The overall verdict? Well, it does come down to personal preference. You can't know how you feel about extensions until you've done them, and from there, you can decide if you want to trade in for the subtle volume of a lash lift or if you want to keep tweaking to find your perfect extension fit. "Everyone has their own idea of what they consider to be cost-effective — I think it’s all relative to a person’s lifestyle choices," Docrat says. "I’ve been doing both treatments for almost 10 years, and I can safely say that as long as you follow the prep and aftercare you shouldn’t cause any damage to your lashes." So, with that out of the way, why not spring for those extensions you can't stop thinking about?
