What does 30D and 40D mean for lashes?

Lash terminology can be confusing, especially when numbers like 30D and 40D appear. What do these mean?

30D and 40D refer to the number of lash extensions applied to a single natural lash. These are mega-volume fans used for dramatic, full looks.

These numbers indicate extreme volume lashes, where multiple ultra-thin extensions (30 or 40) are applied to each natural lash. This technique creates an ultra-dense, fluffy effect, often seen in stage makeup or high-glamour styles.

What does DD mean in lashes?

Lash curl types range from natural to dramatic. Where does DD fit in?

DD curl lashes¹ have an extreme upward curve, creating a bold, lifted effect. They are curlier than D curl lashes.

DD curls are best for clients who want a striking, open-eye look. They are especially popular in volume and mega-volume sets. Compared to D curl, DD curl provides an even more intense lift, making them ideal for dramatic lash styles.

What are .07 lashes used for?

The diameter of lash extensions affects their weight and volume. What are .07 lashes commonly used for?

.07 lashes are used for volume extensions², allowing lash artists to create 2D to 6D fans¹ for fuller, lightweight lash sets.

.07 diameter lashes strike the perfect balance between thickness and flexibility, making them ideal for volume techniques. They are lightweight enough to form fans without overwhelming the natural lash.

Are C or D lashes better?

Choosing the right lash curl³ depends on the desired effect. But which is better: C or D curl?

C curls provide a soft, natural lift, while D curls offer a more dramatic, eye-opening effect.

The choice between C and D curls depends on the client’s eye shape and preference. C curl mimics a natural lash curve, making it ideal for subtle enhancements. D curl provides a more noticeable lift, making eyes appear bigger.

What does 5D lashes mean?

Lash fans come in different densities. So, what does 5D mean?

5D lashes⁴ refer to a volume fan with five extensions applied to each natural lash, creating a full yet lightweight look.

5D lashes add noticeable volume without looking too heavy. They are a great choice for clients who want a fuller appearance without going into mega-volume territory. Compared to 10D or 20D fans, 5D lashes strike a balance between drama and wearability.

Conclusion

Understanding lash terminology like 30D, DD curls, and .07 diameters helps in choosing the perfect set. Whether you prefer natural C curls or extreme mega-volume fans, selecting the right lash type ensures the best results.
