All lash lifts work by adhering the lashes onto a mold, breaking the disulphide bonds of the hairs/lashes and then reforming those bonds keeping them locked in the new shape. So what's the difference between a Traditional and Keratin Infusing Lift? We're breaking down the pros and cons in this blog.
Traditional Lift
Pros:
Lower Cost
Can get wet anytime after the service, though we strongly recommend waiting 4 hours so the leave in conditioners can provide maximum benefit
Cons:
Uses ammonium thioglycolate which is harder on the lash and carries a risk of over processing (though minimal at The Sassy Lash Studio as we closely monitor the lash condition throughout the procedure)
The lift is limited to the lower portion of the lashes as the solutions are too strong to apply to the ends.
Dehydrates the lashes
Requires glue and tension on the lashes which can weaken them.
Deep conditioning vitamin lash treatment is applied at the end of the service after the cuticle is closed limiting its restorative effects.
Cannot be repeated more often than 6 weeks to avoid over-processing
Keratin Infusing Lash Lift
Pros:
Uses pure cysteamine instead of ammonium thioglycolate so there is no risk of over processing
The entire lash can be safely reshaped from root to tip
Can be repeated as often as desired (but 8 weeks is typical)
Can be used to correct an overprocessed, or awkwardly growing out traditional lift
Damage Free
Made from EWG green grade raw materials
Pure Cysteamine System
Keratin infusion step that rebuilds hairs from the inside out + increases follicle growth is applied while the cuticle is open maximizing its benefits

May be able to help repair an overprocessed lift (evaluated on a case by base basis, please contact us for a consultation)
Can utilize the latest innovative Korean Lash Lift techniques due to how gentle it is on the lashes. This technique allows for more precise placement, eliminates the need to use glue, apply tension or create friction during the lift further preserving the health of the lashes.
Cons:
Higher Price
It is recommended to keep the lashes dry for 12 hours, cleanser swimming or steam for 24 hours.
Conclusion: Both are great services and can even be alternated to get the best of both worlds! To really protect and fortify the lashes, the Keratin Infusing Lift is the winner!
