Introduction to OUAI Hair Oil and Leave In Conditioner
Founded by celebrity hairstylist Jen Atkin, OUAI is an American lifestyle brand offering a wide range of beauty and haircare essentials. Their products cater to various hair textures and types, from shampoos and conditioners to styling aids like oils and pomades.
OUAI Hair Oil is a multitasking treatment designed to tame frizz, seal split ends, and deliver a healthy, glossy finish. It protects hair from heat and UV damage while enhancing color longevity, thanks to a thoughtfully curated blend of nourishing ingredients.
Meanwhile, OUAI Leave In Conditioner is a frizz-fighting, thermal-protective spray that repairs dry ends, guards against breakage, and adds slip for easy detangling. It doubles as a pre-heat styling primer or a go-to product for wash-and-go routines, offering protection from heat up to 450°F (232°C).
While both products provide heat defense and frizz control, their unique benefits cater to different haircare needs. Let’s explore them in detail.

This product is also vegan, cruelty-free, and free from gluten, parabens, phthalates, and sulfates.
Texture and Scent
Ouai Hair Oil
With its lightweight and non-greasy formula, this oil suits all hair types—including fine hair. It absorbs quickly, leaving no residue. The fragrance is a refined floral blend featuring violet, gardenia, ylang-ylang, and white musk, offering a fresh, feminine scent loved by many users.
OUAI Leave In Conditioner
This product is a spray with a slightly creamy, lotion-like consistency rather than a fine mist. Despite this, it doesn’t weigh hair down and excels at detangling. Users report their hair feels softer and smoother after application. The scent, known as North Bondi, combines fresh floral notes with bergamot, violet, and white musk for a luxe, salon-fresh aroma that lingers subtly throughout the day.
How to Use OUAI Hair Oil and Leave In Conditioner
Ouai Hair Oil
Ideal for all hair types, especially dry or damaged strands, this multitasking oil seals split ends and shields hair from heat and UV damage. Apply a lightweight amount on wet or dry hair, focusing from mid-length to ends, before or after heat styling. It’s particularly beneficial for color-treated and frizzy hair, delivering a salon-quality shine and softness.
OUAI Leave In Conditioner
This versatile detangler spray hydrates, smooths, and fights frizz while protecting against breakage and heat damage. Suitable for all hair types, it works well on thicker, coarser, or curly hair needing extra moisture and flyaway control. Apply to towel-dried hair from about 6-8 inches away, avoiding roots, then comb through to distribute evenly. Use as a pre-heat primer or in your daily wash-and-go routine.
Both products can be combined in your haircare regimen—start with the hair oil to seal and protect, followed by the leave-in conditioner for detangling and smoothing.
Price Comparison
OUAI Hair Oil typically costs between $15-$18 for a 15ml travel size and around $30 for the 45ml full size. On the other hand, OUAI Leave In Conditioner is priced approximately at $17 for 45ml and $30 for 140ml. Per milliliter, the hair oil is somewhat pricier, reflecting its concentrated formula and multitasking benefits.

- Choose OUAI Hair Oil if your priority is reviving damaged strands, taming frizz, and achieving a glossy finish. Its lightweight formula provides split end protection and heat defense suitable for all hair types.
