FAQs
Hair and Scalp Oil

What does the Repair Hair & Scalp Oil do?
It’s a little bottle of love for both your hair and scalp. This lightweight oil hydrates, smooths frizz, strengthens fragile strands, and helps soothe a dry or tight scalp.

Can I use it on both my hair and scalp?
Yes! It’s designed to care for both. Use a few drops on the scalp for hydration and comfort, or on the lengths to smooth and add shine.

Not at all. The formula is lightweight and absorbs quickly, leaving hair soft, shiny, and smooth—never heavy or oily.

It’s powered by ceramide NG, plant-based superfood extracts (quinoa, chickpea, lentil), and nourishing apricot kernel and argan oils to help strengthen and protect blonde hair.

What results should I expect?
Smoother, softer hair with beautiful shine—and a scalp that feels calm, hydrated, and balanced.

Frequently asked questions

Questions about the Hair and Scalp Oil? Find our most frequently asked questions here. Still need help? Contact us.

What does this oil actually do for my hair?

It hydrates and strengthens hair that feels fragile or damaged, while smoothing away frizz and split ends. At the same time, it works on your scalp to soothe dryness, leaving both your hair and scalp feeling more refreshed and healthy.

Who is this product for?

It's made for all hair types and hair colors. It's especially helpful if you deal with dry or frizzy hair, split ends, or a dry, irritated scalp — common issues regardless of whether your hair is color-treated, natural, curly, or straight.

How do I apply the Hair and Scalp Oil?

You can apply a small amount directly to your scalp to help soothe dryness, and/or work a few drops through the mid-lengths and ends of your hair to smooth frizz and add shine. Since it's a concentrated oil, a little goes a long way — start with a small amount and add more if needed.

Should I apply this oil to wet or dry hair?

Hair oils like this one are generally versatile and can be used on both wet and dry hair, depending on your goal — apply to damp hair before styling to help smooth and protect it, or to dry hair afterward to tame frizz and add shine.

Can this help with a dry or itchy scalp specifically?

Yes — the oil is formulated to soothe a dry scalp, not just condition the hair itself, making it useful for anyone dealing with scalp dryness or irritation in addition to hair concerns like frizz or split ends.

This Repair Hair & Scalp Oil is amazing. My hair feels nourished, smoother, and so much shinier, and my scalp feels calm and balanced too.

— Melanie R.

The Science

A synergistic blend of skincare actives and superfoods

Squalane

A must-have skincare active for hydration, squalane is a biomimetic, mimicking the scalp’s natural sebum to rehydrate the hair and condition coloured strands from the inside out.

Açai Extract

A superfood rich in polyphenols and omegas, açai fruit smooths the cuticle and enhances elasticity to fight the frizz lightening can cause, protecting blondes from brittle strands.

Moringa Oil

Rich in antioxidants and oleic acid, moringa oil strengthens blonde hair against the everyday stressors that cause colour fading and brassiness. Because blonde hair shouldn’t be fragile hair.

Argan Oil

Known as ‘liquid gold,’ argan oil is rich in linoleic acid and vitamin E, replenishing the fatty acids and moisture stripped by bleach and colour to make blonde hair softer, shinier, golden.

I was given a sample of this a year or so ago. It was time to purchase more. The price was good and it lasts forever. I have very thick curly frizzy hair. The humidity makes it huge. Well, this product helps maintain my hair. It reduces the Celtic hair to a more manageable style. Good luck and enjoy not looking like a hairy beast

I am very picky about hair oils. My hair is dry and thick, so I like the hydration they provide, however cheap oils weigh my hair down and make it oily very quickly. This hair oil is super hydrating and never leaves an oily feeling after it is absorbed in the hair. I use it out of the shower and as a heat protectant. The bottle was slightly leaking in the box when it arrived, but very little product was missing and the bottle itself seemed okay so I decided to keep it.

I use this along with the Oligo 18 benefits spray for extra shine.
