I have naturally wavy hair that’s usually super dry and frizzy. Not with this product. If I use it and let my hair air dry the waves look luscious. If I blow dry my hair straight it just adds beautiful shine. Highly recommend. 

This is my favorite hairserum and I've tried quite a few. I have damaged overprocessed hair and my hair needs all the help it can get. Olaplex helps greatly with that need. This serum helpt protect my hair against heat and makes my hair feel soft.

Olaplex No. 9 has become my latest obsession in the Olaplex lineup, and I can confidently say it's a game-changer for my dry, fine hair. This dreamy hair serum has earned its permanent spot in my beauty routine, and I plan on sticking with it till the very end. No. 9 nourish and hydrate without weighing down my fine strands. The serum feels luxurious and absorbs quickly, leaving no greasy residue behind. It's like giving my hair a sip of much-needed hydration, and the effects are both instant and long-lasting. I've adopted a trio of Olaplex products, combining No. 3, No. 9, and No. 7, and the results are nothing short of spectacular. This powerful trio has transformed my hair into a mane that looks like it just received a professional salon treatment. The synergy between these products is truly magical.

A perfect product, I really liked it and will definitely order again!!

I really love it, it keeps the hair shiny
