10 Best Hair Oils 2025 in the UK

Nature Spell Rosemary Oil is positioned as a versatile product for both hair and skin, with claims of stimulating hair growth, strengthening hair, and reducing hair loss and greying. It suits all hair types, which is beneficial for a broad audience. The oil's rosemary scent is pleasant, and its natural ingredients suggest it’s a safer option, especially since it's free from parabens and cruelty-free. The absorption rate is an important aspect, and rosemary oil is known for being relatively lightweight, meaning it doesn’t leave an overly greasy residue, which is a plus for daily use.

Users aiming to combat hair thinning might find this product particularly useful due to its resemblance to minoxidil effects, commonly used for hair loss treatment. Additionally, its application to the skin can enhance complexion and reduce under-eye puffiness, thanks to its antibacterial and circulation-boosting properties. However, while it advertises benefits for itchy scalps, individuals with sensitive skin should test the product first, as essential oils can sometimes lead to irritation.

The oil is in a convenient 150 ml bottle, which is an adequate size for regular usage. It's worth noting that while the product ranks high in customer reviews, personal results can vary, particularly in terms of hair growth and anti-aging claims. For those seeking a natural remedy to improve hair and skin health, Nature Spell Rosemary Oil could be a worthwhile consideration, keeping in mind the importance of consistent use for best results.

The Moroccanoil Treatment Original is a popular hair oil designed to benefit various hair types. Its key ingredient, argan oil, is known for its nourishing properties, and the inclusion of vitamins enhances its ability to hydrate and soften hair. It's particularly useful for detangling and smoothing frizz and flyaways, which can improve the appearance of your hair by up to 118%, according to the manufacturer. The product is also free from harmful chemicals like sulphates and parabens, making it a healthier choice for your hair care routine. With a light, pleasant fragrance, it’s likely to appeal to users who prefer a subtle scent in their hair products.

The oil comes in a 100 ml bottle, which is a convenient size for regular use and travel. However, for those with oily hair or those preferring a lighter formula, the absorption rate might be a concern, as some users report it can leave hair feeling greasy if over-applied. Additionally, while it’s touted as suitable for all hair types, individuals with fine hair may want to use it sparingly to avoid weighing their hair down.

The product has been available since 2009 and continues to be a bestseller, suggesting strong customer satisfaction. It is manufactured in Israel and has not been discontinued, indicating its sustained popularity in the market.

The OGX Argan Oil of Morocco Extra Penetrating Hair Oil is designed for those with dry and damaged hair, although it claims suitability for all hair types. It shines in its role to provide intense hydration and reduce frizz, thanks to the infusion of high-quality Moroccan Argan Oil. Known for its nourishing properties, the oil deeply penetrates the hair shaft, which may help in reducing breakage and split ends. This makes it a potentially great fit for individuals needing extra care, especially those dealing with color-treated or heavily styled hair.

One of the standout features is its ability to be used in multiple ways, such as a daily leave-in treatment or an overnight mask, offering flexibility in hair care routines. The absorption rate is optimized by applying it to wet, towel-dried hair, which suggests effective deep conditioning. Additionally, its pleasant Argan Oil scent adds to the sensory experience, making it enjoyable to use.

However, for those with fine or oily hair, the oil might be too heavy and could weigh down the hair if used excessively. Being an oil, it might not be suitable for everyone depending on their preference for hair care products that feel lighter or less oily. The 100 ml bottle is a decent size, but usage frequency and hair length could affect how long it lasts for each user.

This product is well-suited for individuals seeking to improve the texture and manageability of dry or damaged hair, offering both protection and shine. Potential buyers with different hair types should consider how this oil fits into their existing hair care routine.
