What STACY LASH Makes

STACY LASH is a lash supply brand that holds the top-selling position in the eyelash extension and lash care category on Amazon, according to the brand’s own storefront description. The company sells a full professional supply range: shampoos for daily lash maintenance, adhesives across multiple formulations, primers and prep products, growth serums, and lash lift kits.

The brand ships across the US and Canada through both Amazon and its own website at stacylash.com. Products are manufactured in what STACY LASH describes as “top-tier, certified facilities” and are described as meeting FDA and OSHA requirements. The adhesive range carries formaldehyde-free formulations, which is a meaningful differentiator in the extension adhesive category.

One critical note before discussing products: STACY LASH adhesives are, without exception, intended for professional use by licensed lash technicians. The brand is explicit on this point and it belongs at the front of any honest review.

Lash Shampoo and Daily Care

The entry point for most buyers is the Lash Shampoo Kit, which is the brand’s anchor product and its most reviewed item on Amazon. The 50ml Korean-formula kit includes spoolies, a rinse bottle, a cleansing pad, and a brush — everything needed for a cleaning routine that keeps extension bonds intact.

The 4.6-star average from over 22,900 Amazon ratings places this among the most strongly-reviewed lash care products on the platform. The shampoo is described as suitable for use on eyelash extensions, cluster lashes, and natural lashes, making it a single purchase that covers multiple lash formats.

For those building a routine after getting extensions applied professionally, the best lash shampoos roundup covers the broader category and how STACY LASH fits alongside other options.

STACY LASH also offers the shampoo bundled with their growth serum in larger sizes — a 50ml shampoo packaged with a 5ml serum — for clients who want both daily cleansing and a growth support treatment in one order.

Professional-Grade Adhesives

The adhesive range is where STACY LASH’s reputation as a professional supply brand becomes most apparent. Three primary formulations cover different working speeds and experience levels.

The Sensitive Glue (5ml) is the starting point for many lash artists working with new clients or in lower-humidity environments. It offers a 1–2 second drying time and a claimed up to 5 weeks retention — the longer dry time allows more precise placement before the bond sets. It holds 4.1 stars from over 8,200 Amazon reviews.

The Lightning Speed Glue (5ml) is a different tool: a 0.3–1 second drying time and a claimed up to 8 weeks retention, designed for experienced technicians processing volume sets efficiently. It holds 4.3 stars from 2,500+ reviews. The Extra Strong Glue sits at the top of the retention range with a claimed 8-week hold and a 0.3–1 second dry time.

A safety note that cannot be stated lightly enough: STACY LASH is direct on its FAQ that these adhesives are Cyanoacrylate-based and “not hypoallergenic.” The brand requires professional application — DIY use “can lead to serious reactions and irritations,” per STACY LASH’s own guidance. No removal should be attempted at home.

Prep Products and Serums

The Primer (15ml) is a preparation product that STACY LASH describes as a protein and oil remover — the step applied before adhesive to increase bonding strength and extend retention. It carries 4.7 stars from nearly 300 reviews, the highest rating in the current catalog.

The Korean Lash Serum (5ml) is formulated for natural lash and brow growth and thickness. It is one of the few STACY LASH products positioned for use outside a professional service setting — buyers use it between appointments to support natural lash health.

The Korean Lash Lift Kit covers 10 sets of lash perm and brow lamination and includes silicone shields, eye pads, and brushes. The brand describes it as suitable for both professional and DIY home use — a distinction worth noting, as it sits differently from the extension adhesives in STACY LASH’s lineup.

Shipping, Returns & Warranty

STACY LASH products on Amazon ship under Amazon’s standard fulfillment terms. Returns follow Amazon’s return policy for the relevant product category. For purchases through stacylash.com, the brand ships across the US and Canada with its own fulfillment terms posted on the site.

Is STACY LASH Worth It vs. Alternatives

In the professional lash supply space, the most frequent comparisons are with BL Blink and Lashify. BL Blink is a long-established Korean adhesive brand with a large professional following and a similar Cyanoacrylate formula. Lashify occupies a more consumer-facing position with its Gossamer cluster system designed for home use.

STACY LASH’s advantage over both in the professional adhesive category is its breadth across retention speeds and its shampoo line’s volume of Amazon reviews — a signal of consistent client-facing use. For lash salons stocking a supply closet, STACY LASH offers the option of buying adhesive, primer, shampoo, and serum from a single storefront.

STACY LASH describes the Primer as a 'Super Primer/Cleanser' that removes protein and oil residue from natural lashes before adhesive application. The brand states it increases adhesive bonding power and retention. It is intended as a prep step before applying extension adhesives.
