How to look after your Eyelash Extensions | Extensions By Ally

Brushing Eyelash Extensions

You may be brand new to lashes, or perhaps you are a regular lash connoisseur. Regardless of how familiar you are, it's important that you have all the right information to help you take care of your lashes.  

Lash extensions are delicate things and do need a little TLC to ensure that they last well. The answer to ‘How long will they last?’ is hugely variable – it mostly comes down to you and what you do (and don’t do) to them.

There are three main reasons you would want to look after them properly:

  1. Your lash health: If you regularly do bad things to them as listed below, it can compromise your lash health and slow down the growth of new lashes. Your eyelids can become itchy from the buildup of dead skin, if they are not cleaned regularly.

  2. They will look better for longer: Eyelash extensions that have been coated in mascara, oily makeup and strip lashes don’t look that great.

  3. Refill cost and financial/time factors: If you look after your lashes and retain them well, you won’t need to come in as frequently or for extended refill appointments, which will save you money.  


  • Keep them as dry as possible for at least 24 hours. This means, it’s ideal for you not to wash your hair during this time. However, if you need to, use only lukewarm water, and keep water off your eyes. This also includes avoiding steamy environments, very hot showers, spas, saunas etc. for 24 hours as a minimum. If it’s a very hot and humid day, try to stay out of the heat. All of this will allow the adhesive to cure as strongly as possible.

Makeup Removing Cleanser (foamer)
  • After the 24 hour mark, they are technically waterproof, however, if you are swimming  or sitting in a hot spa daily, they probably won’t last quite as long as if you didn’t.

  • If you have a very oily face, try to control this as much as possible with blotting papers, mattifying lotions etc. and by using oil-control moisturizer.

  • Clean your eyes properly, at least a few times a week, with a foaming lash cleanser. I recommend Mojé Makeup Removing Cleanser (foamer).

  • Let me know before your refill if you think you will need more time because you have lost more lashes than expected, or want to upgrade to a thicker set/more lashes.


DON'T - pick at eyelash extensions
  • Try not to touch your extensions, particularly during the first few hours. The more you touch them, the more oils from your fingers get on them.

  • Do not play with or pick at your lashes, or rub your eyes roughly. If you are a picker, it can really damage your natural lashes.

  • Do not use oily products on your face.

  • Do not use waterproof or oil based mascara or eyeliner (I stock a range of suitable makeup items).

  • Do not use baby wipes/makeup wipes/cotton pads to wipe makeup off your extensions.

  • Do not try to remove the extensions yourself – as it may damage your natural lashes. I can remove them for you if you wish.

  • Do not use cleansing oils, coconut oil etc. on your face if you want the extensions to last.

  • Do not put strip lashes on top of them unless you are prepared to lose a few of your own lashes when you try to take them off.

  • Do not try to light a cigarette on your toaster or stove-top (good life advice generally – but will also stop your lashes getting singed and frazzled on the ends!)

What is normal:

  • Immediately after the lash application, some individuals with sensitivities can experience minor redness and dry eye. I try to minimize this where possible by asking if you are sensitive beforehand. In most cases, this disappears within an hour or so and there’s no need to worry. Of course, call me if you are concerned.

  • It’s normal to lose a couple of lashes every day (1-5). Don’t be alarmed if you notice them from time to time (as they are much larger than your natural lashes). The extension falls out attached to the natural lash when it is ready to come out, and a new baby lash takes its place. Some days you won’t lose any, other days you might lose 3 or 4. It’s completely normal and does not mean your eyelashes are all going to fall out!

  • Some lash growth cycles are faster than others. You may find every few months, your lashes shed faster than other times. It usually means that you have a lot of new growth, and when you come in I will see a lot more lashes that I can lash! Other times they might still look great at 4 or 5 weeks, as they have not shed much.

  • No two sets of lashes are identical. I customize the styling, sizes, weights and curls to every individuals eye shape, natural lash condition and tastes. Each style looks different depending on their own eye shape. So please be aware that your lashes will not look identical to your friends, even if you request the same thing.

  • Expect between 2 – 4 weeks before you need a refill. On average, my clients come back every 3 weeks. Sets consisting of more lashes (Extreme Volume) will usually last longer than those will less (Natural Volume).  Shorter lashes usually last longer too.

What’s not normal

  • If you experience intense itching and or red/swollen eyelids in the first few days after the application. This could be an allergic reaction. Unfortunately, these are largely unavoidable – but luckily they are rare, and can be treated. Please contact me if you are worried.

  • Excessive shedding of extensions in the first few days. This is uncommon – but please contact me if you feel they are shedding rapidly within the first 3 days of application so I can troubleshoot and/or assess your lashes.

  • If (after wearing extensions for a while) you find your eyes sometimes feel gritty and sandy – this can mean that you really need to clean your lashes more frequently/properly. I can assess your lash line and give advice on the best way to clean your lashes.


If you wish to maintain your extensions, you will require to refill your lashes, usually between 2-4 weeks time, depending on factors such as:  

  • How you treat them

  • Your lash cycle and how fast you are shedding/growing lashes

  • Your skin type (oilier complexions usually shed lashes faster)

You session will be considered a refill if you book you appointment within 4 weeks to your prior appointment and as long as at least 1/3 of the extensions have been retained well. Please let me know in advance if you think you will need more time than usual.  

Before you come for your next refill:

  • It’s wise to book in advance – particularly for evening and weekend bookings – these times are most popular and can book out weeks in advance.

  • Let me know if you would like anything changed, for example if you would like to upgrade to a thicker set. As I will need more time for different types of extensions.

  • Avoid coming in with makeup or oil based facial products. You will be required to wash your face prior to the application.

  • Make sure you aren’t wearing any eye makeup, that your eyes are perfectly clean. Unclean lids and lashes (particularly things I can’t see like lash mites – they thrive when lashes are never cleaned!) will prevent extensions from bonding well, and they may not last long.
