Just amazing! I have always been so skeptical of lash serums but i did soooo much research before buying one and SOWN seemed to get amazing results but also seemed the safest to use on the eye area. I am so glad i tried this, it's become part of my daily routine!

I've tried most lash serums on the market... but Sown is the best lash serum out there. I mean JUST LOOK AT THEM! It's not only grown my actual lashes but suddenly loads of lashes appeared so the volume has been insane.

I had lash extensions and i took them off and looked like a naked mole rat so I stalked a bunch of lash serums trying to find a good lash serum and most importantly wanted one without prostaglandins. I am SOOO happy with the growth in 3 weeks!

My optician recommended Sown as a safe way to grow longer lashes and i'm SO pleased I took her advice. Trust the process, it really works. I didn't think they had grown that much then suddenly people were telling me how long my lashes looked so I knew it was working!

Sarah Croft

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

It starts at the roots

We work with award-winning trichologists and chemists who start at the base of all hair growth issues: the root of every hair.

[ba]

Because hair needs deep down nourishment. Like a plant it has to be nurtured and given the best conditions for growth. A tree is only as healthy as its roots.


That’s why Sown formulations contain a blend of root botanicals, multi-vitamins and amino acids to promote healthier, stronger hair growth with a trio of peptides sealing in moisture to prevent shedding and brittleness.


Long, luscious lashes and brows with science at the root.

Our Growth Guarantee

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.

The time before you see results can vary as it depends on what growth cycle stage your lashes are at when you start to use the product. 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. Learn how the lash cycle works, why timelines vary, and how Root 1 supports growth at every stage in our blog article.

Yes - SOWN serums are safe to use during pregnancy and breastfeeding. Our formulas are free from prostaglandins, hormones, and other harsh or harmful ingredients that are often flagged as unsafe. Instead, we use plant-based root botanicals, peptides, and vitamins that are gentle yet effective. As with any new product during pregnancy, we always recommend checking with your healthcare professional if you have specific concerns.

Yes, our serums are safe for contact lens wearers. However, it's advisable to apply the serum and allow it to dry completely before inserting contact lenses to avoid any potential irritation.

No, our 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 increased eyelid pigmentation, periocular volume loss (sunken, hollow eyes), 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.

No. Sown is100% prostaglandin-free, which means you won’t experience side effects like darkened eyelids, orbital fat loss, or iris discoloration — unlike many mainstream brands on the market.

Absolutely! Unlike a lot of competitors, SOWN is completely safe to use with additional beauty treatments such as lash lifts, extensions, tints and waxing. SOWN is oil free so safe to use with extensions. SOWN provides the perfect base to help your natural lashes stay strong during these treatments and so can enhance the length of time the treatments last on the lashes or brows. Also glue from extensions can take its toll on natural lashes, causing breakage and significant lash loss. Using SOWN to complement your lash extensions, strengthens your natural lashes so you can enjoy your extensions longer. You can even transition to natural lashes if you want to as SOWN is just that powerful!

All our products are made in the USA following the strictest of safety protocols and requirements in the world.

Yes! SOWN is formulated without prostaglandins, parabens, or any harsh irritants. It’s gentle enough for sensitive eyes, and many users switched to SOWN after reactions to other serums.

SOWN is formulated with clean, clinically proven ingredients like peptides and plant botanicals that nourish and strengthen the lash follicle —without the fluff or fake before/afters. It's designed to work for all lash types, especially short, brittle, or post-extension lashes.
