so it’s not essential to use the entire line to see improvement, but I can almost guarantee you’ll be so impressed by the transformation of your hair, you won’t want to use anything else!

If you’re looking to start small, definitely go with Olaplex No. 3 Hair Perfector first, followed by No. 6 Bond Smoother! My hairdresser is amazed each time I come in at the transformation of my hair! It’s stronger and shinier, with noticeably less damage and breakage.

So tell me, are you on the Olaplex train with me? Have you tried the No. 4P yet? Oh, and if you’re wondering, Nos. 1 and 2 are for use just in salons!

    Do you use this with your extensions in? I’m scared to use my purple shampoos with extensions.

      Yes! I don’t remove my extensions, only my hairdresser does to move them up once my hair grows out! xo, C

        What kind of extensions do you use as I had them but once I started using Olaplex they started falling out…

          I have a few tape-in extensions on the sides of my head for fullness and a little more length. The only product I apply to my scalp is the No 4 shampoo and No 4P shampoo…the rest I concentrate on the mid-shaft to the ends. I’ve not had any issues with my extensions staying in. I do use a detangling brush and go gentle when combing my roots so not to pull or snag them, and keep anything with oils away from the tape part.

      Yes ma’am…just a few tape-in pieces on the sides for fullness and a little length. I don’t wear them year-round, but do have them in now. My hair has slowly gotten thinner as I’ve aged, and they make such a difference!

      Hi Noa! Olaplex 3 isn’t actually a protein, but based on my research, hair that’s overly elastic is in need of a protein treatment. I’d ask your stylist! xo. C

    I’m excited to try the purple olaplex as I use their other products ( 4, 5 and 3 and the oil number 7) and I get blonde highlights. I was using the shampoo and conditioner too often though and my hair was getting brittle due to too much protein in their products.. My hair stylist checked with her rep and she said it’s a great product but not to use daily as it contains too much protein and will cause brittle and breakage! I have started using it once a week to every two weeks and use Moroccan products in between! My hair has never been so healthy! I was just over using the Olaplex products when it came to the shampoo and conditioner!
    Thanks for sharing this latest addition to the line:)

      Absolutely, Karen! I don’t shampoo and condition every day, so I haven’t been having that protein problem, but good to note!! xo, C

  6. I tried the purple Olaplex for the first time yesterday and had a struggle getting it to lather like the regular shampoo. Did you have the same experience? I ended up mixing in a little of the regular shampoo, but not sure that’s the best thing to do.

      I always wash my hair with the regular shampoo first, to get it good and clean. Then the second wash is with the 4p…it lathers a lot better when my hair is clean. But mixing with the reg shampoo is totally okay, too!
