Losing your eyelashes and eyebrows during chemotherapy can feel like losing a part of your face. They frame your eyes, protect them and help you look like you, so it's completely natural to want them back as soon as you can. For most people, eyelashes and eyebrows start to grow back once chemotherapy finishes. Brows often return first, while lashes can take several months, and both sometimes come back thinner or patchier than before. Once your treatment has finished and your oncology team is happy, a gentle, hormone-free lash and brow serum, applied every day, can help your new lashes and brows grow in looking longer, fuller and thicker.
Here's what to expect as they grow back, when it's safe to start a serum, and how to care for them along the way.
Imagine the morning you look in the mirror and see your lashes framing your eyes again, and brows that make your face feel like yours. It's a small change that can make a big difference to how you feel, and every new lash is a step towards it.
Why chemotherapy affects your lashes and brows
Chemotherapy works by targeting cells that divide quickly, like cancer cells. Hair follicles also divide quickly, which is why many people lose the hair on their head, and often their eyelashes and eyebrows too. Not every treatment causes hair loss, and it affects everyone differently, so your care team is the best people to tell you what to expect from yours.
Will my eyelashes and eyebrows grow back?
In most cases, yes. Once treatment finishes, your hair follicles start to recover and new growth begins. Eyebrows often start to come back first, within a few weeks to a couple of months, while eyelashes can take several months to grow back fully.
Be prepared for your new lashes and brows to look a little different at first. They can grow back thinner, patchier, lighter or with a different texture, and for some people regrowth stays sparser than before. That's where gentle, consistent care can really help them look their best.

How to use lash and brow serums after chemotherapy
- Check with your oncology team first. Wait until your treatment has finished, and ask your team before using any new product near your eyes, especially if your skin or eyes are still sensitive.
- Start clean. Gently cleanse your eyelids and brows with lukewarm water and pat dry. No rubbing.
- Lashes: one stroke, upper lash line only. Draw Spectaculash along the base of your upper lashes once a day, ideally at night, just like liquid eyeliner. Keep it away from your lower lashes and waterline.
- Brows: morning and evening. Apply our Eyebrow Enhancing Serum along your brow line, focusing on any sparse or patchy areas.
- Be patient and consistent. Regrowth takes time, so use them every day and take a photo when you start. You'll be glad you can look back and see how far you've come.
What results to expect
Everyone's recovery is different, so be kind to yourself and give it time. With consistent daily use, Spectaculash helps lashes look longer, fuller and thicker in as little as 60 days, and our Eyebrow Enhancing Serum helps brows look fuller, thicker and more defined. Here's what our serums can do:

Caring for your lashes and brows while they grow back
Be gentle. New lashes and brows can be fine and fragile. Avoid rubbing your eyes, and remove make-up with a soft touch. Our dual-sided face cloths remove even waterproof mascara with just water.
Skip lash glue for now. False lashes and extensions put strain on fragile new lashes. If you want definition, a soft eyeliner along the lash line or a brow pencil can give you a lift while your own lashes and brows grow back.
Listen to your skin. Skin and eyes can stay sensitive after treatment. If anything stings or irritates, stop and speak to your care team.
Why choose our lash and brow serums?
Gentle, hormone-free formulas. Both our serums use peptide technology with no hormones and no prostaglandins. Some lash serums use prostaglandin analogues, which have been linked to irritation, eyelid darkening and even permanent changes in eye colour, so a prostaglandin-free formula matters, especially for eyes that have been through a lot.
Suitable for sensitive eyes. Spectaculash is suitable for sensitive eyes and contact lens wearers, and both serums are vegan and cruelty-free.
Trusted by CancerPal. Our lash and brow serums are also stocked by CancerPal, the online shop that brings together products to help people going through cancer treatment.
Better together. Our Lash and Brow Growth Serum Set gives you Spectaculash and our Eyebrow Enhancing Serum in one set for £44.99, with up to 60 days' supply of both. And if you use Spectaculash every day for 60 days and don't see noticeable growth, we'll give you your money back.
