It is possible that some clients have stronger follicle direction on one eye. If this is the case you might need to notate this on the client card and compensate for this when they come in by processing the stronger eye for longer.
Lash lifting can be affected by as little as 30 seconds. Therefore, you must be very specific about your timing.
If you have not symmetrically placed the lashes on the rods so that both eyes are the same and complimentary then this will be evident when the rods are removed and the lashes are dried. Taking a photo of your client’s eyes open before you begin the lifting process and refer to their iris location once the rod is on may help your lash placement.
Be mindful of your lash lifting adhesive usage. This product can create a barrier between the lash and the lifting or setting lotion. The adhesive has a setting time that allows you to roll the lashes up onto the silicone rod, however, sometimes the adhesive might set before all of your lashes are up. You can use a small amount more of adhesive but you need to be mindful of the placement of the adhesive – if you are coating the already well-placed lashes with adhesive those lashes might not lift.
