Prolong Lash Subscription

What's in the box: Expect lash extension aftercare such as Prolong's foaming lash cleanser and related care items, though the site does not spell out the contents of each shipment.

Prolong Lash is best known for its foaming eyelash extension cleanser. The brand says it made the cleanser after seeing clients lose lashes, get clumping and have slower natural growth within one to three weeks of getting extensions. The cleanser is oil-free and gentle. It is meant to remove protein buildup, debris, makeup and dead skin cells from the lash line, which helps extensions last longer and keeps the lash base clean. Besides the cleanser, the range includes a cleanser concentrate, care packs, a hypochlorous acid spray, a Prolong x Flutterstop collaboration and aftercare accessories. The brand says its products are not tested on animals and that it is registered with the FDA under MoCRA. The site prices in several currencies, including US, Canadian and Australian dollars, euros and pounds. Much of the site is aimed at lash technicians. It offers a partner program with business support and white label products. The site does not clearly explain how the subscription works, so check the delivery schedule, cancellation terms and what each shipment includes before you sign up. If you already wear extensions and go through cleanser regularly, automatic refills from a focused aftercare brand make sense. If you want variety or surprise items, this is not that kind of box.
