This UKLASH review starts with a simple question: can a serum you swipe on in five seconds actually change how your lashes and brows look? UKLASH has built its whole identity around answering yes. The brand bills itself as the UK's number one lash and brow serum brand, and its site goes further, calling its range the world's no.1 rated lash, brow and hair serums. Those are big claims, so we dug into the formulas, the published results figures and the product line to see what actually backs them up.
The short version: this is a focused brand doing one thing with unusual discipline. The formulas lean on named, clinically studied ingredients rather than vague botanical promises, the results claims come with specific percentages and timelines, and the range has expanded logically from lashes into brows and hair without losing the plot.
Who UKLASH is and what it stands for
UKLASH describes its approach as clinically proven ingredients backed by industry experts and biologists, with products that work to create longer and healthier lashes, brows and hair. The brand's tagline, Never Stop Growing, tells you what the whole catalogue is chasing: growth you can see, supported rather than faked.
Product tags across the range point to vegan and cruelty-free formulations that skip parabens, and the hero Eyelash Serum carries a money back guarantee. That last detail matters in this category, because growth serums ask for weeks of daily commitment before you can judge them. A brand that refunds you if it does not work is carrying some of that risk for you.
The UKLASH review of the hero: the Eyelash Serum
The original Eyelash Serum is the product that made the brand, and its ingredient list is where UKLASH separates itself from filler serums. The formula is built on Biotin Peptide, Vitamin B5 (Panthenol), Green Tea Extract and Myristoyl Pentapeptide-17, an amino acid peptide known for stimulating keratin growth.
The results claims are specific rather than fluffy: the brand reports 85% longer lashes and 86% fuller brows in as little as 25 days when the lash and brow serums are used daily, and elsewhere cites 85% longer-looking and 80% fuller-looking lashes for the serum on its own. Application is genuinely low effort, taking less than five seconds a day. For anyone weighing this against home remedies, our guide to castor oil for eyebrow growth is a useful contrast: the DIY route has tradition behind it, while UKLASH is betting on measured peptides.
There is also a Complex Peptide Lash Growth Serum for those who want the science-driven upgrade, which the brand says supports longer, fuller-looking lashes in as little as six weeks with the same five-seconds-a-day routine. If you like the idea of a serum but want to see the range first, you can browse the full lineup at UKLASH.
Instant results: Lash Lift Gel and the mascaras
Growth serums are a long game, and UKLASH clearly knows that people want something to show today. That is the job of the Lash Lift Gel, a hybrid formula that combines the care of a nourishing lash treatment with the performance of a lifting primer. The brand reports that 82% see visibly lifted lashes instantly. It is powered by Vitamin E, Glycerin, Hexapeptide-1 and Caramel, and you can wear it alone for a no-makeup makeup look or under mascara as a lifting primer.
The Tubing Mascara is the other standout. Instead of painting lashes with pigment that smudges, it wraps each lash in polymers using a precision pine cone wand, giving a longer-looking, panoramic lash effect that is smudge-proof and long-lasting, yet removes with just warm water. It comes in Black and Mocha and is enriched with Arginine and Shea Butter, so every wear nourishes rather than strips. Gentle removal is the quiet hero here: less tugging at the lash line means less damage to the lashes you are trying to grow.
There is also a Volume Boost Mascara enriched with Vitamin E, Keratin and Vitamin B5 for a fuller, bolder look, plus a c-curve Eyelash Curler designed to lift and curl before the gel locks the shape in.
UKHAIR: the same logic, applied to your scalp
The newer UKHAIR line extends the growth philosophy from lashes to hair, and it is more complete than a token line extension. The Hair Growth Serum uses clinically studied actives including AnaGain (Pea Sprout Extract), Turmeric and Lemon Fruit Water to support the scalp and reduce breakage.
The Advanced Hair Supplements attack the problem from the inside. The sugar-free capsule format is designed for rapid nutrient delivery, with Biotin, Bamboo Extract, Vitamins C and E, and AnaGain NU, which the brand reports helped 86% of participants experience a reduction in hair loss after two months. There is a 90-day supply designed to cover a full growth cycle, an Advanced Scalp Dermaroller to help stimulate the scalp and enhance serum absorption, and even a limited edition Scalp To Strand Set made in collaboration with Tangle Teezer, pairing the serum with The Ultimate Detangler Extra Gentle to reduce tension and breakage. If thinning hair is your main concern, our roundup of the best products for thinning hair puts this category in wider context.
What we like, and what to keep in mind
- Named actives with numbers attached. Biotin Peptide, Myristoyl Pentapeptide-17, AnaGain: the formulas cite specific ingredients and specific results percentages, not vibes.
- Instant and long-term options work together. Serums handle the weeks-long growth journey while the Lash Lift Gel and Tubing Mascara make lashes look better today.
- Gentle by design. Warm-water mascara removal and vegan, paraben-free, cruelty-free formulations protect the lashes the serum is building.
- Money back guarantee on the hero serum. A meaningful promise in a category that demands patience.
- Commitment required. The published timelines are as little as 25 days for the serum duo and six weeks for the Complex Peptide Serum. Daily consistency is non-negotiable, and results language is about longer-looking and fuller-looking lashes, not miracles.
The sets are the smartest way in. The Champions Trio bundles the number one rated Lash Growth Serum, Eyebrow Growth Serum and Tubing Mascara so you can grow and show results at the same time, while the Lash Journey Kit pairs the serum with the curler and Tubing Mascara, a combination where the brand reports users saw 95% longer-looking, 95% visibly lifted and 95% more volumised lashes. You can compare all the bundles directly at UKLASH.
