"My first pick in the splurge category is the Olaplex No.4 Bond Maintenance Shampoo. This one hydrates beautifully and softens without weighing your hair down. Their key ingredient is this long molecule bis aminopropyl diglycol daliate, which is their patented bond repair technology. It also has panthenol, which I've been loving recently for skin barrier repair, so it helps with repair of your scalp skin barrier. Glycerin is a great humectant, helping your scalp hold on to moisture. I also really just truly love the way it smells, and it makes my hair feel less damaged after I use this Olaplex shampoo."

"In 2018 they launched their number three hair perfector number four bond maintenance shampoo and number five bond maintenance conditioner this finally allowed fans of the brand to get the bond building effects of Olaplex without having to go to a salon. When I worked in a salon we were an Olaplex salon we actually would not bleach hair or touch damaged hair without using Olaplex it became a must-have because of how effective these in salon versions were people loved it they were buying it out of the salon."
