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.

Really nice

I've been using this on my scalp once a week before washing my hair. So far I really like how it feels.

Pretty happy with it

I like the oil and it makes my hair look shinier. Just have to be careful not to apply too much near my roots.

Good but use a little

The first time I definitely used too much lol. Now I just use a few drops and it works great for my dry ends.

Love this oil

I put a little on my ends before bed and my hair feels so soft the next morning. Doesn't leave it greasy either.

I love how lightweight this oil feels. My scalp feels hydrated and my hair looks healthier.

Will keep using it

Wasn't sure about putting oil on my scalp but I actually enjoy using this before shampooing. Easy to wash out too.

My hair needed this

My ends get so dry from bleaching and this has been a nice addition to my routine. A little goes a long way.

Really nice oil and easy to apply. Leaves my hair soft and my scalp feeling moisturized.

Nice shine

I've only been using it for a couple weeks but so far I'm happy with it. My hair feels softer and looks shinier. Just be careful not to use too much.

Good for dry scalp

Definitely helps when my scalp is feeling dry. I personally prefer using it before shampooing instead of leaving it in, but thats just what works for me.

My ends feel sooo good

I originally bought this for my scalp but I've been loving it on my dry ends too. They feel much softer and smoother now.

Surprisingly lightweight

Most hair oils are way too heavy for me. This one absorbs really nicely and gives my hair shine without that oily look.

Part of my weekly routine

I started using this about once a week before washing my hair. Been doing it for a month now and my hair feels softer and just healthier overall.

Really nice oil

I like it a lot and my scalp definitely feels more hydrated. Took me a few tries to figure out the right amount for my fine hair.

A little goes a long way

You really don't need much! I use a tiny amount on my scalp and whatever is left on my ends. Leaves everything feeling super soft.

My scalp loves this

I've been using a few drops a couple times a week and my scalp feels so much more hydrated. My hair looks really shiny too.

Not greasy at all

I was a little nervous about putting oil on my scalp because my roots get oily pretty fast. Surprisingly this feels really light and doesn't leave my hair greasy.

Been using this on my ends too and they feel so much softer. Really happy with it so far.

Makes my scalp feel so much less dry without making my hair super greasy. A little goes a long way.

My hair has been feeling so dry lately and this has helped alot. Doesnt feel heavy at all.

Helped My Dry Scalp

it made my hair feel softer and look shinier.

Perfect treatment

It really helped with frizz and my blonde looks less dull.

My stylist recommended this and it great for colored hair. Super hydrating and gives a beautiful shine!

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.

Try this product and never look back!
