Miracle!!

3 months ago
I received this as a gift with purchase. I was skeptical since I have thin straight hair. I decided to try any way and it is a miracle. I use it on semi dry hair, 1 pump, before using my hot brush. This adds shine and stops frizz even in humidity. Does not weigh my hair down! I’ll repurchase!!

OMG

I am a new Olaplex gal. I have never in my life been more blown away by a hair care line! This stuff is the Holy Grail. I don't know if it's the number nine followed by the number six and seven mixed together in my hands (a little trick I learned from texting with an Olaplex expert) which is another awesome feature that this company offers. But my hair that was NOTICABLY DAMAGED like three weeks ago (I mean I wasn't styling or blowdrying because of how crazy it looked) is now polished, looks fantastic and I am actually happy with my hair. I am seriously in shock of what this stuff does to my hair! I can't say enough good things about this company!!!!!! I DO KNOW THAT I WILL NEVER EVER EVER USE ANYTHING ELSE ON MY HAIR. And that is something that I have never ever said before.

No.9 is the BOMB

9 months ago
A while ago, I chose a small tube of #9 as a free offer when purchasing my routine products and I stored it away. Recently I had to make a short trip & because it was travel size, I brought it along and used it for the first time. OMG. I've loved everything I've tried so far in the Olaplex world, but this was exceptional! It only took a little bit of this clear serum to work through my hair...it rinsed out very clean & easy. But when dry, my hair seemed to have more body...it was smooth & shiny and stayed that way! .I'm absolutely thrilled with this product! Thank you! And one more thing...my carry-on got flagged. A female TSA supervisor happened by as an agent pulled out my bottle of Olaplex shampoo. She said "Oooh, Olaplex! Good choice, good choice...love that stuff!" All I could say was, "Me too!" Thought you'd like to hear that unsolicited comment.

Love ALL Olaplex products!!

I have used No.3 since all the beginning. I like to use a water spray to lightly wet my hair, lavish No. 3 on all over as I have long hair. I tie my long hair into ringlets and leave on until the next day. I take out and spray the ringlets and leave in a second day. It is such an intense treatment that my hair looks like it has never seen a bad day!
