Star Features

Clears buildup without scrubbing · Comfortable on a dry or sensitive scalp · Fragrance free · Vegan · Eight ingredients · 100% natural origin

Key Ingredients

Lactic Acid · Sodium Hyaluronate · Nettle Leaf Extract

Why it Works

Sometimes the scalp doesn't need scrubbing, it needs gentle exfoliation. Clear Serum uses lactic acid, a mild acid of the kind used in facial skincare, which lifts away product residue and dead skin cells without scraping.

To keep the scalp from feeling tight, it contains hyaluronic acid, which holds in hydration, and organic nettle extract. It has no fragrance and is vegan.

100% naturally derived ingredients, certified ECOCERT COSMOS Natural.

Aroma

Fragrance free. No perfume and no essential oils, because fragrance is the most common cause of scalp reactions in cosmetics.

How to Use

Apply on dry

Part your hair and apply straight to a dry scalp, section by section. Dry is deliberate: with no water competing, the acid works on the buildup and nothing else.

Wait five minutes

Three to five minutes is all it needs. Nothing to rub, nothing to massage in. The lactic acid loosens the residue while the hyaluronate holds water at the surface.

Rinse and wash

Rinse thoroughly and shampoo as usual. The scalp is left clean and comfortable rather than stripped, and the roots have nothing sitting on them.

At NUDA, every ingredient has a reason to be there. We source from Northern European ecosystems, where nature works harder, and so do we. No fillers, no shortcuts. Just pure, active ingredients that your hair can actually feel.

Most of our formulas are certified by ECOCERT under the COSMOS standard. Each product page states whether that product carries the seal, and every page publishes the full INCI list.

Nothing to hide. Everything to give.

Questions about this product

Is lactic acid the same as salicylic acid?
No. Both exfoliate the scalp, but they work differently. Salicylic acid is oil-soluble and gets into the follicle, which suits an oily, flaky scalp. Lactic acid is water-soluble and works on the surface, gentler and better suited to a dry or sensitive scalp. This formula uses lactic acid.
How often should I use it?
Once or twice a week. Apply to a dry scalp, leave for 3 to 5 minutes, then rinse thoroughly.
Will it dry out my scalp?
No. Sodium hyaluronate holds water at the surface while the lactic acid works, so the scalp stays hydrated rather than stripped.
Is it certified?
Yes, ECOCERT COSMOS Natural, and the formula is 100% natural origin. The full INCI is published on this page.
What does lactic acid do on the scalp?
It exfoliates gently: it helps lift away product residue and dead skin cells that build up at the root, without rubbing or scraping.
Why does it have no fragrance?
Because it's a treatment that stays in contact with the scalp, and without fragrance it's more neutral. If you like unscented products, this is the one for you.

Questions

Honest answers.

7 questions
What is NOT in our products?

What a product leaves out says as much as what it contains. At NUDA:

  • No silicones
  • No parabens
  • No mineral oils (no paraffin, no petrolatum)
  • No microplastics
  • No artificial colorants
  • No drying alcohol (except Dry Bath*)

And the products with ECOCERT COSMOS certification, which is most of our range, also leave out synthetic fragrances.

* Dry Bath is a dry shampoo, and the alcohol is what makes it evaporate in seconds and leave hair dry instantly. It is the only product in the range that contains it.

Every NUDA product contains botanical actives, and we always look for ingredients of natural origin and, where possible, from organic farming. We keep working to make each formula purer than the last.

Why did we choose these ingredients?

Because we believe healthy hair matters as much as good-looking hair. Many products look good on day one because they cover up: silicones that fake softness, mineral oils that fake shine. The good look lasts only until it builds up.

We prefer ingredients that actually work:

  • Chanterelle extract and keratin to add body, instead of silicones that weigh hair down.
  • A rapeseed-derived conditioning agent to detangle and soften, instead of silicones that build up.
  • Ground cherry seed and clay to exfoliate, instead of microplastics.
  • Organic oils instead of mineral oils, like in Vivid Serum, which combines seven different organic oils.
  • Organic black tea and blueberry as antioxidants.
  • Lactic acid to deep clean the scalp without scrubbing.

Every ingredient is listed in full on each product page, so you know exactly what you are putting on your hair.

What certification do our products have?

Most of our range is certified by ECOCERT, an independent body that reviews every formula, every ingredient, and how it is made. If everything meets the COSMOS standard, the product gets the seal. A brand cannot award it to itself.

There are two levels:

  • COSMOS Natural: ingredients of natural origin, and no silicones, parabens, mineral oils, synthetic fragrances, microplastics, or artificial colorants.
  • COSMOS Organic: all of the above, plus a minimum percentage of ingredients from organic farming. The most demanding level.

The COSMOS standard does not only look at ingredients, it also regulates how they are processed and what materials can be used in packaging. Each product page shows whether that product carries the seal and which one, along with its percentage of natural-origin ingredients and the full ingredient list.

Do you use sulfates?

In two of our shampoos, Bloom Bath and Gloss Bath, yes. It's a decision we made after comparing many formulas and testing many shampoos. It might sound like a contradiction for a brand as clean as ours, but this is what we learned:

There's a belief that all sulfates dry out your hair, but we've found that only the harshest ones do. That's why we use Sodium Coco-Sulfate, a cleanser of natural origin that comes from coconut and is approved by the ECOCERT COSMOS standard for certified natural cosmetics. It cleans properly without drying out the hair: it removes the product residue and oil that make hair dull and flat. We pair it with very mild plant-based and amino-acid cleansers, so your hair is left clean, light and soft.

The result is two shampoos that clean properly, with exceptional purity: Bloom Bath has 99% ingredients of natural origin, and Gloss Bath 98%. Both are certified ECOCERT COSMOS Natural.

Are your products vegan?

Many are, and each product page states whether that product is.

The ones that are not, for one reason only: hydrolyzed keratin, which comes from wool. It is the only animal-origin ingredient in our entire range, and we use it in Bloom Bath, Bloom Balm, Deep Mint, Silk Mist, and Rescue Mask.

We could remove it and put a vegan seal on the whole range. We do not, because it is the best ingredient we have found to add body to fine hair and restore strength to damaged hair. We keep looking for plant-based alternatives that work just as well.
