Shop Hair Oils and Serums at Holland & Barrett

Your hair goes through a lot, from regular washing to heat styling and breakage, so treat your tresses to some TLC.

The perfect pairing to your shampoo, conditioner or hair mask, hair oils and serums provide your locks with essential ingredients to help fight frizz, dehydration and dead ends. Infused with nourishing ingredients like rosemary, argan, and coconut oil, our hair oils and serums will transform dull, tired hair into vibrant and healthy.

Say goodbye to dry ends with a nourishing hair oil

Treating your hair from root to tip, hair oils are like a drink of water. These oils nourish your hair from within, providing essential nutrients and moisture to your scalp and ends. Hair oils penetrate the hair shaft, creating a protective barrier to help tame frizz, flyaways and dehydration. Plus, they add a lustrous shine, making your hair look healthier and more vibrant. Regularly using hair oil can help repair split ends, prevent breakage and some are thought to even promote hair growth.

Tame your tresses with a hair oil serum

Lighter than an oil, hair serums are styling superheroes packed with hair-loving ingredients. Perfect for curly, dry or even dyed hair, a few drops will smooth frizz, boost shine and enhance your hair's natural beauty.

Don’t forget your scalp

A healthy scalp is the foundation for strong, beautiful hair. Keep your scalp happy, hydrated, and nourished with our scalp oils and serums. Massage in for increased blood flow and to remove product buildup.

Why Choose Castor Oil for Your Hair?

Castor oil is well-known for its deeply nourishing properties, making it ideal for those dealing with dry, damaged hair or looking to support hair growth. Our castor oils are rich in essential fatty acids and vitamin E, hydrating your hair from root to tip and locking in moisture. With regular use, castor oil can help reduce split ends, prevent breakage, and even promote a thicker appearance for your locks.

Nourish and Protect with Jojoba Oil

Lighter than castor oil, jojoba oil is a versatile choice suitable for all hair types. Known for its ability to mimic the scalp’s natural oils, jojoba oil delivers hydration without weighing hair down. Try our jojoba oil for a smooth, silky finish that reduces frizz and enhances shine. Whether you’re dealing with dry ends or just need a boost, jojoba oil is a go-to for creating lasting moisture and a balanced scalp.

Shop hair oils and serums at Holland & Barrett

Whether you're battling frizz, craving shine, or aiming for hair growth, we have the perfect product for you. Our gentle formulas suit all hair types, including colour-treated hair. Before using a new hair product, make sure to do a patch test first to check it is safe for you to use.
