Our Sunday Salon DIY lash extensions are a different system from the pre-glued range: the clusters are bonded with a separate bond and finished with a sealant, and there is no clamp step. The full guide is on the Sunday Salon how-to page.
If a set has not lasted, run through these checkpoints:
An eye area completely clear of makeup and oil before you start. A thin, even layer of bond rather than a heavy coat. Letting the bond go tacky before placing the clusters. Finishing with the sealing step, as the sealant is what protects the bond. Keeping the lashes completely dry for the first 24 to 48 hours while everything cures.
Side sleeping is hard to avoid, but the Overnight Lash Guard Eye Mask helps protect the lashes in bed.
If you have followed all of this and the lashes still are not lasting, get in touch with your order number. You are covered by the money-back guarantee.
