Rosemary Oil For Hair: Benefits & Uses | Holland & Barrett (2023)

Most of us are used to popping a sprig or two of rosemary in our roast dinner, but aside from the cooking connection, it actually happens to be a very versatile herb.

Rosemary essential oil is made from the rosemary (Rosmarinus officinalis)shrub, which is an evergreen and is characterised by its needle-like leaves and woody fragrance.

While these shrubs may be native to the Mediterranean – Tunisia, Morocco and France1- they can be found growing in the UK, Mexico, America and northern Africa.2

So how else can you use rosemary oil in your daily routine? With a lot of online buzz about its alleged benefits for your hair and skin, we dive into the detail in this article.

How is it made?

As with most essential oils, rosemary oil is extracted from the leaves and yellow flowers of rosemary shrubs, using a process widely known as steam distillation.2

How to use rosemary oil for your hair

There’s so much you can do with rosemary oil. From massaging it into your skin to adding it to your shampoo, here’s how to use rosemary oil for your hair:

Rosemary Oil For Hair: Benefits & Uses | Holland & Barrett (1)


Massage it

Dilute 5 drops of rosemary oil with 10ml of Miaroma base oil and gently massage into your scalp, using your fingertips or a scalp massager.4

Either let it soak into your hair for a while or leave it for 5-10 minutes before rinsing it out with warm water.


Mix it

If you like to keep your haircare products natural, you can try adding a few drops of rosemary oil to your shampoo or conditioner, before using it as normal.


Buy it

If you’d rather not mix up your own rosemary oil hair products, thankfully there are a range of shampoos, conditioners and hair masks with the correct amount of rosemary essential oil already in it.

Other ways to use rosemary oil


Apply it

Dilute it with a carrier oil, such as jojoba oil, and then apply it to the soles of your feet or other parts of your body.

(Tip – use 1 drop of rosemary oil per 1 teaspoon of carrier oil for children and 3 to 6 drops of rosemary per 1 teaspoon of carrier oil for adults).


Diffuse it

Put 8 to 10 drops into a diffuser and breathe in the rich herby and earthy-slightly citrusy scent.


Inhale it

Breathe it in directly from the bottle or sprinkle a couple of drops of it on to a cloth or tissue and gently inhale it.


Bathe in it

Run a warm bath and add 4 to 6 drops of rosemary oil. Then relax in the bath for at least 10 minutes to allow the aroma to work.4

How often can you use rosemary oil on your hair?

Since rosemary oil (when used with a carrier oil) is generally considered safe, it can be used daily. But if you find you are experiencing some sensitivity, try using it less or check in with your hairdresser or a medical professional for personalised advice
