The Story

A lightweight leave‑in spray that thickens, detangles and strengthens hair with five targeted benefits. Formulated with biotin, hydrolysed collagen and coffee seed oil to add body, reduce breakage and control frizz. Provides thermal protection for styling tools while delivering light hydration and improved manageability. Designed for Unisex use and daily styling rituals where texture, resilience and easy detangling matter.

Shake well. Spray 15–20 cm from towel‑dried or dry hair, focusing on mid‑lengths to ends. Comb through and style as usual. Reapply sparingly to dry hair for refreshes.

Key actives: biotin to support visible strength, hydrolysed collagen to boost body and coffee seed oil for light emollience. Glycerin provides hydration; silicone quaternium‑22 smooths cuticle and aids frizz control. Formulated without animal testing.

About Hask

Hask: Pioneers of Targeted Hair Care

Provenance: United States

HASK is a U.S.-based hair care brand positioned around performance treatments and category-specific formulas. Its assortment on Ellie Jules focuses on shampoo, conditioner, masks, oils, leave-in sprays, and scalp care, with lines such as Argan Oil, Biotin Boost, Blonde Care, Curl Care, Keratin Protein, Macadamia Oil, Monoi Coconut Oil, and Texture.

The brand’s website presents HASK as “powered by performance treatments that work,” with targeted formulas designed to address specific hair needs. Its core philosophy is practical and ingredient-led, offering reparative and texture-focused care across a broad range of hair types. Within the catalogue, Argan Oil Repairing Shampoo and Argan Oil Repairing Conditioner reflect the brand’s repair positioning, while Texture Hair Detangler and Strengthening Scalp Oil Hair and Scalp Oil extend that remit into styling and scalp support.

HASK matters because it occupies the accessible, treatment-driven end of modern hair care while maintaining a clear focus on function. For shoppers seeking formulas built around specific concerns rather than generalized care, it remains a recognisable American name in targeted hair treatment.
