Less breakage. Fuller lengths.

Protects

The JUVA Pre-Wash Hair Oil helps protect your lengths before they even get wet.

It coats and lubricates the hair fibre, helping reduce the swelling, dryness and friction that can make wash day stressful for fragile lengths. It also creates a protective buffer between your hair and the minerals and impurities in your water.

Less friction. Less unnecessary breakage. More of your length stays intact.
Elasticizes

Dry, weathered hair is more rigid and more prone to breakage.

The JUVA Pre-Wash Hair Oil conditions and lubricates the hair fibre, helping lengths stay softer and more flexible so they can bend and move with less resistance during washing, brushing and styling.

More flexibility means less unnecessary breakage and more of your length stays intact.
Conditions

Your ends are the oldest part of your hair and have been exposed to years of washing, heat and friction.

The JUVA Pre-Wash Hair Oil replenishes softness and smooths these weathered lengths, helping reduce roughness and improve shine.

The result: softer, smoother ends that look fuller, healthier and less dry or wispy.

what consistency looks like

  1. first use

    Instant softness & shine

    Lengths feel silky, smooth and noticeably softer, without the heavy, greasy finish. A nourishment boost for very dry or damaged ends.

  2. weeks 1–2

    Less breakage. Smoother wash days.

    With consistent pre-wash oiling, your lengths start to behave less porous, so they hold on to more hydration and feel more conditioned. Customers report less breakage during washing and smoother styling afterwards.

  3. weeks 4–6

    The healthy-hair glow builds

    More visible shine, softer texture and ends that feel stronger, smoother and better cared for wash after wash.

  4. week 12+

    More of your length stays with you

    Consistent protection helps prevent the breakage and split ends that keep hair stuck at the same length and leave ends looking thin. It supports fuller-looking ends and better length retention over time.

the science behind it

  1. oil penetration + fibre fatigue strength

    Marsh et al., International Journal of Cosmetic Science, 2024. triglycerides and plant oils penetrated the hair fibre; the tested oils improved single-fibre fatigue strength.

  2. hair friction + porosity

    Weiand et al., Advances in Colloid and Interface Science, 2025. weathering raises the friction of hair; conditioning deposits on the surface bring it down.

  3. coconut oil + protein loss

    Rele & Mohile, Journal of Cosmetic Science, 2003. coconut oil reduced protein loss in damaged and undamaged hair. background on coconut oil itself, not a test of this formula.

How to use

Repeat before every washday or 1-2x per week for best results.
Apply

Apply treatment generously (2-8 pumps depending on length & thickness) on dry hair from mid-lengths to ends.

Leave on for at least 1 hour, or overnight for a deeper treatment. Use the hot booster cap for a deeper and faster treatment.
Shampoo

this easy-rinse formula washes out cleanly. shampoo the scalp thoroughly, twice.

Tip: Don't scrub your lengths. These get rinsed naturally by the shampoo flowing down from your scalp. This helps prevent dryness.
Condition

follow with conditioner on lengths to loosen any residual oils and seal the cuticle.

pre-wash treatment

deep treat before wash day

made for your lengths

formulated to nourish and protect dry, damaged lengths, the part most prone to breakage.

conditions beyond the surface

triglyceride-rich oils like coconut are shown in studies to penetrate the hair and reduce protein loss.

clean rinse

absorbed by the hair, and after shampoo it doesn't feel heavy.

a scent everyone falls for

a subtle touch of natural perfume makes it a routine you'll want to repeat.

regular hair oils

finishing oil

made to sit on top of styled hair for shine.

one oil for scalp + hair

essential oils can dry out your lengths while oils for the lengths grease your scalp.

mostly coats the surface

silicones and thick oils add slip and shine, but don't penetrate the hair to nourish it.

can build up or feel heavy

which can leave hair looking dull over time.

commonly too strong

heavily fragranced or smelling strongly of the base oils.

faq
how does this treatment help hair length?

It's likely that your hair is just breaking before you notice the length.

Breakage happens along the hair strand, not at the root. 

Oiling the lengths helps keep hair elastic and conditioned, reducing breakage. 

When fewer strands snap, more reach their full length, making hair look thicker, longer, and healthier.
is it like a scalp oil or finishing oil?

- NOT a finishing oil -> rinse it out after use
- NOT a scalp oil -> use on lengths only

It won't make your scalp oily and will wash out cleanly.

it's a pre-wash treatment
apply -> let it work -> shampoo out

🫧 for best results:
- leave on at least 1 hour (about 30 minutes under the hot booster cap) or
- apply the night before wash day for a deeper treatment
- shampoo scalp twice and always use conditioner to loosen up the oils
is it for my hair type?

Different hair types need different routines, but all hair lengths can become dry, weathered and more prone to breakage over time.

Our Pre-Wash Hair Oil is designed around that shared need. When it comes to oiling, we believe the more useful distinction is scalp vs. lengths. Your scalp and your hair fiber have very different needs, which is why we prefer to treat them separately rather than rely on one oil to do everything.

You simply adjust the amount to your hair: use less on fine or low-porosity hair, and more on thick, curly, porous or very dry lengths.

I am amazed

I am amazed. Truly. I keep touching my hair, it's so soft. I have double-processed bleached hair, and live in a dry climate. Most leave in conditioners made my hair sticky; with this, i keep touching my hair because it's so toussle-worthy soft. Seriously, thank you. Your new biggest fan.

Top producten!

Ik volg Niki al voor dat ze haar website lanceerde, haar filmpjes op TikTok & Instagram waren altijd met enorm veel goede info en gewoon ook duidelijk.
Ik heb net zoals haar, zeer poreus, droog haar en door haar olie tesamen met een heatcap, is dit gigantisch verbeterd!
Ik heb onmiddelijk de leave-in besteld omdat ik gewoon geloof in haar producten, ze heeft zoveel kennis en je weet gewoon dat ze deze producten met echte kennis en liefde maakt!
Ik ben fan & zal ook altijd je filmpjes blijven volgen voor de super interessante tips die je geeft!
You go girl ❤️

Forever buying this!

Ik zit al aan mijn 2e flesje. Wat een super fijne, niet overdreven vette olie. Ik merk echt nu al verschil in glans en gevoel in mijn punten. Ik heb fijn dun haar, dus alles wat ik eraan kan doen om lengte te behouden doe ik graag. Ik heb echt super veel aan het haar advies die Niki ook geeft op haar social media. Je merkt echt dat ze dit merk met passie heeft opgebouwd en het is te merken in haar producten! Super benieuwd naar alles wat nog gaat komen!
