    Bright, bold and beautiful: mermaid eyelash extensions tried and tested

    Published on 1 April 2018 - Last updated on 19 December 2025 by Beth Ryan

    Mermaids and unicorns have been all over the beauty world recently. We’re talking rainbow highlighter palettes, mermaid hair, and now, coloured eyelash extensions, which really channel your inner 5-year-old. It’s the Instagram generation’s version of the early noughties blue mascara trend, and this is what you need to know about it.

    • 1 They're not too much for the office

      Mermaid extensions last for up to six weeks, so they'll need to be work-friendly. Happily, coloured lashes range from subtle to eye-popping, so you can choose a low-key pair if you need to. Also, some tones are mixed with black and have a subtle gradient, so they’re often only noticeable when the light hits them. Have a chat with your beauty therapist to find a set that won’t make your boss visibly blanche when she sees your latest look.

    • 2 They mean less time in front of the mirror

      Extensions make your lashes look thicker and longer so you can skip mascara if you want to. Purple extensions will also save you the effort if you're going for the full smokey eye look, as you're already half way there. If you like to get in touch with your artistic side when it comes to make-up, that's more time to experiment with creative eye-shadows.

    • 3 Expect a longer salon session

      It takes two hours to apply a full set. Each lash is attached one by one, and the colours are carefully chosen to blend into each other. If you're strapped for time you could go for infills, which are coloured lashes dotted between your natural ones. This takes just over an hour and gives a subtle look, leaving you with extra time to watch other people doing their own beauty routines on YouTube.

    FAQs

    How long do coloured eyelash extensions last?

    Coloured eyelash extensions can last for up to six weeks. This longevity makes them a convenient option for people who want a low-maintenance pop of colour. Proper aftercare helps keep them looking their best.

    Are coloured lash extensions suitable for the office?

    Yes, coloured lash extensions can be work-friendly. You can choose from subtle tones or sets that blend with black for a more understated look, making them noticeable only when the light hits them. This flexibility helps you find a style your boss will appreciate.

    How much time should you set aside for a full set of coloured lash extensions?

    You should allow about two hours for a full set of coloured lash extensions. Each lash is attached individually and colours are carefully blended to create a seamless effect. If you’re short on time, opt for infills, which take just over one hour.

    Can you skip mascara with coloured lash extensions?

    Yes, with coloured lash extensions, you can often skip mascara. The extensions make your lashes look thicker and longer, saving you time during your daily makeup routine. They can also enhance bold eye looks, like a smokey eye, without extra effort.

    What if you want a more subtle look with coloured lashes?

    If you prefer something subtler, you can choose lashes that mix colour with black or opt for infills. Infills involve coloured extensions dotted between your natural lashes, taking just over an hour. This approach offers a gentle hint of colour suitable for any occasion.
