OLAPLEX started in 2014 in a California garage, where Dean Christal worked with chemists Dr. Eric Pressly and Dr. Craig Hawker on one patented ingredient that relinks broken bonds inside hair. It began in salons, created the bond-building category, then moved home with its numbered system.

Editorial
Bond building systems went from a salon secret to a mainstream shelf, led by Olaplex and K18. I go through the names that made it mainstream, then masks for deeper repair and serums.

Editorial
Olaplex No.3 now lives on as No.3PLUS, and the brand has built a whole numbered system around it. Here are masks, shampoos, conditioners and leave-ins, and how I would use each one.

Editorial
Olaplex has a numbering system that confuses almost everyone at first, so this edit sorts it out. You will find the treatments, oils and creams, the No.4 and No.5 wash-day line including Olaplex shampoo, and a few other bond builders people ask about.

Editorial
Olaplex Bonding Oil is the brand's lightweight, heat-protecting finishing oil, and like every Olaplex product it carries the patented bond building ingredient. Here it is with the other leave-ins, the numbered repair steps and four other hair oils I compare it with.

Editorial
The best leave in conditioner for a blowout depends on your hair: a weightless detangling spray, a richer curl cream or a frizz milk. I compare OLAPLEX No.5L, Moroccanoil, Briogeo and more.

Editorial
The best shampoo for dry frizzy hair starts at the cuticle, not at the ends, since a raised and dry cuticle is what lets frizz in. For years the instinct was to add more product on top, when the real fix is cleaning gently enough that the cuticle never gets that dry in the first place. This edit sorts a range of formulas by texture and by what actually causes the frizz they are meant to fix, from occasional buildup to real strand damage to drier, aging hair.

Editorial
Hair oil in two kinds, finishing oils for lengths and ends and pre-wash oils for the scalp.

Editorial
A shampoo that doesn't weigh hair down cleans the scalp without leaving waves flat, and a weekly clarifying wash keeps them bouncy. I went through lightweight and volumizing shampoos, light conditioners and styling that brings the wave back.

Editorial
TYMO came out of China in 2019 and reached the U.S. with a straightening brush built for coarser hair. Here are its brushes and combs, the curlers and wavers that came after, and the heat sprays I would put down before any of them.

Editorial
Olaplex can be worth it for chemically treated or heat-stressed hair that feels fragile, but it is not a cure-all for every texture concern. I weigh the bond-building claim against independent reviews, return policies, and targeted full-size options.

Editorial
Rosemary hair oil went from a folk remedy to a bathroom-shelf habit, helped along by a 2015 study and a lot of TikTok. Here are the rosemary oils, serums and scalp sprays, plus the rosemary shampoos and conditioners to use alongside them.

Editorial
Biolage launched in 1990 as a salon brand built on the idea that a shampoo can feel like a spa visit. Here is how I would pick between Hydra Source, Strength Recovery, Color Last and the rest, plus the masks, leave-ins, other salon conditioners and scalp treatments that sit beside them.
