Grow, strengthen & target over plucked thin or sparse eyebrows, to reveal darker, thicker, fuller eyebrows in as little as 28 days.

Powered by RootBoost Technology: Clinically backed botanical, vitamin & peptide complex to stimulate the natural growth of your brows with scientifically proven ingredients and our trademarked Rootboost™ Technology.  Formulated with advanced polypeptides, root botanicals (Ginseng, Mulberry root and Liquorice) and amino acids promote healthier, stronger hairs. High-performance vitamins and pumpkin seed, rich in essential fatty acids and antioxidants, encourage healthy, thick and restored brows to help frame your face.

Developed with Experts: Award-winning trichologists, dermatologists & Ophthalmologist tested

Root 2 delivers 4-in-1 results:

  1. Encourages new growth
  2. Helps existing brow hairs grow
  3. Reduces brittleness by sealing in moisture
  4. Supports the brow cycle by extending the growth (anagen) phase

Most mainstream lash serums use prostaglandin analogues - hormone-like compounds originally found in glaucoma medication.

These can cause harmful side effects such as:

  • Eyelid darkening
  • Irritation and redness
  • Orbital fat loss (sunken eyes)
  • Iris color changes

They’re often hidden by brands under 15–20 confusing INCI names!

SOWN is 100% prostaglandin-free + hormone-free.
Safe for eyes, gentle on skin, and suitable for sensitive eyes + contact lens wearers.

Everyone. Those who want thicker, fuller brows or those with sparse brows who want some extra hairs in places. Regrows hairs damaged after microblading and chemo. Whatever the reason, we're here to get you fuller brows.

Using our engineered brush, apply directly to sparse areas or specific areas you want to grow. Use twice a day on clean, dry brows. You will see visible changes in the shape and fullness of your eyebrows within just 4 to 6 weeks.

Root Botanicals:

Thanks to my 2000s overplucking phase, I thought my brows were done for and was considering microblading but was terrified about permanently stunting hair growth. SOWN’s brow serum is the best serum i've tried - they’re so much thicker so look darker too now.

I had a few patchy areas on both brows particularly at the front and have been trying to even them up for ages. And OMG this stuff really works. I was thinking about getting microblading before but don’t need to now as they’re so EVEN now finally plus nice and full and bushy

I’ve always had one brow which is a bit uneven at the inner bit and have tried so many serums to grow it and nothing worked…except Sown! Obsessed!

How to Use

Application Time

3 seconds, 1 swipe, morning and night.

How to Make it a Habit

Keep it by your toothbrush to make it a root-ine!

01.

1. Apply 1 stroke stroke to both brows (1 dip into the bottle for both brows is enough), covering all the area you want to grow more hairs.

02.

2. Apply product to clean, dry brows, focussing on sparse areas. Use short, hair-like strokes starting at the root and working in the direction of hair growth.

03.

3. Allow the serum to dry a few minutes before grooming or styling your brows.

04.

4. Apply consistently, once a day for the first 3 months and then every other day for maintenance after the first full size bottle is finished.

How It Works

Good to Know: Hair Growth Cycle

Healthy hair go through a constant natural cycle of growth (anagen phase), transition (catagen phase), resting (where new hairs start forming beneath the surface, also known as the telogen phase) and release (exogen phase, where old hairs shed to make way for new hairs.) Sown extends the growth (anagen) phase but where your individual hairs are in this cycle will determine how soon you see results. This is why some people might start seeing results in week 2, whereas others don't until week 8!

What our derm says

This is one of the cleanest brow serums on the market, which actually works.

Regenerating RootBoost™ ingredients

Our RootBoost™ serums contain a powerful blend of botanicals including Ginseng, White Mulberry, Licorice, Red Clover and Pumpkin supercharged with vitamins B3, B5, B6, B7 (Biotin) C and E to promote healthier, stronger hair growth. A trio of peptides (amino acids) help seal in moisture to prevent shedding and brittleness. Most serums rely on synthetic shortcuts. We harness root botanicals, proven for centuries, and supercharge them with peptides and vitamins for visible, lasting growth.

No prostaglandins. No hormones. Just the proven power of roots.

Powered by Science, Balanced by Botanicals.

We use innovative clinically proven ingredients (that are responsibly sourced) blended with balancing botanicals for non-irritating, fast-acting formulas that aid hair growth.

  • Our boxes are 100% recyclable. The surface isn’t shiny or smooth because we don’t laminate them, meaning they can be easily recycled.
    They're also printed on FSC (Forest Stewardship Council) certified paper, meaning the forests that provide the wood for our paper are responsibly managed.

  • We believe in a circular economy, so all our serum tubes are made from 30% post consumer recycled plastic (RPET), made from fully recyclable PETG which means disposing in kerbside recycling is easy. Also the small slender shape means we ship easily & efficiently, minimizing our carbon footprint.

    We print directly onto all tubes and boxes to avoid sticky plastic labels.

More On Our Sustainability

Got questions? We've got answers.

Yes! Sown serums are safe to use with lash lifts, tints, and brow treatments like microblading and recommended by many technicians. Avoid using brow serums on freshly microbladed brows, especially during the initial healing period (usually 7-10 days). Once the brows are fully healed (after a few weeks), you can start using Root 2 as our formula is clean and doesn't contain any irritating ingredients and won't interfere with the pigment on your microbladed or tinted brows.

No, SOWN serums are 100% free from prostaglandin analogues and hormones. We believe in safe, effective growth powered by nature and backed by science. Many lash serums on the market use prostaglandin derivatives (often found in glaucoma medications), which can cause side effects like eye irritation, redness, or even changes in iris color. Our formulas are hormone-free and rely instead on a potent blend of root botanicals, peptides, amino acids, and vitamins to nourish and support natural hair growth—without compromising your health or safety.

Yes, our serums are ophthalmologist and dermatologist reviewed, making them suitable for individuals with sensitive skin or eyes. They are also fragrance free and have no irritants in. We also formulated them to be able to be in the CLEAN categories (this means super clean!) at SEPHORA, ULTA and CREDO. 

Just like no two plants sprout at the same speed, your hairs will grow on their own cycle. Some customers see results in 3 weeks, others closer to 12 — but follow our instructions carefully and growth will come. Consistency = your secret weapon.

    I see some new growth and I’m hopeful!

    I took pictures the first day and then the second set is on the third week of using Sown twice daily. I have tried many serums, and this is the first one that I could feel it working when applied. I am hoping with continuous use, I will have some brows! Thank You for making a great product!

    Really filled my brows out using this magic tube! 10/10

    Used for 12 weeks and saw considerable growth with lots of new hairs (its especially visible on both the top section of my brow as well as the front section). Definitely apply to clean skin/dry skin otherwise I feel it doesn't absorb so you don't get the benefits
