The OUAI Hair Oil offers a range of benefits for various hair types, including Normal, Straight, Wavy, Curly, and Textured hair. This makes it a versatile choice for many users. It is formulated with nourishing ingredients like Ama oil, Baobab seed oil, and galangal root extract, which helps to protect hair from heat damage up to 450°F and UV exposure, prevent color fading, and provide hydration for a shiny finish.

The absence of harmful chemicals like parabens, phthalates, and sulfates is a significant plus for those concerned about clean beauty standards. Its moisturizing properties are commendable, helping to smooth split ends and control frizz, making it suitable for those struggling with hair breakage and dryness. The light scent, Rue St. Honoré, is subtle and pleasant, appealing to those who prefer mild fragrances in their hair care products. The oil's absorption rate is efficient, as it does not leave the hair feeling greasy or weighed down when used as directed.

However, the small liquid volume of 1.5 fluid ounces may not last long for regular users, especially those with longer or thicker hair. Additionally, while it is user-friendly and does not require a professional to achieve results, the price point might be considered high for the quantity provided. The OUAI Hair Oil is a high-quality, multifunctional product that delivers on its promises but may require frequent repurchasing due to its limited volume.

Kerastase Elixir Ultime Refillable Hair Oil is designed for all hair types, making it a versatile choice for managing shine, smoothness, and strength. Its lightweight formula quickly absorbs without weighing hair down, ideal for those who dislike oily or heavy finishes. The presence of Wild Camellia and other nourishing ingredients helps hydrate and protect hair from heat damage, resulting in softer, frizz-free strands with a noticeable shine.

Users can expect up to 10 times smoother and stronger hair compared to non-conditioning shampoo. The scent is a complex blend of mandarin, freesia, cedarwood, and sandalwood, providing a pleasant but not overpowering fragrance. The eco-friendly refillable bottle, made from recycled materials, adds convenience and helps reduce waste. The 75 ml bottle size is modest, so frequent users may need to refill often.

This hair oil offers excellent moisturizing and smoothing benefits and is best applied to mid-lengths and ends rather than roots to avoid greasiness. It is suitable for anyone looking for a nourishing, lightweight treatment that smooths frizz and adds shine with a pleasant scent, especially appealing to those who value eco-conscious packaging.

The Olaplex No. 7 Bonding Oil is a versatile hair oil designed to suit all hair types, including damaged and color-treated hair. One of its major strengths is its ability to significantly increase shine, with a 125% improvement reported compared to bleached hair without the oil. This product also offers impressive frizz control for up to 72 hours, making it a great choice for those in humid environments. Additionally, it provides heat protection up to 450°F/232°C, which is beneficial for individuals who frequently use styling tools.

The oil's formula is free from sulfates, gluten, aluminum, parabens, and formaldehyde, making it suitable for those with sensitivities to these ingredients. It also promises a 77% reduction in hair breakage, helping to strengthen and protect hair for a visibly healthier appearance. The Olaplex No. 7 Bonding Oil is unscented, which can be a plus for those who prefer fragrance-free products. However, some users may miss the sensory experience that a pleasant scent can provide.

The oil is lightweight and absorbs quickly, ensuring that it does not leave a greasy residue, which is a common concern with hair oils. On the downside, the bottle contains only 1 fluid ounce of product, which might not be cost-effective for those with long or thick hair who require more frequent usage. Despite this, the concentrated formula means a little goes a long way. The Olaplex No. 7 Bonding Oil is a high-performing product that offers multiple benefits such as shine enhancement, heat protection, and frizz control, making it a solid choice for anyone looking to improve the health and appearance of their hair.
