Olaplex has become one of the most discussed hair care brands on the market. With their patented technology, sustainable practices and versatile products, it's understandable why TikTok "For You" pages are filled with reviews. But what exactly makes Olaplex so great?

What is in Olaplex?

The brand puts science and innovative technology first. Hair strands are made up of millions of disulfide bonds, and when the bonds are broken, it results in damaged hair strands. These bonds are typically broken during heat styling, bleach or coloring process. According to Olaplex's site, they use a patented ingredient: Bis-Aminopropyl Diglycol Dimaleate. The sometimes hard to pronounce item repairs the hair from the inside out. Its ability to align the bonds in the hair results in the appearance in healthy, strong and shiny mane. The patented ingredient can be found in every product, including the oil.

What hair type works best with Olaplex?

The innovative technology is designed to work for all hair types — and targets damage created by heat styling, hair color and damage caused by UV rays. The range of shampoo, conditoner, oil and repair products work for straight, curly, fine and thick textures. Regardless of the texture, all hair is made up of bonds, making Olaplex one of the most diverse brands within the beauty industry.

What do the numbers on Olaplex bottles mean?

Each bottle has a number, which signifies the order it goes in your routine. However, number one and number two are only for professional usage and cannot be bought by a non-cosmetologist. The products range from zero to nine and typically include recommendations on how to combine products or cocktail them. Ultimately, the numbered bottles make it easy to incorporate into any wash day routine without any confusion.
