Ideal Usage of OUAI Hair Oil and K18 Molecular Repair Hair Oil

OUAI Hair Oil and K18 Molecular Repair Hair Oil are both high-quality hair care products, but they have distinct characteristics and uses. Firstly, OUAI Hair Oil is a multitasking oil that is ideal for all hair types, especially those with dryness or damage. It is designed to seal split ends, protect hair, and prevent heat and UV damage.

OUAI Hair Oil has a lightweight oil consistency and can be used on wet or dry hair and before & after heat styling. For best results, apply from the eyeline down focusing on mid-shaft and ends. This oil is particularly beneficial for those with color-treated, very damaged hair. It also revives frizzy, crunchy hair while delivering a luxurious, just-out-of-the-salon feel.

On the other hand, K18 Molecular Repair Hair Oil is a biotech-engineered weightless oil that works on all hair types to strengthen, repair damage, reduce frizz at two levels of the hair fiber, and improve shine. It offers clinically proven damage repair, 24-HR frizz control, 104% more shine, 78% reduction in split ends, and 450°F (232°C) heat protection.

To use it, start with 1-3 drops of this weightless formula on damp, towel-dried hair, applying from the mid-lengths to ends. Then you can build as needed without weighing hair down. After styling, you can apply another 1-3 drops to smooth frizz and flyaways, and as a finisher to add shine. This oil is ideal for those seeking to repair hair damage and reduce frizz, and it’s suitable for all hair types. For strengthening benefits from the K18 PEPTIDE, wait 4 minutes before styling.

While both oils offer frizz control and heat protection, OUAI Hair Oil is particularly effective at sealing split ends and providing a shiny finish, making it ideal for those with frizzy hair and split ends. In contrast, K18 Molecular Repair Hair Oil focuses on strengthening and repairing hair damage, making it suitable for those looking to improve the overall health and strength of their hair. Both oils can be used on damp or dry hair, but the K18 oil also offers the flexibility of being used as a finisher after styling for added shine.
