M-curl

M curl lash extensions have a straight base that sweeps upwards, giving lash artists a way to create a defined lift or a soft eyeliner effect. The shape can work well on straight or downward-pointing natural lashes when the base aligns with the natural lash and the tips clear the eyelid.

Explore M curl options across Mayfair faux mink and Kensington trays for classic, hybrid and volume sets. Choose your diameter, length and tray format according to the technique and what your client’s natural lashes can support.

What Is an M Curl Lash?

An M curl extension starts with a straight section before sweeping upwards. That shape gives it a different profile from a rounded C curl, which curves more gradually from base to tip.

• Straight base: Can provide good contact where it aligns with a straight or downward-pointing natural lash.
• Upward sweep: Creates visible lift with a softer transition than a sharply angled L curl.
• Forward projection: Can help the tips clear the eyelid fold. Check the fit on the individual client before mapping the full set.

M Curl vs L Curl, LC Curl and C Curl

Choose a curl based on the finished look, the direction of the natural lashes and the clearance around the eyelid. Curl profiles can vary between ranges, so compare the trays you plan to use.

Choosing M Curl for Your Client’s Natural Lashes

• Downward-growing lashes: M curl can give visible lift where its straight base aligns with the natural lash. Check base contact before committing to the map.
• Straight or horizontal lashes: The upward sweep can add definition without relying on extra length for the effect.
• Hooded or deep-set eyes: M curl can be a useful option when you want the extension to project forwards before lifting. Check that the tips clear the lid fold when the client opens their eyes.
• Upward-growing lashes: A strong lift may bring the tips too close to the eyelid. Consider a softer curl if it gives better clearance and suits the look.

M Curl Thicknesses and Tray Formats

Choose your diameter based on the length, the number of fibres in the fan and the condition of the natural lash. Check the product page for the M curl lengths and diameters available in each range.

• Volume: Consider fine diameters such as 0.06 mm or 0.07 mm for handmade fans. Match the finished fan weight to the natural lash.
• Light volume, hybrid and wet-look sets: Consider intermediate diameters such as 0.085 mm or 0.10 mm where available and suitable for the technique. For a soft classic finish, you can also consider a 0.10 mm or 0.12 mm single extension.
• Classic 1:1: Thicker single fibres, such as 0.15 mm, 0.18 mm or 0.20 mm, can give a bolder finish where the natural lash can support them.

Compare Kensington 0.07 mm 20-line trays and Mayfair 0.07 mm faux mink trays for your volume work. Check the curl selector and available single-length or mixed-length formats before ordering.

Mapping Tips for M Curl Lash Extensions

• Compare the visible length: M curl can sit differently on the eye from a rounded curl of the same labelled length. If you’re switching curls, compare a slightly shorter length before finalising the map.
• Build an eyeliner or fox-eye effect: Start with shorter lengths through the inner and middle sections, then build towards the outer third where the natural lashes can support it. Adjust the outer lengths if they would pull the look down.
• Blend curls gradually: When mixing M curl with rounded curls, check the tips across neighbouring sections and layers. A gradual transition can help avoid a visible step in the finished lash line.

Frequently Asked Questions

What are M curl lashes?

M curl lashes are extensions with a straight base that sweeps upwards. The shape can create a defined lift on straight or downward-pointing natural lashes when the base fits and the tips clear the eyelid.

What’s the difference between M curl and L curl?

Both start with a straight base. L curl typically has a more angular transition, which suits a sharper eyeliner effect. M curl has a softer upward sweep for a more blended finish. Compare the actual trays, as profiles vary by range.

Can you use M curl on hooded eyes?

Yes, M curl can work well on some hooded eyes. Its base projects forwards before lifting, which can help the tips clear the lid fold. Check the natural lash direction, length and eyelid clearance before choosing the curl.

Are M curl lashes suitable for classic and volume sets?

Yes. M curl describes the shape of the extension. Choose the diameter and length for your technique, whether you’re placing single fibres for a classic set or building lightweight volume fans. Check the individual tray for available options.
